ISO/TC 128 - Glass plant, pipeline and fittings -- STAND-BY

The components referred to shall be manufactered from borosilicate glass, which is resistent to both heat and chemical attack. They mainly have nominal bores in the range from 80 to 1400 mm. The requirements for compatibility and interchangeability of these components are specified. The dimensions are tabled and shown in drawings.

The rules deal both with the tests by manufacturer and by user. Pressure tests shall be carried out by manufacturer. The required hydraulic pressure test is specified. Additionally storage, installation, maintenance, thermal and mechanical conditions are considered. Operation and safety are described.

The essential requirements deal with the definitions, the material and the working conditions. Thea are governed largely by the properties of the borosilicate glass 3.3 specified in ISO 3585. The ensure interchangeability the general and special dimensions of the components (i.e. pipe sections, adaptors, reducers) are listed and illustrated by drawings.
