This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents"
drafting:
This document replaces GB/T 269-1991 "Measurement of Penetration of Lubricating Grease and Petroleum Grease": Compared with GB/T 269-1991, except for the structure
In addition to adjustments and editorial changes, the main technical changes are as follows:
a) Changed the maximum measurable cone penetration value from "620 units" to "500 units" (see Chapter 5,:1991 edition
Chapter 1);
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":

3 Terms and Definitions
The 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:
