Butadiene for industrial use — Determination of hydrocarbon impurities — gas chromatographic method
Covers a method based on the selection of a gas chromatography column allowing the separation of the impurities to be determined. A gaseous test portion is passed through this column and the peaks obtained are detected by flame ionization and compared with those derived from an external standard. Columns and operating conditions having been found suitable for such a test are indicated in Annex A…

Propylene for industrial use — Determination of hydrocarbon impurities — Gas chromatographic method
Covers a method based on the selection of a gas chromatography column allowing the separation of the impurities to be determined. A gaseous test portion is passed through this column and the peaks obtained are detected by flame ionization and compared with those derived from an external standard. Uses two types of columns, one for the determination of methane, ethane and acetylene (adsorption…

Electromagnetic Interference Measuring Instrument - ANSI Type
1. Scope
1.1 This Standard sets forth the characteristics of an instrument conforming to the requirements of ANSI Standards C63.2, Ra dio-Noise and Field-Strength Meters 0.015 to 30 Megacycles/Second, and C63.3, Radio-Noise and Field-Strength Meters 20 to 1,000 Megacycles/Second, for the measurement of electromagnetic interference, both conducted and radiated, in the frequency range 0.15…
Aircraft — Joints for connecting crew members' regulator masks to oxygen sources
Gives joint lock dimensions for connecting these masks to sources in aircraft and helicopters. Joint dimensions standardization provides interchangeability with masks of various types. The basic dimensions and tolerances are shown in figures 1 and 2. Dimensions without tolerances can correspond to national standards. The lock halves shall be installed as shown in figures 1 and 2.
The oil shall be a clear mobile liquid which may become cloudy or crystalline at low temperatures. The colour shall be yellow to brownish-yellow, the odour characteristic, recalling safrole. The relative density at 20/20 °C has to ly between 1,082 and 1,094 and the refractive index at 20 °C between 1,5330 and 1,5370. The optical rotation shall range from - 0,50 to + 3,0 . The miscibility with 90…
Textile fabrics — Determination of resistance to water penetration — Hydrostatic pressure test
A specimen is subjected to a steadily increasing pressure of water on one face, under standard conditions, until penetration occurs in three places. The water pressure may be applied from below or from above the test specimen. The hydrostatic head supported by a fabric is a measure of the resistance to the passage of water through the fabric.
