Detailed Overview/Outline

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.

The course also provides an introduction to the use of climatic testing procedures for Accelerated Life Testing (HALT), Reliability Testing, HASS and Environmental Stress Screening (ESS). A class project is included to provide 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.

Sponsor Background:
Tustin Technical Institute was founded in 1962 to provide training in engineering applications not found at conventional educational institutions. The training was aimed at individuals already working in industry and government to enhance their understanding of their everyday work.

We still continue this approach and specialize in presenting short courses from one day to eight weeks in duration, in various aspects of: engineering; design; computer software and hardware applications; non destructive testing; instrumentation; control; qualification testing procedures; quality assurance; reliability and various procedures associated with that area of activity called Environmental Engineering.

The thrust of our courses is to enable the course participants to understand the concepts involved in applying accepted engineering, testing and manufacturing procedures, so that products do not fail due to exposure to the environmental conditions which they may encounter in their everyday applications.

Our courses are offered to personnel actively involved in various aspects of engineering. They provide an opportunity to acquire specific application oriented education with particular emphasis on current technologies. TTI instructors are well qualified experienced individuals with "hands on" experience. They present the classes in a such a manner as to ensure that the participants understand the topics being covered to enable them to return to their jobs and apply techniques learned at TTI.

We offer a continuing education program leading towards a Specialist Certificate to enable individuals to have structured training program to follow over several years. The courses have been designed into modules to enable the participants to specialize in different areas. It enables them to improve their skills and prepare them for advancement in their chosen careers.

We offer a full range of our "open" courses at Santa Barbara at local conference facilities and additional courses are presented throughout the USA and many other countries: Australia; Canada; Denmark; Italy; Israel; Singapore; South Africa; South Korea; Sweden and the United Kingdom thus far.

Our courses are offered in three different ways:

• "Open" courses offered at various locations to individuals from many different organizations.
• "On-site" courses presented at client organizations facilities to clients employees only.
• "Distance learning" or correspondence courses for individuals to pursue on their own or in groups.

Why attend a TTI short course, now that you are qualified and have a good job?

·Remember....It's not enough to become qualified; you must remain qualified.

Many excellent technical courses are available at local colleges. However a TTI short course offers many advantages:

• The subject matter is covered in three to five days of intensive work/study.
• The classes are small so that attendees receive individual attention.
• There is good interaction between the attendees and instructor, providing interchange of ideas and solutions. Open discussions cover various topics that may need additional clarification.
• Attendees find that being immersed in the subject matter, away from the demands of job and family, provides an excellent opportunity to really absorb the concepts of the course material.
• TTI courses bridge the gap between academia and the working world. They update/supplement university education for people who must quickly grasp new concepts. They are aimed at "practical" solutions to everyday problems, and feedback from attendees is encouraged.
• TTI's instructors don't lecture, they teach. They have industry experience and understand what is needed in today's workplace.
• At the conclusion of a TTI short course, you will be able to return to your workplace and immediately apply the new ideas you acquired at TTI to your work assignments.
