英文名称：Glass-reinforced thermosetting plastics (GRP) pipes and fittings — Test methods to prove the design of bolted flange joints
发布日期：2019-08
标准范围
This document specifies methods of test for bolted flange joints for buried and above-ground glass-
reinforced thermosetting plastics (GRP) piping systems. This document is only applicable to the joint
and covers methods of test to prove its design. It assumes that the joint either is or is not intended to be
subject to the effects of hydrostatic end thrust.
The tests detailed in 9.2, 9.4 to 9.6 inclusive are applicable to bolted flange joints intended to be used
in buried or above-ground applications. The bending tests detailed in 9.3 can be used to prove the
design where joints are either intended to be used in buried applications or are intended to be used in
particular above-ground situations where the tests may be considered appropriate.
With the exception of the procedure detailed in 9.3, these test procedures are applicable to joints
for pipes and fittings of all nominal sizes. The tests detailed in 9.3 are applicable to joints for pipes
and fittings up to and including DN 600. The tests are applicable for evaluating joints intended for
applications conveying liquids at temperatures specified in the referring standards.
The test procedures in this document are damaging to the test piece, which will not be suitable for
reuse after these tests. The test procedure is intended for type testing purposes.
This document is applicable only to the joint and specifies methods of test to prove its design.
