Guidelines for Performing a Test Run

There are some considerations and planning that can assist in performing a successful test run. 

A test run involving the actual raw materials for the toll or the initial startup that follows a water batch and PSSR is an appropriate time to evaluate any planned changes necessary for increasing production later in the toll. 

Examining the feasibility of increasing the charging amounts or shortening turnaround times for batches might be the reason for testing. Both of these items can raise issues that potentially affect process safety. 

Some of the pre-startup activities may need to be revisited when physical increases in volume and changes to equipment are planned. A PHA may need to be revalidated prior to implementing such a change to evaluate any secondary issues it could cause.
