Minimize time to market? Just include spec information?
Focus on end product performance? Include a feedback system on use and problems for future improvement Standards Should Not: Tell you how to make something?
Contain anything that cannot be defended with data Notice 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. Recommended Standards and Publications are adopted by IPC without regard to whether their adoption may involve patents on articles, materials, or processes.
By such action, IPC does not assume any liability to any patent owner, nor do they assume any obligation whatever to parties adopting the Recommended Standard or Publication. Users are also wholly responsible for protecting themselves against all claims of liabilities for patent infringement.
When an IPC publication is updated and a new revision is published, it is the opinion of the TAEC that the use of the new revision as part of an existing relationship is not automatic unless required by the contract. The TAEC recommends the use of the latest revision.
Adopted October 6, Your purchase of this document contributes to the ongoing development of new and updated industry standards and publications. Standards allow manufacturers, customers, and suppliers to understand one another better.
Standards allow manufacturers greater efficiencies when they can set up their processes to meet industry standards, allowing them to offer their customers lower costs. There are many rounds of drafts sent out for review and the committees spend hundreds of hours in review and development. Therefore, the standards and publications revenue is necessary to complement dues revenue.
If your company buys IPC standards and publications, why not take advantage of this and the many other bene? For more information on membership in IPC, please visit www.
