This standard deals with dry heat tests applicable both to heat-dissipating and non heat-dissipating specimens

These factors include typical job portfolio that is printed on a particular printing device

performance and critical dimensions necessary for interchangeability and compatibility with other components

It is therefore essential that these systems are carefully maintained to ensure instant readiness when required
