Method for the Measurement of Sulphur Dioxide in Air
1. Scope
1.1 This Standard applies to the measurement of the concentration of sulphur dioxide in air.
1.2 This Standard sets forth the Pararosaniline Colorimetric Procedure based on the West-Gaeke Method as the reference method for the measurement of sulphur dioxide in the range 25 to 1000 µg·m-3 at 25°C and 101.3 kPa.
Note. All concentrations referred to throughout this Standard…
Vacuum technology — Quick release couplings — Dimensions — Part 2: Screwed type
ISO 2861-2:1980 specifies the dimensions of quick-release couplings of the screwed type as used in vacuum technology, as well as those of the “O” rings and the insert which are associated with these tailpieces to ensure coupling tightness.
General information is also included which refers to the clamped quick-release coupling standardized internationally in ISO 2861-1, with which the screwed…
