This specification covers a lubricant suitable for facilitating the insertion and positioning of preformed elastomeric compression seals in prepared voids (usually contraction joints) in concrete pavements. The lubricant shall be based on polychloroprene, containing only soluble phenolic resins blended together with antioxidants and acid acceptors in a suitable mixture of organic solvents. The requirements of the lubricant are based on the performance of the lubricant as measured by its solids content, homogeneity, consistency and drying rate.1.1 This specification covers a lubricant suitable for facilitating the insertion and positioning of preformed elastomeric compression seals in prepared voids (usually contraction joints) in concrete pavement.1.2 The requirements of the lubricant are based on the performance of the lubricant as measured by its solids content, homogeneity, consistency, and drying rate.1.3 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of U.S. customary units may be approximate.1.4 The following precautionary caveat pertains only to the test method portion, Section 7 of this specification. 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.1.5 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.

This specification covers foaming agents specifically formulated for making preformed foam for use in the production of cellular concrete. The function of this specification is to provide the means for evaluating the performance of a specific foaming agent. The test batch shall conform to the physical requirements prescribed such as density, compressive strength, tensile splitting strength, water absorption and air loss during pumping. The foaming agent being tested shall be used in making test specimens required.1.1 This specification covers foaming agents specifically formulated for making preformed foam for use in the production of cellular concrete.1.2 The function of this specification is to provide the means for evaluating the performance of a specific foaming agent. This is accomplished by using the foaming agent in making a standard cellular concrete test batch (see Test Method C796) from which test specimens are cast. Then, significant properties of the concrete are determined by tests and compared with the requirements of Section 3.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

5.1 Preformed tape sealants are tacky, deformable solids, that are used under compression between two or more substrates, in various sealing applications where the surfaces may be of similar or dissimilar materials. This procedure measures the tensile strength of the preformed tape sealant. It also provides an indication of the cohesive nature and adhesive bonding properties of the preformed tape sealant. This procedure is not intended to simulate actual use conditions.1.1 This test method covers a laboratory procedure for determining the tensile adhesive strength of a preformed tape sealant. The type of failure can be determined, and the degree of cohesive/adhesive failure can be estimated.1.2 The values stated in metric (SI) units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.1.3 The subcommittee with jurisdiction is not aware of any similar ISO standard.1.4 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.1.5 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.

4.1 Tape sealants are tacky, deformable solids that are used under compression between two or more surfaces of similar or dissimilar materials in a variety of sealing applications. This procedure is not intended to simulate an actual use condition but will give some indication of the cohesive and adhesive bonding properties of the tape. It also provides an indication of the modulus and tensile strength of the sealant tape composition.1.1 This test method covers a laboratory procedure for determining the yield strength of preformed tape sealants.1.2 The values stated in acceptable metric units are to be regarded as the standard. The values given in parentheses are for information only.1.3 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.NOTE 1: There are no ISO standards similar or equivalent to this ASTM standard.1.4 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.

This specification covers preformed cranioplasty plates that allow alteration of dimensions to fit a particular skull defect. Cranioplasty plates shall be manufactured from unalloyed titanium, wrought cobalt-20chromium-15tungsten-10nickel alloy, or wrought titanium-6aluminum-4vanadium extra low interstitial alloy with multiple perforations and in various dimensions, with the thickness and shape varying with need. The shape, in particular, may be altered by the neurosurgeon such as to contour it to conform to the normal configuration and symmetry of the skull at various defect sites. Should the plates require metallic sutures or screws as fasteners, they shall be of the same metallic composition as the cranioplasty plates.1.1 This specification covers preformed cranioplasty plates that allow alteration for covering skull defects.
