1、Designation: E1795 17Standard Specification forNon-Reinforced Liquid Coating Encapsulation Products forLeaded Paint in Buildings1This standard is issued under the fixed designation E1795; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revis
2、ion, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers minimum material perfor-mance requirements and laboratory test procedures f
3、or non-reinforced liquid coating encapsulation products (single ormultiple-coat systems) for leaded paint in buildings. Perfor-mance properties addressed in this specification are:1.1.1 Impact resistance,1.1.2 Adhesion,1.1.3 Dry Abrasion Resistance,1.1.4 Water Vapor Transmission,1.1.5 Water and Chem
4、ical Resistance,1.1.6 Surface Burning Characteristics,1.1.7 Volatile Organic Compound (VOC) Content,1.1.8 Weathering,1.1.9 Aging,1.1.10 Scrub Resistance,1.1.11 Mildew Resistance,1.1.12 Paintability/Repairability,1.1.13 Flexibility, and1.1.14 Tensile Properties.1.2 This specification does not address
5、 the selection of anencapsulation product for specific use conditions. Specific useconditions may require performance values other than thosestated in this specification. See Guide E1796.1.3 This specification complements Specification E1797 forreinforced liquid coating encapsulation products.1.4 Th
6、is specification does not cover the use of encapsula-tion products on industrial steel structures nor on residentialcoated metal surfaces because no corrosion control require-ments are included.1.5 This specification applies to any non-reinforced liquidapplied product that relies primarily on adhesi
7、on for attach-ment to the surface. These products are used to encapsulate aleaded paint surface with the intent of reducing human expo-sure to lead.1.6 The results of the test methods included in this specifi-cation will not necessarily predict field performance.1.7 The values stated in SI units are
8、 to be regarded as thestandard. The values given in parentheses are for informationonly.1.8 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices

23、ype I: Interior Use OnlyType I defines encapsulationproducts intended for interior use. These products shall meetthe requirements of this specification except those for weath-ering and exterior aging (that is, test methods described in 10.9and 10.10.1 not conducted).4.2 Type II: Exterior Use OnlyTyp
24、e II defines encapsula-tion products intended for exterior use. These products shallmeet the requirements of this specification except that forinterior aging (that is, test method described in 10.10.2 notconducted).4.3 Type III: Either Exterior or Interior UseType IIIdefines encapsulation products i
25、ntended for either interior orexterior use. These products shall meet all the requirements ofthis specification.5. Performance Requirements5.1 Performance requirements that shall be met for a non-reinforced liquid coating encapsulation product are given inTable 1.NOTE 1In addition to those given in
26、Table 1, performance require-ments for three other properties are of concern for liquid coatingencapsulation products. These are combustion toxicity, emissions duringapplication and curing, and lead accessibility. However, requirements forthese properties cannot be included in this specification at
27、this timebecause there are no adequate ASTM or Federal test methods fordetermining them. Requirements for two of these properties, combustiontoxicity and emissions during application and curing, may be subject toregulations or ordinances promulgated by authorities having jurisdiction.The user of thi
28、s specification is advised to determine whether suchregulations or ordinances exist. The addition of requirements for theseproperties to this specification will be undertaken when suitable testmethods are available.6. Sampling6.1 A 3.8-L (1-gal) sample is usually sufficient for therecommended tests.
29、6.2 Prior 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.Materials beyond the manufacturers stated shelf life shall
30、 notbe sampled.6.3 Thickening, settling, and separation are undesirable andobjectionable if the coating, after storage, cannot be readilymade suitable for application with a reasonable amount ofstirring. Determine the conditions in the container in accor-dance with Method 3011 of the Federal Test Me
31、thod StandardNo. 141C.6.4 Sample the encapsulant in accordance with PracticeD3925. Determine the density in accordance with Test MethodD1475 and repeat until two successive readings agree within90 g (0.2 lb). Samples for testing may then be taken.6.5 Report the size of the container from which the s
32、amplewas taken and product identification codes.7. Number of Tests7.1 The number of tests that shall be conducted for eachperformance property is given in Table 1.8.

If a range of thickness is specified by themanufacturer for field application, the minimum value of thisrange shall be used for product testing in acc
