Multifunctional leakage and sealing strength tester

.        The sealing integrity of packaging is crucial in many industries. For example, for medical industry, it can maintain the sterility of the product; for pharmaceutical industry, it can meet the standards and protect the effectiveness of the product; for food industry, it can ensure food safety and maintain freshness. Our Intelligent Leakage Tester GBM-D1 is an upgraded version of the existing sealing instrument products, which can support multiple test modes and meet the different test requirements of different products at one time

Standards

ASTM F1140 Blasting and creep of flexible barrier packaging (unconstrained)

ASTM F2054 Rupture testing (with limit plate)

ASTM F2095 Pressure decay leak testing (without restriction or with restriction plate)

ASTM F2096 Bubble leak testing (with water tank)

ISO 11607 Packaging of terminally sterilized medical devices

Testing Principle

Using destructive air pressurization methods (pressurization to burst or pressurization to specified pressure) to test the package tightness. The test methods can be implemented according to different standards including burst testing, leakage testing, creep testing, and air bubble testing. The test result can be expressed in a combination of testing pressure, holding time, testing package location, leakage location, etc.

Testing Method

Bursting testing: The instrument keeps increasing the pressure on the package until the package bursts. (Conform to ASTM F1140, ASTM F2054, YY/T 0681.3, YY/T 0681.9 standards).

Leakage testing: After inflating the package, it reaches a preset pressure and maintains the required test time under this pressure. Pressure management and leakage test are carried out according to the standard. Unconstrained or restricted plate test conditions can be selected. (Conform to ASTM F2095, ISO 11607-1 standards)

Creep testing: Under generate a constant pressure in the package, package closes to the burst limit, and keep it for a certain period of time, and evaluate the sealing performance when under pressure within the set time. Optional testing mode: creep and creep to failure (in accordance with ASTMF1140, YY/T 0681.3 standards).

Bubble testing: Put the package in water, then pressurize the package to a predetermined pressure, and maintain the predetermined pressure for a predetermined time (in accordance with ASTM F2096, YY/T 0681.5 standards).
