Specifies a method for the determination of the air content of freshly mixed concrete from observation of the change in volume of concrete with a change in pressure. The method is intended for use with concretes and mortars made with relatively dense aggregates for which the aggregate correction factor can be satisfactorily determined by the technique described in clause 5. It is not applicable…

Gives specifications relating to asbestos-cement pipes and joints intended for use under pressure. Defines certain conditions of manufacture, classification, characteristics, including nominal diamenters, thickness of walls, tolerances etc., and acceptance tests applicable to these products, as well as to special applications.

This second edition cancels and replaces the first edition (1977). Specifies the diameters, thicknesses, tolerances and masses per unit length of fired tubes, including superheater and heat exchanger tubes. It does not apply für tubes according to ISO 6758 and ISO 6759. Tabulates carbon and alloy steel tubes (table 1), austenitic stainless steel tubes (table 2, ferritic and martensitic steel…

Refers to taper dimensions and tolerances for electrode caps, electrode adaptors, electrode holders and similar parts, where the electrode force Fmax, given for diameter d1 in tables 1, 2 and 3 is not exceeded. Establishes dimensions, designation and marking. Cancels and replaces ISO Recommendation R 1089-1969, of which it constitutes a technical revision.

The oil absorption value is required to be compared with the value determined at the same time on an agreed sample of the product. The principle of the method is based on addition of linseed oil from a burette to the test portion. After each addition, rub the oil into the product until conglomerates are formed. Cease the addition of oil when a paste of smooth consistency has been formed. It…
