ASTM D951 Test

ASTM D951 Standard Test Method with Spray Method for Water Resistance of Shipping Containers

The scope of the ASTM D951 shipping container test is to determine how well a container resists water. This standard can also be used to assess the ability of a container to withstand water deterioration.

This particular packaging test is just one of several shipping container tests. It is typically combined with other tests such as drop test, inclined impact test, vibration test and compression test. The overall aim is to ensure that the contents of the shipping container effectively protect its content during transportation difficulties.

The test requires at least three cups. Containers should be closed and sealed as usual. The containers should also be similar to the actual containers to be used. The standard does not allow the "gold unit" to be tested. Some tests will require emptying of shipping containers. Other tests will require the containers to have the content they prepared for dispatch.

ASTMD 951 package testTo complete the test laboratory must have the following equipment and features. These features are:

• Test Room - An experiment room or cabinet should be insulated and heated when necessary, in order to maintain proper temperature control. The floor must be covered with a false lath and have an outlet drain.
• sprays - The spray nozzles must be so large and spaced that the specified spray density is evenly distributed over the floor area. Spray nozzles should be placed so that the droplets fall off the force of gravity only when they hit the samples.
• Flow Control Valves - Flow control valves are required to control the density of the spray.
• Circulation System - A circulation system should consist of a fine flow strainer, pump, discharge bypass, pressure gauge and pressure regulating valve, required piping between the flow control valves, the spray nozzles and the water tank. .
• reservoir - When using a reservoir for storing and conditioning spray water, it will be equipped with a drain and a drain to facilitate water replacement at the start of each test. Compensated water regulated by float control should also be poured into this tank.
• Water Temperature Control - To keep the feed water at the desired temperature, a thermostatic controlled heating method is required.
• Conditioning Apparatus - Adequate facilities should be provided to condition the test specimens at appropriate humidity and temperature prior to testing.
