Heat generated by a reacting liquid encapsulating compound has the potential to cause damage to heat-sensitive electronic components. Degradation of the encapsulating compound has the potential to also occur at high temperatures. Proper selection of an encapsulating compound includes knowledge of its exothermic temperature to preclude damage to components.Since the exothermic temperature of a reacting encapsulating compound varies with the volume and geometry of material, it is essential that the volume and geometry be specified in any determination. Select the appropriate volume and geometry. The exothermic temperature is measured in sufficiently precise and reproducible form to allow for application evaluation, quality control, and encapsulating compound characterization.Exothermic temperature rise of two different volumes of the same material using the same geometry indicates the effect of volume. Materials may be compared by testing equal volumes of each material using the same geometry.1.1 This test method provides results that are related to the maximum temperature reached in a specific volume by a reacting liquid encapsulating compound, and the time from initial mixing to the time when this peak exothermic temperature is reached.1.2 This test method provides a means to measure the peak exothermic temperature of an encapsulating compound.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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements see Section 8.Note 1There is no equivalent IEC standard.

4.1 This standard primarily addresses encapsulant products for residential and child-care facilities. It may also be appropriate for some commercial buildings.4.2 Encapsulation provides a means of protecting occupants from exposure to lead in paint in buildings that are likely to remain standing for a long period of time. This nondestructive abatement strategy is useful in situations in which the primary structure needs to remain intact for either historical or economic reasons. Encapsulation offers an abatement strategy that may be more cost effective than abatement by removal of the paint.4.3 There are many environmental and use conditions that affect leaded paint liquid coating encapsulation products, and different types of liquid coating encapsulation products have been developed specifically to meet the requirements of the various conditions. Product types include non-reinforced liquid coatings, as well as products for interior or exterior use. These products may be applied over many different surfaces coated with one or more layers of leaded paint and possibly other coatings. Encapsulation products in service are subjected to many kinds of wear. Various colors and finishes are also available. This guide is intended to assist the purchaser in determining which product is most appropriate for the specific conditions under which the product will be used.4.4 As described in this guide, an encapsulation product must be compatible with the surface to which it is applied. An encapsulation product must bond to the surface coating, and not cause the subsurface layers to separate or deteriorate.1.1 This guide is intended to provide building users such as private building owners, contractors, architects, homeowners, and regulatory authorities with assistance in selecting an appropriate liquid coating encapsulation product for architectural residence and child-care facility use situations for abating leaded paint.
