[CCMC evaluation requirements] ASTM D6878/D6878M-11a

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

Scope

These evaluations apply to flexible sheet made from thermoplastic polyolefin (TPO) as the principal polymer, intended for use in single-ply roofing membranes exposed to the weather. The sheet shall contain reinforcing fabrics or scrims.

The standard specifies that the membrane sheet shall be formulated from ethylene and higher alpha-olefin polymers, copolymers, and mixtures thereof, in amounts greater than 50% by weight of the total polymer content suitably compounded to satisfy the physical requirements in the specification.

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):

Material requirements Footnote (1) Footnote (2)
Property Unit Requirement
Thickness, sheet-overall Footnote (3) mm ≥ 1.0
Thickness, coating over fabric or scrim, weathering side only mm ≥ 0.38
Breaking strength N ≥ 976
Elongation at reinforcement break % ≥ 15
Tearing strength N ≥ 245
Brittleness point °C ≤ –40
Ozone resistance (visual inspection) n/a no cracks
Retention of properties after heat aging – breaking strength % ≥ 90
Retention of properties after heat aging – elongation at reinforcement break % ≥ 90
Retention of properties after heat aging – tearing strength % ≥ 60
Retention of properties after heat aging – weight change (mass) % ≤ ±1
Linear dimensional change % ≤ ±1
Water absorption (mass increase) Footnote (4) % ≤ ±3
Factory seam strength N ≥ 290
Weather resistance (visual inspection) n/a no cracks or crazing

Additional information

If stated in the Listing, the proponent has provided information related to:

Fire classification of roof covering

The membrane was tested in accordance with CAN/ULC-S107-10, “Standard Methods of Fire Tests of Roof Coverings.”

Fire-resistance rating

The membrane used in a roofing assembly was tested in accordance with CAN/ULC-S101-14, “Standard Method of Fire Endurance Test of Building Construction and Materials.”

Wind uplift resistance of membrane-roofing assemblies

The membrane used in a roofing assembly tested in accordance with CAN/CSA-A123.21-10, “Dynamic Wind Uplift Resistance of Membrane-Roofing Systems.”

Installation requirements

The CCMC requires that evaluation holders provide instructions for the installation of the product(s) that:

Manufacturing requirements

The CCMC requires that evaluation holders, at a minimum, demonstrate that the associated production process:

Labelling requirements

The CCMC requires that evaluation holders ensure that product labels:

Additionally, the containers holding the rolled material must be suitably marked to show the following information:

  • the name of the material;
  • the product code;
  • the ASTM number;
  • size and/or quantity; and
  • the name of the manufacturer or supplier.
