Plastics — Unsaturated-polyester resins — Measurement of gel time at ambient temperature
This International Standard specifies methods of measuring, under defined conditions, the gel time at ambient
temperature (i.e. within the range 18 °C to 30 °C) of unsaturated-polyester resins.
The referee temperature, if needed, is 25 °C.
Pneumatic fluid power — Directional control valves — Measurement of shifting time
This International Standard
— specifies test procedures for measuring the shifting times of electrically- or pneumatically-operated directional
control valves and moving-part logic elements,
— establishes a definition for shifting time, and
— is intended to improve the application of pneumatic fluid power by providing users and manufacturers of
pneumatic valves with a standardized test procedure…
Optical fibres - Part 1-47: Measurement methods and test procedures - Macrobending loss
Establishes uniform requirements for measuring macrobending sensitivity for category B1 to B4 single-mode optical fibres at 1550 nm and of category A1 multimode fibres at 850 nm and 1300 nm. The standard gives two methods for measuring macrobending sensitivity: power monitoring and cut-back.

Flexible insulating sleeving - Part 3: Specifications for individual types of sleeving - Sheets 121 ...
Gives the requirements for four types of non-heatshrinkable sleeving, extruded from silicone elastomer. These sleevings are normally available with internal diameter up to 25 mm and in a range of wall thicknesses between 0,1 mm and 2,0 mm. National standards may select a restricted list of preferred combinations of internal diameter and wall thickness.
