Climatic Test Techniques

Course No. 230

(Course Outline shown below.)

For Whom Intended Environmental Engineering Specialists (as mandated by MIL-STD-810), environmental test laboratory engineers and technicians, specification writers, equipment designers, and quality and reliability specialists.

Brief Course Description An introduction to climatic testing with an overview of field test measurement and analysis. Test methods and conditions of commercial and military test specifications and standards are discussed.

Primary emphasis is on understanding the physics of each environment, and available measurement and control techniques. The course also covers selection and use of chambers for thermal, vacuum, corrosion and dust-particle testing. It provides an overview of compressors, pumps, blowers, and heating systems. There will be a discussion of liquid nitrogen (LN2) cooling systems and refrigeration equipment. All major MIL-STD-810 environments are covered, including humidity, solar radiation, fungus, salt fog, rain and ice, as well as syn-ergistic, combined environments testing. A class project provides supervised practice in using the course material.

The course is presented as a series of highly-interactive lecture/discussion sessions. Problems for individual and group solution are interspersed throughout the course to act as training aids and to evaluate class progress. Special-interest discussions are encouraged outside of the regular course sessions.

Certificate Programs This course is required for TTi’s Environmental Engineering Specialist (EES) and Climatic Test Specialist (CTS) Certificate programs. It is an elective for any other TTi specialist certificate program.

Prerequisites There are no definite prerequisites. However, this course is aimed toward individuals involved in related technical fields.

Text Each student will receive a course workbook, including most of the viewgraphs used in the course presentation.

Course Hours, Certificate and CEUs Open courses meet seven hours per day. Upcoming presentation dates can be found on our current open course schedule. 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.
