IPC PROCEDURE FOR APPROVING

TEST METHODS FOR IPC-TM-650

Development and/or revision of test methods is encouraged. This procedure has been developed to simplify the pro-

cess, and to assure timely and efficient processing.

Every newly proposed or revised proposal to an existing test method must have a cover sheet. The cover sheet can be

found in the front of the IPC Test Methods Manual, IPC-TM-650, or can be obtained from the IPC.

1. Complete the heading with the appropriate information. If the method is new, a number will be assigned by the

IPC.

2. Section 1 needs to be ﬁlled out and returned to the IPC. You need the following information for this section.

• Reason for initiating or revising the test method(s). Include whether the test method(s) was the result of a round

robin program.

• All standards/speciﬁcations that the originating task group is aware of that will be affected by the method(s).

3. The cover sheet will be returned to the originating committee with a number assigned to the new method(s)s and

a disk containing the template and test method outline that needs to be followed. The IPC will verify that all

affected groups have been identiﬁed and notify the chairman of all affected groups.

The originating task group can now set up as many meetings as they feel necessary to work on the test method(s).

The test method(s) will be circulated among the task group as many times as needed until the task group is satis-

ﬁed.

4. Section 3 of the cover sheet is then ﬁlled out and returned to the IPC along with the test method(s). The follow-

ing will then occur:

• The test method(s) are sent to the Test Methods Subcommittee and all subcommittees and task groups affected by

the test method(s) for comment. Any test method(s) revising any current method(s) will be circulated with the

current method for comparison purposes.

• The comments are then compiled and returned to the originating task group for disposition. All of those who

comment will be informed of the schedule for this meeting so that they may attend.

• Depending upon the level of comments or if the originating task group makes signiﬁcant technical changes to the

method(s) as a result of these comments, a second circulation may be necessary. The IPC staff and the Test Meth-

ods Subcommittee Chairman will make this determination.

• Test method(s) accepted by one committee and rejected by another will be returned to the Test Methods Subcom-

mittee. The subcommittee will then schedule a meeting to resolve the conﬂicts and disposition of the method(s).

• If approved or if no comments are received, then the test method(s) will be submitted for typesetting.

5. The ﬁnal typeset version of the test method(s) must be reviewed and released by the originating task group chair-

man and the chairman of the Test Methods Subcommittee prior to its printing in the IPC-TM-650.

Test Method Circulated (2)

Committee working on test method

contacts IPC staff liaison to have the

method circulated to Test Methods

Subcommittee (7-11) and affected

committees for 60 day review period.

(Affected committees include

committees that reference the method

in one of their documents, or the

originating committee of the method.)

B) Revision to test method

proposed.

Test Method Proposed (1)

A) New test method proposed

for IPC-TM-650 or

committee document.

Comments Compiled (3)

All comments received are

compiled and forwarded on to

the committee working on the

method.

Comments Reviewed (3)

All comments are resolved by

the committee working on the

method. The final draft of the

method is then either re-circulated

to all affected committees or

circulated to committee working

on method and Test Methods

Subcommittee (7-11).

Test Method Re-circulated (2)

The committee working on

the test method reviews the

comments and chooses to

re-circulate the method to 7-11

and all affected committees.

Interim Final Circulated (4)

The interim final version of

the test method is circulated to

the committee working on the

method and the Test Methods

Subcommittee (7-11) for a 30

day review period.

Comments Compiled (4)

Test method comments or votes

of approval are compiled and

forwarded on to the committee

working on the test method.

Method Re-Circulated/Typeset (4)

After reviewing the comments,

the committee working on the

test method chooses whether to

re-circulate the test method or

submit it to IPC liaison for typeset.

Test Method Submitted for Final Sign-Off (4)

The IPC liaison submits the typeset version

of the test method to the chair of the

committee working on the method, as

well as the chair of the Test Methods

Subcommittee (7-11).

Test Method Approved (5)

The committee chairs sign-off on

the test method, approving it for

inclusion in the next IPC-TM-650

update.

IPC TEST METHODS MANUAL

FOREWORD

The purpose of this test methods manual is to contain, in one document, pertinent information on test methods that

will be useful to manufacturers and users of printed boards, electronic assemblies, hybrid circuits, discrete wiring, and

ﬂat cable. It provides an organized reference source for test methods, which can be utilized by the testing laboratories

of manufacturers and users of products of the electronic interconnection industry. In addition, this document provides

an organized reference source of test methods that can be utilized by the technical committees of the IPC, in their work

to develop new standards and speciﬁcations.

TELLS HOW TO TEST — NOT REQUIREMENTS FOR ACCEPTANCE

This test methods manual is designed to provide speciﬁc information on test methods. It does not attempt to establish

acceptability levels for performance. Details of performance requirements can be found in appropriate IPC speciﬁca-

tions, which are referenced in the manual.

ABOUT THE TEST METHODS IN THIS MANUAL

Each test method includes a brief description of its purpose and provides a listing of all equipment, apparatus, and

other required materials necessary to perform the speciﬁed procedures. The test method may also include brief men-

tion of limitations and/or speciﬁc areas of non-applicability.

Procedures for performing each test method are detailed in this publication. They include information on speciﬁc con-

ditioning, curing, or other specimen preparation, as well as the speciﬁc procedure for conducting the test. Each pro-

cedure is sufficiently detailed so that the test can be accomplished by a technician familiar with standard laboratory

practices and procedures.

SOURCE OF TEST METHODS IN THIS MANUAL

Most of the test methods published in this manual have been taken from previously approved standards and speciﬁ-

cations of the IPC. Therefore, these test methods have been reviewed and approved by the entire membership of the

IPC. Since the IPC membership represents both manufacturers and users, and since they represent technical represen-

tatives from supplier member companies and technical experts from many government agencies, the standards and

speciﬁcations approved by the IPC have a broad base of acceptance.

In the event of a dispute over details of an IPC test method, the details of the test method published in the individual

IPC standards and speciﬁcations should be considered the governing document.

Other test methods included in this manual have been taken from government standards or other standards that have

extensive use in the electronic interconnection industry.

FUTURE TEST METHODS

The IPC will continue its efforts to maintain an awareness of all new developments in test methods. As new require-

ments for testing are developed, they will be studied by the IPC Test Methods Subcommittee and by other appropri-

ate technical committees of the IPC. Where appropriate, such test methods will be approved and formatted for inclu-

sion in the IPC-TM-650.

With regard to new test methods, the IPC seeks ideas and recommendations from all who are concerned with printed

board and related interconnection products. If you have ideas for new tests that are needed, or information on new

tests that are available for use in our industry, contact the IPC at 3000 Lakeside Drive, Suite 309 S, Bannockburn, IL

60015, Tel 847/615/7100, Fax 847/615/7105.
