ASTM C602-95a

Standard Specification for Agricultural Liming Materials

SCOPE
1.1 This specification covers agricultural liming materials, such as burnt lime (quicklime), hydrated lime, limestone, (calcitic and dolomitic), marl, shells, and byproducts including slag, and other materials.  
1.2 The following precautionary caveat pertains only to the test method portion, Section 8: 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.
