19、surface of a floor covering, under specified conditions of temperature, pressure and time. This is followed by a visual examination of the absorbent material. 3 Apparatus and materials 3.1 A ventilated oven, capable of being maintained at(80 2) C. 3.2 Absorbent paper, mass per unit area approximatel
20、y15g/m 2 , ash content3%, size of sheets approximately70mm 40mm. NOTECigarette paper without adhesive is suitable for this test. 3.3 A metal plate measuring50mm 25mm 1mm. 3.4 A mass of500g 3.5 A flat, horizontal, metal surface 4 Sampling and preparation of test pieces Take a representative sample fr
21、om the available material. Take six test pieces at equal distances across the sample, the distance between the outer edge of the sample and the nearest edge of the test piece being at least100mm, of minimum dimensions50mm 25mm. 5 Conditioning Condition the test pieces at a temperature of(23 2) C and
22、 relative humidity(50 5)% for a minimum of24h. Maintain these conditions when carrying out the test. 6 Procedure Place the first test piece on the flat surface with its surface layer uppermost. Place a single sheet of absorbent paper on top of it, then place a second test piece on this sheet with it
23、s surface layer downwards, exactly over the first test piece. Arrange a further two pairs of test pieces in the same way on the pile; cover the pile completely with the rigid metal plate and place the500g weight on top. Place the entire combination in the oven which has been pre-heated to80 C. After
24、24h, allow to cool at the ambient temperature and separate the test pieces. Examine the sheets of paper with the naked eye under diffuse lighting to see whether there are any traces of grease or colour. 7 Expression of results Report the presence of any stains and, where applicable, their colour. 8
25、Test report The test report shall contain the following information: a) a reference to this standard, i.e.EN665; b) a complete identification of the product tested, including type, source and manufacturers reference numbers; c) the previous history of the sample; d) the presence, or otherwise of any
26、 stains, and where applicable, their colour; e) any deviation from this standard which may have affected the results.4 blankBSEN665:1995 BSI 01-2000 National annex NA (informative) Committees responsible The United Kingdom participation in the preparation of this European Standard was entrusted to T
