Process media specification

Also known as: media specification

In machine documentation, a process media specification is controlled information defining the properties, limits, compatibility and handling of fluids, gases or other media used by machinery, such as hydraulic oil, coolant, compressed air or cleaning agents.

  • Machine safety
  • Technical documentation

In one sentence

A process media specification defines which fluids and gases a machine may use, within what limits, and how to handle them safely.

Example

A machining center’s specification states compressed air quality and pressure range, the coolant concentration and pH limits, the hydraulic oil grade and which cleaning agents attack the window polycarbonate.

How it applies

  • Machine safety: Media outside the specification can create chemical hazards, fire risk or degraded protection, for example a coolant that clouds a vision panel or a pressure that exceeds a component rating. The limits are part of the machine limits.
  • Technical documentation: Give properties and limits, not only product names, and reference the safety data sheets for handling. Say what the user must check at delivery and during use.
  • Integrated systems: Where media are supplied by the plant (air, water, gas), the specification is an interface requirement between machine builder and operator.
  • Evidence: Keep the specification as a controlled document; changes of medium or supplier go through change control.

Process media specification vs. lubrication specification

A lubrication specification covers lubricants only. A process media specification covers all media the machine uses or processes.
