451 Understanding MIL-STD-810G
Introduction The United States Department of Defense's MIL-STD-810G, Environmental Engineering Considerations and Laboratory Tests, released 31 October, 2008, is the most comprehensive collection of test methods and guidance for using them available today. It covers 29 basic tests with numerous procedures for most of them. Almost all the tests can be tailored to some degree, to ensure that the testing will meet its intended goal. While written with defense contractors in mind, 810G is just as valuable for commercial enterprises. Along with test methods, it includes guidance on what team members should be involved and their roles starting with the acquisition process and going through the final test report. It also contains world climatic information to help the test team to choose the proper environments for test. As a living document, MIL-STD-810G has continued to grow and evolve since its inception in 1962, and no test lab would be complete without both a copy of the document and at least one individual who understands how to apply it.
For Whom Intended This course is applicable to individuals from a wide range of commercial and government activities such as defense contractors, aerospace, aviation, shipbuilding, weapons systems, land vehicles and all branches of the Armed Forces. The course is intended for personnel involved with developing, applying, or reviewing environmental design and test specifications, standards and requirements. The target audience includes:
- Environmental engineering specialists
- Environmental test laboratory personnel
- Reliability and product assurance engineers
- Product designers
- Integrated Product Development Team leaders
- Contract writers and administrators
Brief Course Description This course provides understanding and guidance about the contents and proper application of MIL-STD-810G. The instructor follows the standard section by section, starting with the introduction and providing detailed information about each of the 29 methods, guiding the students not only in preparation of test methodologies but also in the type of equipment necessary to run each test.
For newcomers, this course will make MIL-STD-810G less mysterious and formidable. Those with some experience will gain a better understanding, to recognize mistakes and repeat successes.
Environmental design and test standards are a combination of valuable lessons learned and repetitive dogma. The ability to recognize the conflicting statements in referenced documents and obtain clarification as to which statement needs to be followed in a particular case will prove valuable to participants. This course will be presented in an interactive lecture-discussion format; lectures will be interspersed with class project work sessions to reinforce the students' understanding of the course material. Students are encouraged to introduce problems and questions from their own work for group discussions.
Diploma Programs This course is required for TTi's Environmental Engineering Specialist (EES) and Climatic Test Specialist (CTS) Diploma programs. It may be used as an optional course for any TTi Specialist Diploma Programs.
Related Courses An excellent follow-on course is course 405, Procedure Writing for MIL-STD-810G.
Prerequisites This course is intended for individuals with basic familiarity with environmental test procedures and facilities.
Text Each student will receive 180 days access to the on-line electronic course workbook. Renewals and printed textbooks are available for an additional fee.
Course Hours, Certificate and CEUs Class hours/days for on-site courses can vary from 14-35 hours over 2-5 days as requested by our clients. Upon successful course completion, each participant receives a certificate of completion and one Continuing Education Unit (CEU) for every ten class hours.
