(Test Method)Standard Test Method for Water Resistance of Shipping Containers by Spray Method
Standard Test Method for Water Resistance of Shipping Containers by Spray Method
SIGNIFICANCE AND USE
This test method is used to determine the water resistance of shipping containers. It can be used to determine the ability of the container to resist deterioration caused by water or the ability of the container to protect the contents from water. It is frequently used in conjunction with other tests made prior to or after the spray test, such as the drop test, inclined impact test, vibration test or compression test.
SCOPE
1.1 This test method covers the determination of the water resistance of shipping containers.
1.2 This test method is frequently used in conjunction with other tests made prior to or after the spray test, such as the drop test, vibration test, inclined impact test, or compression test.
1.3 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.
