Standard Test Method for Coking Value of Tar and Pitch (Modified Conradson)

safety is provided because mechanical resistance does not change significantly

semi-rigid polyvinylidene sleeving for use in aircraft electrical systems at operating temperatures between – 55 °C and 175 °C

The requirements are generic and to apply to all organizations

Using BS EN 12390‑17 you can understand the creep of hardened concrete test specimens subjected to a sustained longitudinal compressive load

Controlled replacement of the water in the cold water feed cistern from the water supply by means of a float operated valve

such as integrated gear-driven compressors

Note 3: Copper and alloys containing a high percentage of copper are heavily tarnished in the test atmosphere owing to the formation of copper sulphides

BS EN 13031-1 on design and construction of commercial production greenhouses applies to:

some of the requirements of IEC 60950 for resistance to moisture and liquids are less stringent than those in IEC 61010‑1:2010

based on different standards

The scope of this part of IEC 61851 does not cover box type assemblies with socket-outlets

interface devices
