**NPR 8715.3, Para. 1.13 requires HQ OSMA approval to vary from this at the Program level and Center Director approval to vary from this at the Project level. **
**Suppliers must show that all of their internal procedures include all of the requirements in the 8739 documents and that their operators and inspector training is traceable to the NASA Training Center Level A Instructors.**

## 
Use known GOOD materials, geometries and processes                            “how to”  or “lessons learned”

Disallow use of known BAD materials, geometries and processes            “how NOT to” or “lessons learned”

Inspection requirements and definition of defects at the Printed Wiring Assembly (PWA) level   “manufacturing quality defect reduction at low level of assembly”

Heighten role of customer in decision-making about risks associated with using new processes, rework and repair.   “customer participation in risk mitigation” 

Requirements for trained and certified operators, inspectors and local instructors.  “build in compliance to requirements”

## New Emphasis on Requirement Review

*From an October 29, 2007 joint message from Bryan O’Conner, Director OSMA HQ and Mike Ryschkewitsch, Director OCE HQ:*
- “...Some key points to be kept in mind:
- 1) NASA's primary purpose is to execute missions and deliver the products associated with them. Program or Project managers are charged with leading those implementations.  When they identify an institutional requirement, standard or other constraint which is impeding their efficient and effective progress they can and should challenge them.  This is not a unilateral decision process i.e. "the program cannot grade their own homework." But with that said, the clear intent of Mike's written remarks is that institutional requirements, standards, and constraints must provide value to the program and the agency.  If they do not, they will be challenged and removed.   2) The line organizations from HQ through the Center Directors and on down are the stewards of NASA’s capability to execute missions.  Their responsibility is to help the Programs and Projects be successful in both the short term and the long term.  This does not mean that they simply throw out the requirements, standards, lessons learned rules, etc of for the sake of expediency but neither should they try to enforce rules for rules sake.   3) What is required of all parties is a constructive dialogue among respectful partners to find a way forward....”** **

## Circular A-119				1995, 1998

**MEMORANDUM FOR HEADS OF EXECUTIVE DEPARTMENTS AND AGENCIES **
**SUBJECT:  Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities **
**Revised OMB CircularA-119 establishes policies on Federal use and development of voluntary consensus standards and on conformity assessment activities. Pub. L. 104-113, the "National Technology Transfer and Advancement Act of 1995," codified existing policies in A-119, established reporting requirements, and authorized the National Institute of Standards and Technology to coordinate conformity assessment activities of the agencies...**
**...****.Your agency must use voluntary consensus standards, both domestic and international, in its regulatory and procurement activities in lieu of government-unique standards, unless use of such standards would be inconsistent with applicable law or otherwise impractical****.**** In all cases, your agency has the discretion to decline to use existing voluntary consensus standards if your agency determines that such standards are inconsistent with applicable law or otherwise impractical. **** **
**(1) "Use" means***** *****incorporation of a standard in whole, in part, or by reference for procurement purposes, and***** *****the inclusion of a standard in whole, in part, or by reference in regulation(s). ****(2) "****Impractical" includes circumstances in which such use would fail to serve the agency's program needs; would be infeasible; would be inadequate, ineffectual, inefficient, or inconsistent with agency mission****; or would impose more burdens, or would be less useful, than the use of another standard.**

**“****Voluntary” = authors participate voluntarily.**
**“****Consensus” = all dissenting opinions of voting members must be resolved prior to publication.**

## IPC Workmanship Standards Most Closely Associated with NASA Workmanship Standards

**J-STD-001DS, Space Applications Electronic Hardware Addendum for J-STD-001D, RevDS dated Nov 2006     ****[includes base spec Class 3]**
**Training program for DS being administered through IPC, Beta class run at end of May, coming on line via independent suppliers.**
* **	**J-STD-001, Requirements for Soldered Electrical and Electronic Assemblies, RevE in Initial Draft, RevD dated 2005, (Base Rev dated 1992)*
**IPC/WHMA-A-620AS DRAFT, IPC/WHMA-A-620A Space Applications Electronic Hardware Addendum, First copy to be available for comment ~ Dec Sept 2007**
**Training program not yet developed. **
*	**IPC/WHMA-A-620A-CN, Requirements and Acceptance for Cable and Wire Harness Assemblies, RevC dated August 2007*

## Fast Track Directed for J-STD-001xS Adoption

-   Schedule is driven by CxP Program requirements effort.
-   Direction from NASA HQ OSMA was to pursue adoption as a priority over updating 8739 documents.

