Guideline G-30

WGP date: 08/01/2016

Guideline related to: Annex I Section 4.3

Question

A manufacturer produces material only to a chemical analysis without mechanical testing and without affirmation of compliance to a material specification and/or grade. An entity intends to purchase the material and affirm compliance to a material specification by performing the mechanical tests as required by that material specification. There will be no further processing, other than cutting to size. Is this procedure acceptable and may this material be used in pressure equipment under the PED?

Answer

No, even if the mechanical tests are recorded in an EN 10204 inspection certificate which describes the testing entity as the manufacturer of the material.

Reason:
Section 4.3 Annex I of the PED requires the material manufacturer to affirm the compliance with a specification. Any entity who is not involved in the material manufacturing process cannot be considered as a material manufacturer.
