Standard Test Method for Effect of Drycleaning on Buttons

Standard Test Method for Effect of Drycleaning on Buttons

SIGNIFICANCE AND USE
This test method is useful for determining the change to the listed properties (see 1.1.1 and 1.1.2) and if the changes are acceptable for the intended use. This test may be used for acceptance testing of commercial shipments of buttons.
If there are differences of practical significance between the reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them. As a minimum, test samples should be used that are as homogeneous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing. The test results for the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.
SCOPE
1.1 This test method is a means of determining the effect of drycleaning on certain physical attributes of buttons. The test method applies to buttons made from plastics, natural materials, cast metal, stamped metal and electroplated plastic.
1.1.1 The observed attributes of buttons made from plastic and natural materials include: color change, color transfer, solubility, swelling, and loss of finish.
1.1.2 The observed attributes of buttons made of metal and electroplated buttons include: color change, oxidation and color transfer.
This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

Standard Practice for Preparation of Low-Carbon Steel for Electroplating

ABSTRACT
This practice provides an aid for setting up a suitable cleaning cycle preparatory to electroplating of low-carbon steel and indicates some of the precautions that must be taken to maintain this cycle in good operating condition. The preparatory procedure involves three basic steps in the following order: (1) removal of oils, grease, and caked-on dirt; (2) removal of scale and oxide films by pickling; and (3) removal of any smut left on the surface and activation of the steel. The cleaning of racked parts, which shall subsequently be electroplated in still tanks, agitated tanks, and semi- and full-automatic equipment, should be performed following this cycle: (1) precleaning; (2) electrocleaning; (3) water rinse; (4) acid pickling; (5) alkaline descaling; and (6) water rinse. Parts in bulk, which shall subsequently be electroplated in hand-operated or automatic barrels, should follow this cleaning cycle: (1) alkaline cleaning; (2) water rinse; (3) acid pickling; and (4) water rinse.
SCOPE
1.1 This practice is intended as an aid to electroplaters in setting up a suitable cleaning cycle preparatory to electroplating of low-carbon steel (Note 1) containing less than 0.35 mass % of carbon and to indicate some of the precautions that must be taken to maintain this cycle in good operating condition.  
Note 1: The preparation of high-carbon steel for electroplating is covered in Guide B242.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Preparation of Magnesium and Magnesium Alloys for Electroplating

SIGNIFICANCE AND USE
3.1 Metals are electroplated on magnesium for various purposes: solderability, RF grounding, hermetic sealing, wear resistance, corrosion resistance, appearance, and electrical conductivity, for example. Because magnesium is covered with a naturally occurring oxide film, usual procedures for the preparation of metals for autocatalytic or electrolytic plating cannot be used.
SCOPE
1.1 This guide describes two processes used for plating on magnesium and magnesium alloys: direct electroless nickel plating and zinc immersion. Some users report that the direct electroless nickel procedure does not produce quite as high a level of adhesion as zinc immersion.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  For specific hazard statements, see 5.1.1 and 5.2.9.2.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Preparation of Aluminum Alloys for Electroplating

SIGNIFICANCE AND USE
3.1 Various metals are deposited on aluminum alloys to obtain a decorative or engineering finish. The electroplates applied are usually chromium, nickel, copper, brass, silver, tin, lead, cadmium, zinc, gold, and combinations of these. Silver, tin, or gold is applied to electrical equipment to decrease contact resistance or to improve surface conductivity; brass, copper, nickel, or tin for assembly by soft soldering; chromium to reduce friction and obtain increased resistance to wear; zinc for threaded parts where organic lubricants are not permissible; tin or lead is frequently employed to reduce friction on bearing surfaces. Nickel plus chromium or copper plus nickel plus chromium is used in decorative applications. Nickel plus brass plus lacquer or copper plus nickel plus brass plus lacquer is also used for decorative finishes, sometimes with the brass oxidized and relieved in various ways.  
3.1.1 Electroless nickel may be applied as a barrier layer prior to other deposits, or for engineering purposes.  
3.2 The preparation of aluminum and aluminum alloy mandrels for electroforming is described in Practice B432.
SCOPE
1.1 This guide covers cleaning and conditioning treatments used before metal deposition (Section 5), and immersion deposit/strike procedures (Section 6) that enhance the adhesion of metals that are subsequently applied to aluminum products by electrodeposition or by autocatalytic chemical reduction.  
1.2 The following immersion deposit/strike procedures are covered:  
1.2.1 Zinc immersion with optional copper strike (6.3).  
1.2.2 Zinc immersion with neutral nickel strike (6.4).  
1.2.3 Zinc immersion with acetate-buffered, nickel glycolate strike (6.5).  
1.2.4 Zinc immersion with acid or alkaline electroless nickel strike.  
1.2.5 Tin immersion with bronze strike (6.6).  
1.3 From the processing point of view, these procedures are expected to give deposits on aluminum alloys that are approximately equivalent with respect to adherence. Corrosion performance is affected by many factors, however, including the procedure used to prepare the aluminum alloy for electroplating.  
1.4 This guide is intended to aid electroplaters in preparing aluminum and its alloys for electroplating.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements see Section 7 and Appendix X1.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SIGNIFICANCE AND USE
5.1 This test method is useful for determining the change to the listed properties (see 1.1.1 and 1.1.2) and if the changes are acceptable for the intended use. This test may be used for acceptance testing of commercial shipments of buttons.  
5.2 If there are differences of practical significance between the reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them. As a minimum, test samples should be used that are as homogeneous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing. The test results for the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.
SCOPE
1.1 This test method is a means of determining the effect of drycleaning on certain physical attributes of buttons. The test method applies to buttons made from plastics, natural materials, cast metal, stamped metal, and electroplated plastic.  
1.1.1 The observed attributes of buttons made from plastic and natural materials include: color change, color transfer, solubility, swelling, and loss of finish.  
1.1.2 The observed attributes of buttons made of metal and electroplated buttons include: color change, oxidation, and color transfer.

ASTM B727-04(2020)(Practice)
Standard Practice for Preparation of Plastics Materials for Electroplating

SIGNIFICANCE AND USE
3.1 A variety of metals can be electrodeposited on plastics for decorative or engineering purposes. The most widely used coating consists of three layers—copper plus nickel plus chromium—for decorative applications. However, brass, silver, tin, lead, cadmium, zinc, gold, other metals, and combinations of these are used for special purposes. The key to producing electroplated plastics of high quality lies in the care taken in preparing plastics for electroplating. The information contained in this practice is useful in controlling processes for the preparation of plastics for electroplating.
SCOPE
1.1 This practice is a guide to the surface preparation of plastic materials for decorative and functional electroplating, where the sequence of chemical treatments may include: cleaning, conditioning, etching, neutralizing, catalyzing, accelerating, and autocatalytic metal deposition. Surface preparation also includes electrodeposition of metallic strike coatings immediately after autocatalytic metal deposition. These treatments result in the deposition of thin conductive metal films on the surface of molded-plastic materials, and are described in this practice.  
1.2 Once molded-plastics materials have been made conductive, they may be electroplated with a metal or combination of metals in conventional electroplating solutions. The electroplating solutions and their use are beyond the scope of this practice.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (See Section 4.)  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
