The Principles of
Standardization
In May 1995 the IPC’s Technical Activities Executive Committee (TAEC) adopted Principles of
Standardization as a guiding principle of IPC’s standardization efforts.
Standards Should:
• Show relationship to Design for Manufacturability
(DFM) and Design for the Environment (DFE)
• Minimize time to market
• Contain simple (simplified) 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
Notice
IPC Standards and Publications are designed to serve the public interest through eliminating mis-
understandings between manufacturers and purchasers, facilitating interchangeability and improve-
ment 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 adop-
tion 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 them-
selves against all claims of liabilities for patent infringement.
IPC Position
Statement on
Specification
Revision Change
It is the position of IPC’s 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.
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, 1998
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.
IPC spends hundreds of thousands of dollars annually to support IPC’s volunteers in the standards
and publications development process. There are many rounds of drafts sent out for review and
the committees spend hundreds of hours in review and development. IPC’s staff attends and par-
ticipates in committee activities, typesets and circulates document drafts, and follows all necessary
procedures to qualify for ANSI approval.
IPC’s membership dues have been kept low to allow as many companies as possible to participate.
Therefore, the standards and publications revenue is necessary to complement dues revenue. The
price schedule offers a 50% discount to IPC members. If your company buys IPC standards and
publications, why not take advantage of this and the many other benefits of IPC membership as
well? For more information on membership in IPC, please visit www.ipc.org or call 847/597-2872.
Thank you for your continued support.
