MS ISO 4427-1:2019 – Plastics piping systems for water supply and for drainage and sewerage under pressure — Polyethylene (PE) — Part 1: General

Scope:
The MS 10:2015+A2:2009 is an adoption of the BS 4449 which is a British standard on steel for the reinforcement of concrete that discusses the criteria for manufacturing ribbed weldable reinforcing steel. BS 4449 specifies requirements for ribbed weldable reinforcing steel used for the reinforcement of concrete structures. BS 4449 covers steel delivered in the form of bars, coils, and decoiled products. BS 4449 contains provisions for three steel grades, all of 500 MPa characteristic yield strength, but with different ductility characteristics. The three grades are B500A, B500B, and B500C.
