product safety and quality management 
 
The URS should specify which process parameters need to be controlled or monitored to ensure product safety and quality. It should indicate the frequency of the measurements, the accuracy required, calibration requirements, and the level of reliability which is needed. 
 
The URS should indicate the manner by which product safety and quality data is communicated and archived. Many times, the automation system must communicate with a server-based quality management application. 
 
There may also be specific requirements for paper records, or records managed according to specific standards, that are needed for regulatory compliance. 
 
compliance management 
 
The ways by which data is managed by the automation system to achieve compliance should be stated in the URS. These data management requirements may derive from ISO or industry specific standards mandated by the trade, or from regulatory authorities such as EPA or OSHA. 
 
The URS should state that compliance with NEC and NFPA, as well as local building codes, is required. Specific sections of the NEC or NFPA documents should be highlighted if extra attention is needed for specific situations. There may be local requirements related to ISA-88 batch management or ISA-95 Enterprise-Control System Integration. 
 
Another aspect of compliance are those standards developed by the customer. These could include aspects such as the choice of wire colors, or the use of wire trays as opposed to conduit. There may also be local protocols on equipment and instrument tags, HMI layout, and graphical elements used to symbolize different kinds of process equipment. 
 
Compliance with local or corporate IT standards should be part of the URS document. These aspects normally include how the automation system should be integrated into the local IT architecture, and what is required to ensure cyber security.
