It has been submitted to the Parallel Vote and has been approved on1995-
20、04-05 as European Standard. This European Standard shall be given the status of a National Standard, either by publication of an identical text or by endorsement, at the latest by December1995, and conflicting national standards shall be withdrawn at the latest by December1995. According to the CEN/
21、CENELEC Internal Regulations, the 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. NOTENormative refer
22、ences to International publications are listed in Annex ZA (normative).ENISO10528:1995 BSI 04-1999 3 Introduction The methods specified in this International Standard simulate the effect of commercial laundry procedures using soft water. The washing machines specified are all horizontal rotating dru
23、m 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 assessing the effect of domestic washing using hard water on the flammability
24、of textile fabrics are given in ISO12138:, Textiles Domestic laundering procedure for textile fabrics prior to flammability testing (to be published). The methods specify the use of liquor/load ratios of5:1 for washing and9:1 for rinsing, which are at the low end of the ranges used in normal laundry
25、 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 s
26、terilization 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
27、 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 total period of30min agitation during heating and washing is specified for the stand
28、ard 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
29、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/TC38/SC2/WG6 in1989, this procedure was found capable of distinguishing between flame retardant finishes with
30、 good and poor stability to washing. However, it was noted that the flammability test used to assess the performance of the fabrics (specified in ISO6941:1984, Textile fabrics Burning behaviour Measurement of flame spread properties of vertically oriented specimens) gave more variability than this w
31、ashing 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 textile fabrics. The effect of laundering is simulated using an automatic horizontal drum wash
32、ing 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 Standard. At the time of publication, the editions indicated were valid. All standards are subjec
33、t 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.

35、otating drum with reversing action. The drum shall have a diameter of480mm to610mm and shall be fitted with three or four lifters. It shall rotate at30r/min to52r/min and reverse its direction every10r to20r. The liquor level shall be capable of being controlled to both low and high levels, giving l
36、iquor volumes of0,3V 1and0,54V 1 , where V 1is the volume of the rotating drum (see5.1). Means shall be provided for heating and controlling the water temperature. This automatic washing machine shall be used in accordance with the procedures specified in clause6 or7.ENISO10528:1995 4 BSI 04-1999 NO
37、TE 1This definition allows the use of a wider range of machines than ISO6330. Machines of Type A1 or A2 as specified in ISO6330 may be used if they satisfy the liquor level control requirements. 3.1.2 Wash wheel (Type W), as specified in ISO675, to be used with the procedures specified in clause8 or
38、9. This machine has a different reversing action, reversing every5r to10r and is steam-heated. 3.2 Soft water, with a maximum hardness, expressed as calcium carbonate, of20mg/l. 3.3 Ballast, consisting of rectangular pieces in single layers of woven100% bleached cotton or100% polyester. Each piece s
39、hall measure at least350mm by500mm and shall be hemmed along the 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 ISO6330, may be used. Sodium perborate is added to the detergent immediat
40、ely before use in the ratio of one part perborate to four parts 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
41、 shall be of sufficient size for the subsequent flammability testing. The total dry mass of the load shall be as calculated in5.2 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 c
