Specifies the charpy impact method using U-notch test pieces. Determines the impact strength of steel by breaking by one blow from a swinging pendulum, under conditions defined hereafter, a test piece resting on two supports and determining the energy absorbed.
Steel, non-alloy and low-alloy — Determination of depth of decarburization
Defines carburization and specifies three methods of measuring the depth of decarburization of non-alloy and low-alloy steels (micrographic method, method of measuring the micro-hardness and methods of determination of carbon content).
Cryolite, natural and artificial — Determination of silica content — Reduced molybdosilicate spectro...
Specifies methods of test for natural and synthetic materials having a molar ratio sodium fluoride/aluminium trifluoride between 3 and 1,7 approximately. The method is applicable to products the phosphorus pentoxide content of which does not exceed 0,02 % (m/m). The procedure consists in alkaline fusion of a test portion by means of a mixture of sodium carbonate and boric acid. Dissolution of the…
Steel products for pressure purposes — Derivation and verification of elevated temperature propertie...
Defines a method for deriving minimum elevated temperature proof stress values for inclusion in International Standards for austenitic steel products. Defines further a verification procedure which may be used by a manufacturer as an alternative to hot-testing for satisfying the purchaser that his product meets the specified minimum elevated temperature proof stress values.
Paints and varnishes — Determination of light fastness of paints for interior use
Specifies a method for operating laboratory equment. It does not attempt to define either the minimum accetable standard or the precise techniques to be adopted for the test; these are to be the subject of agreement between the interested parties. The posible forms which the test requirement may take are the following: The test material shall be at least as ligthfast as a specified wool scale…
This method is applicable to the zinc alloys defined in ISO 301. It is suitable for the determination of magnesium contents between 0,01 and 0,08 %. ISO 3750 specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report.
Aluminium oxide primarily used for the production of aluminium — Determination of silica content — R...
The method is applicable to products having a silica content between 0.005 % (m/m) and 0.025 % (m/m) provided that the content of phosphorus pentoxide plus vanadium pentoxide does not exceed 0.02 % (m/m). The principle of the method is based on the formation of oxidized molybdosilicate (yellow) under well-defined conditions of acidity, concentration of reagents, temperature and time. Selective…
Stencils for duplicators - Minimum overprint and attachment features
Defines the dimensions of the working area of dublicating stencils intended for use with paper of sizes up to and including A4 (210 mm x 297 mm). Lays down: the minimum information printed on the face of the stencil and the prefered information relating to markings for the A series of paper sizes; the attachment features of stencils according to those specified in ISO 2132.
