16、16419:2014-06 EN 16419:2014 (E) 4 Introduction Chamois leather 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 peri

17、od. Chamois leather for cleaning purposes is made only from first 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

18、all over the surface. Their appearance is soft, velvety on both sides, without any traces of grain, holes, cuts and seams. DIN EN 16419:2014-06 EN 16419:2014 (E) 5 1 Scope This European Standard applies to chamois leather for cleaning purposes and defines both requirements and standard test methods.
