Description
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 Sections 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 Sections 1 through 8, the requirements of both sections shall be met unless otherwise specified in the requirements of the subsequent section.
Purpose
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.
