Foreword
This standard corresponds to ISO 3819. 1985 "Laboratory glassware beaker", and ISO 3819. 1985 is not equivalent degree of consistency.
This standard and ISO 3819. 1985 of the main differences.
--- Increased conical beaker series;
--- Increasing the inner surface of the water, acid and alkali resistance, stress, thermal shock performance indicators;
--- Increase the appearance of the product requirements;
--- Increased test methods, inspection rules, packaging, transport and storage.
This standard replaces GB/T 15724.1-1995 "laboratory glassware beaker" and GB/T 15724.2-1995 "glass laboratory
Instrument cone beaker. "
15724.1 ~ 15724.2-1995 major changes compared to the present standard and GB/T are. an increase in the surface of the water resistance, acid resistance (light
Spectrometry), internal stress, heat shock temperature and product testing rules.
Appendix A of this standard is an informative annex.
The standard proposed by China National Light Industry Council.
This standard by National Instrument Standardization Technical Committee on Glass (SAC/TC178) centralized.
This standard was drafted. Beijing Glass Instrument Factory, glass National Light Industry Product Quality Supervision and Inspection Center.
The main drafters of this standard. Wu Wenling, Yuan Shouju, Du Yuhai, Yuan Chunmei.
This standard replaces the standards previously issued as follows.
--- GB/T 15724.1-1995;
--- GB/T 15724.2-1995.
