GB/T 30771-2024 in English

Analysis of Standard Background and Technology Evolution

GB/T 30771-2024 National Standard for Daily-use Glass Ceramics is a comprehensive revision of the original standard GB/T 30771-2014, mainly optimizing product technical requirements, test methods and inspection rules. The new standard introduces stricter thermal shock resistance requirements and adds mechanical washing resistance performance indicators, reflecting the industry's higher attention to product quality and safety.

With the popularization of household appliances and the improvement of consumer demand for the performance of daily-use ceramics, the new version of the standard pays more attention to the durability and adaptability of the product, especially in the use of microwave ovens and mechanical washing environments. These improvements not only improve product quality, but also provide clearer technical guidance for manufacturers.

Classification and specifications of daily-use glass ceramics

According to GB/T 30771-2024 standard, daily-use glass ceramics are divided into plates, bowls, cups, pots and other utensils according to their uses. The product specifications are divided based on caliber and capacity, and the specific range is as follows:

Technical Requirements and Quality Control

Appearance Quality

The appearance quality of daily-use glass-ceramics directly affects user experience. The standard clearly stipulates the maximum allowable range of defects such as deformation, bubbles, and spots. The following is a comparison of quality indicators of products of different specifications:

Implementation suggestions and practical applications

To ensure that the quality of daily-use glass-ceramic products meets the requirements of GB/T 30771-2024, manufacturers should take the following measures:

• Establish a sound quality management system: Carry out comprehensive control from raw material procurement to production process.
• Strengthen employee training: Ensure that operators are familiar with the technical requirements and test methods of the new standard.
• Optimize detection methods: Equip with advanced instruments and equipment to improve inspection efficiency and accuracy.
• Periodically conduct type inspections: Especially the performance indicators of thermal shock resistance and mechanical washing resistance.
