(Test Method)Standard Test Method for Drop Impact Resistance of Blow-Molded Thermoplastic Containers
Standard Test Method for Drop Impact Resistance of Blow-Molded Thermoplastic Containers
SIGNIFICANCE AND USE
These procedures provide measures of the drop impact resistance of the group or lot of blown containers from which the test specimens were selected.
It is acceptable to use these procedures for routine inspection purposes.
These procedures will evaluate the effect of construction, materials, and processing conditions on the impact resistance of the blown containers.
Before proceeding with this test method, reference the specification of the material being tested. Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in the materials specification shall take precedence over those mentioned in this test method. If there are no material specifications, then the default conditions apply.
SCOPE
1.1 This test method provides measures of the drop impact resistance of blow-molded thermoplastic containers as a summation of the effects of material, manufacturing conditions, container design, and perhaps other factors.
1.2 Three procedures are provided as follows:
1.2.1 Procedure A, Static Drop Height Method—This procedure is particularly useful for quality control since it is quick.
1.2.2 Procedure B, Bruceton Staircase Method—This procedure is used to determine the mean failure height and the standard deviation of the distribution.
1.3 The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are for information only.
Note 1—There is no known ISO equivalent to this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
