7 Qualification of other valves by representative size, pressure rating and materials of construction
7.1 General
Instead of testing each nominal size and nominal pressure rating of a given valve design, all valves of the same basic design as the test valve may be deemed to have been fire-tested, subject to the following limitations.
a) The type of valve body ends are not considered by this International Standard. However, the mass of the valve is determined in part by the body end type. For qualification to the present International Standard, and providing that all other qualification cntena have been met, valves with ends different to those of the test valve may also qualify provided that
their mass is greater than that of the test valve, or
their mass is not less than 75 % of that of the test valve,
7.2 MaterIals of construction
7.2.1 For the purposes of product compliance certification or type testing systems, the materials of construction of the pressure retaining envelope of the valve shall be deemed to qualify other materials of construction within the generic classifications below.
— Ferritic
Austenitic
— Duplex
7.2.2 If a range of valves is covered by testing of ferritic test valves then the type-testing coverage may be extended to cover austenitic or duplex materials by carrying out a further test on a mid-range size of valve of the same design in that material.
7.2.3 Other materials of construction of the pressure-retaining envelope of the valve require full testing of representative size and pressure ratings as specified in 7.3 and 7.4.
7.2.4 Ailoy steel bolting (e.g. 87, L7) used as part of the valve’s pressure-retaining envelope may be used to qualify austenitic steel bolting but not vice-versa.
7.2.5 Any change In non-metallic materials with respect to the seat-to-closure member seal, seat-to-body seal, stem seal and body joint and seal require a re-qualification. Filled PTFE. however, may qualify non-filled PTFE and vice-versa.
