Anotace textu normy ASTM C470/C470M-15 :
This specification deals with molds for forming concrete test cylinders vertically. Molds shall be constructed in the form of right circular cylinders and have a nominal inside height equal to twice the nominal inside diameter. The following are types of molds covered: reusable molds and single-use molds. Reusable molds shall be made of nonabsorptive materials and shall be tested for water leakage. Single-use molds may be made of sheet metal, plastic, suitably treated paper products, or other materials. These materials shall conform to the following requirements: water leakage, absorptivity, and elongation. The following are additional requirements for the types of single-use molds: plastic mold´wall thickness, bottom design, and material; paper molds´side walls, bottom caps, and waterproofing; and sheet metal molds—metal thickness, bottom design, top edge, and coating. Test for elongation, absorption, and water leakage shall also be performed.

1.1 This specification covers molds for use in forming cylindrical concrete specimens. The provisions of this specification include the requirements for both reusable and single-use molds. Note 1: Sizes included are molds having diameters from 50 mm
[2 in.] to 900 mm [36 in.].
1.2 The 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. The inch-pound units are shown in brackets. 1.4 The following safety hazards caveat
pertains only to the test method described in this specification:
