[CCMC evaluation requirements] CAN/CGSB-11.3-M87, Type 5
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 | CAN/CGSB-11.3-M87, Type 5 |
Title | Hardboard |
Document | Standard |
Publisher | Canadian General Standards Board |
Scope
These evaluations apply to hardboard (Exterior Cladding). Products evaluated demonstrate that they meet the requirements of CAN/CGSB-11.3-M87, “Hardboard,” for hardboard without a factory-applied finish.
Proponents provided evidence that the products manufactured at their plant are of a quality equal to or greater than the level represented by the sample tested and evaluated.
The following requirements are for a Type 5 product
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):

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, in compliance with CAN/CGSB-11.3-M87, Section 6.2, packaging must be marked with the following information:
- manufacturer’s name or trademark;
- quantity;
- thickness (mm), size (mm) and type; and
- “CAN/CGSB-11.3-M87.”
Where permanently identifying a product is not possible, other forms and methods of identification may be allowed pending review and approval by CCMC. Where applicable, the product must be marked with:
- any necessary user safety information, unless a separate information sheet is provided; and
- any additional information required by applicable acts and regulations.
