Polyethylene Pipe and Fittings for Water-Based Ground-Source Geothermal Heat Pump Systems

Published by: 2017-01-02 / 2017-01-02 / 20 pages
This Standard establishes the minimum physical and performance requirements for plastic piping system components. These criteria were established for the protection of property, public health and the environment.

The physical and performance requirements in this Standard apply to plastic piping system components as well as non-plastic components of the ground loop heat exchanger including, but not limited to, pipes and fittings used in water-based ground-source heat pump systems. This Standard is intended for ground loop heat exchangers with a maximum temperature and pressure of 140 °F (60 °C) at 100 psi. Water-based ground-source heat pump systems commonly include the use of anti-freeze, heat transfer fluids or other chemical additives. This Standard does not cover refrigerant based ground loop heat exchangers such as direct expansion (DX) systems. This Standard does not cover hydronic heating or cooling systems within buildings.

Drinking water treatment units – Health effects

Published by: 2016-08-14 / 2016-08-14
It is the purpose of this Standard to establish minimum requirements for materials, design and construction, and performance of point-of-use and point-of-entry drinking water treatment systems that are designed to reduce specific health-related contaminants in public or private water supplies. Such systems include point-of-entry drinking water treatment systems used to treat all or part of the water at the inlet to a residential facility or a bottled water production facility, and includes the material and components used in these systems. This Standard also specifies the minimum product literature and labeling information that a manufacturer shall supply to authorized representatives and system owners, as well as the minimum service-related obligations that the manufacturer shall extend to system owners.

The point-of-use and point-of-entry systems addressed by this Standard are designed to be used for the reduction of specific substances that may be present in drinking water (public or private). These substances are considered established or potential health hazards. They may be microbiological, chemical, or particulate (including filterable cysts) in nature. It is recognized that a system may be effective in controlling one or more of these contaminants, but systems are not required to control all. Activated carbon filter systems covered by this Standard are not intended to be used with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

Drinking Water Treatment Units – Aesthetic Effects

Published by: 2016-08-14 / 2016-08-14
It is the purpose of this Standard to establish minimum requirements for materials, design and construction, and performance of drinking water treatment systems that are designed to reduce specific aesthetic-related (non-health effects) contaminants in public or private water supplies. This Standard also specifies the minimum product literature and labeling information that a manufacturer shall supply to authorized representatives and system owners as well as the minimum service-related obligations that the manufacturer shall extend to system owners.

The point-of-use and point-of-entry systems addressed by this Standard are designed to be used for the reduction of specific substances that may be present in drinking water (public or private) considered to be microbiologically safe and of known quality. Systems covered under this Standard are intended to reduce substances affecting the aesthetic quality of the water or to add chemicals for scale control, or both. Substances may be soluble or particulate in nature at concentrations influencing public acceptance of the drinking water. It is recognized that a system may be effective in controlling one or more of these substances but is not required to control all. systems with components or functions covered under other NSF or NSF/ANSI standards or criteria shall conform to the applicable requirements therein.

Personal Care Products Containing Organic Ingredients

Published by: 2016-08-08 / 2016-08-08 / 66 pages
This Standard specifies materials, processes, production criteria, and conditions that shall be met in order for personal care products to make organic label and marketing claims under this Standard. This Standard intends to address products with a minimum organic content of 70% (O70).

Products intended to be labeled with organic processing claims currently defined under the USDA National Organic Program (NOP), including “100% Organic”, “Organic”, and “Made with Organic”, are not covered by this Standard.

Items covered by this Standard include, but are not limited to: cosmetic products; rinse-off and leave-on personal care products; oral care products; and personal hygiene products. These products may be applied to or used externally on any part of the body (e.g., hair, face, hands, and feet). For the purposes of this Standard, cosmetics are considered personal care products.

This Standard does not ensure accuracy of claims specifying a product as “safer”, “better” or of a specific quality.

Like USDA National Organic Program3 (NOP) regulations, this Standard includes allowances and restrictions on processes, agricultural ingredients, and methods of extraction based on the specific label claim to be made on the final product. The organic claim is a process claim, not a product claim. Testing will not necessarily determine whether or not a product is organic or meets this Standard.

Product compliance with this Standard does not ensure compliance with all regulatory requirements.

Drainfield Trench Product Sizing for Gravity Dispersal Onsite Wastewater Treatment and Dispersal Systems

Published by: 2017-01-21 / 2017-01-21 / 34 pages
This Standard provides a methodology to compare, assess and document product sizing criteria for
alternative or proprietary products with respect to conventional coarse aggregate used in onsite
wastewater dispersal drainfields, based on comparative hydraulic performance.


The comparative treatment performance of alternative products compared to performance of conventional
systems is not within the scope of this Standard.

Onsite residential and commercial water reuse treatment systems

Published by: 2016-08-26 / 2016-08-26 / 56 pages
This Standard contains minimum requirements for onsite residential and commercial water treatment
systems. Systems may include the following.

  • Graywater treatment systems having a rated treatment capacity up to 5,678 L/day (1,500 gal/day).
    This applies to onsite residential and commercial treatment systems that treat graywater, those that
    treat laundry water from residential laundry facilities, and those that treat bathing water. See 8.1 for
    performance testing and evaluation.
  • Commercial treatment systems — this applies to onsite commercial treatment systems that treat
    combined commercial facility wastewater and commercial facility laundry water of any capacity, and
    those treatment systems that treat graywater from commercial facilities with capacities exceeding 5,678
    L/day (1,500 gal/day). These systems shall be performance tested and evaluated at the location of the
    reuse system installation, using the wastewater generated onsite from the facility serving the treatment
    system. See 8.3 for performance testing and evaluation. The key elements of a field evaluatin of a
    commercial treatment system are described in Annex A.

Management methods and end uses appropriate for the treated efflent discharged from onsite residential
and commercial treatment systems meeting Class R (single family residential) or Class C (multi-family and
commercial facilitiesds) requirements of this Standard include indoor restricted urban water use, such as
toilet and urinal flushing, and outdoor unrestricted urban water use, such as surface irrigation. Effluent
quality criteria consistent with these uses are described in 8.6, Criteria.

This Standard is intended to address public health and environmental issues. Actual performance for any
site or system may vary, depending on variations in raw water supply (such as alkalinity and hardness),
wastewater constituents, and patterns of use. The end use of the effluent is the responsibility of the owner,
design professionals, and regulatory officials.

System components covered under other NSF or NSF/ANSI standards or criteria shall also comply with the
requirements therein. This Standard shall in no way restrict new system designs, provided such designs
meet the minimum specifications described herein.
