Each member body interested in a subject for which a technical committee has been established has the right to be rep

34、neThe machine shall be power driven, equipped with a suitable dynamometer, capable of maintaining a substantially constant rate of traverse of the moving head during the test and fitted with an autographic recorder. It shall comply with the requirements for class 0,5 or 1 of ISO 5893.An inertialess

35、dynamometer shall be used.5.3 GripsThe grips shall be capable of holding the test piece without slippage.Self-tightening grips are recommended.For strip test pieces, provision shall be made to maintain the strip in the appropriate plane of the grips during the test, for example, by attaching suffici

36、ent weights to the free end of the test piece or by fitting a supporting plate, coated with a low-friction material, such as polytetrafluoroethylene (PTFE), to the non-driven grip.5.4 MandrelFor testing ring test pieces (type 6 and type 8), a mandrel shall be provided that is a close sliding fit in

37、the test piece. This mandrel shall be capable of being fitted into the driven head of the machine so that it will rotate freely during the test.6 Test pieces6.1 Types of test piece6.1.1 GeneralEight types of test piece are specified to cover the range of hose constructions and bore sizes normally en
