Technical drawings — Railway applications — Part 1: General principles
ISO 21267-1:2003 lays down requirements for the preparation, administration and reproduction of technical drawings for railway applications. It complies with the requirements of EN, ISO or IEC Standards for technical drawings. It applies to technical drawings for railways, irrespective of technology i.e. mechanical, pneumatic, hydraulic, electronic etc.
ISO 21267-1:2003 applies throughout the…
Metallic materials — Brinell hardness test — Part 1: Test method
ISO 6506-1:2014 specifies the method for the Brinell hardness test for metallic materials. It is applicable to both fixed location and portable hardness testing machines.
For some specific materials and/or products, particular International Standards exist (e.g. ISO 4498) and make reference to this International Standard.
Building construction machinery and equipment — Portable, hand-held, internal combustion engine-driv...
This International Standard specifies safety requirements, and measures for their verification, for the design and construction of portable, hand-held, internal combustion engine-driven machines for abrasive chains, intended to be used by a single operator in the cutting of construction materials, such as concrete, stone and metal. It is applicable only to those machines designed purposely for…
An adhesion evaluation method for microcircuits on PCB (Printed Circuit Board) by scratch test
This document describes a method for measuring adhesion strength between microcircuits and substrates by scratching with the wedged-shape diamond stylus. Using the traditional adhesion test, it is difficult to evaluate the adhesion strength of the microcircuits with a narrower scratching stylus.
During the test, applying stylus force is constant or progressive and normal to the surface. This…
Railway infrastructure — Rail welding — Part 2: Aluminothermic welding
This document corresponds to the subsequent part of ISO 23300-1 "General requirements and test methods for rail welding" and specifies the requirements on rail aluminothermic welding, including the requirements for approval of an aluminothermic welding process, laboratory tests, contractor/welder, as well as the acceptance criteria of aluminothermic welds in track. In this document, 43…
