Scope

These Evaluation Listings apply to Types 1, 2 or 5 listed in Table 1, below. Products evaluated demonstrate that they meet the requirements of either CAN/CGSB-11.3-M87, "Hardboard" for hardboard without a factory-applied finish, or CAN/CGSB-11.5-M87, "Hardboard, Precoated, Factory Finished, for Exterior Cladding" for hardboard with a factory-applied finish. Proponents have evidence that products manufactured at their plant are of a quality equal to or greater than the level represented by the sample tested and evaluated.

Coating appearance No unit The coatings shall be commercially uniform in appearance with no defects due to checking, cracking, pinholing or blistering. The colour coating shall be commercially uniform and provide a reasonable match with the colour specified.
Specular gloss No unit The tolerance shall be within ± 5% of the agreed gloss, when determined with a 60° geometry on a plain sample.
Durability No unit The samples are to be inspected for not more than a slight colour change, no more chalking than that represented by a No. 6° of chalking; there should be no checking, cracking or objectionable fibre-raising.

Footnote 2

The specimen size shall be 75 mm x 150 mm. Three galvanized box nails, 2.87 mm in wire diameter and 6.75 mm in head diameter, shall be driven into the board at intervals of not less than 25 mm. The holding fixture shall consist of a plate with a centred opening, 40 mm in diameter, with a testing speed of 3 mm/min to 4 mm/min.

Return to footnote 2 referrer

Footnote 3

The nail shall be 3.28 mm in wire diameter and 7.14 mm in head diameter, and shall be driven into the specimen 9.5 mm from the edge, so that one-half of the nail is exposed on the other side of the specimen. The load shall be applied perpendicular to the long axis of the nail at a constant speed of 3 mm/min to 4 mm/min until failure occurs. Because galvanized nails may bend in this test, a steel carding pin or a steel drill rod of approximately the same diameter may be used.

Return to footnote 3 referrer

Footnote 4

The moduli of rupture shall be calculated based on the original board thickness. The swell shall be based on the difference in thickness before and after the cycling procedure.

Labelling

The CAN/CGSB-11.3-M87 standard requires that labelling of the product packaging be in conformance with Section 6.2, namely with the following information displayed:

  • manufacturer's name or trademark,
  • quantity contained in package,
  • thickness (mm), size and type,
  • "CAN/CGSB-11.3-M87" and a statement that the product complies with the labelled standard, and
  • "CCMC XXXXX-L," which shall be both visible and legible. Where permanently identifying a product is not possible, other forms and methods of identification may be allowed pending review and approval by a CCMC evaluation officer.

Where applicable, the product shall bear additional information as stated below:

  • any necessary user safety information, unless a separate information sheet is provided; and
  • any additional information required by applicable acts and regulations.

The CAN/CGSB-11.5-M87 standard requires that labelling of the product packaging must be in conformance with Section 6.2, namely with the following information displayed:

  • supplier's name,
  • style of cladding component,
  • finish of cladding component,
  • colour of coating,
  • quantity (for siding panels this is expressed in terms of effective coverage),
  • "CAN/CGSB-11.5-M87" and a statement that the product complies with the labelled standard, and
  • "CCMC XXXXX-L," which shall be both visible and legible. Where permanently identifying a product is not possible, other forms and methods of identification may be allowed pending review and approval by a CCMC evaluation officer.

Where applicable, the product shall bear additional information as stated below:

  • any necessary user safety information, unless a separate information sheet is provided; and
  • any additional information required by applicable acts and regulations.
