The requirements deal with the geometric charateristics to ensure interchangeability. The dimensions of the joint-ground zone and the outer diameter of the tube connected to the joint are given in a table and illustrated in a drawing. In addition the surface finish is specified. A system of gauges (stell balls) for testing the ball cup is tabled. In the annex a method of testing the leakage…
Statistical interpretation of data — Comparison of two means in the case of paired observations
A method is specified for comparing the mean of a population of differences with zero or any other preassigned value. It may be applied to establish a difference between two treatments, where "treatment" should be understood in a wide sense, e.g. as a test method, measuring instrument or laboratory involved, and is applicable under the conditions that the series of differences can be…
Anhydrous hydrogen fluoride for industrial use — Sampling
This part contains a method for taking laboratory samples intended for the determination of the water content and the preparations of the test samples. Contains instructions for handling with the material. Applicable for taking samples of this highly corrosive liquid from road and rail tanks, drums and cylinders. The principle consists in allowing the liquid of one of these containers to flow in…
Solid dielectric tubular-style rotary variable pre-set capacitors: Grade 2. Part 1: General requirem...
Establishes under laboratory conditions: their suitability for use
over stated ranges of temperature, air pressure and humidity, their
ability to withstand specified conditions of mechanical shock,
their ability to withstand the rigours of normal assembly
processes.
Ceramic dielectric disk-style rotary variable pre-set capacitors: Grade 2. Part 1: General requireme...
Describes the tests on capacitors to establish as far as possible under laboratory conditions: their suitability for use over stated ranges of temperature, air pressure and humidity; their ability to withstand specified conditions of mechanical shock such as are to be expected under transit or operational conditions: their
ability to withstand the rigours of normal assembly processes attendant on…
Gives requirements and characteristics to specify a hydrophone which is suitable as an IEC Standard Hydrophone for calibration purposes, to be used as a laboratory standard for comparison with other hydrophones intended for daily use.
