450 Environmental Test Specifications

For Whom Intended  This course is intended for commercial and government personnel involved with developing, applying, or reviewing environmental design and test specifications, standards and requirements. The target audience for this course 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 environmental design and test specifications, standards and requirements documents. For newcomers, this course will make environmental design and test less mysterious and formidable. Those with some experience will gain a better understanding, to recognize mistakes and repeat successes.

Harsh EnvironmentsProduct test and evaluation have undergone major changes in recent years. This course will show how these changes impact the function and responsibilities of the environmental engineering specialist. In addition, it will help the student successfully adapt to change by providing a perspective for using future environmental specifications and standards.

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.

Prerequisites  This course is intended for individuals who have completed all other formal training requirements for TTi’s Diploma Programs and have some familiarity with environmental test specifications and standards. Others who are not participating in the TTi EES program should have at least a basic understanding of environmental test procedures and facilities.

Diploma Programs  This course is required for TTi’s Environmental Engineering Specialist (EES), Dynamic Test Specialist (DTS) and Climatic Test Specialist (CTS) Diploma Programs and is recommended as the final course in the series. It may be used as an elective for any other Specialist Diploma Program.
