MIL-STD-810D Environmental Military Testing

Certification testing to MIL-STD-810D can be a daunting process. As one of the leading environmental test labs in the country, our team has developed a streamlined process. We guide customers from test program to the test report, expediting the compliance testing experience.

With dozens of test chambers, multiple shakers and unmatched custom engineering capabilities, we are able to offer short lead times on scheduling. Our pricing is affordable and with an ISO-17025 accredited quality program, our test reports are recognized and accepted throughout the world.

The remainder of this page provides an overview of the MIL-STD-810-C testing standard.

MIL-STD-810D was the first version of the standard to require more careful attention to environments throughout the development process. A course of action for determining and assessing the environments to which an item will be exposed during its service life was added.

With this revision, each individual method was revised to encourage more accurate determination of the environmental stresses that an equipment will encounter during its service life. Guidance for accelerated or aggravated testing during the design process is included in some cases.

Each test method was divided into two sections. The first section provides guidance for choosing and tailoring a particular test procedure. The second section of MIL-STD-810D includes step-by-step test procedures. In some methods, not only the test values, but also the sequence of steps is tailorable.

Despite the modifications, this standard still has limitations. MIL-810D does not address a number of tests. For instance, electromagnetic interference (EMI), lightning and magnetic effects., nuclear weapons and nuclear weapon’s effects are not considered.

In addition to those types of tests, there are also other limitations. For instance, piece parts, such as bolts, wires, transistors and integrated circuits are not included. Neither are tests of basic materials and certain aspects of the safety testing of munitions, such as rough handling tests.

The MIL-810 test standard includes a number of key definitions. Below is a brief summary of some of those descriptions.

An accelerated test is a test designed to shorten the test time by increasing the frequency or duration of environmental stresses that would be expected to occur during field use. An aggravated test is test in which one or more conditions are set at a more stressful level than the test item will encounter in the field in order to reduce test time, reduce sample sizes or assure a margin of safety.

A forcing function is a climatic or mechanical environmental input to an item of equipment that affects its design, service life or ability to function. This is also referred to as an environmental condition or an environmental stress. An induced environment is a local environmental condition that is predominantly man-made or equipment-generated. Also refers to any internal condition that results from the combination of natural forcing functions and the physical / chemical characteristics of the equipment.

Life Cycle History is the time history of events and conditions associated with an item of equipment from its release from manufacturing to its ultimate removal from service.

The life cycle should include the various phases that an item will encounter in its life, such as: handling, shipping and store prior to use; mission profiles while in use; phases between missions, such as stand-by or storage, transfer to and from repair sites and alternate locations; and geographical locations of expected deployment.

A platform is any vehicle, surface or medium that carries equipment. For example, an aircraft is the carrying platform for internally installed avionics equipment and externally mounted stores. The land is the platform for a ground radar set, and a man for a hand-carried radio.  Platform environment is the environmental conditions an equipment experiences as a result of being attached to or loaded onto a platform. The platform environment is a result of forcing functions induced or modified by the platform and any on-board environmental system.

As one of the leading MIL-STD-810 test labs in the country, Keystone Compliance has the expertise and capabilities to meet nearly every 810-testing requirement. In addition to environmental testing, we also have a full scope of EMC/EMI testing. Our capabilities include shielding effectivenessESDlightningHEMP and many other types of EMC testing. Our lab features seven EMC test chambers. We also have a reverberation chamber. We also provide expert EMC site surveys.

Lastly, we are also an ISTA-accredited package testing lab. We offer full package testing capabilities through our Keystone Package Testing subsidiary. In addition to ISTA and ASTM, we also are one of the few labs approved to complete Amazon package testing.
