ISO 10528:1995(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards 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. International Standard ISO 10528 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 2, Cleansing, finishing and water t-esis tance tes ts. Annex A of this International Standard is for information only. 0 ISO 1995 All rights reserved.

0 ISO ISO 10528:1995(E) The methods specified in this International Standard simulate the effect of commercial laundry procedures using soft water. The washing ma- chines specified are all horizontal rotating drum types with reversing action which are already in laboratory use but which differ considerably in tage volume, frequency of rotation and the methods of controlling liquor level and temperature. Alternative procedures for assessing the effect of domestic washing using hard water on the flammability of textile fabrics are given in ISO 12 138:-, 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:l for washing and 9:l 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. The 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 shrinkage 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. lt is also difficult to control the water inlet temperature. A 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 Order 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 1989, 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 flame spread properties of vertically oriented specimens) gave more variability than this washing procedure when the two methods were used in sequence.

INTERNATIONAL STANDARD 0 ISO ISO 10528:1995(E) Textiles - Commercial laundering procedure for textile fabrics Prior to flammability testing 1 Scope This International Standard specifies methods for as- sessing the possible effect of repeated commercial laundering on the flammability of textile fabrics. The effect of laundering is simulated using an automatic horizontal drum washing machine or small-scale laun- dry drum (wash wheel). 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, 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 re- cent editions of the Standards indicated below. Members of IEC and ISO maintain registers of cur- rently valid International Standards. ISO 675:1979, Textiles - Woven fabrics - Determi- na tion of dimensional Change on commercial laundering near the boiling Point. ISO 6330: 1984, Textiles - Domestic washing and drying procedures for textile tes ting. 3 Apparatus and reagents 3.1 Washing machine. 3.1.1 Automatic washing machine (Type A), equipped with a horizontal rotating drum with revers- ing action. The drum shall have a diameter of 480 mm to 610 mm and shall be fitted with three or four Iifters. lt shall rotate at 30 r/min to 52 r/min and reverse its direction every 10 r to 20 r. The liquor Ievel shall be capable of being controlled to both low and high lev- els, giving liquor volumes of 0,3V, and 0,54V,, where VI is the volume of the rotating drum (see 5.1). Means shall be provided for heating and controlling the water temperature. This automatic washing machine shall be used in ac- cordante with the procedures specified in clause 6 or 7. NOTE 1 This definition allows the use of a wider range of machines than ISO 6330. Machines of Type Al or AZ 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, revers- ing every 5 r to 10 r and is steam-heated. 3.2 Soft water, with a maximum hardness, ex- pressed as Calcium carbonate, of 20 mg/l. 3.3 Ballast, consisting of rectangular pieces in sin- gle layers of woven 100 % bleached cotton or 100 % Polyester. Esch piece shall measure at least 350 mm by 500 mm and shall be hemmed along the tut edges to prevent unravelling. 3.4 Low-foaming detergent, with Perborate. For example, the IEC referen
