This Standard is for the design, equipment and installation of permanently installed residential spas and swim spas and does not cover public spas or factory built residential portable spas.
Major changes from the previous version from 1999 include the addition of permanent inground “swim spas”. The revised standard also includes the latest safety and energy requirements by referencing the latest standards to ensure the highest degree of safety and operating efficiency. For example, a new Appendix B on Water Velocity Limits has been incorporated to assist pool designers and builders on how to determine the required design flow rates, essential to energy efficiency and bather safety.
A downloadable PDF version is also available in the APSP Store.
