Reference to the values and to the tests for conduits are made in one relevant conduit specifications taking into account the manufacturer's instructions for bending, so far as they do not contravene the aims of this specification as a whole.
COMPRESSION TEST
Samples of conduit, each 200 mm long, shall be subjected to a compression test using the apparatus shown in Fig. Before the test, the outside diameter of the samples shall be measured. The samples shall then be conditioned at a temperature of 27 2C for at least 10 hours.
Immediately after the conclusion of conditioning period, the samples shall be positioned on a flat steel support and a steel intermediate block as shown in Fig. is placed on the middle of the sample. Slowly increasing force as shown in Table for different types of conduits shall then be applied to the intermediate piece within 30 seconds.
