[CCMC evaluation requirements] CAN/ULC-S705.1-01, Amendment: 1 & 2, Type: 2

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


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):

Technical requirements for physical properties

In compliance with CAN/ULC-S705.1-01 (with Amendments 1 and 2), each liquid component container must be identified as either the polyisocyanate component (“A”) or the resin component (“B”). Unless otherwise specified, each container must be marked with the following information:

  • manufacturer’s name;
  • product name;
  • type of material (e.g., insulation);
  • net mass of the contents of the packaged material;
  • country of manufacture;
  • lot number;
  • date of manufacture;
  • “use before” date;
  • the means to identify the installed product; and
  • the phrase “CAN/ULC-S705.1,” indicating conformance to the standard.

The label must include reference to the assocaited CCMC number
