GB/T 37851-2019Glass containers - Standard tolerances for flaconnage (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the redrafting method to modify the ISO 12818.2013 "standard tolerance for glass packaging small mouth bottles".

This standard has been structurally adjusted compared to ISO 12818.2013, and the scope and product group bottles have been combined and deleted.

Chapter 2 of the ISO 12818.2013 "Product Group Bottles and Other Glass Containers".

The technical differences between this standard and ISO 12818.2013 are as follows.

--- Range chapter removes the type of glass bottle that is not applicable in this standard.

This standard has made the following editorial changes.

--- Added a description of the symbols in the formula;

--- Modified the note in Figure 3.

This standard was proposed by the China Light Industry Association.

This standard is under the jurisdiction of the National Daily Glass Standardization Technical Committee (SAC/TC377).

This standard was drafted. Donghua University, National Eyeglass Glass Enamel Product Quality Supervision and Inspection Center, Shanghai Glasses Glass Enamel Products
