Preference is given to the use of performance criteria measurable by examinatio

10、n or testing in NSF Standards development when such performance criteria may reasonably be used in lieu of design, materials, or construction criteria. The illustrations, if provided, are intended to assist in understanding their adjacent standard requirements. However, the illustrations may not inc

NOTE 1 Management system: set of interrelated or interacting elements of an organization to establish policies and objectives and processes to achieve those objectives. A mana

23、gement system can address a single discipline or several disciplines (e.g. quality, environment, occupational health and safety, energy, financial management). The system elements include the organizations structure, roles and responsibilities, planning and operation, performance evaluation and impr

24、ovement. The scope of a management system can include the whole of the organization, specific and identified functions of the organization, specific and identified sections of the organization, or one or more functions across a group of organizations.
