The DIN Standards corresponding to the International Standards referred to in this document are as follows: ISO 3170 DIN EN ISO 3170, DIN 51750-1, DIN 51750-2 ISO 3585 DIN ISO 3585 Amendments This standard differs from DIN 51352-1:1985-08 as follows: a) the standard has been prepared on
9、 the basis of DIN 51352-1:1985-08, thus specifying the same subject of standardization. In accordance with the DIN Guidelines, DIN 51352-1:1985-08 must therefore be withdrawn; b) normative references have been updated.

11、5 Petroleum-based lubricating oils Aging characteristics Determination of change in Conradson carbon residue after oxidation WARNING - The use of this International Standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problem
12、s associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1 Scope This International Standard specifies a procedure for determination of the ageing char
13、acteristics of petroleum-based lubricating oils. It is applicable to those oils which have an evaporation loss of less than 15 % mass fraction, as determined by the procedure specified in 9.3 of this standard. 2 Normative references The following standards contain provisions which, through reference
14、 in this text, constitute provisions of this International Standard. At the time of publi- cation, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the mo
15、st re- cent editions of the standards indicated below. Members of IEC and IS0 maintain registers of cur- rently valid International Standards. IS0 3170:1988, Petroleum liquids - Manual sampling. IS0 3585:1991, Borosilicate glass 3.3 - Properties. IS0 6615: 1993, Petroleum products - Determination of
16、 carbon residue - Conradson method. 3 Definition For the purposes of this International Standard, the following definition applies. 3.1 ageing characteristics: Characteristics of a petroleum-based lubricating oil as determined by the increase in the Conradson carbon residue of the oil aged in accord
17、ance with this International Standard in comparison to that of the same non-aged oil. 4 Principle The oil sample to be tested is aged for two 6-h peri- ods at a temperature of 200 “C while air is passed through the oil. The value of the Conradson carbon residue of the aged sample is determined accor
18、ding to IS0 6615. The Conradson carbon residue of the non-aged oil, also determined according to IS0 6615, is subtracted from this value. The increase in the value of the carbon residue of the aged oil over that of the non-aged oil is reported as the result. Under no circumstance may the procedure s
19、pecified in IS0 6615 be modified, or any other procedure substituted for this procedure. 5 Apparatus 5.1 Testing apparatus, consisting of an ageing vessel and a holder with an air inlet tube and an air outlet tube (figure I), all parts being manufactured from borosilicate glass in accordance with IS

The air inlet tube shall be manufactured from 7 mm x 1 mm borosilicate glass pipe in accordance with IS0 3585, and sealed into the holder as illus- trated in figure 1. The air inlet tube shall be mounted in the centre of the holder and
22、 its lower end cut square. The length of the air inlet tube shall be such that, with the holder securely in place in the ageing vessel, its lower end is 1 mm b) a reference to this International Standard; c) the results of the test (see 10.2); d) any deviation, by agreement or otherwise, from the pr
