 1. OBJECT   
 
This Standard lays down the minimum limits of efficacy and the classification of energy efficiency for 
integrated compact fluorescent lamps1) (ICFL), and also the user safety specifica tions and the 
applicable approval procedures for verification of these specifications. In addition, it lays down the 
type of information that must be provided for  products covered by this standard which are sold within 
Salvadoran territory and addresses th e need for such products to promote efficient use and saving of 
energy.  
 
 
2. SCOPE  
 
This Standard applies to all integrated compact fluorescent lamps (ICFL) without an envelope, with an 
envelope or with an integrated reflector with an Edison E -12, E -14, E -26, E-27, E -39 or E -40 cap, or a 
bayonet B -22 cap, for input voltages of 120 V to 240 V AC and 60 Hz, which are manufactured, 
imported or sold within the national territory.  
 
 
2.1 Exceptions  
 
This Standard does not include integrated compact fluorescent lamps (IC FL) whose bodies incorporate 
control accessories such as photocells, movement detectors or radio controls. It also excludes modular 
compact fluorescent lamps.  
 
 
3. DEFINITIONS  
 
3.1 Ballast:  electromagnetic, electronic or hybrid device which limits the lamp cu rrent and when 
necessary the voltage and lighting current by means of inductances, resistors and/or electronic 
elements (transistors, thyristors, etc.), alone or in combination. Electromagnetic and hybrid ballasts 
have an output frequency of 60 Hz. Electro nic ballasts are ballasts that have at least one internal 
frequency converter.  
 
3.2 Cap:  device for connecting the lamp to the power source; may be a screw fitting or come 
equipped with terminals.  
 
 
3.3 Power factor correction capacitor:  capacitor used in a ma gnetic ballast, which may be 
connected:  
 
a) to the lamp or lamps, and supplies the ballast impedance for the lamp current, or  
b) for power factor correction, via the ballast input conductors or via an extension of the primary 
coil. 
 
3.4 Colour:  the appearance  of the light emitted by a lamp  
 
3.5 Nominal colour:  apparent colour stated by the maker or the colour marked on the lamp 
(degrees Kelvin °K). There are two ranges, recognised as: warm light (2700 °K) and cold light 
                                                   
1)   Integrated compact fluorescent lamps (ICFL) or Self -ballasted compact fluorescent lamps (SCFL)  NORMA SALVADOREÑA                                                                                         NSO 29.47.01:07

 (6500°K) 
 
3.6 Total harmonic distortion (THD): the percentage of distortion of the current sine wave 
(THDI) or the current voltage (THDV) caused by the presence of electric senoidal signals with 
different frequencies and multiples of the fundamental frequency.  
 
3.7 Efficacy:  the ratio between the total light  flow emitted by a source and the total power 
consumed, expressed as lumens per Watt (lm/W).  
 
3.8 Energy efficiency:  ratio between the energy taken up and the total energy used in any process 
within the energy chain.  
   
Note 1.  In the case of electric lamps, energy uptake is directly determined by the amount of light flow that it is capable of 
delivering.  
 
3.9 Integrated compact fluorescent lamp (ICFL):  a lamp incorporating an electronic ballast, also 
known as a self -ballasted compact fluorescent lamp (SCFL); it i ncorporates a non -replaceable compact 
fluorescent lamp, and additionally the elements necessary for ignition and stable operation of the light 
source, which cannot be separated without suffering permanent damage. This includes circular and 
linear tube type  lamps with a double cap.  
 
3.10 Wet places:  interior or exterior locations which are regularly or periodically subject to 
condensation of moisture in or on electrical equipment, including locations partially protected by 
canopies, open -roofed arcades or the lik e. 
 
3.11 Damp places:  locations where uncontrolled liquids may spill, splash or drip on to electrical 
equipment.  
 
3.12 Dry places:  locations which are not normally exposed to damp, but may include locations 
subject to temporary damp such as buildings under construct ion; in such cases it is important to have 
proper ventilation to prevent the build -up of moisture.  
 
