GB/T 35598 - 2017 Focused Borosilicate Glass Pressing Heat Resistant Appliances. The standard specifies the material requirements of the appliance to ensure the use of high-quality borosilicate Glass. Specify the dimensional deviation and Appearance mass of the appliance, such as bubbles, scratches, etc. Specify the heat resistance indicators in detail, such as the temperature range and thermal Impact test requirements. Through these standards, ensure the safe use of such appliances in high temperature environments, provide a basis for manufacturers to control the mass of products, meet the needs of catering, laboratories and other fields for heat-resistant Glass appliances, and improve user experience.
