Federal law, the Virginia Graeme Baker Pool and Spa Safety Act, requires suction fittings and suction fitting assemblies meet a safety and performance standard, ANSI/APSP-16. APSP released an update to this standard in 2017. Currently the CPSC is reviewing the update changes to the standard and considering updating the federal law. The 2017 version includes certain changes that will have an impact on currently certified products.
With the requirement and method changes, what are key updates manufactures need to be aware of and how it will impact their products? What are these differences and how will a manufacturer know when they need to retest to verify conformance?
Although APSP-16 has test methods in the standard, it cannot be completely prescriptive in test setup as some flexibility is needed when dealing with different product designs and testing equipment. The intent of a labs approach is critical when testing products as variability can have significant impacts on results. When the test method in APSP-16 is not specific, how can changes in test setup and procedures create significant variances in results and flow ratings.
