Poly Pipe Standards

[verdi]

Hi
Is there a standard for welding pvc pipe and if not how does one prepare a procedure if required including test pieces? Would a 200nb cover everthing below that size?
cheers

1. Requires a high level of training to use and interpret results.
2. Traditionally doesn’t keep a permenent record. ( modern ut machines do these days)
3. Expensive machines and probes
4. Limitated to specific joint geometrys and http://www.saclongchampfranc.net  shapes and surface cobditions (very small very thin very rough and non homogeneous materials are difficult)
5. linear defects orientated parallel to the sound beam may go undetected
