CEN/TR 15642:2011

This Technical Report specifies the tests procedures for some of the tests required by EN 3-7:2004+A1:2007; it does not cover all the EN 3-7:2004+A1:2007 tests but only the tests requiring more precision in their execution.
These Unified Tests Procedures are in force for all laboratories performing EN 3-7:2004+A1:2007 tests. Those laboratories should be accredited to EN ISO/IEC 17025 for EN 3-7:2004+A1:2007 tests and their accreditation shall be done by an Accreditation Body, member of the European Accreditation.
This document should be included in the list of applicable documents.
NOTE Since results of many tests may be affected by the human factor, this document should be taken as a helpful tool but will not replace experience and knowledge of people.”
