[CCMC evaluation requirements] CSA O112.9-04
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
| Number | CSA O112.9-04 |
| Title | Evaluation of Adhesives for Structural Wood Products (Exterior Exposure) |
| Document | Standard |
| Publisher | CSA Group |
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.
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):
| Property | Unit | Requirement |
|---|---|---|
| Anti-fungal properties Footnote (1) | – | No indication of the presence of fungal growth |
| pH of cured adhesive film | – | 3.0 ≤ pH ≤ 11.0 |
| Creep resistance |
mm | ≤ 0.05 for any specimen |
| mm | ≤ 0.25 maximum average | |
| Creep resistance |
mm | ≤ 0.6 for any specimen |
| mm | ≤ 2.9 maximum average |
| Property | Unit | Hardwood Requirement | Softwood Requirement |
|---|---|---|---|
| Dry | MPa | ≥ 19 | ≥ 10 |
| After vacuum-pressure | MPa | ≥ 11 | ≥ 5.6 |
| After boil-dry-freeze | MPa | ≥ 6.9 | ≥ 3.5 |
| Property | Unit | Hardwood Footnote (1) Requirement | Softwood Footnote (1) Requirement | ||
|---|---|---|---|---|---|
| _ | Lower quartile | Median | Lower quartile | Median | |
| Percent wood failure (dry) | % | 15 | 60 | 75 | 85 |
| Percent wood failure (wet) | % | 55 | 80 | 75 | 85 |
| Delamination resistance | % | Hardwood | ≤ 1.6 | Softwood | ≤ 1 |
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.

Installation requirements
The CCMC requires that evaluation holders provide instructions for the installation of the product(s) that:
- do not contravene the National Building Code of Canada, or any provincial or territorial building codes; and
- meet the requirements of CCMC minimum documentation requirements.
Manufacturing requirements
The CCMC requires that evaluation holders, at a minimum, demonstrate that the associated production process:
- is operated under a documented quality system; and
- meets the minimum requirements of the CCMC minimum documentation requirements.
Labelling requirements
The CCMC requires that evaluation holders ensure that product labels:
- reference the associated CCMC number or mark; and
- meet the requirements of CCMC minimum documentation requirements.
