The Principles of

Standardization In May 1995 the IPC’s Technical Activities Executive Committee adopted Principles of

Standardization as a guiding principle of IPC’s standardization efforts.

Standards Should:

• Show relationship to DFM & 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

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 sell-

ing 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.

Why is there

a charge for

this standard?

Your purchase of this document contributes to the ongoing development of new and updated

industry standards. 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 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

participates 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 in order to allow as many companies as possible

to participate. Therefore, the standards revenue is necessary to complement dues revenue. The

price schedule offers a 50% discount to IPC members. If your company buys IPC standards, 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 847/790-5372.

Thank you for your continued support.