3.13 Lamp cap:  Edison -type cap which can be fitted to power an integrated lamp.  
 
3.14 Modular system:  one composed of an adapter and a replaceable compact lamp.  
 
3.15 Nom inal voltage:  the voltage indicated by the maker  or distributor on the product label.  
 
3.16 Test voltage:  the accepted test voltages for ICFLs are: 120 V, 127 V, 220 V, 240 V, 254 V, 
277 V.

6.2.4     Dielectric withstand voltage (Applied potential)  
 
6.2.4.1  This specification applies to all ICFLs and will be verified im mediately following the 
temperature test.  
 
6.2.4.2 The lamp must withstand a test potential of 240 V without breakdown, to be verified following 
the test method described in 8.3.5.  
 
 
6.2.5 Harmonic Distortion  
 
In the event that the total harmonic distortio n (THD) of the input current is stated on the product or its 
package, it must not be more than 10% greater than stated there, calculating as described in 8.3.6 with 
the ICFL cap upwards.  The information furnished on harmonic distortion must be quantitativ e. 
 
6.2.6 Impact  
 
An ICFL must be subjected to the tests described in 8.3.7. There must be no damage to the cover such 
as to render live parts or internal wiring accessible to contact, nor any damage to the mechanical 
protection that the cover affords to t he internal parts of the apparatus.  
 
In the case of ICFLs with metal coverings, there must be no breakdown as a result of the dielectric 
withstand test.  
 
 
6.2.7 Attenuation circuits  
 
An ICFL that can be used in attenuation circuits must be subjected to the  standard test specified in 
8.3.8.1 and must comply with the temperature limits specified in Table 3.  
 
Any device not intended for use in attenuation circuits must be marked as specified in 10.1.2  and must 
be subjected to the non -standard test specified i n 8.3.8.2. The protective envelope of the device being 
tested must not burn, ignite or char. There must be no damage to the cover such as to allow contact 
between live parts and the articulated test probe shown in figure 2. The device must pass the dielect ric 
voltage withstand test.  
 
6.2.8 Flame resistance  
 
Those parts made of insulating material and containing live parts and external parts made of insulating 
material which shield against electric shock must be subjected to the glow wire test and must meet the 
following requirements:  
 
a) The test model must be a complete lamp. It may be necessary to take a part of the lamp to run the 
test; however, care must be taken to ensure that the test conditions do not differ significantly 
from those occurring in norma l use.  
 
b) The temperature of the end of the glow wire must be 650°C.  
 NORMA SALVADOREÑA                                                                                         NSO 29.47.01:07

6.2.9  Heat shielding  
 
6.2.9.1  General considerations  
 
Ballasts for ICFLs other than those of the series reactor type must be heat protected in such a way that 
the input circuit opens when the ballast temperature exceeds the limits indicated in 6.2.9.2 and 6.2.9.3 
and in Table 4. The following rules apply to heat shields:  
 
a) The heat shield must be of the type that reconnects automatically or of the fuse type (not 
reconnectable) and must be des igned for the voltage and current conditions in which it will be 
operating.  
 
b) The heat shield must be located inside the ballast so that it is protected against knocks and is 
not easily accessed to prevent it from being voluntarily disconnected .

120 125 31 
115 120 53 
110 115 120 
 
 
During the heat shield test the encapsulating compound must not leak or ignite, and there must be no 
emission of flame or molten metal from inside the ballast casing or softening or ignition of plastic 
covers.  This is to be verified following the procedure described in 8.3.10.  
 
In the ca se of electronic ballasts which have an electronic circuit that limits the temperatures indicated 
in the sections mentioned above, there is no need to use the heat shield referred to in paragraphs a) and 
b). 
 
6.2.9.2  Breakdown conditions for electromagneti c and hybrid ballasts  
 
When the ballast is subjected to each of the breakdown conditions described in 8.3.10, the heat shield 
must be trigger ed to open the circuit before the temperature in the ballast casing reaches 110ºC, or else 
within the maximum time allowed once that temperature is reached, as specified in Table 4.  
 
