Many defense departments all over the word manufacture their defense equipments taking into consideration the environment. If fact many standards have been set in order to emphasize on the making of these equipments. It is the department of defense test method standards which consider the environmental engineering and the laboratory tests.
Environmental engineering considerations and laboratory test have been a military standard followed in the United States of America.
It is a tri service partnership, which comprises of
a) the US army,
b) USFA and the
c) US navy.
d) Custodianship support is given by the army and the navy.
MIL-STD-810 does address a number of environmental conditions which may include exposure to high and low temperature, temperature shock, rain, salt fog rust testing, fungus, humidity, dust and sand exposure, low pressure for altitude testing, acceleration, leakage, explosive atmosphere, transport shock, gunfire vibration, etc.
This standard emphasizes on engineering processes and environmental management which can be of a lot of help to build confidence in the overall durability and environmental worthiness of a design. Moreover, this standard pays special attention to military acquisition programs and its planning on the environmental disturbances and stresses on the equipments.
The system has no say on the test specifications or design; it only pays attention on the tailoring of the equipments as per the environmental influences. The history of MIL-STD-810 goes back a very long way. In the year 1945 the Army Air Force provided with a formal methodology notifying the specifications which needed to be considered for testing equipments under assumed environmental conditions.
The USAF in 1965 introduced the technical report with informational data on the creation and development of environmental tests which may be natural or induced. These tests were meant for aerospace and ground equipments.
There have been various editions of MIL-STD-810
a) The first edition was released in 1962 and included only a single sentence
b) The subsequent editions were not very long as well, they did not elaborate the various specifications
c) MIL-STD-810D focused more on shock and vibration tests.
d) The latest edition is MIL-STD-810G this edition is also available on the web.
MIL-STD-810G has been divided into three parts. The first part deals with the general program guidelines. It focuses on the technical roles on the test tailoring and environmental design process. It gives details about how the environment may effect and equipment in its entire life-cycle.
The second part has carefully dealt with the laboratory test methods. It emphasizes laboratory methods that need to be focused while test tailoring the equipments. It contains environmental data and references which support the test engineer with considerable information on the methodology and laboratory test facilities.
The third part contains climatic data which has been gathered by several reliable sources across the globe. This part describes the climatic conditions and how it would effect the equipments; it also includes various ways to protect the equipments from change in climatic conditions in various parts of the world. This is of great help, since it enhances the durability of the equipment and helps the engineers.
