Steel wire for mechanical springs - Part 1: Patented cold drawn unalloyed spring steel wire
Käsitlusala:
This document applies to patented cold drawn unalloyed steel wire of circular cross-section for the manufacture of mechanical springs for static duty and dynamic duty applications. General technical delivery requirements can be found in EN 10021.
Ductile iron pipes and fittings — Seal coats for cement mortar linings
Käsitlusala:
This document specifies the requirements for seal coatings for factory application to the surfaces of cement mortar linings, which are factory applied to the interior of ductile iron pipes and fittings. It provides the performance requirements for short-term sealing efficiency, long-term durability and cyclic pressure, as well as the routine testing requirements for visual appearance, coating thickness and adhesion. This document is applicable to products for potable and irrigation water and for other applications as per agreement between manufacturer and customer.