The temperature of the power factor correction capacitor must not exceed 90ºC under any of the 
conditions described in 8.3.10 unless the capacitor is designed to operate at a higher temper ature, in 
which case the temperature ceiling shall be defined by its thermal class.  NORMA SALVADOREÑA                                                                                         NSO 29.47.01:07

The temperature at any point on the cover of an encapsulated ballast  or on the surface of a ballast with 
a bare nucleus and coil must not exceed 150°C.  
 
Points where the temperature exceeds 110°C when the heat shield opens the circuit must not exceed 
85°C when the heat shield cools down and recloses the circuit. Points where the temperature does not 
exceed 110°C when the heat shield opens the circuit must not exceed 100°C when the heat shield cools 
down and recloses the circuit.  
 
6.2.9.3  Breakdown conditions for electronic ballasts  
 
An electronic ballast must meet the requirements set out in 6.2.9.3.1, 6.2.9.3.2 and 6.2.9.3.3 when 
subjected to the tests described in 8.3.10.  
 
6.2.9.3.1  The temperature at any point on the cover of an electronic ballast (including ballasts 
without an automatically -reconnecting heat shield) must not exceed 150ºC.  
 
6.2.9.3.2  Points where the temperature exceeds 110ºC must satisfy the temperature versus time 
criterion specified in Table 4.  
 
6.2.9.3.3  In the case of a ballast with an integrated plug or with integrated connecting wires and plug, 
the temperature must not exceed 90ºC at any point on the cover.  
 
 
6.2.10  Heat resistance  
 
Conditioning of the equipment described in 8.3.11.2 must not cause softening of the material as 
determined by touching immediately after the test condition, nor must it contract, become twisted or 
undergo any other distortion as judged after cooling down to room temperatu re, such as to cause any of 
the following:  
 
a) reduction of the distance between uninsulated live parts with opposite polarity, uninsulated live

 Where:  
 FP is the power factor;

The input power, voltage and current are to be measured as indicated in 6.2.1.1 . The power factor 
delivered must be equal to or greater than the factor marked on the product.  
 
 
8.3.3  Leakage current

 e) type J or K thermocouples not larger than 0.205 mm2 (24 AWG) and not smalle r than 0.05 mm2 
(30 AWG),  
 
f) thermometer with 0.1°C or higher resolution.  
 
8.3.4.2  Procedure  
 
 An ICFL must be tested as follows:  
 
a) If the lamp can be fitted into the smaller test holder shown in figure 1, temperature 
measurements must be taken with the dev ice fitted into the test holder, which simulates the 
operation of a typical embedded socket. The device must be tested with the base upwards.  
 
b) A lamp which will not fit into the smaller test holder shown in figure 1 but can be fitted into the 
larger one mu st be tested in the latter. The device must be tested with the base upwards.  
c) Temperature measurements on any device exceeding the diameter of the test holder must be 
performed with the device mounted on a bench protected from air draughts. The device is to  be 
tested with the base upwards and the base downwards unless one of the orientations obviously 
produces less severe heating.  
 
d) Cylinders must be painted white on all sides.  
 
e) Each cylinder must be inserted in a rectangular test box. The cylinder is plac ed in the bottom of 
the test box. Three sides and the top must be 13 mm clear of the nearest part of the cylinder; the 
fourth side must be 76 mm clear of the nearest part of the cylinder . 
 
8.3.4.2.2  If an ICFL is not designed for operation with a completel y closed holder, the lower aperture 
in the test holder must be left open for the temperature test; otherwise, the device must be tested with a 
3 mm lens applied to the aperture in the test holder.  
 
8.3.4.2.3  During the test the ICFL must be powered at an i nput voltage and frequency as specified in 
8.1. Any ICFL that is designed for use in attenuation circuits must be subjected to the tests described in 
8.3.8.  
 
8.3.4.2.4  Thermocouples and a potentiometer or electronic instrument must be used whenever 
referen ce temperature measurements by thermocouples are required.  
 
8.3.4.2.5  Any joint linking a thermocouple and the bracket of an adjoining thermocouple must be held 
firmly in contact with the surface of the material whose temperature is being measured. In mos t cases 
adequate thermal contact is achieved by securing the thermocouple in place with cement. If a metal 
surface is involved, the thermocouple may have to be soldered to the metal.  
 
