Standard Practice for Determining the Effect of Overbaking on Organic Coatings

Standard Practice for Determining the Effect of Overbaking on Organic Coatings

SIGNIFICANCE AND USE
Most coatings are designed for a specific baking time and temperature. For a variety of reasons (line stoppages, rerouting back through ovens, oven overheating, etc.) the prescribed time or temperature, or both, of the bake is often exceeded. This practice has been found to be useful in evaluating the effects of overbakes on coatings.
SCOPE
1.1 This practice covers the determination of the time-temperature effect of overbaking on the physical and chemical properties of organic coatings.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7.

Standard Test Method for Determination of Strength of Colorants and Bases for Architectural, Marine, Maintenance, Commercial, and Industrial Coatings

SIGNIFICANCE AND USE
5.1 The test method results are suitable for use by manufacturers of colorants and bases for quality control purposes on manufactured product.  
5.2 The test method results are suitable for use by purchasers of colorants and bases for incoming quality control or the determination of money value of colorants and bases.
SCOPE
1.1 This test method covers the determination of strength of colorant dispersions, colored and white bases, for architectural, marine, maintenance, commercial, and industrial coatings.  
1.2 This test method applies to colorant dispersions and colored and white bases regardless of the methods used to disperse these materials.  
1.3 The resultant test value is in terms of percent strength in which a material stronger than standard is implied by values larger than 100 % and weaker than standard is implied by values less than 100 %. The value of 100 % implies exact strength conformance to the test method.  
1.4 This test method is suitable for the determination of strength when tolerances are set about standards that are prepared either by weight concentration or volume concentration.  
1.5 The test result is empirically determined. The user determines and supplies the standard for strength of the product under test and the test result is relative to that supplied standard.  
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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.8 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, Maintenance, and Distribution of Physical Product Standards for Color and Geometric Appearance of Coatings

ABSTRACT
This guide covers three levels of physical product standards (preparation, maintenance, and distribution) for color or geometric appearance, or both, of coatings commonly used in the coatings industry. Described here is terminology to describe each level, and techniques for generating and caring for standards. Product standards are the only standards by which products should be accepted or rejected for color or appearance. A master standard is generated from the concept color submitted by the customer. Duplicate master standards, when needed, are generated from the master standard. Working standards are generated from a duplicate master standard. They are used in the laboratory or on the production line to accept or reject the color or appearance of coatings. After initial generation, product standards must be maintained to ensure they remain valid. This guide considers the characteristics of product standards, factors to be considered in their creation, and factors to be considered in their replacement.
SIGNIFICANCE AND USE
5.1 High quality physical product standards for color or appearance are the keystone of a successful color control program. Standards are often grouped into three major categories: product standards, intermediate production control standards, and instrument standards. This guide deals only with physical product standards. Some instrument-based color control programs use “numerical standards,” derived from instrumental measurements of a physical product standard.
SCOPE
1.1 This guide covers three levels of physical product standards for color or appearance, or both, commonly used in the coatings industry, provides terminology to describe each level, and describes techniques for generating and caring for standards.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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 Practice for Evaluation of Aging Resistance of Prestressed Prepainted Metal In a Dry Heat Test

ABSTRACT
This practice details the standard procedure for evaluating the resistance of prestressed prepainted metal panels to cracking, or loss of adhesion, or both, after accelerated heat aging by dry heat test. This test method requires the use of gravity or forced air laboratory oven, bench vise, bending dies or test shims, 10x magnifier, and adhesive tape.
SCOPE
1.1 This practice can be used to evaluate the resistance of a prestressed prepainted metal panel to cracking, or loss of adhesion, or both, after accelerated heat aging. Most coil coated products are formed and bent into specific shapes to produce a final product. These operations introduce stresses, which may be relieved by cracking of the coating after aging.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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 Testing Water-Borne Architectural Coatings

