[CCMC evaluation requirements] CSA O112.7-M1977 (R2006), Type 1
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 O112.7-M1977 (R2006), Type 1 |
| Title | Resorcinol and Phenol-Resorcinol Resin Adhesives for Wood (Room and Intermediate Temperature Curing) |
| 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.
Resorcinol and phenol-resorcinol resin adhesives must be used for the bonding of wood at temperatures below 85°C for structural laminates, general construction, marine applications, and to bond wood and certain non-wood materials to wood, where a high-strength and waterproof bond is required.
These adhesives may be furnished as a liquid with a separate hardener or catalyst, or as a powder with a separate hardener or catalyst.
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 |
|---|---|---|
| Insoluble material | % | ≤ 20 by mass |
| Amylaceous matter | – | No indication of the presence of amylaceous matter |
| pH of cured film | – | 2.5 ≤ pH ≤ 11.0 |
| Shear strength – compression loading | MPa | ≥ 19 average shear strength |
| Plywood shear strength (dry) | kPa | ≥ 2 800 average shear strength |
| Plywood shear strength (cold soak) | kPa | ≥ 2 800 average shear strength |
| Plywood shear strength (boil) | kPa | ≥ 2 800 average shear strength |
| Liquid working life at 21°C to 24°C | hours | ≥ 3 Footnote (1) |
| Storage life – after six months at 21°C to 24°C | – | Meets the requirements of CSA O112.7 Footnote (2) |
| Delamination (Type II only) | % | ≤ 8 of the total length of all adhesive lines |
| Creep ( environment “A”: 71°C, ambient RH for seven days) | mm | ≤ 3.63 total for two specimens combined for each environment |
| Creep ( environment “B”: 26.7°C, 90% RH for seven days) | mm | ≤ 3.63 total for two specimens combined for each environment |

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.
Additionally, 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.
