Colorful RoHS compliance passivation gives corrosion resistance ability of hours according to ASTM B until white spots-also intended to parts used in a high corrosive environment —outdoor.
Current edition approved Jan. It is recommended that the following appropriate recommended practices and guides be used: If the purchaser does not specify an exception to heat treatment, then the plater shall use Table 1 in B to determine the appropriate heat treatment for the steel based on its tensile strength.
The type of passivation is determined according to the required characteristics, and is divided into groups: Zinc and Zinc alloys, such as zinc-nickel will surely play a more significant role as metals such as Cadmium are destined for the elements’ Valhalla. This standard does not purport to address all of the safety concerns, if any, associated with its use.
NOTE 5—Thickness methods that rely on the purity of the zinc deposit may not be sufficiently accurate when evaluating coatings produced from non-cyanide zinc solutions.

Zinc coating with colorful RoHS compliance passivation. SC 4 very severe. Already Subscribed to this document.
It does not cover zinc-coated wire or sheets. The designer and engineer must take into account several considerations to stay at the forefront of the finish potential. The coating is made according to demand, where the distribution is as follows: The size of the sample and the criteria for compliance are determined by the application of statistics.
As much as the last layer of the passivation is thin the electrical resistivity is low. For example, a cold-rolled steel surface shall not be used to represent a hot-rolled steel surface. The values are only relative, since individual studies in various parts of the world have resulted in? Yellow-iridescent Black Olive Green. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
B Where satm conditions are valid only for coatings with chromate conversion coating. Available colors are iridescent and black Colorless chromate passivation gives corrosion resistance ability of 12 hours according to ASTM B until white spots-intended to parts used in a light corrosive environment —indoor.
The Zinc coating provides a smooth look as well as good anti-corrosive protection. Iridescent and Colorless passivation is thin and has low electrical resistance.
Electrical charasteristics As much as the last layer of the passivation is thin the electrical resistivity is low. The electroplated article shall be clean and free of damage.
Last previous edition approved in as B — 98e1. To minimize problems of this sort, the speci? Zinc plated components vary from one industry to another. To determine the nature of accuracy or revision level please verify above data with current releases: The purchaser retains the right to perform any of the inspections and tests set forth in this speci? The separate specimens may also be cut from scrap castings when ferrous alloy castings are being electroplated.
ASTM B – 07 Standard Specification for Electrodeposited Coatings of Zinc on Iron and Steel
There are different passivation colors: NOTE 1—Surfaces should be activated as soon as possible following baking and handled carefully to avoid contamination and maintain an active surface for post processing.
B — 07 Standard Speci? Responsibility for Inspection S1. Baked parts shall not crack or fail by fracture when tested in accordance with The chromate, passivate, or supplemental? Need more than one copy? Our Zinc coating is carried out according to: Your Alert Profile lists the documents that will be monitored. We have no amendments or corrections for this standard. The rust not only harms the aesthetically smooth look, but also its mechanic needs.
The sampling plan used for the inspection of the quality coated article shall be agreed upon between the purchaser and producer. The procedure is known as sampling inspection.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Subscription pricing is determined by: In this event, the basis metal shall be subjected to such polishing or buffing operations as are necessary to yield deposits with the desired? High strength steels tensile strength greater than MPa shall not be electroplated.
The type of passivation is determined according to the required characteristics, and is divided asrm groups:. A number in parentheses indicates the year of last reapproval. Therefore, it is recommended that supplementary treatments not be applied to zinc coatings having a nominal thickness less than 5?
