Drop Testing

Many products that are subject to handling during transport, installation, or repair are at risk of being dropped. Granted, handlers generally try to avoid these types of mishaps, but when equipment is out of your hands, it becomes out of your control. The best way to ensure that your product survives its journey from the factory to the point of installation is to drop test it and verify that it survives without damage. That way, your company isn’t answering warranty claims from customers who received damaged goods that left your warehouse in mint condition.

In addition to ensuring that products survive their journey from point A to point B, many products are at risk for being dropped or jarred throughout their lifetime. These products include handheld devices and tools, lab equipment, personal computers, field measuring equipment, construction tools, etc. In such cases, drop testing may be required to ensure that expensive tools or equipment are capable of surviving the perils of expected use and abuse.

Types of Drop Test Standards

Most drop test items must be able to withstand impact such as that which would be experienced when impact testing the item from the average height of a table (approx 30 inches) or more. However, drop test procedures vary by product type and industry. At NTS, our team is capable of performing drop and impact tests to whatever standards our customers specify. There are two different drop test procedures that NTS routinely performs:

· Telecommunications Equipment Telecommunications equipment covered under the GR-63-CORE standard must meet the drop methods and shock (height) criteria for containerized and unpackaged equipment. The drop testing methods include free fall, corner drops, and edge drops.

· Military Equipment — MIL-STD-810 is a United States Military standard specifying environmental test conditions to determine the durability of equipment. Procedure IV of that standard specifies criteria for examining material outside of or within the transit case as it is being loaded, unloaded, moved from a rack, placed within a transit case, or removed from a transit case. During the process, the test simulates an accidental drop or bump shock requiring a free fall from 18 to 48 inches depending on package weight and size. This testing methodology involves 5 to 26 drops and utilizes either a quick release tester or a fixture that elevates and drops one side of the package.

NTS is experienced in performing all types of drop testing, including commercial, telecommunication, military, or any other combination. Additional drop and impact test procedures include IEC 60068 and ASTM specifications for drop testing. We also perform drop and impact testing at high and low temperatures, high and low altitudes, or other extreme environments.
