Introduction
GB/T 39141 aims to provide a basis for design, production and acceptance for manufacturers and users of inorganic and sapphire watch glasses.
GB/T 39141 is proposed to consist of 4 parts.
-- Part 1.Dimensions and tolerances. The purpose is to enhance the interchangeability of round flat inorganic and sapphire watch glasses.
-- Part 2.Fittings to the watch case by gluing or sealing rings. The purpose is to standardize the fittings to the watch case by gluing or sealing rings.
Dimensional requirements for circular inorganic and sapphire watch glass contact surfaces.
-- Part 3.Qualitative standards and test methods. Aims to enhance the performance quality of inorganic and sapphire watch glasses.
-- Part 4.Anti-reflection treatment. The purpose is to ensure the performance of anti-reflection films on inorganic and sapphire watch glasses.
