17、n) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be rep

18、resented on that committee. International organizations, governmental and non- governmental, in liaison with ISO, also take pari in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Stan

19、dards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

21、tional Standard provide standardized domestic laundering procedures for use prior to assessing the likely flammability behaviour of textile materials. The methods are based on IS0 6330 but incorporate several additional features which ensure that certain critical parameters are more closely controll

22、ed. Alternative procedures for commercial laundering prior to assessing the flammability of textile fabrics are given in IS0 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 laun

23、dering under all possible conditions. The methods specified, however, can be 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 treat

24、ed with flame retardants. The flammability of textile materials can be affected by a combination of different results: - shrinkage of the material, causing an increase in mass per unit area; - abrasion of the material, causing a decrease in mass per unit area; - removal of finishes: - chemical modif

25、ication of the fibre or finish: - deposition of hard-water salts; - including application of softeners in the rinse cycle. The various factors in these test methods are controlled in order to standardize all these effects as far as possible. The essential features specified in the methods are: a) wa

26、ter 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 the initial water supply. b) degree of loading and

27、 composition of load; These factors influence the mechanical action of the washing machine and the deposition results. iii STDmBSI BS EN IS0 L2138-ENGL 1777 lb24bb7 Ob00424 582 EN IS0 12138 : 1996 volumes of liquor used for washing and rinsing; The 1iquor:fabric ratio affects the mechanical action a

28、nd the deposition results. In addition, it is essential to know the volumes of water being used in order to make any necessary adjustments to the water hardness. type and quantity of detergent; The use of a standard nonphosphate detergent containing sodium perborate and a bleach activator is recomme

29、nded because of the increasing use of this type of detergent. The detergent used shall be agreed between the interested patties. 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 t

30、he nonphosphate builders included in the formulation. 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 detergent used in this International St

31、andard is not suitable for laundering flame-retardant materials at temperatures above 60 OC. 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 filling and heating in

32、 order to avoid variations in mechanical action. Normal agitation is specified for the 12-min washing period for washes at 50 OC and 60 OC, but reduced agitation is used during the washing period for 30C and 40C washes. rinsing procedure; A standard rinsing procedure is specified, as rinsing can hav

33、e considerable influence on the deposition of hard-water salts. Fabric softeners added to the rinse are not used in this method. washing machine. The methods as presented allow the use of two different types of washing machine. As far as possible the same laundering conditions have been specified fo

34、r 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 1iquor:fabric ratio is 5,O:l ,O for washing and 9,O:l ,O for rinsing. The mechanical action and the 1iquor:fabric r

35、atio (20:l) used in the vertical drum machine (Type B) 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 may be different. . iv - STD-B
