2.2 Special conditions for safe use
2.2.1 Intrinsic Safety (Ex protection)
IRwin is certified intrinsically safe to prevent ignition of flammable atmospheres.
IRwin holds an ATEX certificate for EU and corresponding certificates for several otherregions.
For details of rating, see EX certification (intrinsic safety) [} 23].
The "X" after the respective type certificate number relates to the following special
conditions for safe use:
Applied standards are listed in the EU declaration of comformity "Declarations ofconformity [} 106]".
The only device allowed to be connected to the charging socket on any of the models• IRwin SX• IRwin SXT• IRwin SXG• IRwin SXGT
is the Ex Certified IRwin Charging adapter (PN 580-604).
The charger or car adapter is subsequently connected to the inlet of the Ex Certified
IRwin Charging Adapter.
This means that the charger for IRwin S must, under no circumstances, be connected
directly to the charging socket on any of IRwin models SX, SXT, SXG, and SXGT. See
also Charging the battery [} 37].
IRwin SXnn is certified as intrinsically safe at an ambient temperature of -20 - +50°C.

Safety | 2

IRwin SXnn is certified for use in Gas groups IIA, IIB and IIC (excluding Acetylene)
and in Zones 0, 1 and 2 "Declarations of conformity [} 106]".

WARNING
IRwin must not be used in applications where there is risk for exposure
to acetylene.
► Avoid also storage in potential acetylene atmospheres.
► If used in Acetylene atmospheres, Acetylides, prone to ignition by friction impact,
can potentially form on the bronze filters in the reference inlet and exhaust.
The external surface of the enclosure is therefore slightly conductive to prevent
electrostatic charging and sparks. Labels, ink or paint added for marking purposesmust not be larger than 400 mm2. Adding larger labels invalidates the Ex certifications
due to risk for electrostatic charging and discharging.

• Hand probe is used for checking features on or in buildings. Hand probe also
constitutes the handle for carpet probe and bell probe.
• Bar Hole probe is used to sample air from drilled holes. Push into hole and tighten
screw to expand rubber before connecting sample line.
• Optional Hand Probe Flexible Extension can be connected to the hand probe or
rod for easier access.
• Swan Neck Probe is used on uneven surfaces and in bushes etc.
• Flexi Bell is used for simple survey including meters and piping. The bell adapts topipe geometry.
INFICON single-cell

IRwin methane leak detector uses the unique INFICON single-cell wide range

wide range

technology for detecting all concentrations from 1 ppm to 100 Vol% methane. This

technology (patenttechnology is very sensitive to the ethane content of natural gas. Therefore, large

pending)deviations can occur at higher methane concentrations if the ethane concentration is
not compensated for. The instrument has built-in routines for ethane compensation.
The actual ethane concentration can be determined using the IR Ethane Analysis
function. This can be used to automatically set the compensation concentration. If

3 | Description

INFICONpreferred you can instead set the ethane content manually. The safety certified modes
Ex and Ex Tox are not affected by this phenomenon. See "IR Ethane Analysis andcompensation [} 77]".
IRwin SXG and SXGT models also have GC Ethane Analysis capability for
distinguishing between Natural gas (NG), liquid petroleum gas (LPG) and swamp gas
by determining the presence of methane, ethane and propane in the sampled gas.
The GC Ethane Analysis function is not affecting the ethane compensation.

5.2.8 PPM Adjustment Factor
The PPM Adjustment Factor can be used to slightly overestimate low natural gas
concentrations. This can be handy if bump test requirements require an indication ofat least 10 ppm instead of the specified tolerance of +5/-2 ppm.
The selected value (1.0 to 2.0) will be multiplied with the calibrated reading.
Setting this factor to e.g., 1.4 will make IRwin display a 10 ppm reading as
1.4 x 10 = 14 ppm.
This adjustment affects values up to 10 ppm and turns into a minor offset above 10
ppm.

Explosion hazard
Irwin S is not certified for use in explosive atmospheres and is also not suitable for
estimating fire potential (LEL level).

Alarm indications:
Gas alarms are usually separated into three levels of severity:
Priority

Alarm

Table 17: Set limits and alarm levels

The detector will beep and the status LED and the display will be red if the measured
gas concentration exceeds a set alarm level (below threshold for O2 alarms AL1 andAL2).
Faster flashing or beeping will indicate more severe conditions. See table above.
The oxygen alarm differs from the other in that the main risk (asphyxiation) is
associated with low oxygen. The alarms AL1 and AL2 for oxygen warns when theoxygen concentration goes below the respective alarm level. AL3 for oxygen is
activated when oxygen concentration exceeds AL3.
The % unit in the settings menu means % of LEL for Ex and Ex Tox operation modes
and volume % for all other modes. In the operating modes "Universal", "Above
Ground", "Plants" and "House" you can also set a PPM level alarm to help whensurveying for leaks.
The acoustic signal and the status LED are the primary alarm signals of the operating
modes "Ex" and "Ex Tox".
• All alarms are latching and must be confirmed manually even if the alarm
conditions that lead to the alarm are no longer existing. Alarms are confirmed bypressing the upper right key, next to the check mark.
The alarm will come on again if the alarm condition is still valid.
• You can temporarily mute the alarm by pressing the lower left key (). Themuting will turn off automatically after 15 minutes.
You can unmute the alarm manually by pressing the lower left key again.
• Muting will also turn off if a higher alarm is triggered.

