DIN EN ISO 20471 regulates the general requirements of protective clothing (e.g. ergonomics, size description, ageing process and accompanying manufacturing information). DIN EN ISO 20471 reflects the latest standard of technology with regard to high-visibility clothing. In contrast to EN 471 (prior to 2013), ISO 20471 no longer differentiates between professional and non-professional use of high-visibility clothing. This standard relates to situations where high visibility is required both in professional and private life. The classification within the standard includes, among other things, the specification for the surface covered with the background material and the surface covered with reflective material.
