What means UNE 471?

EN471 is a specification required by law in order to protect people who work on the roadside, whilst they go about their day to day business. The standards are set by identifying the risks to people. The legislation is drawn up by organizations such as the BSI. This is the minimum standard for high visibility clothing for professional use, test methods and requirements.  The standard states, "where greater conspicuity is required, the higher level of retro reflective material should be used".

What does it mean?

 The latest revision to the standard is EN471:2003 – this is the standard that you must comply with. The EN471 standards are revised every 5 years, if it is considered necessary. The first EN471 standard was written in 1994. Since then, the European Technical Committee requested some amendments to the standard having received requests from test houses and committee members, particularly in terms of design freedom. The overall revision was finished and was implemented in April 2004. The current EN471 standard with the new amendments is EN471:2003.
