Standard Specification for Chromium Free Zinc-Flake Composite, with or without Integral Lubricant, Corrosion Protective Coatings for Fasteners

Standard Specification for Chromium Free Zinc-Flake Composite, with or without Integral Lubricant, Corrosion Protective Coatings for Fasteners

ABSTRACT
This specification establishes the basic requirements for non-electrolytically applied zinc-flake composite corrosion protective coating systems for fasteners. The requirements apply to appearance, adhesion, corrosion resistance, blisters, thread fit, hydrogen embrittlement, and total coefficient of friction. The coating systems covered by this specification do not contain hexavalent chromium, lead, cadmium, or mercury. This specification is intended for corrosion protection of inch and metric series threaded fasteners as well as for non-threaded fasteners such as washers and pins. This specification also covers test methods, application, inspection, and certification.
SCOPE
1.1 This specification covers the basic requirements for non-electrolytically applied zinc-flake composite corrosion protective coating systems for fasteners (See Note 1).
Note 1: The coating systems do not contain hexavalent chromium, lead, cadmium, or mercury.  
1.2 This specification is intended for corrosion protection of inch and metric series threaded fasteners with minimum nominal diameters of 0.250 in. for inch series and [6.00 mm] for metric as well as for non-threaded fasteners such as washers and pins.  
1.3 This coating system may be specified to consist of a zinc-flake basecoat, or a zinc-flake basecoat and topcoat (See Note 2).
Note 2: For threaded fasteners, the coating system will typically consist of a zinc-flake basecoat and topcoat.  
1.3.1 The basecoat is a zinc-rich material containing aluminum flakes dispersed in a compatible liquid medium. The zinc-flake basecoat may be specified to contain integral lubricant.  
1.3.2 Topcoats may be organic or inorganic in composition depending upon the specified requirements.
1.3.2.1 Organic topcoats consist of polymer resins, aluminum, dispersed pigments, and are colored in their applied state.
1.3.2.2 Inorganic topcoats consist of water-dispersed silicate compounds and are transparent in their applied state.
1.3.2.3 Topcoats contain integral lubricants and are applied in conjunction with zinc-flake basecoats to form a coating system with enhanced performance attributes such as increased corrosion resistance, total coefficient of friction properties, chemical resistance, and color.  
1.4 These zinc-flake basecoats and topcoats are applied by conventional dip-spin, dip-drain, or spray methods to fasteners which can be handled through a cleaning, coating, and curing operation. The maximum curing temperature is 482°F [250°C].  
1.5 The friction properties of the coating system may be determined by a standard test to verify process control or by a part specific test which requires the purchaser to establish and communicate technical criteria.  
1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.7 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 Specification for Aluminum Particle-Filled Basecoat/Organic or Inorganic Topcoat, Corrosion Protective Coatings for Fasteners

ABSTRACT
This specification covers corrosion-resistant coating consisting of an inorganic aluminum particle-filled basecoat and an organic or inorganic topcoat. The basecoat is a water-dilutable slurry containing aluminum particles dispersed in a liquid binder of chromate/phosphate compounds. The organic topcoats consist of polymer resins and dispersed pigments. The inorganic topcoats consist of ceramic oxide pigments dispersed in a liquid binder of chromate/phosphate compounds. These coatings are applied by conventional dip/spin, dip/drain, or spray methods. The coating systems defined by this specification can be applied to ferrous alloy steels, aluminum, and ferritic and austenitic stainless steels. The inorganic aluminum particle-filled basecoat and the subsequent topcoats are classified into three groups, with subsequent subgroups. Materials shall be tested and the individual grades shall conform to specified values of appearance, adhesion, corrosion, thread-fit, weathering, coating thickness, and humidity.
SCOPE
1.1 This specification covers the basic requirements for a corrosion-resistant coating consisting of an inorganic aluminum particle-filled basecoat and an organic or inorganic topcoat, depending on the specific requirements.  
1.2 The coating may be specified with basecoat only, or with the top coated with compatible organic polymer or inorganic topcoats, depending on the specific requirements.  
1.3 The basecoat is a water-dilutable slurry containing aluminum particles dispersed in a liquid binder of chromate/phosphate compounds.  
1.4 The organic topcoats consist of polymer resins and dispersed pigments and are for service where temperatures do not exceed 230 °C (450 °F).  
1.5 The inorganic topcoats consist of ceramic oxide pigments dispersed in a liquid binder of chromate/phosphate compounds and are for service where temperatures do not exceed 645 °C (1200 °F).  
1.6 These coatings are applied by conventional dip/spin, dip/drain, or spray methods.  
1.7 The coating process does not normally induce hydrogen embrittlement, provided that the parts to be coated have not been subjected to an acid cleaner or pretreatment (see Note 1).
Note 1: Although this coating material contains water, it has a relatively low susceptibility to inducing hydrogen embrittlement in steel parts of tensile strengths equal to or greater than 1000 MPa (approximately RC31). Normal precautions for preparing, descaling, and cleaning steels of these tensile strengths must be observed. An initial stress relief treatment should be considered prior to any chemical treatment or cleaning operation. Acids or other treatments that evolve hydrogen should be avoided. Mechanical cleaning methods may be considered. Some steels are more susceptible to hydrogen embrittlement than others and may also require hydrogen embrittlement relief baking after cleaning but before coating. Since no process can completely guarantee freedom from embrittlement, careful consideration must be given to the entire coating process and the specific steel alloy employed.  
1.8 The coating systems defined by this specification can be applied to ferrous alloy steels, aluminum, and ferritic and austenitic stainless steels.  
1.9 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.10 The following safety hazards caveat pertains only to the test methods portion, Section 6, of this specification: 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.

