 SAFETY REQUIREMENTS FOR CORD EXTENSION SETS  
230 V/13 A  
 
 
1.0 SCOPE AND OBJECT  
 
 This Saudi standard applies to cord extension sets (fused plug, 3 core flexible cables 
and portable socket -outlets with supplementary over current protection) for 
household, commercial and light industrial purposes, with particular reference t o 
safety in normal use. Cord extension sets are suitable for the connection of 
appliances, sound -vision equipment, luminaires, etc. in a.c. circuits only, operating 
at rated voltage of  230 V r.m.s. at 60 Hz having rated current of 13A, using plug 
accordan ce with  SASO 2203 .   
13A Fused plugs of cord extension sets having insulating sleeves on line and neutral 
pins. The p lug may be rewirable or non -rewirable complete  with 3 core flexible 
cable with nominal cross -sectional area of 1.5 mm2 and 2.5 mm2. The plugs shall  
incorporate a fuse complying with BS 1362.  
 This standard does not applies to 13 A plugs which have the metallic earth pin 
replaced with a similarly dimensioned protrusion made of insulating material 
designated as an insulated shutter opening d evice (ISOD) designed to operate the 
shutter mechanism of a socket -outlet.  
 Plugs containing switches and devices other than indicator lamps are outside the 
scope of this standard.  
                  13 A shuttered portable socket -outlets of cord extension sets may be in single or 
multiple arrangements with or without switches which can be powered from 13A 
fixed socket outlet system complies SASO 2203.  
 Portable socket -outlets containing devices other than supplementary over current 
protection, switches, USB  charging outlets, surge protective devices and indicator 
lamps are outside the scope of this standard.  
 
 Fixed socket -outlets are outside the scope of this standard.  
 
 This standard supersedes SASO 2815:2010  with respect to its specific rating and 
test requirements according to the Kingdom of Saudi Arabia  requirements. 
Reference standard tests are performed with this standard specified value e.g. rated 
voltage is 230V r.m.s. at 60Hz.  
 
 Manufacturers shall pro duce the cord extension sets consists at least with fused plug, 
flexible cable and portable socket -outlet with supplementary over current 
protection. Supplying of rewirable  portable  socket -outlet alone to end -user is not 
allowed .

7.1 Each cord extension set  shall have the following information clearly and durably 
marked on it, in Arabic or English.  
 a. Country of origin  
 b. Manufacturer’s or responsible vendor’s name, trade mark or identification mark.  
                  NOTE:  This marking for cord extensio n set is necessary only if the manufacturer of the cord 
extension set is different to the manufacturer of the portable socket -outlet. The marking of the 
name, trade mark or identification mark of the manufacturer or responsible vendor may for 
example be ap plied on a sleeve or label provided around the cord.  
 c. Type reference which may be a catalogue number.  
                      NOTE:  For a cord extension set, the type reference, which may be a catalogue number, may be 
placed on the smallest packaging uni t. 
 d. Rated current in amperes.  
                  e. Rated voltage in volts.  
 f. Identification of each of the live, the neutral and the earthed pole.  
 g. For fused plugs, the word “Fuse” or “Fused” or symbol.  
                  h. Power in watts.  
                  The marking of power shall be completed by the word MAX.                                                           
The power is calculated using nominal supply voltage in volts and a power   .       
factor cos φ = 1.  (examples: MAX 2990 W or 2990 W MAX)  
                  The maximum admissible power marking shall not be hidden by any inserted plug.  
 i. Cord extension sets with IP 20 or IP 41 shall be marked clearly as indoor use only.  SASO STANDARD                                                        SASO/FDS/  2815 :2012

  j. If symbols are used they shall be as follows:  
- Amperes  : A 
- Volts  : V 
- Fuse  :  
- Neutral or live  : N or L  
- Earth  : E or    
- Fused live  : L 
- Watt  : W 
- Indoor use only  :       
  Note 1: For rough use plugs and portable socket -outlets, the reference Standard’s number (SASO 
or BS) shall be followed by “/A”.  
Note 2: where the declared IP classification is higher than IP20 then the IP classification shall be 
marked (IPXX). The IP of cord extension set is the same as lowest protection degree of the plug 
and the portable socket outlet.  
 
7.3 Conformity shall be checked by the inspection and tests described in the clause 7 of 
the reference standard BS 1363 -2.

 Annex A  : 
 
Safety -related routine tests for factory -wired portable accessories  
(protection against electric shock and correct polarity)  
 
 
A.1 General Remarks  
                  All factory -wired plugs and portable socket -outlets shall be subjected to tests 
specified in clauses A.2, A.3 and A.4.  
The test equipment or manufacturing systems shall be such that failed products are 
either made unfit for use or separated from satisfactory products in such a way that 
they cannot be released for sale.  
NOTE:  “Unfit for use” means  that the accessory is tr eated in such a way that it cannot fulfil the 
intended function. It is, however, accepted that repairable products (by a reliable system) may be 
repaired and re -tested.  
It shall be possible by process or manufacturing system to identity that accessories 
released for sale have been subjected to all the appropriate tests.  
The manufacturers shall maintain records of the tests carried out which show  
- the type of product;  
- the date of test;  
- the place of manufacture (if manufacture in more than one place)  
- the quan tity tested;  
- the number of failures and actions taken, i.e. destroyed/repaired.  
The test equipment shall be checked before and after each period of use and for 
periods of continuous use, at least once every 24 h. During these checks are 
equipment shall sho w that it indicates faults when known faulty products are 
inserted or simulated  faults are applied.  
Products manufactured prior to a check shall only be released for sale if the check 
is found satisfactory.  
Test equipment shall be verified (calibrated) at  least once a year. Records shall be 
kept of all checks and any adjustments found necessary.  
A.2 Polarized systems, phase (L) and neutral (N) – correct connection  
For polarized systems the test shall be made using SELV applied for a period of not 
less than  2 s: 
NOTE 1:    The period of 2 s may be reduced to not less than 1 s on test equipment with automatic 
timing.  
- for plugs and portable socket -outlets, between the remote end of the L and 
N conductors of the flexible cable independently, and the correspondi ng L 
and N pin or contact of the accessory;  
- for cord extension sets, between the L and N pin at one end of the flexible 
cable and the corresponding L and N contact at the other end of the flexible 
cable.  
Polarity shall be correct.

 A.3 Earth continuity  
The test shall be made using SELV applied for a period of not less than 2 s:  
NOTE 1:    The period of 2 s may be reduced to not less than 1 s on test equipment with automatic 
timing.  
- for plugs and portable socket -outlets, between the remote end of the earth 
conductor of the flexible cable, and the earth pin or contact of the accessory, 
as appropriate;  
- for cord extension sets, between the corresponding earth pin or earth contact 
of the accessory at each end of the flexible cable.  
Continuity shall be present.  
A.4 Short -circuit/wrong connection and reduction of creepage distance and 
clearances between phase (L) or neutral (N) to earth ( ) 
The test shall be made by applying at the supply end, e.g. to a plug, for a period of 
not less than 2 s:  
- 2000 V ± 10 % for ac cessories having rated voltage of 230 V;  
NOTE 1:    The period of 2 s may be reduced to not less than 1 s on test equipment with automatic 
timing.  
                       or 
- applying an impulse voltage test using a 1.2/50 µs waveform of 4 kV peak 
value and three impulses for each pole, with intervals of not less than 1 s:  
 between L and , 
 between N and . 
NOTE 2:    L and N may be connected together for this test.  
No flashover shall occur.
