1.1''These test methods cover physical testing of quicklime and hydrated lime, and of limestone not otherwise covered in ASTM standards.2

Note 1:''Quicklime and hydrated lime have a high affinity for moisture and carbon dioxide. Caution should be taken to protect both hydrated and quicklime during sampling, storage, and testing (see Practice C50).
