8、. This standard is intended to assist users concerned with the selection of lubricants for industrial equipment, machine designers, lubricant suppliers, and those responsible for the use and maintenance of equipment. The requirements specified are those essential for a lubricant, namely viscosity in

9、 terms of the classification in BS 4231, viscosity/temperature characteristics, flashpoint, pour point and freedom from acidic constituents. An additional requirement is given for demulsibility, i.e. the ability of an oil to permit separation of water, which is important in certain applications wher

10、e water is liable to occur in service. This British Standard specifies requirements for two types of straight mineral lubricating oils, each containing 13 viscosity grades. One type of oil is intended primarily for use in total loss systems, i.e. those in which the oil is run to waste after performi

11、ng its function. The other type of oil is intended for use in circulating systems in which the oils are retained or recirculated. A number of preferred viscosity grades are indicated in an attempt to rationalize oil stocks. It is hoped that equipment manufacturers will select these preferred viscosi

12、ty grades when designing new equipment and will recommend their use, thus providing a progressive reduction in the number of grades required. This British Standard does not cover lubricating oils containing additives which enhance the properties of the lubricant. Pour point depressants are, however,

13、 permitted to ensure compliance of the oil with this standard. This edition introduces the current editorial format and updates the methods of test, but does not reflect a full review or revision of BS 4475:1991, which will be undertaken in due course. A British Standard does not purport to include

14、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. Summary of pages This document comprises a front cover, an inside front cover, pages i a

23、urposes of this British Standard, all sampling shall be carried out in accordance with the relevant procedures and precautions described in BS EN ISO 3170. 4 Composition The oils shall be pure mineral oils free from additives, except that when the pure mineral oils cannot comply with the pour point

24、requirement (see Table 1), it is permissible to add a pour point depressant. On visual inspection, the oils shall be clear and free from water, suspended matter, dirt and sediment. NOTE Oils of the same quality level i.e. bearing the same designation (ISO-L-AN or CS conforming to this standard are c

25、ompatible with one another and may be mixed in any proportion.2 BSI 01-2001 BS 4475:2000 1) Marking BS 4475:2000 on or in relation to a product represents a manufacturers declaration of conformity, i.e. a claim by or on behalf of the manufacturer that the product meets the requirements of the standa

26、rd. The accuracy of the claim is solely the claimants responsibility. Such a declaration is not to be confused with third-party certification of conformity. 5 Requirements 5.1 General When tested in accordance with the methods shown in Tables 1 or 2 as appropriate, the oils shall conform to the limi

27、ting requirements given in the relevant table for the grade concerned. 5.2 Grade designations 5.2.1 General Oils supplied to this standard shall be designated type (ISO-L-AN or CS) and viscosity grade number. 5.2.2 Type designation Oils for total loss systems (see Table 1) shall be designated accord

28、ing to the classification in BS 6413-1 for defined mineral oils, i.e. ISO-L-AN. Oils for circulating systems (see Table 2) shall be designated CS. 5.2.3 Viscosity grade All types of oil shall additionally be designated according to their viscosity in accordance with the ISO viscosity classification

29、given in BS 4231, i.e. a number corresponding to the mid-point kinematic viscosity at 408C, e.g. ISO VG 150. NOTE The viscosity designation may be abbreviated in the full designation, e.g. CS 150. 5.3 Demulsibility If required, the demulsification number for a circulating system oil shall be determi

30、ned in accordance with BS 2000-412. If an oil conforming to the additional requirement for demulsibility is specified, the grade designation shall be identified by the addition of the letter X following the viscosity number. For viscosity grades up to and including CS 100, the limit shall be 40/40/0

31、 in 5 min. For viscosity grades CS 150 to CS 1 000, the limit shall be 40/40/0 in 20 min. 5.4 Precision and interpretation of results Most of the methods given in Tables 1 and 2 contain a statement of the precision, i.e. the repeatability and reproducibility to be expected from them but, in cases of

32、 dispute, the procedure described in BS EN ISO 4259, which uses precision data in the interpretation of the results, shall be used. 6 Packaging and marking The oils shall be supplied in bulk or in clean, sound and dry containers as agreed between the purchaser and supplier. Each container shall be l

33、egibly and durably marked with the following: a) the number and date of this British Standard, i.e. BS 4475:2000 1) ; b) the type and grade designation, e.g. ISO-L-AN 150, CS 68; c) the name or mark of the supplier or vendor and the batch or consignment number.
