BS EN 16419:2014EN 16419:2014 (E) 4 Introduction Chamois leather

15、for cleaning purposes is used notably for drying and polishing smooth surfaces, such as car bodies and windows. Its properties are the rapid absorption and release of water, performances that remain unaltered even after a long usage period. Chamois leather for cleaning purposes is made only from fir

16、st choice ovine skins. Generally, chamois leather is trimmed before sale only in order to achieve a homogenous and symmetrical size or shape. Chamois leathers have the natural colour conferred by the oil tanning, homogeneous and uniform all over the surface. Their appearance is soft, velvety on both

17、 sides, without any traces of grain, holes, cuts and seams. BS EN 16419:2014EN 16419:2014 (E) 5 1 Scope This European Standard applies to chamois leather for cleaning purposes and defines both requirements and standard test methods. 2 Normative references The following documents, in whole or in part
