Polyethylene terephthalate(PET) beer bottle
1 Scope
This document defines the terms and definitions of polyethylene terephthalate (PET) beer bottles, specifies the product classification, requirements, inspection rules, as well as marking, packaging, transportation and storage, and describes the corresponding test methods.
This document applies to beer bottles produced by injection molding, stretch molding and blow molding processes with bottle-grade polyethylene terephthalate resin as the main raw material.
This document does not apply to polyethylene terephthalate beer bottles with an inner wall carbon coating.

6 Testing methods
6.1 Standard environment for sample conditioning and testing
Condition samples in the standard environment (23±2)℃ specified in GB/T 2918 for no less than 2 hours, and conduct tests under this condition.
6.2 Appearance and bottle mouth dimension deviation
Visually inspect the appearance under natural light or equivalent light source.
Measure the maximum and minimum dimensions of the bottle mouth with measuring tools, calculate the difference from the standard value, and the result shall be accurate to 0.01mm.
6.3 Height deviation
Measure the maximum vertical height of the bottle with a measuring tool of 0.02mm accuracy, and calculate the height deviation according to Formula (1).
6.4 Capacity deviation
Take 6 sample bottles, weigh the mass of each empty bottle separately, then fill with water to the fill point, weigh the total mass of the bottle and water (accurate to 0.1g), measure the water temperature, find the density of water from Annex A, and calculate the bottle capacity according to Formula (2).
6.5 Physical properties
6.5.1 Sealing performance
Take 6 sample bottles, fill with carbonic acid aqueous solution (23±2)℃ with carbon dioxide content of (0.54±0.02)% (mass fraction) [equivalent to 3.0±0.1 times volume, prepared in accordance with Annex B] to the fill point, seal quickly with caps, place horizontally at (23±2)℃ for 4 hours, and observe whether there is liquid leakage at the bottle mouth.
6.5.2 Vertical compressive load performance
Take 6 sample bottles, place them in an environment of (23±2)℃ for more than 2 hours, place the bottles vertically on a universal testing machine, apply vertical pressure at a constant speed of 500mm/min, record the initial maximum load the bottle can bear (accurate to 1N), and calculate the arithmetic mean of the test results.
6.5.3 Drop performance
Take 6 sample bottles, fill with carbonic acid aqueous solution (23±2)℃ with carbon dioxide content of (0.54±0.02)% (mass fraction) [equivalent to 3.0±0.1 times volume, prepared in accordance with Annex B] to the fill point, seal quickly with caps, let the bottles fall freely with the bottle mouth upward from a height of 2.0m (bottle bottom to the ground) onto a flat concrete floor or equivalent surface, and check and record whether there is leakage.
