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

however for a dedicated LPG standard see EN 12493

It is intended to provide guidance for controlling such exposures as a cautionary measure where neither relevant exposure standards nor definitive hazard and exposure information exist

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

Polyolefin pipes for the conveyance of fluids — Determination of resistance to crack propagation — Test method for slow crack growth on notched pipes seo-ignore fine concrete screeds and to1 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.
