Preface
This document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents"
Drafting:
This document replaces GB/T 15622-2005 "Hydraulic Cylinder Test Methods": Compared with GB/T 15622-2005, except for structural adjustments and compilation
In addition to editorial changes, the main technical changes are as follows:
a) The test device requirements and test schematic diagram are deleted (see 5:1 of the:2005 edition);
b) The test conditions have been changed (see Chapter 6, Chapter 5 of the:2005 edition);
c) The test items and requirements have been changed (see Chapter 7 ~ Chapter 10, Chapter 6 ~ Chapter 8 of the:2005 edition);
d) The requirement for test reports has been deleted (see Chapter 9 of the:2005 edition):
This document is modified to adopt ISO 10100:2020 "Acceptance Test of Hydraulic Transmission Cylinder":
The technical differences between this document and ISO 10100:2020 and their reasons are as follows:
---Replaced ISO 5598 (see Chapter 3) with normatively quoted GB/T 17446 to adapt to my country's technical conditions and improve operability:
work nature;
---Replaced ISO 6743-4 and ISO 7745 (see 6:1) with normatively cited GB/T 7631:2 and GB/T 16898 to suit our needs
adapt to the country’s technical conditions to improve operability;
---Replaced ISO 4406 (see 6:2:2) with normatively cited GB/T 14039 to adapt to my country's technical conditions and improve operability
work nature;
---Changed the test setting requirements for friction test (see 10:2, 10:2 of ISO 10100:2020) to adapt to my country's technical conditions
parts to improve operability:
The following editorial changes have been made to this document:
---Change the name of the standard to "Hydraulic Cylinder Test Method";
---Deleted the footnote of Table 1;
---Changed some symbols;
---Change the solid particle pollution level to three-stage;