8.3.4.2.6  The temperature of a winding can be measured by thermocouple o r by change of resistance 
(comparing the resistance of the winding at the temperature at which it is to be measured with its 
resistance at a known temperature), using the formula specified in 8.3.4.2.8.  
 
8.3.4.2.7  The test must be pursued until constant t emperatures are obtained. A temperature is 
considered to be constant if:  
a) the test has gone on for at least 3 h, and  NORMA SALVADOREÑA                                                                                         NSO 29.47.01:07  
 
 16 
 
  
b) three successive readings, taken at 15 min intervals, are within 1°C of each other and have not 
increased.  
 
8.3.4.2.8 The temperature in a winding  must be calculated using the following formula:  
 
()()2 1 Tk TkRRT
CH
H +−+ =  
 Where:  
T1 is the temperature of the winding in degrees Celsius when R c is measured;  
TH is the temperature of the winding in degrees Celsius at the end of the test;  
RH is the re sistance of the winding at the end of the test, in ohms;  
RC is the resistance of the winding at the start of the test, in ohms;  
T2 is the ambient temperature at the end of the test, in degrees Celsius;  
K is 234.5 for a copper conductor or 225.0 for an EC g rade aluminium conductor. Values 
of the constant must be determined for other grades.  
 
8.3.4.2.9  Since it is generally necessary to deenergise the winding before measuring R, 
the value of R at the end of the test can be determined by taking several resista nce 
readings at short intervals, beginning  as rapidly as possible after shutoff. A curve of the 
resistance values can be plotted and extrapolated versus time to give the value of R at 
the end of the test.  
 
8.3.4.3  Results  
 
The temperature must not exceed the values indicated in Table 3.

8.4.5  Dielectric withstand voltage (Applied potential)  
 
The purpose of this test is to determine whether the insulation will withstand the design voltage 
without any breakdown when exposed to the electrical stresses produced by temporary voltage peaks.  
 
 
8.4.5.1  Instruments and equipment  
 
a) Source of application of alternating -current electric voltage; must:  
- have a nominal capacity of 500 VA at 60 Hz.  
- have the means to vary  the output voltage at the specified voltage values.  
- be equipped with tester shielding and an opening device  automatically triggered in the event of 
breakdown at 100 mA or higher.

c) Amperemeter to measure the test current with 5% precision or higher.  
d) Chronometer.  
e) Device to earth the sample at th e end of the test.  
 
 
8.4.5.2  Procedure  
 
8.4.5.2.1  An ICFL with accessible non -live metal parts must withstand a test voltage of 1240 V 
between all the live parts and all the accessible non -live metal parts, for 1 min without breakdown. The 
test must be per formed while the device is hot from normal operating.  
 
8.4.5.2.2  Voltage is to be raised from zero until the test voltage is reached then held at that voltage for 
1 min. The increase in voltage must be substantially uniform and as rapid as the accuracy of reading on 
the voltmeter will allow.  
 
8.4.5.2.3  The sensitivity of the test equipment must be such that when a calibrated resistance of 
120 000 Ω is connected to the output the equipment is considered to function acceptably well at any 
output voltage less than the specified test voltage, and it must indicate unacceptable functioning for 
any output voltage equal to or greater than the specified test voltage.  
 
8.4.5.3  Results  
 
The sample’s insulating elements are considered to pass the test if during applicat ion of the design 
voltage there are no disruptive discharges, perforations, flames or electric arcs and there is no drop in 
voltage or activation of breakdown indicators on the tester.

b) The metering equipment must be capable of measuring up to harmonic 32 with ± 5% accuracy.  
 
8.3.6.2  Procedure  
 
8.3.6.2.1  Because the voltage from the power source affects the magnitude of harmonic distortion, for 
purposes of measurement the input impedance must be 0.08 Ω. For some electronic sources it may be 
necessary to add resistance in order to achieve the specified input ìmpedance.  
 
