See Guide E1796.1.3 This specification complements Specification E1797 for reinforced liquid coating encapsula
6、tion products.1.4 This specification does not cover the use of encapsulation products on industrial steel structures nor on residential coatedmetal surfaces because no corrosion control requirements are included.1.5 This specification applies to any non-reinforced liquid applied product that relies

Performance Requirements5.1 Performance requirements that shall be met for a non-reinforced liquid coating encapsulation product are given in Table 1.NOTE 1In addition to those g
27、iven in Table 1, performance requirements for three other properties are of concern for liquid coating encapsulationproducts. These are combustion toxicity, emissions during application and curing, and lead accessibility. However, requirements for these properties3Available from Standardization Docu

29、 determining them. Requirementsfor two of these properties, combustion toxicity and emissions during application and curing, may be subject to regulations or ordinances promulgatedby authorities having jurisdiction. The user of this specification is advised to determine whether such regulations or o
30、rdinances exist. The additionofrequirements for these properties to this specification will be undertaken when suitable test methods are available.6. Sampling6.1 A 3.8-L (1-gal) sample is usually sufficient for the recommended tests.6.2 Prior to sampling, establish the condition of the container sin
31、ce damage to it may cause evaporation, skinning, or otherundesirable effects. Excessive storage time and temperature fluctuations may cause settling or changes in viscosity. Materialsbeyond the manufacturers stated shelf life shall not be sampled.6.3 Thickening, settling, and separation are undesira
32、ble and objectionable if the coating, after storage, cannot be readily madesuitable for application with a reasonable amount of stirring. Determine the conditions in the container in accordance with Method3011 of the Federal Test Method Standard No. 141C.6.4 Sample the encapsulant in accordance with
33、 Practice D3925. Determine the density in accordance with Test Method D1475and repeat until two successive readings agree within 90 g (0.2 lb). Samples for testing may then be taken.6.5 Report the size of the container from which the sample was taken and product identification codes.7. Number of Tes

Retesting8.1 In cases where encapsulation products fail to pass one or more requirements of this specification, retesting shall bepermitted. Both the original data and the retesting data for each r
35、equirement for which retesting was conducted shall be used indetermining whether the requirement is met.9. Test Specimens9.1 A non-reinforced liquid coating encapsulation product shall be comprised of all principal components in the system,including the base and top coats and primer, if specified, f
36、or field application. Except for adhesion testing and dry abrasion testing,where specialty primers may be used for flash rust resistance, primers shall not be used solely for product performance testing inaccordance with this specification.TABLE 1 Performance Requirements for Reinforced Liquid Coati
