[CCMC evaluation requirements] CAN/ULC-S711.1-05, Class 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 thermal insulating bead-applied two-component polyurethane foam. It is intended for use as an insulating air sealant for both building and non-building applications. This two-component polyurethane air sealant is prepackaged at the factory. The continuous-use temperature is within the range of −60°C to +110°C.

The standard referenced below covers bead-applied two-component polyurethane air sealant foam, whether it is applied on a building site or in a prefabrication (manufacturing) process. This standard includes test methods used to determine the material properties and provides a means of comparing different polyurethane air sealant foams. These tests are intended for use in specifications, product evaluations and quality control.

Products conforming to CAN/ULC-S711.1-05 are classified as either Class I or Class II in accordance with their flame-spread value.

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):

Installation requirements

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

Additionally, installation must comply with CAN/ULC-S711.2-05.

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:

In compliance with CAN/ULC-S711.1-05, each container/package must be labelled with the following information:

  • manufacturer’s name and address;
  • product name and class;
  • tested bead width;
  • net mass per container;
  • lot number;
  • date of manufacture;
  • “use before” date; and
  • the phrase “CAN/ULC-S711.1-05” indicating conformance to the standard
