Причина отмены This specification covers chemically resistant, low expansion, Type I, borosilicate glass, Class A (see Specification E438), used to manufacture corrosion-resistant pipe and fittings for drain, waste, and vent service.

Formerly under the jurisdiction of Committee C14 on Glass and Glass Products, this test method was withdrawn in November 2019. This standard is being withdrawn without replacement due to its limited use by industry.

Реферат

This specification covers chemically resistant, low expansion, Type I, borosilicate glass, Class A, used to manufacture corrosion-resistant pipe and fittings for drain, waste, and vent service. The pipe and fittings covered by the specification are intended for chemical resistant service above and below grade under gravity flow or vacuum conditions. The pipe and fittings shall have beaded or plain ends. The chemical and physical requirements shall conform to the requirements specified.
