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.

Applications

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.

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.

Test Procedures

Method A: Constant Internal Pressure Test

Method A tests the pressure resistance of a glass container by applying a constant internal pressure over a predetermined time. Its core requirements include:

Test Conditions: Tap water is used as the test medium. The sample must be filled with water at room temperature, within ±5°C of room temperature, to avoid additional pressure interference.

Equipment Requirements: The testing equipment must be capable of clamping the bottle mouth and suspending the sample, and equipped with an elastic sealing ring to ensure the sealing of the pressurized medium. The pressurization device must initially pressurize at a rate of 1.0 MPa/s ± 0.2 MPa/s and maintain a constant pressure.

Test Procedure:
Passability Test: Increase the internal pressure to the predetermined value, maintain it for 60 seconds ± 2 seconds, and observe whether the sample remains intact.

Incremental Pressure Test: Based on the passability test, gradually increase the pressure in increments of 0.1 MPa or 0.2 MPa until the sample breakage rate reaches 50% or 100%.

Method B: Incremental Internal Pressure Test

Method B determines the ultimate pressure resistance value by increasing the internal pressure at a constant rate until the sample ruptures. The standard specifies clear requirements for pressurization rate and test environment to ensure the accuracy and repeatability of test results.

Sampling and Precautions

The standard emphasizes that test samples must be glass containers that have not undergone other mechanical or thermal property tests to avoid affecting the internal pressure resistance test results. The sampling quantity should comply with regulations to ensure the representativeness and statistical significance of the test.

FAQ

1. What is this product?

Answer: It is a quantitative analysis system specifically designed to measure the total amount of static electricity generated by an object through simulated physical friction and charge capture.

2. What is the purpose of this product?

Answer: It helps determine how much static electricity accumulates on fabrics after friction, thereby assessing whether the fabric meets industry-mandated anti-static safety standards.

3. How does this product work?

A: A roller generates electricity by rubbing the sample. Faraday's law of induction then transfers all accumulated charge from the sample to the measuring instrument.

4. Why is this product important?

A: Electrostatic charge accumulation is a core evaluation metric for antistatic fabrics. Excessive charge levels can cause spark discharges, posing serious safety hazards in industries like petroleum and electronics.

5. Which industries is this product suitable for?

Answer: It is primarily applicable to textile quality inspection agencies, protective clothing manufacturers, petrochemical safety research institutes, and electronic product packaging R&D departments.
