This test method covers the determination of temperature of freshly mixed hydraulic-cement concrete. The values stated in inch-pound or SI units are to be regarded separately as standard. Within the text@ SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore@ each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The text of this standard references notes and footnotes that provide explanatory information. These notes and foot notes (excluding those in tables and figures) shall not be considered as requirements of this standard. 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. (Warning-Fresh hydraulic cementations mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure@2) * A Summary of Changes section appears at the end of this standard. 2 Section on Safety Precautions@ Manual of Aggregate and Concrete Testing@ Annual Book of ASTM Standards@ Vol 04.02
