This voluntary specification establishes the minimum
requirements for dimensional stability, impact resistance,
weatherability, heat resistance, weight tolerance, heat build-
up and lead compound content of rigid polyvinyl chloride
(PVC) exterior profiles used in windows, doors and
skylights. These include:
a) Rigid PVC profiles used as frames, sash and all
structural profiles related to glass retention and/or
profiles that structurally divide lites within a common
master frame of all vinyl products.
b) Rigid PVC profiles as described above, but used in
composite structures where PVC is combined with
other materials such as wood, aluminum, steel,
reinforced thermosets and reinforced thermoplastics.
e) Rigid PVC profiles used as cladding over wood,
aluminum, steel, reinforced thermosets and reinforced
thermoplastics.
These profiles include, but are not limited to, those with
decorative finishes such as paint, laminates and co-extruded
capping compounds.
In this specification, "shall" is used to express a
