2、ion. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide covers the selection and use of test methodsfor high-performance interior architectural wall coatings(HIPAC) that di
3、ffer from more conventional coatings by beingtougher, more stain-resistant, more abrasion-resistant and,ordinarily, designed to be applied to wall surfaces of steel,masonry (poured concrete, concrete block, or cinder block),and plaster or gypsum wallboard. The tests that are listed inTables 1 and 2
4、are designed to measure performance proper-ties. These tests may not all be required for each HIPACsystem. Selection of the test methods to be followed must begoverned by experience and the requirements in each indi-vidual case, together with agreement between the purchaserand the seller.1.2 High-pe
5、rformance architectural coatings are tough,extra-durable organic coating systems that are applied as acontinuous (seamless) film and cure to a hard finish. The finishcan be high gloss, semigloss, or low gloss as desired. Thesecoatings are resistant to persistent heat, humidity, abrasion,staining, ch
6、emicals, and fungus growth. They are used in areaswhere humidity, wear, or unusual chemical resistance require-ments, particularly to soiling, are required and where strongdetergents are used to maintain sanitary conditions. Halls andstairways in public buildings, lavatories, stall showers, lockerar
7、eas, animal pens, and biological laboratories are typicalapplications. In addition, food processing plants, dairies, res-taurants, schools, and transport terminals frequently useHIPAC systems. These are effective in many areas of buildinginteriors compared with tile and are of low materials andmaint
8、enance costs. They are used as a complete system only asrecommended by the manufacturer since the individual coats ina system are formulated to be compatible with each other.HIPAC systems should be applied only to properly preparedsurfaces such as steel or masonry, including cinder blocks andcement
9、blocks. They can be applied over plaster and gypsumwallboard. Ordinarily, a prime or fill coat, if required, is part ofthe system.1.3 While they are excellent for walls, HIPAC are notusually intended for ceilings and floors. They would notordinarily be used in homes, although parents with smallchild
10、ren might want to use HIPAC coatings on some walls.1.4 The types of resin ordinarily used are the following:epoxy-polyamide, two-package; polyester-epoxy, two-package; polyurethane, one-package or two-package. How-ever, other resin types are not excluded provided they can meetthe requirements (perfo
11、rmance specifications) laid down by thepurchaser.1.5 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.6 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibil
12、ity of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

ASTM standard conditions forlaboratory testing are 73.5 6 3.5F (23 6 2C) and 50 6 5%relative humidity.5. Sampling5.1 Prio
42、r to sampling, establish the condition of the con-tainer since damage to it may cause evaporation, skinning, orother undesirable effects. Excessive storage time and tempera-ture fluctuations may cause settling or changes in viscosity.5.2 Sample in accordance with Practice D 3925. Determinethe densit
43、y in pounds per gallon (kilograms/litre) in accordancewith Test Method D 1475. Continue sampling and determiningdensity until successive results agree within 0.1 lb (45 g) or asagreed upon between the purchaser and seller. Then takesamples for testing.5.3 Specify the amount required for a representa
44、tive sample,the package sizes, and an identification code. A 1-U.S. gal (or4-L) sample is usually sufficient for the recommended tests, butfor guidance in selecting a sampling plan consult PracticeE 105.6.

47、 and humidity.7. Liquid Coating Properties7.1 SkinningCoatings that contain a binder that dries byoxidation may be subject to skin formation in a partially filledcan. Since skins are insoluble in the material they must beremoved before use. The referenced test in a partially filledcontainer indicate
48、s the tendency of the material to skin. Atypical minimum time for skinning in accordance with thismethod is 48 h. Examine the original sample for skins, both onand below the surface. Using a well-mixed skin-free portion ofthe sample, perform a skinning test in accordance with GuideD 154, Section 10.
49、7.2 Condition in ContainerThickening, pigment settling,and separation are undesirable and objectionable if a coating,after storage, cannot be readily reconditioned and made suit-able for application with a reasonable amount of stirring.
