ASTM D951 Water Resistance of Shipping Containers

Testing Standard:

ASTM D951 Test Method for Water Resistance of Shipping Containers by Spray Method

Standard Number
ASTM D951

Standard Title
Test Method for Water Resistance of Shipping Containers by Spray Method

Overview for ASTM D951:

ASTM D951 is a test method used to evaluate the water resistance of shipping containers and their effectiveness to protect the inner contents. ASTM D951 is a testing standard that evaluates the water resistance of shipping containers. This test measures the ability of a container to protect its contents from water penetration under controlled conditions.

To conduct the test, a container is filled with a specific amount of water and placed in a specified position to simulate real-world conditions. The container is then examined for any signs of water penetration or damage to the contents. The test can be conducted on different types of containers, including corrugated boxes, crates, and drums.

The results of the test are reported based on the amount and location of water penetration into the container. If the container passes the test, it is considered to be water-resistant. This is an important factor for products that are shipped or stored in areas where they may be exposed to water or moisture.

ASTM D951 is commonly used by industries such as pharmaceuticals, electronics, and food packaging, where protection from moisture is critical to maintaining the integrity of the product. Purple Diamond Testing offers ASTM D951 as part of our packaging compliance and validation services.

Rationale for ASTM D951:

ASTM D951 – Test Method for Water Resistance of Shipping Containers by Spray Method. This test method helps decide the outer packaging’s ability to resist deterioration caused by water and is commonly performed in addition to other physical testing, including compression and drop testing. The ability to resist water during the distribution cycle ensures the containers’ continued protection of the inner contents.

Before going through with this test method, the samples must be conditioned sufficiently after closing and sealing the entire sampling. This process is done so that any adhesives, protective coatings, glued flaps, etc. will have reached the final normal conditioning. The sample will need to be at the same temperature as room temperature before the testing procedure begins. 

First though, the same must be weighed before and after conditioning. Pieces of the machinery are adjusted to the required intensity (both the nozzle and flow control must be adjusted). The sprays are then maneuvered throughout the entire operating system, including the inside the test room, until the whole space has reached a setting with an equal amount. Unless specified otherwise, the temperature must be 23 degrees Celsius, which is controlled by the thermostat.