8.3.6.2.2  The magnitu de of the different harmonics up to harmonic 33 must be recorded. The harmonic 
factor is the ratio between the harmonic content and the effective value of the fundamental frequency. 
The total harmonic distortion (THD) is to be calculated as follows :

8.3.7.2  Procedure  
 
8.3.7.2.1  An ICFL is dropped from a height of 0.91 m on to a hard wooden surface in the position that 
causes the most harm. The ICFL is dropped three tim es, in such a way that each time it strikes the 
surface in a different position. The assembly must rest on a concrete or  equally  solid  floor throughout 
the test.  
 
8.3.7.2.2  If an ICFL has a metal covering, it must next be subjected to the dielectric voltag e withstand 
test. There must be no damage to the cover such as to render live parts or internal wiring accessible to

source. The lamp must be operated at an ambient temperature of 25ºC with the base downwards. A 
single layer of gauze must be hung around the lamp to shut out the light source during the test. The 
gauze must be hung without pressi ng on to the device being tested, so that it serves as a flame indicator 
(presence of ash or burn holes), but it is not to be used as a mantle to trap heat. The lamp must be kept 
in operation for 7.5 h.  
 
8.3.8.2.3 Results  
 
The gauze must not burn, ignite or char. There must be no damage to the cover such as to allow contact 
between live parts and the articulated test probe shown in figure 2. The ICFL must pass the dielectric 
voltage withstand test.  
 
8.3.8.3 Half -wave rectified power input  
 
Any power source  of the kind specified in 8.3.6.1 must operate with a single properly -allocated 
semiconductor diode in series with the input phase conductor.  
 
8.3.8.4 Power input with an adjustable attenuator  
 
Any power source of the kind specified in 8.3.6.1 must operate  with an electrically adjustable 
attenuator connected in series. The attenuator must be of the adjustable phase -cut type with no 
component in its output circuits to attenuate the waveform, and it must produce an output waveform 
with a variable conduction a ngle similar to the one depicted in figure 3. The attenuator must be 
adjusted to cause maximum heating of the ICFL.

 8.3.9  Flame resistance  
 
Compliance with the non -flame -propagation requirem ents for ICFLs specified in 6.2.8 is to be verified 
by means of the flow wire test method described in Annex A.  
 
8.3.9.1 Procedure  
 
8.3.9.1.1  The test model is mounted on the carriage and pressed against the end of the glow wire with a 
force of 1 N, prefer ably at a distance of 15 mm or more from the upper edge and towards the centre of 
the surface being tested. Penetration of the specimen by the glow wire is limited mechanically to 7 
mm. 
 
8.3.9.1.2  If it is not possible to perform the test on a sample as de scribed above because the model is 
too small, the test must be performed on a separate sample made from the same material, with a 
surface area of 30 mm2 and the same thickness as the thinnest sample.  
 
8.3.9.1.3  The temperature of the end of the glow wire m ust be 650°C. The specimen must be removed 
from contact with the glow wire after 30 s.  
 
8.3.9.1.4  The temperature of the glow wire and the heating current must be constant for 1 min before 
the test commences. Care must be taken to ensure that the specimen is not influenced by radiated heat 
during this time. The temperature of the end of the glow wire is measured by means of a thin -wire 
thermocouple shielded as described in Annex A.  
 
8.3.9.2  Results  
 
Any flame or incandescence on the specimen must extinguish  itself within 30 seconds of removal of 
the glow wire, and any incandescence that falls must not ignite a piece of tissue paper placed 
horizontally 200 mm ±5 mm below the sample.  
 
8.3.10 Heat shielding  
The purpose of this test is to verify that ICFLs comp ly with the heat shielding requirements specified 
in 6.2.9.  
 
This test is applicable to all ICFLs.  
 
8.3.10.1 Instruments and equipment  
a) Type J or K thermocouples.  
b) Digital thermometer.  
c) Chronometer.  
d) Temperature testing chamber.  
 
8.3.10.2 Adjustin g the ICFL  
To perform the tests specified in 8.3.10.3.1, the ICFL being tested must be equipped with : 
a) terminals with access to allow the windings and components to be connected in short circuit;  
b) 5 thermocouples on the ballast cover.

