Safety devices for protection against excessive pressure

Assessment of CEN Consultant on PED on FprEN ISO 4126-1, - 4, - 5

Mr Ed Haynes, CEN Consultant on PED, has made an assessment on the following draft standards and has made comments with regard to the relationship between them and ISO 4126-7 “Safety devices for protection against excessive pressure -- Part 7: Common data” (which is already published).

FprEN ISO 4126-1 “Safety devices for protection against excessive pressure - Part 1: Safety valves”

FprEN ISO 4126-4 “Safety devices for protection against excessive pressure - Part 4: Pilot operated safety valves”

FprEN ISO 4126-5 “Safety devices for protection against excessive pressure - Part 5: Controlled safety pressure relief systems (CSPRS)”

CEN/TC69/WG10 needs to consider these comments prior to the next revision or amendment to the standards.

However the assessment is positive, therefore the draft standards FprEN ISO 4126-1, -4, -5 may be submitted to parallel Formal / FDIS Vote.
