YY/T 0681.13-2014: Test methods for sterile medical device package. Part 13: Slow rate penetration resistance of flexible barrier films and laminates

This part of YY/T 0681 is applicable to determine the penetration resistance of the anti-drive probe of flexible barrier film and laminates. In this test, biaxial stress is applied to the material at a constant test rate at room temperature, until penetration occurs; the force, energy and elongation before penetration are measured.

Part 13: Slow rate penetration resistance of flexible
barrier films and laminates
1 Scope
This part of YY/T 0681 is applicable to determine the penetration resistance of the anti-drive probe of flexible barrier film and laminates. In this test, biaxial stress is applied to the material at a constant test rate at room temperature, until penetration occurs; the force, energy and elongation before penetration are measured.
Note: Appendix A gives the precision and bias of the test methods as specified in this part.
2 Normative references
The following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) are applicable to this standard.
GB/T 2918 Plastics - Standard atmospheres for conditioning and testing
(GB/T 2918-1998, idt ISO 291:1997)
3 Terminology
The following terms and definitions apply to this document.
3.1
Elongation
The elastic / plastic deformation of the driving probe when it penetrates the flexible film.
3.2
Penetration resistance
6.2 The specimen size shall be 76 mm ?? 76 mm.
7 Instrument preparation
7.1 Set up and operate the instrument according to the instrument?€?s operation manual.
7.2 Install the probe.
7.3 Place the probe above the clamp and align it.
8 Number of specimens
Test at least 5 specimens for each sample.
9 State conditioning
9.1 According to the provisions of GB/T 2918 before the test, condition the state of the specimen under the conditions of temperature (23 ?? 2) ??C and relative humidity (50 ?? 5) % for at least 40 h.
9.2 Unless otherwise specified in this test method, the test is performed under standard laboratory conditions with a temperature of (23 ?? 2) ??C and a relative humidity of (50 ?? 5) %.
10 Procedure
10.1 Calibrate the test instrument according to the instrument manufacturer's instructions.
10.2 Select the force of the dynamometer in the range of 20% ~ 80% of the range when penetration occurs.
10.3 Use the sample cutter to cut at least five 76 mm ?? 76 mm specimens for each sample.
10.4 Measure the thickness in the center of the film sample (average of 3 readings).
Note 1: The thickness can be measured by ASTM D374 or GB/T 6672. It is
recommended to use Method C or Method D of ASTM D374 first.
Note 2: The accuracy of the thickness measurement methods in Table A.3 is based on ASTM D374.

Precision and bias
A.1 Precision
A.1.1 Precision data
Table A.1 and Table A.2 are the research results of laboratory collaborative tests conducted by ASTM on six materials in accordance with ASTM E691 in six
laboratories from 1988 to 1989. All samples of each material came from the same source, but the specimens were prepared in each participating laboratory. Each test result is an independently measured test value. Each laboratory obtained 5 test results for each material. Each laboratory conducted two parallel tests on each material; treated them as independent materials.
Tables A.3 and A.4 are based on the collaborative tests of the above
laboratories. But the data is from 3 laboratories and 4 laboratories, respectively. When using it, it should pay attention to the relatively small amount of data. Note: The following (A.1.2) explanation of r and R is only intended to give the concept of the approximate precision of this test method. Tables A.1 and A.3 should not be strictly used for the acceptance or rejection of materials, because these data are only for the materials involved in the verification, but do not represent other batches, conditions, materials or laboratories. Users of this test method should obtain data for specific laboratories and materials or between specific laboratories. An explanation of these data is given in A.1.2.
A.1.2 Concepts of r and R
A.1.2.1 If Sr is obtained from enough data, the difference between the two test results obtained by the same operator, using the same equipment, and on the same day exceeds the repeatability limit (r) of the material, it should be determined that the two test results are not equivalent.
A.1.2.2 If the SR is obtained from sufficient data, the two test results obtained by different operators, using different equipment, and in different laboratories for the same material exceed the material reproducibility limit (R ), it should be determined that the two test results are not equivalent.
A.1.2.3 For the judgement according to A.1.2.1 and A.1.2.2, the correct probability is about 95% (0.95).
