NSF International
Drinking Water Treatment Units - Aesthetic Effects
N 42
Annotation
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.
Purpose
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.

Модули обработки питьевой воды - эстетические эффекты
Точка использования и системы точки входа, обращенные этим Стандартом, разработаны, чтобы использоваться для сокращения определенных веществ, которые могут присутствовать в питьевой воде (общедоступный, или частный) считал микробиологически безопасным и известного качества. Системы, покрытые в соответствии с этим Стандартом, предназначаются, чтобы уменьшить вещества, влияющие на эстетическое качество воды или добавить химикаты для управления масштабом или обоих. Вещества могут быть разрешимыми или макрочастица по своей природе при концентрациях, влияющих на общедоступное принятие питьевой воды. Это распознано, что система может быть эффективной при управлении тем или большим количеством этих веществ, но не требуется, чтобы управлять всеми. Системы с компонентами или функциями, покрытыми под другим NSF или стандартами NSF/ANSI или критериями, должны соответствовать применимым требованиям там.
