Standard Specification for Non-Reinforced Liquid Coating Encapsulation Products for Leaded Paint in Buildings
This specification covers minimum material performance requirements and laboratory test procedures for nonreinforced liquid coating encapsulation products (single or multiple-coat systems) for leaded paint in buildings. Three types of nonreinforced liquid coating encapsulation products are presented: type I - encapsulation products intended for interior use, type II - encapsulation products intended for exterior use, and type III - encapsulation products intended for either interior or exterior use. The impact resistance, adhesion, dry abrasion resistance, water vapour transmission, water and chemical resistance, surface burning characteristics, and volatile organic compound content shall be tested to meet the requirements prescribed. Weathering, aging, scrub resistance, mildew resistance, paintability/repairability, flexibility, and tensile properties shall be tested to meet the requirements prescribed.
1.1 This specification covers minimum material performance requirements and laboratory test procedures for non-reinforced liquid coating encapsulation products (single or multiple-coat systems) for leaded paint in buildings. Performance properties addressed in this specification are:
1.1.1 Impact resistance,
1.1.3 Dry abrasion resistance,
1.1.4 Water vapor transmission,
1.1.5 Water and chemical resistance,
1.1.6 Surface burning characteristics,
1.1.7 Volatile organic compound (VOC) content,
1.1.10 Scrub resistance,
1.1.11 Mildew resistance,
1.1.13 Flexibility, and
1.1.14 Tensile properties.
1.2 This specification does not address the selection of an encapsulation product for specific use conditions. Specific use conditions may require performance values other than those stated in this specification. See Guide E1796.
1.3 This specification does not cover the use of corrosion-inhibiting primers prior to encapsulation products on either industrial steel structures or on residential coated metal surfaces. Types of Direct-To-Metal (DTM) primers in conjunction with lead paint encapsulants has not been investigated. Use of primers to yield substrates acceptable to receive an encapsulant, and to inhibit future corrosion of encapsulated substrates, should be evaluated by trial applications at each specific project.
1.4 This specification applies to any non-reinforced liquid applied product that relies primarily on adhesion for attachment to the surface. These products are used to encapsulate a leaded paint surface with the intent of reducing human exposure to lead.
1.5 The results of the test methods included in this specification will not necessarily predict field performance.
1.6 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered 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, 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.
