The TAEC recommends the use of the latest revision. 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. It is the position of IPCs Technical Activities Executive Committee that the use and implementation of IPC publications is voluntary and is part of a relationship entered into by customer and supplier. IPC Position Statement on Specification Revision Change Users are also wholly responsible for protecting themselves against all claims of liabilities for patent infringement. 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. Recommended Standards and Publications are adopted by IPC without regard to whether their adoption may involve patents on articles, materials, or processes. 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. 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. Standards Should: Show relationship to Design for Manufacturability (DFM) and Design for the Environment (DFE) Minimize time to market Contain simple (simplied) language Just include spec information Focus on end product performance Include a feedback system on use and problems for future improvement Standards Should Not: Inhibit innovation Increase time-to-market Keep people out Increase cycle time Tell you how to make something Contain anything that cannot be defended with data In May 1995 the IPCs Technical Activities Executive Committee (TAEC) adopted Principles of Standardization as a guiding principle of IPCs standardization efforts.
