This National Standard of Canada establishes a classification system and specifies physical property requirements. Test methods to determine the properties for each class of polyethylene sheet material are specified. This document covers a material intended to be used in building construction applications, that may be used above grade or in contact with the ground. The material can provide the vapour barrier, air barrier, and/or moisture barrier function, whether installed on a building site or in a prefabrication (manufacturing) facility. The test methods listed in this document are used to determine the values for the material properties. These values are intended for use in specifications, product evaluations and quality control. They are not intended to predict in situ end-use product performance. The polyethylene sheet material is not intended to be used where the continuous service temperature of the substrate or ambient air is outside the range of -60 to +65 °C. Values used in this standard are provided in units from the International System of Units (SI units). Applications and installation requirements are not covered in this standard. Note: This standard is intended to be used in a conformity assessment program. The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This standard does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
