[CCMC evaluation requirements] CAN/ULC-S712.1:2017
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
| Number | CAN/ULC-S712.1:2017 |
| Title | Standard for Thermal Insulation – Light Density, Open Cell Spray Applied Semi-Rigid Polyurethane Foam – Material Specification |
| Document | Standard |
| Publisher | ULC Standards |
Scope
These assessments apply to light density, open-cell, spray-applied, semi-rigid polyurethane foam intended for use as thermal insulation for building applications, whether applied on a building site or in a prefabrication (manufacturing) process. This material is also known as "open cell foamed in-situ insulation."
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):
| Property | Unit | Minimum | Maximum |
|---|---|---|---|
| Air permeanse for a 100-mm-thick specimen | L/(s∙m2) @ 75 Pa | No min. | Declare |
| Apparent core density | kg/m3 | 6.8 | 12 |
| Dimensional stability (volume change) at –20°C | % | No min. | –1 shrinkage/+10 growth |
| Dimensional stability (volume change) at 80°C | % | No min. | –15 shrinkage/+10 growth |
| Dimensional stability (volume change) at 70°C, 97 ± 3% relative humidity (RH) | % | No min. | –15 shrinkage/+14 growth |
| Fungi resistance | – | No growth | – |
| Open cell content volume | % | 80 | No max. |
| Surface-burning characteristics – flame-spread rating | – | No min. | 500Table footnote (1) |
| Thermal resistance for a 50-mm-thick specimen | m2·°C/W | 1.20 | No max. |
| Time to occupancyTable footnote (2) (volatile organic emissions) | days | 1 | 30 |
| Water absorption by volume for materials with water vapour permeance (WVP) ≥ 1 400 | % | No min. | Declare |
| Water absorption by volume for materials with 400 < WVP < 1 400 | % | No min. | 50 |
| WVP for a 50-mm-thick specimen | ng/(Pa·s·m2) | 1 400 or 400, depending on water absorption | No max. |

Installation requirements
The CCMC requires that evaluation holders provide instructions for the installation of the product(s) that:
- do not contravene the National Building Code of Canada, or any provincial or territorial building codes; and
- meet the requirements of CCMC minimum documentation requirements.
- requires installation in accordance with CAN/ULC-S712.2:2017
- limits installation to only locations where the continuous service temperature of the substrate is within the range of –60°C to +70°C.
- requires installation to be performed only by installers who can provide, on request, a valid license card, issued by an ISO/IEC 17024 accredited personnel certification body, recognized for licensing spray applied polyurethane foam installers
- includes provisions for the operation of a Site Quality Assurance Program (SQAP) meeting the requirements below.
Manufacturing requirements
The CCMC requires that evaluation holders, at a minimum, demonstrate that the associated production process:
- is operated under a documented quality system; and
- meets the minimum requirements of the CCMC minimum documentation requirements.
Labelling requirements
The CCMC requires that evaluation holders ensure that product labels:
- reference the associated CCMC number or mark; and
- meet the requirements of CCMC minimum documentation requirements.
Additionally, in compliance with CAN/ULC-S712.1, 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:
- the manufacturer’s name;
- the material name;
- the component name;
- the type of material (e.g., light density, open cell);
- the net mass of the contents of the packaged material;
- the country of manufacture;
- the lot number;
- the date of manufacture;
- the “expiry” date;
- the thermal resistance (50 mm) RSI X.XX; and
- the statement “Conforms to CAN/ULC-S712.1.”
