Materials regularly used for Pressure Equipment

Applied for by Manufacturer of PE or material

New materials may require testing

Issued by Notified Body

May take many months to publish in OJ

When approved may be used by any manufacturer

EAMs Issued to date:

Nickel 201 Four different product forms

Hastelloy Plate in different alloys

Alloy 600 Four different product forms

PMA

Notified Body performs particular appraisal for

equipment in Cats III & IV

Provide evidence of compliance with allowable specification, i.e.

Harm Std, EAM, PMA No set format for documentation.

Manufacturer ensures material is suitable for “particular”

application and meets ESRs for material

If specific quantitative requirements not met, justification required(equivalent overall

level of safety?)

Decisions made concerning one material do not have to repeated

Materials must:

MaterialCertification

Cat 1 - (2.2)

Cat II, III, IV - (3.1)

Cat 1 - Certificate of conformity

be accompanied by documentation issued by the material manufacturer affirming conformance to a specification.

Cat II, III, IV - specific product control - e.g. (EN 10204 - 3.1) -

{prepared by material manufacturer}

MaterialsMaterialsCertification5


MaterialCertification

e.g.

ISO 9001-2000Certification BodyEstablished in EU

Material manufacturer’s certificate acceptable only if:

Material manufacturer has Quality System, e.g. ISO 9000, approved by competent body established in EU,

If not: independent witness, e.g. (EN 10204-3.2) Guideline 7/5

MaterialsMaterialsCertification5


Certificates of conformity EN 10204 - 2.2

Not main pressure part unless failure causes catastrophic release of pressure
