Aircraft — Fire-resisting electrical cables — Dimensions, conductor resistance and mass
Includes the characteristics of cables with single copper conductors, for use at a nominal voltage of 6OO V, a maximum frequency of 2 OOO Hz and a continuous temperature not exceeding 28O °C (ambient temperature plus heating) but which may withstand 4OO °C for a limited period. The cables will retain a certain amount of dielectric strength when subjected to a flame of 1 1OO °C for 5 min.
Gives the requirements for cables for the wiring of aircraft circuits, comprising single conductors with copper core covered with nickel or any other material of equivalent properties, suitable for use at a rated voltage up to 6OO V and at a frequency not exceeding 2 OOO Hz. The cables are intended for use at a temperature which may reach 28O °C in continuous service (ambient temperature plus…
Aircraft — Fire-resisting electrical cables — Methods of test
Specifies the tests suitable for establishing the compliance of cables with the performance requirements stated in ISO 2155. Is intended to serve as a basis for test specifications to be included in the relevant national standards when the Official Board of Inspection considers that existing tests are inadequate. The tests are classified in type tests only, type tests and routine productions…
Aluminium oxide primarily used for the production of aluminium — Particle size analysis — Sieving me...
Specifies a method for determining the mass distribution of the particle sizes of diameter 50 m and more. The procedure based on mechanical sieving of the crude sample, dried at 100 °C, through woven wire sieves in an atmosphere of relative humidity not more than 50 %. Weighing of each of the separate fractions. Verification, by means of a lens or microscope, of the degree of obstruction of the…
Aluminium oxide primarily used for the production of aluminium — Determination of an adsorption inde...
Specifies two methods for industrial calcined products. The first, using carbon tetrachloride vapour, is applicable if the density of the material exceeds 3.75 g/ml; the second, using water vapour, is applicable if the density of the material is lower than 3.75 g/ml. The adsorptive power is evaluated by exposure of a previously dried sample to an atmosphere saturated with carbon tetrachloride or…
Paints and varnishes — Determination of viscosity at a high rate of shear
Describes a procedure for determining the viscosity of coating materials and related products at a rate of shear not less than 5000 s-1 and not higher than 20000 s-1. When products are being compared the rate of shear shall be approximately the same. The test shall be made at a closely controlled temperature unless otherwise agreed. The value obtained gives information about the resistance of the…
