Spices and condiments — Preparation of a ground sample for analysis
Basis for this method is the laboratory sample obtained by the method specified in ISO 948. The principle of determination consists in grinding the laboratory sample, which has been previously mixed, to obtain particles of the size specified in the International Standard appropriate to the spice or condiment concerned or, if not so specified, to obtain particles of size approximately 1 mm.
This second edition cancels and replaces the first edition (1975). Specifies the dimensions, tolerances and generally used grades of non-alloy, low alloy and alloy steels for bends /type 2D (90 and 180 ) and 3D (45 , 90 and 180 )/, concentric and eccentric reducers, tees, caps and ends with quality requirements as used for piping work.
Woodworking machines — Diameters of spindles for receiving circular sawblades
Lays down the diameters of the spindles receiving circular sawblades for wood. The diameters given in a table conform to the dimensions specified in ISO 2935.
Corrosion of metals and alloys — Determination of dezincification resistance of brass
The method applies to brass exposed to frech or saline waters. May be used for control or research purposes, but the field of application is not specified. The method consists of exposure of test pieces to copper(II) chloride solution followed by microscopic examination.
The requirements specify a series of capacities from 100 ml to 2000 ml. The construction with material, shape, radius of curvature of base and the vacuum connection are illustrated. The dimensions are tabled and the most important sections of the flask are drawn. The annex specify hydraulic external pressure tests.
