BSEN 10204 - type 3.2 Inspection Certification
With the introduction of new EC directives, such as the Pressure Equipment Directive
(PED), there is an increasing requirement for materials to prove they meet the
defined chemical and mechanical properties. This has led to the authentication of
material certificate requirements under the standard BSEN 10204:2004. This
factsheet gives more information about achieving certification under type 3.2 of that
standard.
