MIL-STD 202 Random Drop

This military drop test is used to determine the effects of random, repeated impact on component parts. These impacts are often due to handling, shipping, and other field service conditions. The dropping test is an accelerated test. It is a test designed to indicate structural and mechanical weaknesses of types not necessarily detected in random shock and random vibration tests.

During a life cycle materials are subjected to the stress that comes with transportation and use. This test is designed to determine the durability of these materials. This helps manufacturers identify potential warranty issues and performance issues so that they can produce the most durable product possible.

Keystone Compliance is a military drop lab with significant MIL-202 random drop lab testing experience. Our random drop testing lab is perfect for all your random drop compliance needs. We have a fully capable aerospace drop test lab. Our test engineers have an in-depth knowledge of drop test standards including  MIL-202G random drop and MIL-202H random drop testing.

The following information is extremely technical in nature. It provides a summary of Method 203, as derived from the MIL-STD-202 random drop section. Even though the language is from MIL-STD 202G random drop, it applies previous versions of the standard. This includes military random drop standards like MIL-STD 202H random drop.

What Apparatus Ought to be Created in the Best Random Drop Lab?

All drop testing ought to be performed in a random drop laboratory with a certified drop testing machine. This machine ought to consist of an assembly of either two or four steel cages. There should be provisions for rotation about a common axis. Steel sleeves are used to mount the specimen.

Keystone Compliance is a drop test lab capable of testing products to the drop testing requirements of various test standards including those specified in Method 203 of MIL-STD 202. Our drop test machine is capable of precise drops from different drop heights at different angles and onto different surfaces. Our trustworthy experts are experienced and knowledgeable about the various aspects of drop testing including testing for all your aerospace products.

What is the Proper Procedure for Method 203?

The specimen must be rigidly mounted by the normal mounting means in the steel sleeve so. It must be mounted so that no part of the specimen, including terminals or external hardware of the component, extend beyond the sleeve. When necessary, a suitable adapter may be used within the sleeve.

End caps shall not be used on the sleeves. Through bolts may be employed as needed to mount the specimens in the sleeve. Only one sleeve shall be placed in each cage during the test. The number of specimens mounted in each sleeve shall be limited only by the available space.

Specimens shall be subjected to the drop test for a period of 45 minutes. The test is performed at a speed of four to six (4 – 6) revolutions per minute.
