Petroleum and related products — Determination of the ageing behaviour of inhibited oils and fluids ...
ISO 4263:2006 specifies a method for the determination of the ageing behaviour of gear oils of categories CKC, CKD, CKS and CKT as defined in ISO 6743-6. The ageing is accelerated by the presence of air and elevated temperatures, and the degradation of the oil is assessed by the change in kinematic viscosity at 100 °C, the insoluble content (precipitation number), and possibly the acid number…

Integrated circuits - Measurement of electromagnetic immunity, 150 kHz to 1 GHz - Part 1: General co...
This part of IEC 62132 provides general information and definitions on measurement of conducted and radiated electromagnetic immunity of integrated circuits (ICs) to conducted and radiated disturbances. It also provides a description of measurement conditions, test equipment and set-up, as well as the test procedures and content of the test reports. A test method comparison table is included in…
Covers minimum requirements for ventilated and electrically heated single-chamber ovens, with or without forced gas circulation, for thermal endurance evaluation of electrical insulation. It covers ovens designed to operate over all or part of the temperature range from 20 °C above ambient to 500 °C. It gives acceptance tests and in-service monitoring tests for these ageing ovens.
