【国外标准】 Standard Practice for Preparing Concrete Blocks for Testing Sealants, for Joints and Cracks

3.1 It is intended that this practice may be used by manufacturers, users, and testing agencies. The use of this practice establishes a uniform procedure for preparing concrete blocks for the testing of sealants. It is not intended to establish test procedures or conditions of test which are associated with each of the joint sealants.1.1 This practice covers the preparation of concrete blocks used for testing of joint and crack sealants for portland cement concrete and asphaltic concrete pavements. There are numerous standard material specifications that use concrete blocks prepared according to this practice. Refer to the specific standard material specification of interest to determine which tests apply and refer to the test methods for each specific test.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes 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.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.
