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 moldwall thickness, bottom design, and material; paper moldsside 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 refers to notes and footnotes that 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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and the values from the two systems shall not be combined.

1.4 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.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
