Surface and its parameters. The principal factors that are known to influence this performance are a the presence of rust and mill scale; b the presence of surface contaminants, including salts, dust, oils and greases; c the surface profile.

The many abrasive blast-cleaning procedures in common use are described in ISO Comparators require careful handling.

Annex ZA normative Normative references to international publications with their relevant European publications This European Standard incorporates by dated or undated reference, provisions from other publications.
Various BSI electronic information services are also available which give details on all its products and services. The visual assessment of the comparator shall not be inferior to preparation grade Sa 2 ” of ISO ISOTests for the assessment of surface cleanliness. If these details are to be used for any other purpose than implementation then the prior written permission of BSI must be obtained. Your basket is empty. It is the constant aim of BSI to improve the quality of our products and services.
The determination can be carried out on a representative section of the blast-cleaned surface or, if direct observation of the surface is not feasible, on a replica of the surface. Find Similar Items This product falls into the following categories.