 8.3.10.3.1 Breakdown conditions  
The ICFL’s heat shield must trigger the op ening of the input circuit before the temperature reaches 
110°C or within the limits indicated in point 6.2.9.  
 
The ICFL must be energised up to the nominal operating conditions  (voltage and frequency in the 
temperature test chamber) and the conditions specified in point 6.2.9 applied, until thermal equilibrium 
is reached under normal conditions; then it will be subjected, one by one, to each of the breakdown 
conditions described  hereafter. Each one of these is to be treated as a complete test.  
a) Connect in short -circuit the last two layers of a coil with inter -layer insulation (or 20% of the turns 
in a coil with a different type of winding) of the primary coil.  
b) Connect in sho rt-circuit the last two layers of a coil with inter -layer insulation (or 20% of the turns 
in a coil with a different type of winding) of the secondary coil.  
c) Operate in abnormal condition s. This test need not be performed when the abnormal temperature in  
the incremental test does not exceed 110ºC.  
d) Connect, in short -circuit or in open circuit, any electrolytic capacitor or semiconductor element in 
the circuit that is capable of delivering 50 W or more to an external resistor for 1 min.  
e) Connect in sho rt-circuit the power factor correction capacitor, provided that this does not produce a 
short circuit in the ballast’s primary winding.  
 
During this test, a delayed -action 20A fuse is connected in such a way that the fuse will not open 
before 12 seconds wh en 40A is conducted..  
 
The time -lapse between the moment at which the surface temperature of the lamp body housing the 
ballast surpasses 110oC and the moment at which the heat shield comes into operation or maximum 
temperature is reached must comply with t he specifications in point 6.2.9.

A.3 DESCRIPTION OF TEST CONSIDERATIONS AND SELECTION OF TEST 
SPECIMENS  
 
If possible, the specimen must be a finished product. The test specimen must be selected in such a way 
that the test conditions do not differ significantly from those arising in normal use as regards shape, 
ventilation, the effect of thermal stress and the po ssibility of flames occurring or burning or 
incandescent particles falling in the vicinity of the test specimen.  
 
If the test is not performed on a finished product, or if the relevant product standard specifies 
otherwise, one of the following options must  be followed in performing the test:  
 
a) A piece containing the part for examination is cut from the finished product; or  
b) An opening is cut in the finished product to afford access to the glow -wire; or  
 
c) The part being examined is removed completely and teste d separately.  
 
A small opening can affect the results by allowing the surrounding area to ignite, reducing the 
temperature of the glow wire or restricting the availability of oxygen, while a very large opening will 
admit more oxygen than is normally availa ble. 
 
The test is not valid if in the course of it  any part of the equipment containing the test specimen is 
ignited by additional heat from the glow wire and affects the thermal conditions in the test specimen.  
 
The test is performed to ensure that under  certain given conditions the glow wire will not cause parts to 
ignite, and that if a part does go on fire it will do so for a limited time under those conditions, and the 
fire will not be spread by flames or burning or incandescent particles from the test  specimen.  
 
If the test specimen emits flames while the glow wire is being applied, the risk of fire that entails may 
make it necessary to perform additional tests using other ignition sources such as a needle flame, 
applied to those parts reached by the f lames from the specimen.  
 
The glow wire test must not be used on small parts, for which it may be necessary to resort to other 
procedures such as the needle -flame test.  
 
A.4 DESCRIPTION OF TEST APPARATUS  
 
A description of the test apparatus can be found in  Annex B.  
 
To assess the possibility of flame propagation, due for example to burning or incandescent particles 
falling from the test specimen, a layer of the material specified in Annex B, or of the kind of material 
or components normally surrounding or b elow the test specimen, are placed beneath it. The distances NORMA SALVADOREÑA                                                                                         NSO 29.47.01:07

 between the test specimen and the layer of specified material representing the surrounding material or 
components must be the same as when the specimen is mounted on the electrical product.  
 
If the test specimen is a complete self -supported device, it is placed in the normal operating position 
above the layer of material specified in Annex B, which is spread to at least 100 mm in all directions 
beyond the base of the device.  
 
