Test Item | Standard | Scope | Test Method |
Microbial Barrier Properties | DIN58953-6 | Porous materials. | Testing at moisture: Microorganisms are brought into drops on specimens. After drying the drops, it is investigated whether microorganisms have penetrated the underside of the specimens. |
Testing at dry: By cooling the air in the microbial barrier tester, which is sealed with the packaging material to be tested, an air flow (suction) enters a laboratory glass bottle. |
Package Integrity | Visual Inspection ASTM F1886/F1886M YY/T 0681.11 | This test method is applicable to packages with at least one transparent side so that the seal area may be clearly viewed. | Determinate channels in the package seal down to a width of 75μm [0.003 in.] with a (60-100) % probability. |
Vacuum Leak ASTM D(3078) | Determinate gross leaks in flexible packaging containing a headspace gas. | Test sensitivity is limited to 1×10−5 atm cm3/s (1×10−6 Pa m3/s) or even less sensitive. Small leaks may not be detected by this procedure. |
Dye Penetration ASTM F1929 YY/T 0681.4 | This test method is intended for use on packages with edge seals formed between a transparent material and a porous sheet material. The test method is limited to porous materials which can retain the dye penetrant solution and prevent it from discoloring the seal area for a minimum of 5 seconds. It’s require that the dye penetrant solution have good contrast to the opaque packaging material. | Detect and locate a leak equal to or greater than a channel formed by a 50 µm (0.002 in.) wire in package edge seals formed between a transparent material and a porous sheet material. A dye penetrant solution is applied locally to the seal edge to be tested for leaks. After contact with the dye penetrant for a specified time, the package is visually inspected for dye penetration. |
Package Strength | Seal Strength ASTM F88/88M YY/T 0681.2 | Measure the strength of seals in flflexible barrier materials. The test may be conducted on seals between a flexible material and a rigid material. | This test method measures the force required to separate a test strip of material containing the seal. It also identifies the mode of specimen failure. |
Withstand Internal Pressurization ASTM F1140/F1140M YY/T 0681.3 | Determine the ability of packages to withstand internal pressurization. Pressure differentials may occur during processes such as sterilization and transportation. | Brust Test: Packages are tested in apparatus that internally pressurizes the package until the package fails. The test measure is the maximum pressure detected before the package fails. |
Creep Test: Packages are tested in apparatus that internally pressurizes the package to a specified pressure and maintains that internal package pressure for a specific time. The test measure is pass/fail. |
Creep to Failure Test: Packages are creep tested and held until the package fails. The test measure is the time until failure. |
Simulated Transport ASTM D4169 YY/T 0681.15 | Test specimens consist of representative samples of complete shipping units, including actual contents. | Evaluate the ability of shipping units to withstand the distribution environment. |
