9、is Part of BS 6413 has been prepared under the direction of the Petroleum Standards Committee in order to provide a classification scheme for lubricants, industrial oils and related products. It is identical with ISO 6743-7:1986 “Lubricants, industrial oils and related products (class L) Classificat

10、ion Part 7: Family M (Metalworking)”, published by the International Organization for Standardization (ISO). ISO 6743-7 was prepared as a result of discussions in Subcommittee 4, Classifications and specifications, of Technical Committee 28, Petroleum products and lubricants, in which the UK has par

11、ticipated. A general classification of petroleum products prepared in ISO/TC 28 has allocated class L to lubricants. BS 6413-0 details the subdivision of class L into families of products, to each of which a code letter is allocated. This Part provides a detailed classification within family M of cl

12、ass L. Further Parts of the International Standard will provide a detailed classification within other families of class L and will be published as further Parts of BS 6413. Terminology and conventions. The text of the International Standard has been accepted as suitable for publication as a British

13、 Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to the following. Whenever the words “part of ISO 6743” appear, referring to this standard, they should be read as ”Part of BS 6413“. A British

14、Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cross-references International Standard Correspondi

17、1 Scope and field of application This part of ISO 6743 establishes the detailed classification of family M (Metalworking) which belongs to the class L (Lubricants, industrial oils and related products). It should be read in conjunction with ISO 6743-0. To avoid any misunderstanding and to clarify th

18、e text, the following annexes are included: Annex A: definitions of certain words or terms used in this classification; Annex B: distribution of categories of products by field of application in tabular form; Annex C: distribution of categories of products, in relation to their constitution and prop

19、erties, in tabular form. 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 of family M has been establis

20、hed by defining the categories of products required for the main applications of this family. 3.2 Each category is designated by a symbol consisting of a group of three letters, which together constitute a code. NOTEThe first letter of the category (M) identifies the family of the product considered

21、 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 grades according to ISO 3448. 3.3 In this classification system, products are designated in a uniform manner. For example, a particular pro

22、duct may be designated in the complete form, i.e: ISO-L-MHA 32, or in an abbreviated form, i.e.: L-MHA 32, the number indicating the class of viscosity according to ISO3448. 4 Classification of lubricants for metalworking (family M) See Table 1.BS6413-7:1988 2 BSI 08-1999 Table 1 Classification of l

32、 part of the Standard.) A.1 fluid A liquid substance of mineral, animal, vegetable or synthetic origin in any proportion. Metalworking fluid may contain biocides. A.2 concentrate A blend of suitable emulsifying agents and additives such as antirust, antimicrobial and others with refined mineral oils

33、 in the case of aqueous emulsions, or suitable chemical products in the case of aqueous solutions, which are later diluted for use. For particular applications, these concentrates may be applied undiluted. A.3 chemically active lubricant A fluid which is corrosive to copper and its alloys, as oppose

34、d to “chemically non-active lubricants”, which are not. Methods for the evaluation of this characteristic will be defined later. A.4 containing a filler Containing additives in a solid form, such as solid lubricants (graphite, molybdenum disulfide), metallic salts, metallic soaps, metallic oxides, e

35、tc., to enhance lubricating properties when contact pressures are high (forming, and hot operations in particular). Annex B Distribution of categories of family M products according to field of application (This annex does not form an integral part of the Standard.) Table 2 constitutes a general and

36、 non-exhaustive example of an application guide for the main classes of metalworking fluids. Professional users will be able to refer to it to obtain an overall view of the principal families of products which are in common use. This table may equally serve as a basis for establishing specifications

37、 according to areas of applications.
