Need Chrysler Plating Specifications

Intro / synopsis: Move along if you're busy :-)
None of the sources/sites referenced on this page remain functional any more; the value of this page is only historical.

Q. Please I need help,

I need the following specification: Chrysler PS Plating code 30 and dichromate treated per Chrysler PS 1207 clear color. Thank you in advance.

? Hi. For me, this brings up the more general question of where does one go these days to obtain company-specific automotive specs? The AIAG site seems to be about selling QS-9000 caps, coffee mugs and cheerleading items rather than offering the specs that Mr. Wegner seeks :-)

How does one go about reaching (hopefully via the net) the buyers (or whoever) in order to get Ford, Daimler-Chrysler, or GM specs? Thanks!

A. Automotive specs availability depends on the maker, but they are not generally available to the public at large. Some companies (e.g.: VW, DaimlerChrysler) make them available over the net to registered suppliers.

There are some competitive reasons for this, but given that any supplier can gain access, it seems somewhat silly to most of us who supply the auto industry.

You can always try going to the auto makers site and requesting the spec, or you can try the Society of Automotive Engineers (SAE) site, but I can't promise you anything. If you are yourself a coater or parts manufacturer, you should be able to get the spec.

A. Whoever requires you to plate to this specification has a responsibility to get you a copy of that spec. Ask your customer for the spec. If you deal with a supplier, let them ask their customer and eventually someone should be able to get it to you. They cannot require you to adhere to a spec you have never seen before.

A. Actually, the burden of responsibility is with the supplier. One should not quote on business unless you understand what the requirements are. Also as an OEM supplier, who pays a subscription for various OEM specifications, we are prohibited from distributing these specifications due to copyright rules. They must be purchased individually, as needed.

thumbs up signThanks for the link, Dan! Unfortunately, that URL is limited to those who already have a password :-(

Marco wants to do what you suggest, i.e., "understand what the requirements are", and he does not seem to me to be asking anyone to violate copyright law nor supply for free something that others have to pay for.

Rather, his question of where or how he can register and obtain these necessary specs to try to break into this old boys' network and quote the potential customer the necessary finishing services remains open. While ISO, ASTM, SAE and similar specs are something a plating shop can buy and should be expected to have, all these years later we still haven't been able to tell Marco where he can go or what he can do to get in on the action and no longer be locked out and excluded from competing for business -- and it's embarrassing.

Thanks again,

Chrysler specification PS-79 code 30

Q. I need a copy of a plating specification sheet. The spec. is "PS 79 Code 30 + PS1207 Clear". It is a silver zinc plating with clear chromate.

A. Mollie,

Those are not internationally recognized numbers. They are specific to only one company, so you will need to get it from that company. PS means process solution as many times as it means process specification, so do not be shocked if there is more to the story.

RFQ: We are a ISO certified metal fabrication co. We are in need of a ISO certified plater. The parts we need plated will be of 12l14 steel. .750 of a in. long x .300 dia. we need zinc plate per Chrysler specification PS-79 code 30. with certification. We will make 1/2 million of them this run if your reasonable enough for price we will be sending more work your way. Are you interested?

P.S. My company has accepted a contract to manufacture a production part that calls for a zinc plate Chrysler specification PS-79 Code 30. For the life of me we cannot locate this spec. Not even from the industry that is requiring this spec. If anyone out there has it, it would be so much appreciated.

Ed. note: Sorry, this RFQ is old & outdated, so contact info is no longer available. However, if you feel that something technical should be said in reply, please post it; no public commercial suggestions please ( huh? why?)

A. PS-79 used to be a DaimlerChrysler standard for electroplated zinc. However, it is now just a designation within the broader standard PS-PLATING, which covers zinc, cadmium, and cadmium-tin (electroplated and mechanically plated). The designation PS-79 is specifying that the coating be electroplated zinc (for non-heat treated components), with a minimum thickness of 8 micrometers (Code 30).

This standard, like almost every standard developed, is copyright protected, and therefore cannot be freely distributed. You can obtain the latest revision of PS-PLATING from AutoWeb using the following link:

Ed. update Dec. 2013: That site no longer exists. now redirects to, which in turn redirects to, a software supplier -- but we don't see how that site can help anyone find specs anymore. Sorry.

Q. Can anyone advise where I can find a Chrysler standard (CS-9801) which is referenced in PS plating.

Ed. note June 2016: People looking to register for Chrysler specs can now start at
... which includes the instructions for Tier 1 suppliers, but advises Tier 2 & 3 users that they must get their Tier 1 to sponsor them.

Ed. update Nov. 23: That site no longer exists.
