Full Description

1.1This 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:

1.1.1Impact resistance,

1.1.2Adhesion,

1.1.3Dry abrasion resistance,

1.1.4Water vapor transmission,

1.1.5Water and chemical resistance,

1.1.6Surface burning characteristics,

1.1.7Volatile organic compound (VOC) content,

1.1.8Weathering,

1.1.9Aging,

1.1.10Scrub resistance,

1.1.11Mildew resistance,

1.1.12Paintability/repairability,

1.1.13Flexibility, and

1.1.14Tensile properties.

1.2This 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.

1.3This 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.

1.4This 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.

1.5The results of the test methods included in this specification will not necessarily predict field performance.

1.6The 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.

1.7This 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.

1.8This 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.