If the specimen is a complete wall -mounted device, it is fixed in its normal operating position, 200 mm 
± 5 mm above the layer of material specified in Annex B.  
 
A.5 TEST TEMPERATURES  
 
The test temperature must be selected from among those listed in table 1 below.  
 
 
 
Table 1.  Test temperatures

Other temperatures may be used if required by the relevant product standard in Table 2 – Guide for the 
glow wire test.  
 
The appropriate test temperatur e must be selected by estimating the risk of failure due to an inadequate 
response to abnormal heat, to flame ignition and propagation or to the expected consequences of a 
failure.

DESCRIPTION OF TEST APPARATUS  
 
B.1 GLOW WIRE  
 
The glow wire is a 4 mm diameter nickel/chrome (80/20) wire. The wire is bent back at the end as 
detailed in figure 1.

The glow wire is heated by a simple electrical circuit as shown in figure 2. There should be no 
feedback mechanism or circuit to maintain temperature.  
 
 
 
Figur e 2. Test Circuit  
 
In view of the strong currents involved, it is essential that the electrical connections for the glow wire 
be capable of conducting the current without affecting the performance or stability of the circuit 
throughout the test time.  
 
Note  1. The current typically necessary to heat the end to a temperature of 960ºC ranges from 120A to 150A  
 
The test apparatus must be designed so that the glow wire lies on a horizontal plane and applies a force 
of 1.0 N ± 0.2 N to the test specimen throughou t the test. The force must remain at that level when the 
flow wire is moved horizontally towards the specimen or vice versa. Penetration into or through the 
specimen by the end of the glow wire must be limited to 7 mm ± 0,5 mm.  
 
The test apparatus must be designed so that any burning or incandescent particles that fall from the test 
specimen can fall on the layer specified in B.3.  
 
Figures 3 a) and 3 b) show two typical examples of the test apparatus.  Fuente de

B.2 TEMPERATURE MEASURING SYSTEM  
 
The temperature at th e end of the glow wire must be measured by a thin wire thermocouple with metal 
covering and mineral insulation and an insulated joint. It must have a nominal outer diameter of 1.0 
mm or 0.5 mm and wires, for example of NiCr and NiAl (K type), suitable for continuous operation at 
temperatures up to 960ºC, with the soldered point located inside the cover as close as possible to the 
end. The cover must be made of a tough metal suitable for continuous operation at a temperature of at 
least 1050ºC. In case of do ubt, the 0.5 mm thermocouple should be used.  
 
Notes.  
 
3) A cover made of a heat -resistant alloy with a nickel base must also meet the above requirements.  
 
4) It is intended to delete the reference to 0.5 mm thermocouples in a future review of this standard . 
 
The glow wire, with the thermocouple, is shown in figure 1.  NORMA SALVADOREÑA                                                                                         NSO 29.47.01:07

The thermocouple is inserted in a hole drilled in the back of the end of the glow wire and is kept in 
adjustment as shown in figure 1, detail Z. Thermal contact must be maintained between the point of the 
thermocouple and the end of the drilled hole. Care must be taken to ensure that the thermocouple can 
keep up with the changes in the dimension of the end of the glow wire produced by heating.  
 
Any commercial digital thermometer may be used to measure thermal tensions.  
 
Note 5. Other instruments may be used to measure the temperature, but in case of dispute the thermocouple method must be 
used. 
 
 
B.3 SPECIFIED LAYER  
 
To assess the possibility of fire propagation, for example by incandescent or b urning particles falling 
from the test specimen, a specified layer must be placed beneath the test specimen.  
 
Unless otherwise specified, a single layer of tissue paper is to be placed on top of and in direct contact 
with the upper surface of a smooth, fla t wooden board at least 10 mm thick, placed at a distance of 
200±5 mm below the place where the glow wire is to be applied to the test specimen.  See figures 3a 
and 3b.  
 
Tissue paper is a light, soft but strong wrapping paper with a weight between 12 g/m2 and 30 g/m2. 
 
The tissue paper may be replaced.  
 
