HEI is made up of manufacturers organized and based in North America (defined to be the United States of America, Canada, and Mexico) and actively engaged in North America. To be considered a manufacturer, the company must either own its own manufacturing facility or take responsibility for the manufacture of Institute scope products, including performing all required design and engineering of the product, being responsible to its customers for quality assurance, and fabricating the product or having it fabricated by subcontractors pursuant to a written agreement that reserves to the company the foregoing responsibilities.
There is an Association Section within HEI, which is currently made up of Tube Manufacturers. Associate members are companies that supply products to the HEI manufacturer members.
HEI holds two meetings each year, one in the spring and one in the fall. During the meeting, members of each Section gather to discuss industry and technical issues, as well as review the work of the Technical Committee. Each HEI section sponsors a technical committee which is charged with developing revising standards specific to its range of products.
Each technical committee meets at least twice a year, with each section member designating an engineer as its representative on the Technical Committee; ongoing communication among committee members assures that the standards are based on the latest available technology.
If you are interested in membership, please contact the HEI office.
