[CCMC evaluation requirements] CSA O112.10-08
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 O112.10-08 |
| Title | Evaluation of Adhesives for Structural Wood Products (Limited Moisture 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.
Adhesives covered by this standard must be used to bond solid wood materials in structural wood products intended for limited moisture exposure applications. “Limited moisture” refers to conditions where the bond line of the adhesive is stressed to design-load levels only when the moisture content of the surrounding wood is 19% or less (dry service). The moisture content of the wood might occasionally be greater than 19% (e.g., due to accidental wetting); however, the wood is not expected to resist design stress levels when wet. Bond lines exposed to moisture content exceeding 19% have comparable performance to unexposed bond lines, provided that the surrounding wood is allowed to return to dry service conditions (“dry service conditions” means the average moisture content does not exceed 15% during the year, and the maximum moisture content is 19% or less).
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 | – | ≥ 2.5 |
| Block shear strength Footnote (2) (dry) | MPa | ≥ 10 |
| Block shear strength Footnote (2) (vacuum-pressure soak/dry) | MPa | ≥ 6.5 |
| Block shear strength Footnote (2) (boil-dry-freeze/dry) | MPa | ≥ 3.7 |
| Delamination resistance | % | ≤ 1 |
|
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 | Requirement | |
|---|---|---|---|
| Lower quartile Footnote (1) | Median Footnote (2) | ||
| Dry | % | 75 | 85 |
| Vacuum-pressure soak/dry or boil-dry-freeze/dry | % | 75 | 85 |

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.
In addition 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.