IRwin can be configured in three main modes: DVGW, Universal and Universal+.
DVGW mode is adapted to German, Dutch and Polish work procedures with specifictest modes for different applications.
Universal and Universal+ modes combines most of the different modes of the DVGW
mode into one single, full range, auto-ranging mode.
GC Ethane Analysis, Ex and ExTox modes are, however still separate. Universal+
mode is similar to Universal mode but the main measuring display is adapted to the
UK EM72 work procedure.

5.3.5 Operating mode "GC Ethane Analysis"
This mode is intended for determining if a gas sample is natural gas (NG) or liquefied
petroleum gas (LPG), by identifying the methane, ethane and propane content.
Natural gas (NG) typically contain at least 0.5 vol% of ethane in addition to a highconcentration of methane.
Liquefied petroleum gas (LPG) typically contain propane or butane or a mixture of thetwo.
These differences are the basis for identifying gas type from an hydrocarbon analysis.
While significant ethane content (>0.5 Vol%) in a methane rich mixture is a certain
indication of natural gas, it is not entirely safe to say that no indication of ethane in amethane rich mixture is a certain indication of swamp gas.
Some natural gas contains no or only traces of ethane.
This can be due to several reasons, for example:• The gas source is solely or partly liquefied natural gas (LNG) which sometime hasvery low ethane content.
• The gas source is solely or partly biogas.
• The natural gas source has very low ethane content.

The following procedure is highly recommended on site to strengthen the evidence
that a gas sample is indeed natural gas:
• Check that ambient temperature is within range for GC Ethane Analysis: 0 – 50°C
(32-122°F)• Perform a GC Ethane Analysis Function test to check that the GC Ethane Analysis
can detect ethane down to 0.5 Vol% in the gas sample. Gas used see

INFICON• Make a GC Ethane Analysis on the gas to be identified and compare the resulting
curve to that obtained from the natural gas sample. Three consecutive tests withsame result should serve as a clear result.
• If any doubt on this result remains perform a final function test to assure that theunit was working properly during testing.
If the ethane content in the natural gas is below 0.5 Vol% the GC Ethane Analysis
cannot be used. The GC must also give a clear indication of ethane to serve as anindicator of natural gas. A clear indication is a ticked ethane box on the screen.
IRwin GC is sensitive enough to detect 0.5 % ethane in methane.
The operator is fully responsible for evaluating the logic and likelihood of thecorrectness of the result being presented by IRwin, based on the ethane content in thetested gas, the maintenance and functionality of IRwin Methane Leak Detector andother circumstances related to the issue.

Overloading the GC column with high gas concentrations will makeanalysis slow and possible non-functional

Measuring of high gas concentrations of H2S or CO reduces sensor lifetime.
Frequent measuring of high gas concentrations will reduce the life time of the sensors
for the detection of toxic gases.
Set Time Weighted

The leak detector has a TWA-Function (Time Weighted Average Function) with which

Average (TWA)

alarms can be given according to LTEL (Long Term Exposure Limit) or STEL (ShortTerm Exposure Limit). The LTEL value and the STEL value correspond to the
maximum dose of a substance to which a person should be exposed over a defined
period.
• STEL is the weighted average value over 15 minutes (for the respective toxic gas).
• LTEL is the weighted average value over 8 hours (for the respective toxic gas).
To set the Alarm Level for LTEL and STEL, see "Set limits and alarm levels [} 48]".

5.3.11 IR Ethane Analysis and compensation

Why an IR EthaneThis function is mainly used to distinguish between natural gas and swamp gas from

Analysis?

underground biological decay. Natural gas contains varying concentrations of ethane
while swamp gas does not.
Such analysis is traditionally made with a gas chromatograph. With IRwin the same
analysis with similar sensitivity is performed much faster. Instead of the typical 5 to 10
minutes a gas chromatograph requires for an analysis IRwin only needs a few
seconds.
The second purpose of the IR Ethane Analysis is to establish the ethane concentration
for compensation at high methane levels.
The IR Ethane Analysis can be made from below 1 to 8 Vol% ethane in the naturalgas. The resolution is 0.1% and the accuracy better than 1 Vol%.

