[CCMC evaluation requirements] ASTM C1311-10

From: National Research Council Canada

This document provides a summary of the minimum requirements imposed by the Canadian Construction Materials Centre (CCMC) for all evaluations based on the below criteria document. Additional requirements may be imposed by the CCMC when necessary for a particular evaluation, and are detailed in the individual evaluation.

Criteria document


These evaluations apply to the properties of a one-component solvent release sealant for use in building construction. These sealants are generally formulated to withstand a maximum joint movement of 7.5% in extension and 7.5% in compression of the nominal joint width.

This specification describes solvent release sealants for general caulking and sealing operations in building construction. However, it should be recognized by the user that not all sealants meeting this specification are suitable for all applications and all substrates and that there is no implication that the sealants are equivalent in all physical properties.

Refer to ASTM C 1193, “Standard Guide for Use of Joint Sealants,” for information on the proper use of sealants meeting this specification.

The standard does not cover detailed requirements for a primer that may be required for the application of the compound to a specific substrate. The indication for and the identification of such a primer will be made by each manufacturer.

Material requirements

The evaluation holder must demonstrate that the product meets the following requirements (additional requirements may be imposed by the CCMC when necessary, and are detailed in the individual evaluation):

General requirements
Property Requirement
Shelf life The sealant in the original container shall be suitable for use for at least 12 months from the date of manufacture when stored at a temperature not less than 5°C (41.0°F) and not more than 27°C (80.6°F).
Colour The colour of the sealant shall be as agreed upon between the purchaser and the manufacturer.
Surface preparation The sealant shall be intended for use only on clean, dry surfaces. When a primer is recommended by a manufacturer for a specific substrate, all tests on that substrate shall include the primer. The proper use of primers (or surface conditioners) with the application of sealants is described in detail in ASTM C 1193, which also describes proper methods for joint design, backup materials, surface preparation, tooling of sealant, and other important procedures in sealant application in buildings.

Physical requirements
Property Unit Requirement
Extrudability s/mL ≤ 9
Indentation hardness - ≤ 50
Bubbling % ≤ 25
Adhesive and cohesive loss cm 2 (in. 2) ≤ 9 (1.5) per substrate
Slump cm (in.) ≤ 0.38 (0.15) per substrate
Stain index - ≤ 3
Tack-free time h ≤ 72
Accelerated Weathering
Edge cracking - ≤ 3
Centre cracking - ≤ 3
Adhesion loss - ≤ 3
Colour change - As agreed


Unless otherwise specified in the contract or order, the sealant shall be packaged in standard commercial containers constructed so as to ensure acceptance by common or other carrier for safe transportation to the point of delivery.

Shipping containers shall be marked with the name, grade, and quantity of the sealant contained therein, as defined by the contract or order under which shipments are made. The name of the supplier and the lot or batch shall also be shown.
