Область применения
This standard applies to glass beer bottles used for containing beer. It categorizes bottles into recycle beer bottles (including new and used) and non-recycle bottles (one-time use). It is mandatory for all manufacturers producing or supplying glass containers for the Chinese beer industry. The standard does not apply to containers made of other materials such as metal or plastic.
Технические требования
GB 4544-2020 specifies comprehensive physical and chemical requirements for beer bottles. It mandates specific thresholds for vertical load strength, internal pressure resistance, and impact resistance, which are differentiated based on the bottle's brimful capacity and whether it is a new, used, or one-time-use bottle. Manufacturers must ensure their products meet these tiered performance limits to guarantee safety during filling and transportation. The standard also defines strict dimensional tolerances for brimful capacity, bottle height, and outer diameter. For recyclable bottles, minimum thickness requirements for the bottle body and bottom are specified based on the nominal outer diameter, and the thickness ratio for both the body and bottom must not exceed 2:1. Crown cap dimensions must comply with referenced standards like GB/T 37855 or GB/T 37856. Furthermore, the standard outlines detailed appearance requirements to eliminate critical defects. Bottles must be free from cracks, broken bubbles, and stones on the sealing surface. Specific limits are set for the size and quantity of acceptable stones and bubbles in non-critical areas to ensure structural integrity and aesthetic quality. The bottom supporting surface must also feature knurling.
Методы испытаний
Testing procedures are rigorously defined to verify compliance. Vertical load strength is tested according to GB/T 22934 with a specific loading speed. Internal pressure resistance and thermal shock resistance are evaluated using GB/T 4546 and GB/T 4547 respectively. Impact resistance is measured via GB/T 6552, targeting the middle of the bottle body while avoiding the seam. Internal stress and inner surface water resistance are tested per GB/T 4545 and GB/T 4548. Dimensional attributes are measured using precision instruments like vernier calipers and thickness gauges.
Частые вопросы
What are the main updates in GB 4544-2020 compared to the 1996 version?
The 2020 version removes the grading requirements for physical and chemical properties and the two-year recycling limit. It introduces vertical load strength testing, classifies bottles into one-time use and recyclable categories with distinct performance indicators, and mandates the "NR" mark for non-recyclable bottles.
What specific markings are required on beer bottles under this standard?
Every beer bottle must have a "B" mark within 20mm above the bottom to indicate it is a dedicated beer bottle, along with the manufacturer's mark and production year/quarter. Non-recyclable (one-time use) bottles must additionally be marked with "NR" at the root position.
Are there specific packaging requirements for beer bottles?
Yes, appropriate packaging such as pallets, plastic crates, or cartons must be used. The use of sacks or strapping that could degrade the quality of the bottles is strictly prohibited. Packaging must keep the product clean and prevent breakage.
