Draft Details

1.1 General

The test method in this Standard determines the wind pressure resistance of photovoltaic roof assembly when subjected to dynamic wind loading cycles induced by actuators in laboratory conditions.

1.2 Inclusions

This Standard applies to photovoltaic arrays with tilt angle no greater than 35o from roof surface, constructed on partially attached (hybrid) or adhesive applied membrane-roofing system (PARS and AARS).

1.3 Exclusions

This Standard is not applicable to photovoltaic arrays constructed on mechanically attached membrane roofing systems (MARS), vegetated roof assemblies (VRA), protected membrane roofs or loose-laid membrane roofing systems.

1.4 Terminology

In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard.

1.5 Units of measure

The values given in SI (metric) units are the standard. The values given in parentheses are for information only
