ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and

21、 those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

25、 by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 2, Cleansing, finishing and water resistance tests.This second edition cancels and replaces the first edition (ISO 12138:1996), which has been technically revised.The main changes compared to the previous edition are as follows: The text w

26、as updated to use the washing machine technology currently available. Referenced herein, ISO 6330:2012 incorporated significant changes to washing machines compared to its previous editions. This second edition of ISO 12138 incorporates those updates, throughout. Additionally, this second edition in

27、corporates a reference to ISO 139, which provides direction for atmospheric conditioning prior to flammability testing.iv ISO 2017 All rights reservedBS EN ISO 12138:2018ISO 12138:2017IntroductionThe methods specified in this document provide standardized domestic laundering procedures for use prior

28、 to assessing the likely flammability behaviour of textile materials. The methods are based on ISO 6330:2012 but incorporate several additional features which ensure that certain critical parameters are more closely controlled. Alternative procedures for commercial laundering prior to assessing the

29、flammability of textile fabrics are given in ISO 10528.Because of the wide variety of laundering methods used domestically, it is impossible to specify a standard laundering procedure which will reproduce the effect of laundering under all possible conditions. The methods specified, however, can be

30、used to detect which materials are adversely affected by domestic laundering under conditions which are appropriate for the material being laundered. Such adverse effects are not restricted to textiles which have been treated with flame retardants.The flammability of textile materials can be affecte

31、d by a combination of different results: fibre content; effect of mechanical finishing/surface texture changes; shrinkage or growth of the material, causing a change in mass per unit area; abrasion of the material, causing a decrease in mass per unit area; removal of finishes; chemical modification

32、of the fibre or finish; deposition of hard-water salts; including application of softeners in the rinse cycle; moisture content of the product under flammability evaluation.The various factors in these test methods are controlled in order to standardize all these effects as far as possible. The esse

33、ntial features specified in the methods are:a) water hardness;A medium water-hardness level is specified in order to ensure that any major effects caused by deposition or chemical modification are detected. Different procedures for preparing this hard water are given, depending on the hardness of th

34、e initial water supply.b) degree of loading and composition of load;These factors influence the mechanical action of the washing machine and the deposition results.c) volumes of liquor used for washing and rinsing;The liquor:fabric ratio affects the mechanical action and the deposition results. In a

35、ddition, it is essential to know the volumes of water being used in order to make any necessary adjustments to the water hardness.d) type and quantity of detergent;The use of a standard nonphosphate detergent containing sodium percarbonate and a bleach activator is recommended because of the increas

36、ing use of this type of detergent. The detergent used shall be agreed between the interested parties. The detergent can affect the chemical modification of a material or finish by its bleaching action, and also affects the deposition because of the sequestering effect of the nonphosphate builders in

37、cluded in the formulation. ISO 2017 All rights reserved vBS EN ISO 12138:2018ISO 12138:2017e) wash temperatures;Four standard wash temperatures are specified so that the appropriate temperature for the material being laundered can be selected.NOTE The combination of hard water and high perborate det

38、ergent used in this document is not suitable for laundering flame-retardant materials at temperatures above 60 C.f) degree of agitation;The heating period can vary considerably depending on the inlet water temperature and the heating capacity of the washing machine. Reduced agitation is used during

39、filling and heating in order to avoid variations in mechanical action. Normal agitation is specified for the 12-min washing period for washes at 50 C and 60 C, but reduced agitation is used during the washing period for 30 C and 40 C washes.g) rinsing procedure;A standard rinsing procedure is specif

40、ied, as rinsing can have considerable influence on the deposition of hard-water salts. Fabric softeners added to the rinse are not used in this method.h) washing machine.The methods as presented allow the use of three different types of washing machine. As far as possible the same laundering conditi

41、ons have been specified for each type of machine. The degree of loading is 60 g per litre of drum volume, and the detergent quantity is 20 g per kilogram of wash load. For horizontal drum machines (Type A), the liquor:fabric ratio is 5,0:1,0 for washing and 9,0:1,0 for rinsing.The mechanical action

42、and the liquor:fabric ratio (20:1) used in the vertical drum machine (Types B and C) are different from those used in the Type A machines. Experience indicates that testing with this type of machine is equally effective in detecting finish removal, although mechanical effects and deposition results

43、may be different.vi ISO 2017 All rights reservedBS EN ISO 12138:2018Textiles Domestic laundering procedures for textile fabrics prior to flammability testing (ISO 12138:2017)1 ScopeThis document specifies methods for repeated domestic laundering at selected wash temperatures prior to assessing flamm
