TIA Engineering Standards and Publications are designed to serve the public interest through eliminating
misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of
products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for
their particular need. The existence of such Publications shall not in any respect preclude any member or
non-member of TIA from manufacturing or selling products not conforming to such Publications. Neither
shall the existence of such Documents preclude their voluntary use by non-TIA members, either domestically
or internationally.
