APPENDIX C:
POOL AND SPA CODES AND STANDARDS
Pool and spa equipment must be installed in accordance with model codes and installation
standards. These codes require these products to be listed and labeled in accordance with
applicable product standards.
UL standards are typically identified as Standards for Safety and cover reasonably foreseeable
risks associated with a product. Limitations applicable to the products covered by the standard
are delineated in the Scope section of the standard. UL standards are intended to:
Identify requirements for evaluation of products and provide consistency in the
application of these requirements.
Provide guidance for development of products by manufacturers.
Provide requirements compatible with nationally recognized installation codes
An UL Outline of Investigation is a document that contains the construction, performance, and
marking criteria used by UL to investigate a product when the product is not covered by the scope
of an existing UL Standard for Safety. Outlines are not consensus documents and do not require
review by an UL Standards Technical Panel (STP) or other external group.
