IPC 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 his
particular need. Existence of such Standards and Publications shall not in any
respect preclude any member or nonmember of IPC from manufacturing or
selling products not conforming to such Standards and Publication, nor shall
the existence of such Standards and Publications preclude their voluntary use
by those other than IPC members, whether the standard is to be used either
domestically or internationally.
