Materials
EAMs
Materials regularly used for Pressure Equipment
Applied for by Manufacturer of PE or material
Issued by Notified Body
May take many months to publish in OJ
New materials may require testing
When approved may be used by any
manufacturer

PMAs
Materials
Any material may be used providing:
Manufacturer ensures material
is suitable for “particular”
application and meets ESRs for
material
Provide evidence of compliance
with allowable specification, i.e.
Harm Std, EAM, PMA
No set format for documentation.
If specific quantitative
requirements not met,
justification required
(equivalent overall
level of safety?)
Notified Body performs
particular appraisal for
equipment in Cats III & IV
Decisions made concerning one material
do not have to repeated

Certification
Materials
Materials must:
Material
Certification
Cat 1 - (2.2)
Cat II, III, IV (3.1)
be accompanied by
documentation issued by the
material manufacturer
affirming conformance to a
specification.
Cat 1 - Certificate of conformity
Cat II, III, IV - specific product
control - e.g. (EN 10204 - 3.1) {prepared by material
manufacturer}

Materials
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
