[CCMC evaluation requirements] CSA O112.6-M1977 (R2006)

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

These evaluations apply to all structural wood adhesives. The prescriptive standards cover phenol and phenol-resorcinol resin adhesives (high-temperature curing), and resorcinol and phenol-resorcinol resin adhesives (room- and intermediate-temperature curing). The performance-based standard covers “exterior exposure” and “limited moisture exposure” adhesives.

Phenol and phenol-resorcinol adhesives and resins must be used as a base for extended adhesives, to be used at temperatures above 85°C for the manufacture of plywood, and to bond wood and certain non-wood materials to wood, where a high-strength, durable, waterproof bond is required. These adhesives may be furnished as a liquid, powder, or film with a separate hardener or catalyst, or filler when required.

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 phenol and phenol-resorcinol resin adhesives for wood (High-temperature curing)
Property Unit Requirement
Insoluble material % ≤ 20 by mass
Amylaceous matter No indication of the presence of amylaceous matter
pH of cured film ≥ 2.5
Plywood shear strength (dry) kPa ≥ 2 500 average shear strength
Plywood shear strength (cold soak) kPa ≥ 2 500 average shear strength
Plywood shear strength (boil) kPa ≥ 2 500 average shear strength
Liquid working life at 21°C to 24°C hours ≥ 3 Footnote (1)
Storage life – after three months at 21°C to 24°C Meets the requirements of CSA O112.6 Footnote (2)

Labelling

The standards require 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.
