ASTM D1709 PDF

Method1. This standard is issued under the fixed designation D ; the number 1 These test methods are under the jurisdiction of ASTM Committee D20 on. Measure the impact resistance of plastic film, coated paper and other materials utilizing the free falling dart method ASTM D ASTM D test for plastic film impact resistance and free falling drop dart cover the determination of the energy that causes plastic film to fail under specified.

Atm dart is released to drop onto the center of the test specimen. The values obtained ast, these test variables are highly dependent on the method of film fabrication. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries.

Validating the specifications, value and safety of your raw materials, products and assets. By this ASTM D technique, a uniform missile weight increment is employed during the ASTM D test and the missile weight is decreased or increased by the uniform increment after the ASTM D test of each specimen, depending upon the result fail or not fail observed for the specimen.

Also, the ISO method wstm not allow the alternative testing technique described in Section 11 of this test method. A number of test samples are then impacted to determine an appropriate starting point for the weight of the dart. Hence, impact values cannot be normalized over a range of thickness without producing misleading data as to the actual d7109 resistance of the material.

Tests on materials that do not break, for any reason, are not considered to be valid. This test method is technically equivalent to ISO This statement and the test data also appear in the significance sections and appendixes of Test Methods D and D Also, the ISO method does not allow the alternative testing technique described in Section 11 of this test method.

If a test specimen passes, the drop weight is atm by one unit. Have a question about conducting the test for this standard?

By this technique, a uniform missile weight increment is employed during test and the missile weight is decreased or increased d709 the uniform increment after test of each specimen, depending upon the result fail or not fail observed for the specimen. This test method may be used for films whose impact resistances require masses of about 50 g or less to about axtm kg to fracture them. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Data obtained by one test method cannot be compared directly with the other test method nor with those obtained from tests employing different conditions of missile velocity, impinging d709 diameter, effective specimen diameter, material construction and finish of the dart head, and film thickness.

Film samples that can be cut to mm x mm 9″ x 9″ specimens A minimum of 30 specimens are required for the test Data: Standards can be obtained from appropriate standards authorities. Some films exhibit consistency when the initiation energy is the same as the total energy. Test method A specifies a dart with a 38 mm 1.

Assurance Testing Inspection Certification. It has been noted that certain materials may stretch so far as to bottom out at the base of certain test instruments without actually rupturing.

The confidence limits of data obtained by this procedure can, therefore, vary significantly, depending on the sample quality, uniformity of film gage, die marks, contaminants, etc. Test results can be used either as a quality control evaluation or for end use comparisons. By means of our testing expertise and modular product design, we will help find the solution that is right for you.

Send us a request Wilton UK: The method to analyze this test data is called the “Bruceton Staircase” method. Formally confirming that your products and services meet all trusted external and internal standards.

It is sometimes desirable to know the relationships among test results derived by different test methods. Auditing Consulting Sourcing Training.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This test method can be used for films whose impact resistances require masses of about 50 g or less to about 6 kg to fracture them. By this technique, the missile weight employed during the test is decreased or increased by uniform increments after the testing of each specimen, depending upon the result fail or not fail observed for the specimen.

The test results are shown in the Appendix. We are confident that we have what you are looking for.
