b) Added the terms "cone penetration" and "cone penetration" (see 3:1, 3:2); c) The chapter "Classifications, Processes and Limitations" has been added (see Chapter 5); d) The size tolerance of the cone has been changed (see Figure 2, Figure 3, Figure 4, Figure 5, Figure 2, Figure 3, Figure 4, Figure 5 of the:1991 edition); e) Changed the size of the 1/2 scale cone grease worker A from "φ38:5mm" to "φ36:5mm" (see Figure 7,:1991 version of Figure 7); f) Changed the size of the grease cutter blade from "68mm×185mm" to "65mm×185mm" (see Figure 9, Figure 9 of the:1991 edition); g) Added the chapter "Sampling" (see Chapter 7); h) Added 1/2 and 1/4 scale cone method "general rules" (see 9:1); i) The precision of full-scale cone penetration has been changed (see Table 1, Table 1 of the:1991 edition); j) The chapter "Test Report" has been added (see Chapter 14): This document is modified to adopt ISO 2137:2020 "Measurement of Penetration of Lubricating Grease and Petroleum Grease": The technical differences between this document and ISO 2137:2020 and their reasons are as follows: ---Replace ISO 23572 (see Chapter 7) with the normatively quoted SH/T 0229 to adapt to my country's technical conditions and increase operability Workability (see Chapter 2): This document has the following editorial changes compared with ISO 2137:2020: --- Added an informative reference to GB/T 7631:8-1990 in Chapter 5, and added "References": Please note that some contents of this document may refer to patents: The issuing agency of this document assumes no responsibility for identifying patents: This document is proposed and managed by the National Petroleum Products and Lubricants Standardization Technical Committee (SAC/TC280): This document is drafted by: Sinopec Petrochemical Research Institute: The main drafter of this document: Jiang Liang: The release status of previous versions of this document and the documents it replaces are as follows: ---GB 269-1985, GB 5017-1985; --- Merge GB 269-1985 and GB 5017-1985 into GB/T 269-1991; --- This is the third revision: Test method for penetration of lubricating grease and petroleum grease Caution---The use of this document may involve some hazardous materials, equipment and operations, and this document does not point out all possible safety hazards: full question: It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations:1 ScopeThis document describes a method for determining the consistency of lubricating greases and petroleum greases by the penetration method: This document applies to grease and petroleum grease (Vaseline):2 Normative referencesThe contents of the following documents constitute the essential provisions of this document through normative references in the text: Among them, dated references For documents, only the version corresponding to the date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to this document: SH/T 0229 Sampling method for solid and semi-solid petroleum products3 Terms and DefinitionsThe following terms and definitions apply to this document: 3:1 Penetration The depth to which a standard object, cone or needle penetrates the test part under specified conditions of time, temperature and load: 3:2 cone penetration conepenetration The depth to which the cone penetrates the specimen under specified conditions of load, time and temperature: Note: 1 unit of cone penetration = 0:1mm: 3:3 working Shearing motion of a grease worker: 3:4 unworked penetration unworkedpenetration With as little agitation as possible, the sample is transferred from the sample container to the worker cup to determine the cone penetration (3:2): 3:5 Worked penetration workedpenetration The cone penetration (3:2) measured after the sample is reciprocated in the grease worker for a specified number of times: 3:6 The cone penetration (3:2) measured after the sample has been reciprocated more than the specified number of times in the grease worker: ...... |
