Sealant backer material is available in three types: Type I, Type II, and Type III, and serves one or more of the following purposes: (1) limits the amount and depth of sealant applied to a joint, (2) acts as a barrier interface to prevent backside adhesion (bondbreaker), and (3) provides a form to assist the sealant in developing a shape factor. The material shall be easily compressed and installed in the joint reservoir and shall be heat resistant when used with hot-applied sealants. Physical properties of the material shall conform to the specified requirements for (1) density, (2) tensile strength, (3) water absorption, (3) compression deflection force, (4) compression recovery, (5) heat resistance, and (6) maximum shrinkage.

5.1 This practice is intended solely for the evaluation of metallic-coated, painted metallic-coated, and painted nonmetallic-coated materials used for the manufacture of cold formed framing members.5.2 Correlation and extrapolation of corrosion performance based on exposure to the test environment provided by Practice B117 are not always predictable. Correlation and extrapolation should be considered only in cases where appropriate corroborating long-term atmospheric exposures have been conducted.5.3 This practice assesses whether coated materials not currently in Specification A1003/A1003M satisfy the required minimum corrosion characteristics.1.1 This practice covers procedures for establishing the acceptability of metallic-coated steel sheet, painted metallic-coated steel sheet, and painted nonmetallic-coated steel sheet for use as cold formed framing members.1.2 This practice shall be used to assess the corrosion resistance of different coatings on steel sheet in a laboratory test. It shall not be used as an application performance standard for the cold formed framing members.1.3 The practice shall be used to evaluate coatings under consideration for addition to Specification A1003/A1003M.1.4 The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.1.5 The text of this standard references notes and footnotes that provide explanatory material.
