This document specifies a non‑destructive penetrant testing for determining bond defects and discontinuities in the sliding surface of the bearing.
The penetration method is used to detect
a) bond defects in the transitional area between the bearing backing/bearing material on the end faces and joint faces of multilayer plain bearings which cannot be detected by the ultrasonic testing method…
This document specifies requirements for non-alloy and alloy steels that are intended for cold heading or cold extruding and are delivered as wire rods, wire or bars. It also contains specific requirements for:
— steels not intended for heat treatment, with diameters from 2 mm to 100 mm (see Annex A);
— case-hardening steels with diameters from 2 mm to 100 mm (see Annex B…
Radiological protection — Measurement for the clearance of waste contaminated with radioisotopes for...
This document establishes a method for radioactivity measurement and determination of the storage periods of the radioactive wastes produced as a result of the medical application of radioisotopes based on counting measurements using a detector and decay correction of the initial activity concentration of the radioisotopes contained in the waste stream.
It provides a set of controls and…
