Glass Bottle Internal Pressure Resistance Tester

The internal pressure resistance tester for glass bottles is a device specifically used to test the internal pressure - resistance performance of glass bottles. The following is a detailed description of its main uses, compliance standards, and technical parameters:

I. Main Uses

The internal pressure resistance tester for glass bottles is mainly used to evaluate the ability of glass bottles to withstand pressure under different pressure conditions. Through testing, we can determine whether glass bottles can withstand a certain internal pressure without breaking or deforming during the processes of filling, transportation, and use. This device is widely applied in industries such as beer brewing, pharmaceutical production, and food packaging, and is of great significance for ensuring product quality and consumer safety. In the beer - brewing field, the internal pressure resistance tester for glass bottles is used to inspect the internal pressure - resistance ability of beer bottles and other alcohol - beverage packaging bottles, ensuring that they will not break due to pressure changes during filling, transportation, and use. In the pharmaceutical production process, this device is used to test the internal pressure resistance of pharmaceutical packaging bottles such as antibiotic vials and infusion bottles, safeguarding the stability and safety of drugs during storage and transportation. In addition, in the food - packaging field, various beverage bottles such as carbonated beverage bottles and juice bottles also need to undergo internal pressure - resistance testing using this device.

II. Compliance Standards

The design and manufacture of the internal pressure resistance tester for glass bottles comply with a series of national and international standards to ensure the accuracy and reliability of test results. Among the more common standards are GB/T 4546 - 2008 *Test Method for Internal Pressure Resistance of Glass Containers* and ISO 7458:2004 *Test Method for Internal Pressure Resistance of Glass Containers*. These standards specify in detail the test methods for the internal pressure resistance of glass bottles, specimen preparation, test conditions, etc., providing a unified standard for the use of the tester.

III. Technical Parameters

- **Testing Pressure Range**: Usually it can reach 0 - 6Mpa or higher, and the specific range depends on the equipment model and testing requirements. This range can cover the internal pressure - resistance testing needs of most glass bottles. - **Display Accuracy**: Generally 0.001Mpa or higher, enabling precise display of pressure changes during the testing process. - **Pressurizing Medium**: Usually water is used as the pressurizing medium to ensure that no additional pressure impact is exerted on the glass bottles. Meanwhile, water as a medium is also convenient for controlling and monitoring pressure changes. - **Testing Speed**: The testing speed is usually relatively fast, and the time to test one bottle ranges from a few seconds to a dozen or so seconds, depending on factors such as the equipment model, testing pressure, and specimen specifications. The relatively fast testing speed helps improve testing efficiency and productivity. - **Overall Error**: Usually less than 0.5%FS (full - scale error), ensuring the accuracy and reliability of test results. - **Working Environment**: The equipment usually needs to be used in a certain working environment, such as a temperature range of 5 - 40°C (depending on the equipment model), and a relative humidity not exceeding a certain value. These working - environment requirements help maintain the stability of the equipment and extend its service life. - **Safety Performance**: The equipment is usually equipped with safety features such as leakage - protection control circuits to ensure the safety of operators. Meanwhile, the equipment also has the function of automatically detecting faults and prompting common faults, facilitating operators to promptly identify and resolve problems.
