Hygienic Process Liquid Spray Device Specification (Universally Applicable)
This Practice provides the minimum requirements for the specification of spray devices in hygienic processes. Spray devices may include a broad range of designs for process applications. This Practice is intended to address basic requirements that are common for typical applications. The purchaser shall ensure that specifications are invoked and provided for specific applications that exceed the scope of this Practice. The purchaser may also provide data sheets, P&IDs, process data, and any other supplemental specifications needed to define the requirements for specific packaged equipment.
New Practice
Specification for Developing Data Forms for Practices
This Practice provides requirements for developing data forms for Process Industry Practices (PIP). PIP data forms are used to define project-specific requirements and quantities. Data forms include data sheets, inspection and testing requirements sheets (ITRS), and documentation requirements sheets (DRS). This Practice addresses basic editable documents not requiring software development or maintenance. This Practice may be used for any data forms (e.g., checklists) provided with Practices.
