ASTM D75-09 ASTM International / 01-Jun-2009 / 6 pages
This ASTM D75-09 practice covers sampling of coarse and fine aggregates for the following purposes:
Preliminary investigation of the potential source of supply,
Control of the product at the source of supply,
Control of the operations at the site of use, and
Acceptance or rejection of the materials
Note 1 – Sampling plans and acceptance and control tests vary with the type of construction in which the material is used.
1.2The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
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.
1.4 ASTM D75-09, 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.
Note 2 – The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Practice D 3666 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice ASTM D 3666 alone does not completely assure reliable results. Reliable results depend on many factors; following the suggestions of Practice D 3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
