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
