ASTM B633, “Standard Specification for Electrodeposited Coatings of Zinc on Iron and Steel,” has just been updated.  The new 2015 Edition replaces the ASTM B633 2013 Edition which is now obsolete.  This is an technical revision to an essential plating spec, used throughout industry.  Here at Document Center we’ve sold hundreds of copies of the document over the years.  You’ll want a copy if you use this specification.

What exactly does ASTM B633 2015 address?  The specification covers the materials and processes to use for the electrodeposition of zinc coatings on iron or steel goods to protect them from corrosion.  It also includes information on the various tests you’ll use to confirm thickness, adhesion, corrosion resistance and so on.  This means the coating requirements and the sampling process (including specimen preparation) are part of the publication as well.

What’s new in the ASTM B633 2015 Edition?  An additional test has been added to give you another option when it comes to determining the thickness of the coating.  This means that there is one more ASTM standard included in the referenced document section as well.

ASTM B633, “Standard Specification for Electrodeposited Coatings of Zinc on Iron and Steel,” is a long time favorite for plating applications.  Now the new ASTM B633 2013 Edition is available in either paper format or pdf download.  The document covers material and process requirements for electrodeposited zinc coatings applied to iron or steel articles to protect them from corrosion.

You’ll find extensive changes in the ASTM B633-13 Edition from the previous 2011 Edition.  These updates center on the addition of RoHS requirements, added to limit the exposure of workers and others from exposure to toxic metals.  This means the addition of two additional types, V and VI, to permit non-chromate passivate treaments for the replacement of hexavalent chromium.

Most changes occur in the first 3 pages of the 6 page document.  For example, in the referenced documents section, there’s now the addition of the ASTM F1941 and ASTM F1941M, the inch and metric versions of “Specification for Electrodeposited Coatings on Threaded Fasteners.”

As you can see, RoHS – The Restriction of Hazardous Substances Directive – is having a profound impact on plating practices.  This new ASTM publication is another instance of industry working hard to promote safer processes as led by legislative direction.
