This document is part 5 of GB/T 10810 "Spectacle lenses". GB/T 10810 has published the following parts. --- Part 1.Single focal and multifocal; ---Part 2.Gradual zoom; --- Part 3.Transmittance test method; --- Part 4.Test methods for anti-reflection coatings; --- Part 5.Surface wear test method. This document replaces GB 10810.5-2012 "Spectacle lenses - Part 5.Requirements for lens surface wear resistance" and is compatible with GB 10810.5-2012 Compared with the previous version, in addition to structural adjustments and editorial changes, the main technical changes are as follows. a) The wear resistance requirements for the lens surface (convex surface) have been deleted (see Chapter 4 of the.2012 edition); b) Added the falling sand test method (see Chapter 6). This document is modified from ISO 8980-5.2005 “Ophthalmic optics – Uncut spectacle lenses – Part 5.Spectacle lenses with indicated surface resistance to abrasion” Minimum Requirements for Films. This document has made the following structural adjustments compared to ISO 8980-5.2005. --- Deleted Chapter 4 of ISO 8980-5.2005; --- Move the content about test environment temperature in 5.2 of ISO 8980-5.2005 to 4.1 "Test conditions", and the content about sample cleaning Content moved to 4.4 “Test Procedures”; --- Adjust Figure A.1 in Appendix A and Figure C.1 in Appendix C of ISO 8980-5.2005 to Figure 1 and Figure 2 in 4.2.1; --- Move Figures 1 and 2 in 5.1.5 of ISO 8980-5.2005 to Appendix A; --- Deleted Appendix B of ISO 8980-5.2005. The technical differences between this document and ISO 8980-5.2005 and their reasons are as follows. --- Replaced ISO 13666 and ISO 8980-4 with the normative reference GB/T 26397, and deleted the term and definition of "wear-resistant" (see Chapter 3) to adapt to my country's technical conditions and increase operability; --- Replaced ISO 48.2010 (see 4.2.2) with the normative reference GB/T 6031 to adapt to my country's technical conditions and increase the Operability; --- Added surface enhanced wear test and falling sand test methods (see Chapter 5 and Chapter 6) to enrich the test methods and increase the test The selectivity of the method; --- Added a quantitative percentage "haze value" to characterize abrasion resistance (see 5.6) to increase the operability of the test method; --- Added a simplified diagram of steel wool and friction meter (see Appendix B) to improve intuitiveness and facilitate viewing and use. The following editorial changes were made to this document. --- In order to coordinate with the existing standards in my country, the name of the standard is changed to "Spectacle Lenses Part 5.Surface Abrasion Test Method"; --- Deleted the informative appendix "Verification of test sites" (see Appendix B of ISO 8980-5.2005).

They are an important part of glasses and can meet the needs of users in different occasions. The visual needs of people are of great significance to their vision health. GB/T 10810 "Spectacle Lenses" aims to standardize the production and use of lenses and improve The quality and safety of the lenses. GB/T 10810, as a recommended national standard supporting the mandatory national standards, consists of five parts. --- Part 1.Monofocal and multifocal lenses. The purpose is to ensure the quality of monofocal and multifocal lenses by standardizing the requirements and test methods. Price criteria. --- Part 2.Progressive lenses. The purpose is to ensure the quality evaluation criteria by standardizing the requirements and test methods for progressive lenses. --- Part 3.Transmittance test method. The purpose is to establish the test method for the transmittance performance of lenses and to establish its quality evaluation criteria. --- Part 4.Test methods for anti-reflection coatings. The purpose is to establish test methods for anti-reflection coatings on lenses and to establish quality evaluation standards. Guidelines. --- Part 5.Surface abrasion test methods. The purpose is to establish multiple abrasion test methods for lenses and establish their quality evaluation criteria. Glasses lenses Part 5.Test methods for surface wear resistance1 ScopeThis document describes the instruments, samples, test procedures and test data processing for the surface wear resistance test of lenses. This document applies to the test of the wear resistance of lens surfaces.2 Normative referencesThe contents of the following documents constitute essential clauses of this document through normative references in this document.

There is a spring in the slide bar that maintains a pressure of 5N±1N. The end of the rod can be fixed with a rubber head. During the test, the friction tool is kept perpendicular to the sample surface, and the slide bar does not move beyond the mark or the slide bar scale line. The external structure of the friction tool is shown in Figure 1. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 10810.5-2025_English be delivered?Answer: Upon your order, we will start to translate GB/T 10810.5-2025_English as soon as possible, and keep you informed of the progress.