ABSTRACT
This guide covers the selection and use of procedures for testing water-borne architectural coatings to be used on exterior, interior, or both types of surfaces. The properties that can be examined by the test methods listed herein are as follows: liquid paint properties (skinning, condition in container, coarse particles and foreign matter, density or weight per gallon, fineness of dispersion, flash point, odor, absorption, colorant acceptance, dilution stability, package stability, heat stability, and settling); coating application and film formation characteristics (brush application properties, brush drag, roller application properties, roller spatter, spray application properties, touch-up uniformity, consistency (low-shear viscosity), rheological properties of non-Newtonian liquids, sag resistance, levelling properties, and drying properties); appearance of dry film (color appearance, color differences by visual comparison, color differences using instrumental measurements, directional reflectance, gloss, sheen, hiding power, and yellowness index); properties of dry film (abrasion resistance, adhesion, flexibility, resistance to household chemicals, color change of white enamels, washability and cleansability, blister resistance, exposure resistance, chalking, checking, cracking, erosion, flaking, mildew resistance, and fume resistance); and Coating Analysis (chemical analysis, volatile content, nonvolatile volume content, water content, pigment content, pigment analysis, nonvolatile vehicle content, vehicle separation, and nonvolatile vehicle identification).
SCOPE
1.1 This guide covers the selection and use of procedures for testing water-borne coatings to be used on exterior, interior or both types of surfaces (Note 1). The properties that can be examined or, in some cases, the relevant test procedures are listed in Table 1 and Table 2.
Note 1: The term “architectural coating” as used here combines the definition in Terminology D16 with that in the FSCT Paint/Coatings Dictionary, 2 as follows: “Organic coatings intended for on-site application to interior or exterior surfaces of residential, commercial, institutional, or industrial buildings, in contrast to industrial coatings. They are protective and decorative finishes applied at ambient temperatures. Often called Trade Sales Coatings.”
Note 2: Architectural coatings that are designed to give better performance than most conventional coatings because they are tougher and more stain and abrasion resistant are covered by Guide D3730.  
1.2 The types of organic coatings covered by this guide are as follows:
(1) Type 1 Interior Latex Flat Wall Paints,
(2) Type 2 Exterior Latex House Paints,
(3) Type 3 Water-Borne Floor Paints, and
(4) Type 4 Interior Latex Semigloss and Gloss Paints.

Standard Practice for Use of Pictorial Surface Preparation Standards and Guides for Painting Steel Surfaces

SIGNIFICANCE AND USE
4.1 The appearance of the various degrees of dry and wet abrasive blast cleaning, hand and power tool cleaning, and water jetting are influenced by the initial rust grades of the steel being cleaned and/or the type and condition of the coating on the existing steel. The standards and guides aid visually in judging and evaluating the degree of rusting and/or paint deterioration before cleaning and the degree of cleaning of steel surfaces prior to painting.  
4.2 Five methods have evolved because of differences in the practice of using visual standards and guides throughout the world, and the method of surface preparation employed. In Europe, the visual standards (Method A) are used as the primary means of assessing the degree of cleaning. In the U.S., the SSPC written definitions take precedence with the visual guides and reference photographs used as a supplement. The visual guides and reference photographs of Methods B, C, and D conform to the SSPC written definitions. There are written definitions for Method E, however, the visual guide for Method E does not contain a complete set of pictorials corresponding to each surface cleanliness definition.
SCOPE
1.1 The visual surface preparation guides and standards consist of a series of color prints available as separate publications. Five different sets of photographs are described in this standard, designated as Method A (ISO/Swedish Standard2) and Methods B through E (SSPC Guides and Reference Photographs3). The methods differ in the depiction of the initial surface, in the definition and depiction of the cleaning conditions, and in the number of cleaning methods included. Because of these differences, the specifier should state which guide to use.  
1.2 The colored visual surface preparation guides represent different conditions of hot-rolled carbon steel before and after surface preparation. Prior to cleaning, there are four rust grades, A to D, that cover the range from intact mill scale to 100 % rusted and pitted steel. The standards then depict the appearance of the initial conditions after cleaning by one or more methods (for example, dry abrasive blast cleaning) to various degrees of thoroughness. In addition, Method B includes three painted conditions that contain various degrees of deterioration. The Guide3 depicts these conditions after various degrees of dry abrasive blast cleaning. Method C includes four rust grades and three painted conditions that contain various degrees of deterioration. The Guide4 depicts these conditions after various degrees of hand and power tool cleaning. Method D includes two rust grades and four painted conditions that contain various degrees of deterioration. The Guide5 depicts these conditions after various degrees of water jetting, with three levels of flash rusting. Method E includes two rust grades. The Guide6 depicts these conditions after various degrees of wet abrasive blast cleaning, with three levels of flash rusting.  
1.3 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 Application and Evaluation of Brush and Roller Applied Paint Films

SIGNIFICANCE AND USE
4.1 Laboratory measurement of application properties of architectural coatings generally employ a blade-type applicators that lay down films of highly uniform thickness. Applicators, such as brushes and rollers, typically apply films that lack uniformity due to variations in rheology, film build, flow and leveling properties resulting in the practical hiding of most paints being less than that measured on films applied with a blade-type applicator. This guide provides an indication of the actual application properties of the paint, as applied by a contractor or consumer.
SCOPE
1.1 This guide describes procedures for the application of brush or roller, or both, applied paint films to sealed wallboard for evaluating application properties.  
1.2 Because both the application and panel evaluation are subjective, this guide should be used only for comparative testing within one laboratory using one operator for each set of applications, as the ratings assigned by different laboratories may not agree.  
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.  
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.
