[CCMC evaluation requirements] ASTM D4637/D4637M-15, Type I

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 ethylene propylene diene terpolymer (EPDM) intended for use in single-ply roofing membranes exposed to the weather. The sheet may be non-reinforced, fabric- or scrim-reinforced, or fabric-backed vulcanized rubber sheet.

The sheet shall be formulated from EPDM polymers and other compounding ingredients. EPDM shall be the principal polymer used in the sheet and shall be greater than 95% of the total polymer content.

The standard classifies the membranes into three types of products:

  • Type I - non-reinforced;
  • Type II - scrim (or fabric) internally reinforced; and
  • Type III - fabric-backed.

The following evaluation requirements are for a Type I 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):

Material requirements
Property Unit Requirements

Static puncture resistance pass @ 20 kg
Elongation, ultimate % ≥ 300
Tensile set % ≤ 10
Tear resistance kN/m ≥ 26.27
Brittleness point °C ≤ –45
Ozone resistance no cracks
Heat aging – tensile strength MPa ≥ 8.3
Heat aging – elongation, ultimate % ≥ 200
Heat aging – tear resistance kN/m ≥ 21.9
Heat aging – linear dimensional change % ≤ ± 1
Water absorption mass % ≤ +8, –2 of original
Weather resistance – visual inspection no cracks or crazing
Weather resistance – PRFSE Footnote (1) % ≥ 30
Weather resistance – elongation, ultimate % ≤ 200

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 sheet shall be identified on the side intended to be exposed to the weather with the following information:

  • the ASTM designation number (Specification D4637) and ASTM type; and
  • the the name of the manufacturer or supplier.

The containers holding the product shall be suitably marked to show the following information:

  • the name of the material;
  • the stock and lot numbers;
  • the ASTM designation number and type;
  • the size and quantity as defined by the contract or order; and
  • the name of the manufacturer or supplier.
