Polyolefin pipes for the conveyance of fluids — Determination of resistance to crack propagation — Test method for slow crack growth on notched pipes seo-ignore All care should be taken

All care should be taken to ensure that the samples are representative of the specified system

Instructions for conversion to other gases

1   These test methods cover the determination of water vapor transmission (WVT) of materials through which the passage of water vapor may be of importance

in this case the pressurized part only for low pressure and controlled atmosphere plasma spraying

ISO 23920 specifies a method for the quantification of ammonia by ion chromatography in mainstream smoke using ISO 20778 smoking parameters

Polyolefin pipes for the conveyance of fluids — Determination of resistance to crack propagation — Test method for slow crack growth on notched pipes seo-ignore All care should be taken1 Scope This International Standard specifies a test method for determining the resistance to slow crack growth of polyolefin pipes, expressed in terms of time to failure in a hydrostatic pressure test on a pipe with machined longitudinal notches in the outside surface. The test is applicable to pipes of wall thickness greater than 5 mm.
