Foreword

This document was drafted in accordance with the rules provided in GB/T 1.1-2020 Directives for Standardization - Part 1: Rules for the Structure and Drafting of Standardizing Documents.

This document serves as a replacement for GB/T 23436-2009 Cleaning Fluids for Automotive Windshield. In comparison with GB/T 23436-2009, apart from structural adjustments and editorial modifications, the main technical changes are as follows.

a) The terms “original fluids” and “minimum concentration for use” and their definitions are deleted (see Chapter 3 of Version 2009);

b) The technical requirements for the model and freezing point of non-water-repellent products are modified (see Chapter 4; Chapter 4 of Version 2009);

c) The technical requirements and test methods for methanol content are added (see Chapter 4 and Appendix B);

d) The technical requirements and test methods for surface tension and mechanical impurities are added (see Chapter 4);

e) The technical requirements for metal corrosion are modified, and the technical requirements for EPDM rubber test pieces in relation to the impact on rubber are added (see Chapter 4; Chapter 4 of Version 2009);

f) Surface tension, mechanical impurities and water resistance items are added to exit- factory inspection (see 5.3), and the cleaning power and compatibility items at the minimum concentration for use are deleted from exit-factory inspection (see 5.3 of Version 2009);

g) The latest standards and specifications referenced in the test methods, instruments, materials, and reagents for the cleaning power of cleaning fluids are modified (see C.1 and C.2; B.2 and B.3 of Version 2009);

h) The material requirements for metal test pieces in the inspection method for the metal corrosion of cleaning fluids are modified (see E.2.10, D.3.10 of Version 2009);

i) The material requirements for rubber test pieces in the inspection method for the impact of cleaning fluids on rubber are added (see F.2.7);

j) The technical requirements for the test temperature of low-temperature stability in the inspection method for the stability of cleaning fluids are modified (see I.3.2; H.4.2 of Version 2009).
