What is ISO 14368-4 about?
ISO 14368-4 discusses anti-reflective treatment for mineral and sapphire watch glasses ISO 14368-4 specifies the terms and definitions, the test methods, and the evaluation of results of watch glasses with anti-reflective treatments.
Note: ISO 14368-4 is applicable to sapphire watch glasses with anti-reflective treatments, and ISO 14368-4 can also be used as a reference for mineral watch-glasses with anti-reflective treatments.
Who is ISO 14368-4 for?
ISO 14368-4 on anti-reflective treatment for mineral and sapphire watch glasses is useful for:
- Watch glasses manufacturers and suppliers
- Laboratories
- Watch manufacturers
Why should you use ISO 14368-4?
Anti-reflective treatments are widely used in watch glasses. ISO 14368-4 specifies anti-reflective treatments that are used to improve the legibility of the watch dial by reducing light reflected from the watch glasses.
When customers wear watches, the watches go through temperature differences, rust, scratches, sunlight, and many other environmental conditions. The properties of the anti-reflective treatment can directly affect the appearance of the watch glasses and the legibility of the dial; Therefore, the objective of ISO 14368-4 is to clarify test methods and evaluations for anti-reflective treatment.
ISO 14368-4 provides test methods and the evaluation of results of watch glasses with anti-reflective treatments, which helps to manufacture mineral and sapphire watch glasses and watches.
