This document specifies the general conditions and procedures which need to be observed when testing coated test specimens in constant condensation-water atmospheres or in alternating condensation-water atmospheres, in order to ensure that the results of tests carried out in different laboratories are reproducible.

NOTE The shape and preparation of the test specimens, the duration of the test and the assessment of the test results are not covered in this document.

This document specifies an instrumental method for determining the turbidity of clear liquids. It is applicable to resins and resin solutions, solvents, clear coating materials, monomers and any other liquids where clarity is specified. The measurement of the turbidity of liquids can be carried out visually or by instrument, but visual methods can be subjective. This method measures instrumentally the scattering of light by the insoluble matter in a liquid and therefore gives an objective determination of turbidity. Turbidity in liquids is caused by the presence of undissolved matter (i.e. non-settling flocculation, gels or other suspended matter such as particles or droplets). In the case of finely dispersed undissolved matter, the turbidity may be determined by measuring the intensity of the light which is scattered by the particles when a beam of light is passed through the liquid.

This document describes a classification of non-metallic blast-cleaning abrasives for the preparation of steel substrates before application of paints and related products. It specifies the characteristics which are required for the complete designation of such abrasives. This document applies to abrasives supplied in the "new" or unused condition only. It does not apply to abrasives either during or after use. NOTE Although this document has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504‑2.
