9、d as a result of discussion in Subcommittee 4, Classifications and specifications, of Technical Committee 28, Petroleum products and lubricants, in which the UK participated.

Some terminology and certain conventions are not identical with those used in British Standards; attention

12、is drawn especially to the following. Wherever the words “part of ISO 6743” appear, referring to this standard, they should be read as “Part of BS 6413”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their co

This will be indicated in the amendment table on the inside front cover.BS6413-8:1988 BSI 08-1999 1 1 Scope and field of application This part of ISO 6743 establishes the detailed classification of family R (Temporary protection against

16、corrosion), which belongs to class L (Lubricants, industrial oils and related products). It should be read in conjunction with ISO 6743-0. This classification applies to categories of products which are assigned to ensure temporary protection against corrosion. It includes only those products the ma

17、in function of which is to ensure temporary protection, the word “temporary” being relevant not to time-limit product efficiency but to the capacity for removal of the product after a certain time. This classification excludes products that are applied for other purposes but also ensure temporary pr

18、otection. Vapour-phase inhibitors and other chemical products that differ from petroleum products in behaviour are also excluded. This classification applies to protection of both bare metals and coated metals (painted metallic surfaces, car bodies, etc.). In addition, corrosion is regarded as deter

19、ioration of surfaces of all metals, not only ferrous. 2 References ISO 3448, Industrial liquid lubricants ISO viscosity classification. ISO 6743-0, Lubricants, industrial oils and related products (Class L) Classification Part0:General. 3 Explanation of symbols used 3.1 This detailed classification

20、of family R has been established by defining the categories of products required for the main applications of temporary protection against corrosion, in relation with duty conditions (see the Annex) and nature of the protecting film. 3.2 Each category is designated by a symbol consisting of a group

21、of letters, which together constitute a code. NOTEThe first letter of the category (R) identifies the family of the product considered but any following letters taken separately have no significance on their own. The designation of each category can be supplemented by the addition of viscosity grade

22、s according to ISO 3448. 3.3 In this classification system, products are designated in a uniform manner. For example, a particular product may be designated in complete form, i.e: ISO-L-RE, or in an abbreviated form, i.e.:L-RE. 4 Detailed classification of products for temporary protection against c
