ASTM C470/C470M-08

Standard Specification for Molds for Forming Concrete Test Cylinders Vertically

ABSTRACT
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 moldsspan class=unicode>—metal thickness, bottom design, top edge, and coating. Test for elongation, absorption, and water leakage shall also be performed.
SCOPE
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 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.
1.3 The following safety hazards caveat pertains only to the test method described in this specification: 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.  
1.4 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.

3. General Requirements
3.1 The following provisions apply to both reusable and single-use molds:
3.1.1 Molds shall be constructed in the form of right circular cylinders which stand with the cylindrical axis vertical and the
top open to receive the concrete. They shall be made of materials that do not react with concrete containing portland or other
hydraulic cements. They shall be watertight and sufficiently strong and tough to permit their use without tearing, crushing, or
deforming.
NOTE 2—Reusable lids may be used on molds to reduce moisture loss.
3.1.2 Molds shall have a nominal inside height equal to twice the nominal inside diameter. The diameter of a mold, consisting
of the average of two measurements taken at right angles to each other at the top of the mold, shall not differ from the nominal
diameter by more than 1 %. The height, determined by averaging two measurements taken 180° apart, shall not differ from the
nominal height by more than 2 %. The planes of the top rim of the mold and the bottom shall be perpendicular to the axis of the
