Standard ENStandard Specification for Poly(Vinyl Chloride) Sheet Roofing
Also Known As:
The ASTM D4434/D4434M-21 standard specifies the requirements for flexible sheet materials made from poly(vinyl chloride) resin for use in single-ply roofing membranes exposed to weather conditions. The sheet materials may contain reinforcing fibers or fabrics. The purpose of this standard is to ensure the minimum quality of the sheet materials.
The standard defines various physical requirements that the sheet materials must meet. These requirements include overall thickness and thickness over scrim, tensile strength at break, breaking strength, elongation at break, seam strength, retention of properties after heat aging, tear resistance and tearing strength, low temperature bend, cracking and crazing after accelerated weathering test, linear dimensional change, change in weight after immersion in water, and static and dynamic puncture resistance.
It is important to note that this specification does not cover in-place roof system design criteria such as fire resistance, material compatibility, wind uplift resistance, and in-situ shrinkage. These factors should be considered separately for the specific application.
