Equipment for Swimming Pools, Spas, Hot Tubs and other Recreational Water Facilities
NSF International / 10-Aug-2011 / 158 pages
This Standard covers materials, components, products, equipment and systems, related to public and
residential recreational water facility operation.
In this edition of NSF/ANSI 50 the following revisions were incorporated:
Issue 57 ? CEC pump, energy and sound testing
This revision included an optional evaluation criteria and testing method for the evaluation of pumps for energy efficiency.
Issue 66 ? Chemical feeders
This revision updated 5 ? Filters to clarify the marking requirements for vacuum service filters to specify the collapse negative pressure in psi or inches of mercury. Sections 5 ? Filters, 9 ? Mechanical chemical feeding equipment and 10 ? Flow-through chemical feeding equipment updated the product data plate to reference a web address and phone number by which users can obtain the installation, operation, and maintenance instructions.
Issue 66 ? Equalizer line
This revision resolved the issue of public pool skimmer equalizer lines required as mandatory or optional. It provides the mechanism for continued production, testing, and certification, and the installation of skimmers equipped with equalizers where permitted or required by code and allows skimmers to be installed without equalizer lines to address jurisdictions and codes that prohibit equalizer lines and the additional submerged suction fittings.
Issue 70 ? Normative Reference and mechanical chemical feeders
The revision added section within 4 to address special use suction fittings (i.e. the vacuum port fittings); updated the normative references; and 9 was revised to allow for mechanical chemical feeding equipment that operates at a fixed rate if it is controlled by a chemical controller that meets the requirements of 17 and the mechanical chemical feeder has a method of mechanically restricting the maximum output per day.
Issue 73 ? Media labeling
This revision added requirements for filtration media labeling.
Issue 76 ? Filtration media reorganization
NSF/ANSI 50 ? 2011 was editorially reformatted to make the Standard more user friendly. A new section for filtration media was created (Section 11). The requirements in 11 – General requirements for process equipment were added to 12 ? Ozone process equipment, 13 ? Ultraviolet light process equipment, 14 ? In-line electrolytic chlorinator or brominator process equipment, 15 ? Brine (batch) type electrolytic chlorine or bromine generators, and 16 ? Copper/silver and copper ion generators.

Sustainability Assessment for Commercial Furnishings Fabric
Published by NSF International in March 2011 (78 pages)
This Standard provides pathways toward sustainability by establishing measurable criteria for multiple levels of achievement. It allows manufacturers flexibility in methods for conformance and certification. This Standard assesses product characteristics in the areas of material and component inputs, water and energy use, recycling practices and social accountability. This version of the Standard does not include specific criteria for calculating carbon footprint nor does it cover transportation.
This Standard is applicable to commercial fabrics commonly used in public occupancy settings, such as office, hospitality, healthcare, and institutional interiors. These include but are not limited to upholstery, vertical fabric (furniture system, wall, drapery, and cubicle), and top of the bed fabrics. Fabrics may be formed by combining yarns, fibers, or filaments in a variety of ways including but not limited to woven, non-woven, knitted, bonded, felted, and composite materials. This Standard is applicable to fabrics manufactured in one or multiple facilities, in one or multiple countries.

Evaluation of components and devices used in wastewater treatment systems
The purpose of this Standard is to establish minimum materials, design and construction, and performance requirements for components and devices used in the handling, treating, recycling, reusing, or disposal of wastewater. This Standard is intended to protect public health and the environment as well as to minimize nuisance factors.
This Standard is intended for use with components and devices not covered by other NSF wastewater standards. Components and devices covered by this Standard are intended for use with greywater or blackwater or both. Management methods for the end-products of these components and devices are not addressed in this Standard. This Standard shall in no way restrict new system designs, provided that such designs meet the minimum specifications described herein.
All devices and components meeting the scope of this Standard shall comply with all of the requirements described in 1 through 8. In addition, devices and components shall comply with the applicable subsequent section(s) contained in this Standard. Where subsequent sections of the Standard include requirements that overlap with those found in 1 through 8, the requirements of both sections shall be met unless otherwise specified in the requirements of the subsequent section.
