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 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 (TAEC) 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

Why is there

a charge for

this document?

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

try standards and publications. Standards allow manufacturers, customers, and suppliers to under-

stand 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 847/790-5372.

Thank you for your continued support.
