为了人们的游泳活动更安全，近40年来NSF通过一系列测试和认证服务——泳池和浴池设备认证项目，满足了各方的需求，包括公众健康检查员、产品制造商、水设施管理者、设施使用者和家庭使用者等。该认证项目包括了NSF/ANSI标准50以及ASTM、ASME等自愿性标准。

NSF/ANSI标准50--泳池、浴池/热浴缸水循环系统部件和相关材料是由其他标准不断发展和合并而来的。此标准适用于产品综合性评估，包括健康影响、性能确认以及安全因素，其安全因素诸如爆炸、持续压力、循环压力、压头损失、降低混浊度、过滤效果、消毒效果、耐久或寿命测试、化学防护、防腐蚀以及电器安全。

NSF标准50应用于硅藻土和滤料层的介质过滤器、过滤器、自动凹型水面掠行艇、离心泵、排水沟、易弯曲的泳池及浴池软管、可调节产出速率的化学进料装置、多出口阀门、流入式化学进料装置以及各类加工设备，包括：内嵌式盐水型电解氯化器、铜或银离子发生器、紫外线系统、臭氧发生器。这些元件和材料被确定应用于公共及居民区内的泳池、浴池或热水管道。NSF将使用其他标准来评估那些还未能在NSF标准50内具有详细测试参数的泳池和浴池产品。下述列举了一些经常被使用到的参考标准和文档：