B.4 TEST CHAMBER  
 
The apparatus must be operated in draught -free conditions. This can be achieved by using a chamber 
having a volume of at least 0.5 m3 which permits observation of the test specimen. The vol ume of the 
chamber must be such that the result is not affected by oxygen exhaustion during the test. The test 
specimen must be mounted at least 100 mm clear of any surface in the chamber. The chamber must be 
ventilated after each test to safely remove the  air containing the degradation products. The ambient 
light falling on the test specimen, not counting the glow wire, must not exceed 20 lx, and the 
background material must be dark. The chamber shall be considered sufficiently dark if the luxmeter is 
placed facing the back of the chamber in place of the test specimen and the level is less than 20 lx.  
 
Note 6. For the purpose of adjusting existing test chambers, the 0.5 m3 requirement must be in place two years after the 
promulgation of this standard comes into force.

 ANNEX C  
VERIFYING TEST APPARATUSES  
 
C.1 VERIFYING THE END OF THE GLOW WIRE  
 
Before each test series the end of the glow wire must be inspected by measuring and recording the 
dimension “A” as shown in figure 1, detail Z. This is to be compare d with subsequent tests, and when 
this dimension falls to 90% of the original reading, then the glow wire must be replaced.  
 
Upon completion of each test, the end must be cleaned, if necessary, to remove any residue of previous 
test material, for example u sing a wire brush; then the end of the glow wire must be inspected to ensure 
that there is no cracking.  
 
C.2 VERIFYING THE TEMPERATURE MEASUREMENT SYSTEM  
 
C.2.1  The continuity of proper performance and calibration of the temperature measurement system 
specified in B.2 must be checked periodically.  
 
C.2.2  The temperature may be at a given point in the glow wire using a silver sheet of at least 92.5% 
purity and a thickness of 0.06 mm, placed on the upper surface of the glow wire end. The glow wire is 
to be he ated at a suitably slow rate; when the sheet begins to melt the thermometer should read 960 ºC 
± 15 ºC. The glow wire should be cleaned of any silver residue immediately after this verification 
process, while it is still hot, to reduce the chances of alloy ing. 
 
C.3 CONDITIONING  
 
Before the test, the wooden board and the tissue paper must be stored for 24 h in an atmosphere where 
the temperature is between  15ºC and 35ºC and the relative humidity between 45% and 75%.  
 
 
The design proposed here is to ensure that heat losses are insignificant.  
Tolerances and dimensions are not shown as this is merely an example.

 ANNEX D  
COMMON TEST PROCEDURE  
 
Warning:  
Precautions must be taken to protect t he health of the personnel performing the tests, against:  
• Risks of explosion, fire or flame;  
• Risk of collision;  
• Inhalation of smoke and/or toxic products;  
• Toxic residues  
 
D.1 The test specimen must be mounted and secured in such a way that:  
 
a) there are no s ignificant heat losses due to the means of securing or support;  
b) the flat part of the surface is vertical;  
c) the end of the glow wire is applied to the centre of the flat part of the surface.  
 
D.2 The glow wire is to be heated to the specified temperature, w hich is measured using a 
calibrated temperature measurement system; before the end of the glow wire is placed in contact with 
the test specimen, care must be taken to ensure that:  
 
a) its temperature is constant within 5 K for at least 60 s;  
b) the heat radiatio n does not influence the specimen during this time; an adequate distance must 
be maintained, for instance at least 0.5 cm, or a suitable shield must be used;  
c) there must be no subsequent adjustment of the heating current or voltage until the test is 
conclud ed. 
 
D.3 The end of the glow wire is brought slowly into contact with the test specimen for 30 s ± 1s. An 
approach and withdrawal rate of 10 mm/s to 25 mm/s has been found to be satisfactory. However, the 
rate of approach must be reduced almost to zero at contact so that the impact force does not exceed 1.0 
N ± 0.2 N. In cases where the material melts at a distance from the glow wire, the glow wire must not 
be allowed to come into contact with the test specimen. At the end of the application time, the glow 
wire and the test specimen must be separated slowly, avoiding any additional heating of the test 
specimen and any air movement that might affect the result of the test. Penetration of the glow wire 
inside and through the test specimen must be limited to 7 mm ± 0,5 mm.
