21、 Foreword The text of the International Standard ISO 10528:1995 has been prepared by Technical Committee ISO/TC 38, Textiles, in collaboration with CEN/TC 248, Textiles and textile products. It has been submitted to the Parallel Vote and has been approved on 1995-04-05 as European Standard. This Eur
22、opean Standard shall be given the status of a National Standard, either by publication of an identical text or by endorsement, at the latest by December 1995, and conflicting national standards shall be withdrawn at the latest by December 1995. According to the CEN/CENELEC Internal Regulations, the
23、following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

25、 soft water. The washing machines specified are all horizontal rotating drum types with reversing action which are already in laboratory use but which differ considerably in cage volume, frequency of rotation and the methods of controlling liquor level and temperature. Alternative procedures for ass
26、essing the effect of domestic washing using hard water on the flammability of textile fabrics are given in ISO 12138:, Textiles Domestic laundering procedure for textile fabrics prior to flammability testing (to be published). The methods specify the use of liquor/load ratios of 5 : 1 for washing an
27、d 9 : 1 for rinsing, which are at the low end of the ranges used in normal laundry practice. For practical reasons they are determined with no fabric present. Extra water is added during the washing procedure but the amounts will vary according to the type of machine used and cannot be controlled. T
28、he specified wash temperature of (75 3) C has been shown to be adequate to ensure sterilization of hospital items, while the use of higher temperatures does not produce any significant improvement in the cleansing effect. Some items may not be suitable for washing at this temperature, because of shr
29、inkage or other factors, and an alternative procedure with a wash temperature of (40 3) C is provided for such fabrics. Different washing machines vary in their mechanical action and in the time taken to heat to the washing temperature. It is also difficult to control the water inlet temperature. A
30、total period of 30 min agitation during heating and washing is specified for the standard wash. This is longer than would be used in practice but it helps to eliminate the uncontrollable variations between different types of installation and ensures that the test is more severe than actual use. In o
31、rder to eliminate variations in the period taken to heat to temperature, agitation is not started until a temperature of (40 3) C is reached. This allows the water input temperature to vary without affecting the period of agitation. In interlaboratory trials carried out by ISO/TC 38/SC 2/WG 6 in 198
32、9, this procedure was found capable of distinguishing between flame retardant finishes with good and poor stability to washing. However, it was noted that the flammability test used to assess the performance of the fabrics (specified in ISO 6941:1984, Textile fabrics Burning behaviour Measurement of
33、 flame spread properties of vertically oriented specimens) gave more variability than this washing procedure when the two methods were used in sequence. 1 Scope This International Standard specifies methods for assessing the possible effect of repeated commercial laundering on the flammability of te
34、xtile fabrics. The effect of laundering is simulated using an automatic horizontal drum washing machine or small-scale laundry drum (wash wheel). 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Stand
35、ard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IE
36、C and ISO maintain registers of currently valid International Standards. ISO 675:1979, Textiles Woven fabrics Determination of dimensional change on commercial laundering near the boiling point.

37、nts 3.1 Washing machine 3.1.1 Automatic washing machine (Type A), equipped with a horizontal rotating drum with reversing action. The drum shall have a diameter of 480 mm to 610 mm and shall be fitted with three or four lifters. It shall rotate at 30 r/min to 52 r/min and reverse its direction every
38、 10 r to 20 r. The liquor level shall be capable of being controlled to both low and high levels, giving liquor volumes of 0,3V1 and 0,54V1, where V1 is the volume of the rotating drum (see 5.1). Means shall be provided for heating and controlling the water temperature. This automatic washing machin
39、e shall be used in accordance with the procedures specified in clause 6 or 7.

Ma
40、chines of Type A1 or A2 as specified in ISO 6330 may be used if they satisfy the liquor level control requirements. 3.1.2 Wash wheel (Type W), as specified in ISO 675, to be used with the procedures specified in clause 8 or 9. This machine has a different reversing action, reversing every 5 r to 10
41、r and is steam-heated. 3.2 Soft water, with a maximum hardness, expressed as calcium carbonate, of 20 mg/l. 3.3 Ballast, consisting of rectangular pieces in single layers of woven 100 % bleached cotton or 100 % polyester. Each piece shall measure at least 350 mm by 500 mm and shall be hemmed along t
42、he cut edges to prevent unravelling. 3.4 Low-foaming detergent, with perborate. For example, the IEC reference detergent or ECE reference detergent, as specified in ISO 6330, may be used. Sodium perborate is added to the detergent immediately before use in the ratio of one part perborate to four par
43、ts of detergent. All detergent quantities quoted below are for the detergent plus perborate. 3.5 Iron, or press, capable of being used at a temperature appropriate for the material being tested. 4 Composition of the load The test specimens shall be of sufficient size for the subsequent flammability
44、testing. The total dry mass of the load shall be as calculated in 5.2 and at least half the load shall consist of material under test or material of similar fibre type, the remainder consisting of polyester ballast (see 3.3). 5 Preliminary calculations 5.1 Drum volume If it is not specified, calcula
45、te the volume V1, expressed in litres, of the rotating drum to the nearest litre, ignoring any space occupied by lifters, using the equation V1 = lr2; 106 where 5.2 Test load Calculate the total dry mass m1, expressed in kilograms, of the test load to the nearest 0,1 kg using the equation m1= (0,060
46、 0,004)V1 5.3 Detergent quantity Calculate the mass m2, expressed in grams, of detergent to be added, to the nearest 0,5 g using the equation m2= (0,30 0,02)V1 5.4 Low dip level Determine the volume of water V2, expressed in litres, required to fill the machine to the low dip level (L) to the neares

48、 using the equation V3= (0,54 0,04)V1 NOTE 2For some machines the dip levels are preset. Other machines require the dip levels to be adjusted to give the specified volumes (see Annex A). 6 Standard washing procedure: automatic machines (Type A) 6.1 Load the machine (3.1.1) with a load of m1, as calc
49、ulated in 5.2 and of the specified composition (see clause 4). Start the machine with reduced agitation and fill with soft water (3.2) at a temperature of 15 C to 40 C to the low dip level (L), at the same time adding the mass m2 of detergent (3.4) as calculated in 5.3. 6.2 If the inlet water temperature is below 37 C, heat to (40 3) C with no agitation. Heat to (75 3) C in (15 3) min with reduced agitation. Switch to normal agitation and run at (75 3) C for (15 0,5) min. Drain. 6.3 Fill with cold soft wate
