[CCMC evaluation requirements] CAN/ULC-S705.1-15

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 spray-applied, rigid polyurethane foam of medium density intended for use as thermal insulation for both building and non-building applications, whether applied on a building site or in a prefabrication (manufacturing) process. This material is also known as foamed in-situ insulation. The continuous-use temperature is within the range of –60°C to +80°C.

For compliance to CAN/ULC-S705.2, users should contact the third-party organization that has been identified by the foam manufacturer as the third party operating the site quality assurance program (SQAP) for the foam product (see product Listing).

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):

Labelling

In compliance with CAN/ULC-S705.1-15, each liquid component container must be identified as either the polymeric isocyanate component (“A”) or the resin component (“B”). The polymeric isocyanate component must be marked with the following information:

  • supplier’s name;
  • material name;
  • type of material (e.g., closed cell spray applied medium density);
  • net mass of the contents of the containers;
  • country of manufacturer; and
  • lot number.

The resin component must be marked with the following information:

  • supplier’s name;
  • material name;
  • type of material (e.g., closed cell spray applied medium density);
  • net mass of the contents of the containers;
  • manufacturing location;
  • lot number;
  • date of manufacture;
  • expiry date;
  • means to identify the installed material;
  • CAN/ULC-S705.1;
  • LTTR (50 mm) RSI X.XX; and
  • The statement “required to be installed according to CAN/ULC-S705.2.”

The label must include a reference to the associated CCMC number.
