[CCMC evaluation requirements] CSA O112.9-10

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

Scope

Evaluations to this performance-based standard cover "exterior exposure" adhesives. Exterior exposure adhesives are used primarily to bond solid wood to solid wood material in structural wood products such as in laminated lumber, edge-glued lumber, and finger-joined lumber designed for wet or exterior service conditions. Adhesives for exterior use include those subjected to repeated wetting and drying and continuous use under high humidity, but do not include those used in below-ground, ground-contact, and marine uses. This standard is not restricted to a specific type of adhesive.

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):

Performance requirements for physical properties of adhesives for structural wood products (exterior exposure)

Installation requirements

The CCMC requires that evaluation holders provide instructions for the installation of the product(s) that:

Manufacturing requirements

The CCMC requires that evaluation holders, at a minimum, demonstrate that the associated production process:

Labelling requirements

The CCMC requires that evaluation holders ensure that product labels:

Additionally, the CCMC requires that each container bear a label or marking with the following information:

  • manufacturer’s name and lot number;
  • product name;
  • quantity in the container;
  • expiry date after which the material should not be used when stored according to the manufacturer’s instructions; and
  • brief instructions as to the storage and care of the material prior to use.