Standard Practice for Visual Evaluation of Metamerism

SIGNIFICANCE AND USE
4.1 Metameric color matches result from the use of different colorants (pigments, dyes, and the like) in achieving the same color match. Usually, the purchaser requires that the color match be nonmetameric; this practice permits this requirement to be quickly tested in both field and laboratory. Where nonmetameric matches are not possible or practicable, for cost or other reasons, some limitation of metamerism may be required. The procedures for estimating the magnitude of metamerism described in this practice provide methods for assessing the effectiveness of such limitation.
SCOPE
1.1 This practice describes visual methods for detecting metamerism and for estimating the magnitude of a metameric color difference.  
1.2 The practice is limited to the consideration of illuminant metamerism and observer metamerism. This practice does not cover gonioapparent samples.  
1.3 This practice does not provide for the computation of indices of metamerism based upon instrumental measurement of spectral characteristics.  
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.  
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.

Standard Practice to Evaluate Leaching of Water-Soluble Materials from Latex Paint Films

SIGNIFICANCE AND USE
4.1 Surfactant staining is a common problem with exterior house paints, particularly when subjected to humid environments (such as morning dew) shortly after application.  
4.2 Interior paints used in humid areas such as kitchens and bathrooms may also experience surfactant staining.  
4.3 Leaching of water-soluble materials may be dependent on colorant dispersions that are mixed into tint base paints. Other paint components may also affect the leaching of water-soluble materials.
SCOPE
1.1 This practice covers the ability of a latex paint film to resist staining caused by the leaching of water-soluble materials when contacted with water shortly after application.  
1.2 Water staining is attributed to the leaching of surfactants or other water-soluble materials from a paint film.  
1.3 The values stated in SI units are to be regarded as standard.  
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.

ASTM D4287-00(2023)(Test Method)
Standard Test Method for High-Shear Viscosity Using a Cone/Plate Viscometer

SIGNIFICANCE AND USE
4.1 The viscosity value obtained by this test method gives information about the flow properties of the material under high-shear conditions similar to those encountered during application: brushing (see Test Method D4958), spraying, electrostatic disk, or roll coating.  
4.2 This test method is suitable for all paints and varnishes whether they are Newtonian in behavior or not. However, due to the narrow gap between the stationary and rotary parts of high-shear viscometers, this test method is more reproducible for paints having finer pigment dispersions as determined by Test Method D1210.
SCOPE
1.1 This test method covers the determination of the viscosity of paints, varnishes, and related products at a rate of shear of 12 000 s−1.  
1.2 Paints and varnishes that dry very rapidly may not give reproducible results with this test method. Measurements made at elevated temperatures may also give poor precision due to loss of volatiles and to drying.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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.  
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.

ASTM F3078-15(2023)(Test Method)
Standard Test Method for Identification and Quantification of Lead in Paint and Similar Coating Materials using Energy Dispersive X-ray Fluorescence Spectrometry (EDXRF)

SIGNIFICANCE AND USE
5.1 This test method provides for analysis of Pb in applied paint using measurement times on the order of several minutes. It can be used to determine whether the sample of applied paint has an areal mass of Pb either substantially less than a specification limit, and therefore does not exceed it, or substantially above the specified limit, and therefore exceeds it.  
5.2 If the value obtained with this test method falls close to a specification limit, a more precise test method may be required to positively determine whether Pb content does or does not exceed the specified limit.
SCOPE
1.1 This test method describes an energy dispersive X-ray fluorescence (EDXRF) procedure for determining the areal mass of Pb in mass per unit area in paint and similar coatings on common substrates of toys and consumer products, such as plastic, wood, steel, aluminum, zinc alloys or fabric.  
1.2 This test method is applicable for homogeneous, single layer paint or similar coatings. The method does not apply to metallic coatings.  
1.3 This test method is applicable for a range of Pb mass per unit area from 0.36 μg/cm2 to approximately 10 μg/cm2 for Pb in paint and similar coatings applied on common substrates. The lower limit of this test method is between 0.36 and 0.75 μg/cm2 depending on the nature of the substrate. Based on the results obtained during the interlaboratory study (ASTM Report F40-1004), it is estimated that the applicable range of this method can be extended up to 50 μg/cm2.  
1.4 The values stated in SI units are to be regarded as standard. Values given in parentheses are for information only.  
1.5 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.

ASTM D16-23(Terminology)
Standard Terminology for Paint, Related Coatings, Materials, and Applications

SCOPE
1.1 This standard consists of technical terms used in standards under the jurisdiction of ASTM Committee D01 (on Paint and Related Coatings, Materials, and Applications), and of definitions suitable for use in these standards.
Note 1: When any definition in this standards is quoted or published out of the context of this standard, editorially insert the following delimiting statement “for paints and related coatings, materials, and applications” after the dash following the term (in the absence of an existing delimiting statement). This will limit the filed of application of the term and definition to that approved by this committee.  
1.2 In this terminology standard, definitions used in other ASTM standards are indicated by following the definition with the designation of that standard. In some cases, a relevant D01 subcommittee is also listed. Definitions influenced by those used by other organizations are indicated by the acronym of the organization. Primary terms are given in bold, while narrower and unapproved terms are given in italics.  
1.3 There are several specialized terminology standards under the jurisdiction of Committee D01, as follows: D804, D1695, D6440, D6488, and D7188. Few definitions from those standards are included in Terminology D16. Therefore, in searches for definitions of paints and coatings terms, these standards should be included where appropriate.  
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.