INFICON single-cell

IRwin methane leak detector employs the unique INFICON single-cell wide range

wide range

technology to detect all concentrations from 1 ppm to 100 Vol% methane. This

technology (patent-

technology is very sensitive to the ethane content in the natural gas. Therefore, large

pending)deviations can occur at higher gas concentrations if the ethane concentration is notcompensated for.
The leak detector has a built-in routine for ethane compensation. The ethane content
can be entered manually, if known. A more practical way is to use the IR Ethane
Analysis function to measure the ethane content and automatically set thecompensation concentration. The safety certified modes Ex and Ex Tox are notaffected by this phenomenon.
IRwin SXG and SXGT models also have GC Ethane Analysis capability for
distinguishing between Natural gas (NG), liquid petroleum gas (LPG) and swamp gas
by determining the presence of methane, ethane and propane in the sampled gas.
The GC Ethane Analysis function is not affecting the ethane compensation.

5.3.11.3 Performing IR Ethane Analysis after automatic reminder
You need a methane concentration in the range of 5 to 15 Vol% to perform the IR
Ethane Analysis. The compensation is only needed for high gas concentrations and istherefore only needed when you have found a significant leak.
You should connect the Bell probe before performing the IR Ethane Analysis.

ð If reminder is activated a window will appear showing the current ethane
concentration setting. The leak detector asks if you want to keep the current
value or a make a new analysis.

2

Select "New” and press the bell firmly down onto the place where you found thegas.
ð A number between 0 and 100 appears on the display.

3

If the value is smaller than 20, push the probe harder onto the surface or look
for a place with higher methane concentration. If the value is higher that 80 you
should move the bell away from the leak to find a spot with lower concentration.

ð

Try to make the signal stabilize at a value between 20 and 80. When
succeeding, the detector will need another 2-3 seconds to calculate the ethane
concentration. The result is displayed as % C2H6.

ð

Press check mark to continue. IRwin will ask if you want to "Save Ethane
Concentration for Compensation".

ð

Select "No" if analysis was made for confirming natural gas or "Yes" to use forcompensation. If selecting "Yes" the value is saved as ethane concentration andshown in the C2H6 field.
See Operating mode “Bar Hole” [} 59].

ðAn ethane concentration value of 1 % or higher is a safe indication of naturalgas. A value between 0.4 and 1 % is a probable indication of natural gas.

If the measured ethane values are between 0 and 2% it is recommended that you
repeat the measurement at least 3 times on the same position to check the result is
consistent.

5.3.12 Calibration (adjustment)
Calibration is interpreted differently in different countries andapplications. Throughout this document we therefore use the following
definitions:
Function Test: Exposing to given gas(es) checking if accuracy of a certain
measurement is within specified accuracy and to judge weather calibration adjustment
is needed.
Calibration: Exposing to given gas(es) and, if required, automatically adjusting thedetector to display the given concentration within specified accuracy.
The built-in calibration routines guide you through the adjustment of the leak detector
sensitivity to the various test gases. You can set calibration intervals for the different
adjustments and will then get a reminder when calibration is due ("Adjust calibration
reminder").
The description below cover all possible modes. Only part of them are activateddepending on he actual setting of the detector.
Allow IRwin to warm up for 1 hour before calibrating for best accuracy.

The calibration intervals recommended for the operating modes Ex and Ex Tox are
based on the TÜV certificates for these operating modes. For the other modes thesetime intervals are chosen to give you the best performance. In any case you should
use the results of the various function tests to judge whether a calibration is needed. If
you want to perform more than one calibration procedure at a given time you should
run them in the following sequence for best performance.
1. Above Ground if DVGW mode is enabled
2. Universal (low range) if Universal or Universal+ mode is enabled
3. Ex CH4 (IRwin SX, SXT, SXG and SXGT only)
4. Tox (IRwin SXT and SXGT only)
5. Bar Hole CH4 or Universal (high range) if Universal or Universal+ mode is enabled
6. Bar Hole CO2 or Universal (20% CO2) if Universal or Universal+ mode is enabled

Recommended calibration check intervals• Above Ground CH4 - weeklyWith this calibration you calibrate the higher range (Vol%) of the modes House
and Bar Hole at the same time.

INFICON• Universal (low range) - weekly
For calibration adjustment of Universal (low range) you need one, two or threegases as specified in section “Concentration of calibration and test gases”, see
Concentration of calibration and test gases [} 35].
• Tox - weekly
For calibration in Ex Tox mode you need Tox mix.
The CO2 calibration of other modes is not affected. CH4 of the operation mode Ex
is also calibrated during the Ex Tox calibration. However, for best performance, it
is recommended to perform the Ex calibration after the Ex Tox calibration.
• Ex CH4 - weekly
For calibration in Ex mode you need the following gas concentrations:
2.2% CH4.
• Bar Hole CO2 / Universal (20.0% CO2) - monthly
For calibration of the CO2 measurement of Bar Hole you need the following gas
concentrations: 20% CO2.
This calibration does not influence the toxic CO2 calibration (ppm) in the Ex Tox
calibration routine.

