Cores made of soft magnetic materials - Measuring methods - Part 2: Magnetic properties at low excit...
Gives guidance for the drafting of those parts of specifications for magnetic cores that are concerned with measuring methods for magnetic and electric core properties. Applies to magnetic cores, mainly made of magnetic oxides or metallic powders, used at low excitation level in inductors and transformers for telecommunication equipment and electronic devices employing similar techniques.

ISO 11873:2005 specifies the method to be used for the determination of sulfur and carbon in cobalt metal powders in the range of 0,001 % (m/m) to 0,1 % (m/m) by combustion in oxygen and infrared (IR)-detection of carbon dioxide (CO2) and sulfur dioxide (SO2).
Fibre ropes — Determination of certain physical and mechanical properties
ISO 2307:2004 specifies, for ropes of different kinds, a method of determining each of the following characteristics: linear density, lay length, braided pitch, elongation, and breaking force. The linear density, lay length and braided pitch are measured with the rope under a specified tension called the reference tension.
ISO 2307:2004 also provides a method for measuring water repellency,…
Nuclear power plants - Main control room - Comparison of IEC 60964 to similar standards on control r...
Identifies and reviews standards that are similar in scope to IEC 60964, and compares their content to relevant clauses of IEC 60964. The similar standards include power industry standards, and some closely related guides and regulatory documents. The purpose is to identify areas of IEC 60964 that should be considered for revision.
Polymeric thermistors - Directly heated positive step function temperature coefficient - Part 1: Gen...
IEC 62319-1:2005(E) prescribes terms and methods of test for polymeric positive temperature coefficient thermistors, insulated and non-insulated types, typically intended for use in current limiting and overcurrent protection applications. It establishes standard terms, inspection procedures and methods of test for use in detail specifications for Qualification Approval and for Quality Assessment…