-   Requirement Gap Analysis performed (8739 minus J-STD-001DS)
-   Training program reviewed during IPC Beta run.
-   Low participation in process by Space industry.
-   90+ requirement gaps found
-   Risk rating of gaps results were bimodal
-   Training found to have significant drawbacks.
-   Workmanship’s and IPC’s industry distribution is <25% representative of NASA stakeholder community

**Fast Track Directed for J-STD-001xS Adoption**

##   NASA HQ requires notification and coordination with industry to be represented in final submission to IPC. Currently seeking industry reviewers and participants in J-STD-001DS activity.

-   Coordination meeting held in September at GSFC
-   All “hi” and “med” rated comments sorted and combined into 51.
-   J-STD-001xS paragraphs modified or added to address key concerns.  Some existing J-STD-001xS paragraphs go unchanged however interpretation will include NASA requirement.
-   J-STD-001xS _WILL NOT BE CONSIDERED A REPLACEMENT FOR 8739.1_ for Polymeric Applications.
-   30 comments prepared with reasons for submission to IPC Space Addendum Subcommittee.  NASA will request an interim change (implemented by coversheet).
-   NASA HQ requires notification and coordination with industry to be represented in final submission to IPC. Currently seeking industry reviewers and participants in J-STD-001DS activity.

## Overcoming Obstacles to J-STD-001xS Adoption

-   Training program is developed by J-STD-001 Training Subcommittee
-   IPC Training Materials:  2-5 “modules”, Classes 1-3 in book, hands-on can focus on a particular Class, 4-hour Space Addendum course (book only), training card “travels” with operator.  Training card notes modules taken but not Class trained to.
-   Local instructors must be traceable to Master Sites (IPC License holder).
-   NASA suppliers are creating their own versions of training programs outside of this process: Class 3 + Space Addendum + Local Requirements, not Master Site traceable.
-   Workmanship Project is negotiating a new one-week class “Class 3 + Space” which resembles NASA suppliers’ solution.  New subcommittee will be required.  Goal is to finish by Nov 08.

## Overcoming Obstacles to J-STD-001xS Adoption

-   Workmanship Project must build working relationship with supplier base.
-   Engineers working in the PWA and Cable Harnessing are encouraged to become a member of the NASA Workmanship Committee via the PBMA site(send an email to _[jeannette.f.plante@nasa.gov](mailto:jeannette.f.plante@nasa.gov)__  - or – __[rhumphre@pop300.gsfc.nasa.gov](mailto:rhumphre@pop300.gsfc.nasa.gov)__)_

## J-STD-001xS Adoption Timeline

## J-STD-001xS Transition Summary

-   Current NASA climate is encouraging critical technical review of all requirements.  OMB mandates serious look at using industry standards.
-   All effort being placed on making J-STD-001 Space Addendum a replacement for NASA-STD-8739.2 and NASA-STD-8739.3 as soon as possible.  (Space Addendum includes Class 3, Does not include 8739.1 Polymeric Apps).
-   NASA’s position on requirements is in industry coordination phase.  Goal is an Early 2008 document change (without revision change, will stay DS).  Request will be for addition or modification of 29 requirements.
-   Seeking a change from IPC on training offered.  Requesting a week-long class for Class 3 + Space Addendum with hands on at Space Addendum level.  Goals is mid-to-late 2008 for course offering.
-   NASA Workmanship Project will be required to provide high level of participation in IPC process to support the Space Addendum process.  Goal for adopting J-STD-001DS w/change is late 2008.
