Furthermore, these regulations also specify the inspection methods and standards, the judgment criteria for inspection results, and the requirements for inspection records and reports. These inspection items and regulations aim to ensure the quality and safety of glass bottles and provide reliable technical support for the production and use of glass bottles.

Translation: The inspection and testing standards for glass bottles may vary in different countries and regions. Here are some relevant standards and specific details for some countries or regions:

1. European Union (EU): The EU mainly refers to international standards such as ISO 719 and ISO 718 for the inspection and testing of glass bottles. In addition, the EU has also developed some standards for specific types of glass bottles, such as the Pharmaceutical Glass Standards (EP), Wine Bottle Standards (DIN 228), Food Glass Bottle Standards (DIN 6120), etc.
2. United States: The US Food and Drug Administration (FDA) has issued a series of standards for glass bottles, including requirements for production, packaging, labeling, storage, and transportation. In addition, some private organizations in the US have developed testing standards for glass bottles, such as the Glass Packaging Institute (GPI) and the National Glass Association (NGCA).
3. Japan: Japan has developed standards for pharmaceutical glass bottles, including JIS R3501 and JIS R3502. In addition, Japan has also established some standards and regulations for the packaging, labeling, storage, and transportation of glass bottles.
4. Australia: The Australian Standards Bureau has developed the AS/NZS 2233 series of standards, including AS/NZS 2233.1, AS/NZS 2233.2, etc., which specify the requirements for glass bottle dimensions, thickness, volume, physical performance, chemical performance, etc.

Among them, the Wine Bottle Standard (DIN 228) is one of the European standards for wine bottles, which is applicable to the production and use of various wine bottles. The standard specifies the specific details of the bottle shape, size, capacity, material, and quality requirements, including:

1. Shape: Wine bottles should be cylindrical, with a straight barrel-shaped mouth and a flat or hemispherical bottom.
2. Size: The size of wine bottles should comply with the standard, including the mouth diameter, height, bottom diameter, etc.
3. Capacity: The capacity of wine bottles should comply with the standard, usually 0.25 liters, 0.5 liters, 0.75 liters, 1 liter, 1.5 liters, 2 liters, etc.
4. Material: Wine bottles should be made of glass material, which can be transparent, amber, green, etc., but should comply with relevant national standards.
5. Quality requirements: Wine bottles should be free of significant defects, with a smooth and clean surface, and without defects such as bubbles, cracks, and scratches. In addition, the weight of wine bottles should comply with the standard, and the glass thickness should comply with relevant national standards to ensure the bottle’s strength.

The Wine Bottle Standard (DIN 228) also specifies the quality requirements for wine bottles, including the weight of the bottle. Specifically, for a 750 ml wine bottle, the minimum weight should be 300 grams, and the maximum weight should be 700 grams. For wine bottles of other capacities, the minimum and maximum weights should be appropriately adjusted according to the size of the capacity.

In addition, the Wine Bottle Standard (DIN 228) also specifies the glass thickness of wine bottles to ensure the strength of the bottle. Specifically, for wine bottles of different capacities, the minimum and maximum thicknesses are specified.

In summary, the Wine Bottle Standard (DIN 228) has specific provisions for the weight and glass thickness of wine bottles to ensure their quality and safety. The standard is a German standard and can be viewed and obtained on the official website of the German Institute for Standardization (DIN). The specific steps are as follows:

1. Open the official website of the German Institute for Standardization (DIN), the website address is https://www.din.de.
2. Enter “DIN 228” in the search box on the homepage and click the search button.
3. On the search results page, find “Flaschen für alkoholische Getränke; Flaschen für Wein und Schaumwein; Flaschenformen und -größen” (the German name of the wine bottle standard) and click on it.
4. After entering the detailed page of the standard, you can obtain the full content of the standard through paid download, online viewing, or subscription.

The official website of the German Institute for Standardization (DIN) is mainly in German, so a certain level of German reading ability is required. At the same time, the standard acquisition on the website generally requires payment, and the specific fees and methods can be inquired on the website.

Compared with the authoritative national standards, the German standard (DIN 228) is relatively comprehensive and authoritative. Therefore, some of our exported products have undergone LFGB testing, including glass bottles, bottle caps, bamboo caps, and rubber seals. Our factory has also passed the testing and certification of multiple third-party authoritative testing institutions such as SGS, TUV, and Intertek to ensure that our products meet the relevant quality and safety standards.