• Bar Hole CH4 / Universal (high range) - monthly
For calibration of the CH4 measurement of Bar Hole you need the following gas
concentrations:
2.2% CH4, 100% CH4.
Beside the calibrations of the application mode “Bar Hole” the application modes“Gas Purity” and “Confined Space” will be calibrated in the higher measurement
range (Vol%), too.
• GC Ethane Analysis (normally not required)
Calibration of the GC is normally done after service to the GC but can also bedone if the GC graphs look abnormal. This can be the case if the GC sensor has
been subjected to high gas concentrations.
GC calibration is done using 50 %LEL CH4 (2.2 or 2.5 Vol% depending on LEL
setting) and is only accessible if logged in as advanced user.
For full functionality you must perform a GC Function Test directly after performing
a GC calibration.

WARNING
Explosion, asphyxiation, toxic risk
Incorrect calibration leads to incorrect measurement results. Thus you are not properly
warned against any possibly dangerous gas concentrations.
► Calibrate the leak detector only when you have been properly trained.
► Calibrate the detector in well ventilated rooms or outdoors.

The methane calibration is possible with gas mixtures in synthetic air only.
The natural background of CO2 (typically 400 ppm) in ambient air will offset thecalibration.
Fresh air exposure should, however, always be by ambient air.

After the leak detector has been calibrated with 100% methane it shows a few ppm
increase in the measured value for a few minutes. This is a normal behavior of theleak detector and due to gas residues inside the leak detector.

Operation | 5• The gas flow delivered by the calibration station must be higher than the flow
aspired by the leak detector. Set the gas flow to at least 80 l/h.
• The gas must be delivered at ambient pressure (i.e., do not push gas into the leakdetector). The normal way to accomplish this is to create an open connection
between gas container and detector inlet so that the excess calibration gas isvented to the ambient. This exhaust should be placed outside the test room,
preferably outdoors.

For optimum performance adjust the concentrations of the calibration gases set in theleak detector to the actual composition of your calibration gases.
For optimum performance of your leak detector you should use the proposed
calibration gases. The exact concentrations of the gas delivered often deviates slightly
from these values due to tolerance factors etc. The exact value is typically stated on
the analysis certificate of the respective gas. You should therefore adjust theconcentrations of the calibration gases set in the detector to match the actual
composition of your calibration gases, see "Concentration of calibration and test gases[} 35]".

5.4 Performing function tests
Correct readings only if settings are correct.
If the leak detector does not work correctly, it may not show every leak.
► Test the leak detector regularly as recommended.

Function tests are available for all tasks of the detector.
Some of these tests are typically called "bump tests".
Use the Function tests to test the status and accuracy of the leak detector. The leakdetector will guide you through the test procedures and tell you when operator actions
are needed.
Passing the function test means that specific detector function performs as specified.
No adjustment (in this context called Calibration) is needed for that specific function.
Repeated failure of a function test is an indication that the detector needs calibration
for that particular function. See "Calibration (adjustment) [} 81]".
Once you have set the function test intervals, the leak detector will remind you to
perform the respective Function test, see "Setting the Function Test Interval [} 51]".
Recommended• Before starting work / bump testing

Function test

For leak surveys we recommend performing a 10 ppm bump test before startingintervals (based on

survey. This is required by German DVGW and local regulations in several otherIRwin model)

countries. If your survey limit is higher or you are using IRwin for another purpose
it is possible to use either 500 ppm or 2.5 Vol% instead. Select desired gas byadjusting the function test gas. See, "Universal Fnc Test conc / AbG Fnc Test
conc [} 50]".

Function tests are optimized for factory default concentrations. Using otherconcentrations, even if within the adjustable calibration or function test concentration
range, can make the automatic function test interpretation invalid.
If you fail function test and you are using non-standard gases we recommend that you
test the instrument by simply exposing the respective mode for the test gas andobserve the reading. This way you can still verify the function but the last passed
function test will not be logged if automatic interpretation failed.

Do not use this option without cause. You risk losing settings and the bias of theoxygen sensor on SXT and SXGT models. This leads to a prolonged warm up at next
power on. It can take up to 12 hours to stabilize the oxygen sensor if sensor bias islost form more than a few minutes. If you need to do a hardware switch off you should
restart the leak detector immediately, If the leak detector malfunctions again you willneed to contact INFICON service.

6 Maintenance
The gas inlet of the instrument, as well as the probe system include various filters.
These must be replaced at intervals specified in the maintenance plan. If the leakdetector is used in dirty environments, more frequent replacements may benecessary.

The internal sample inlet filter can become clogged.
Running the leak detector with no probe connected can make the internal filters
clogged. This can cause need for service.
