Thermal container validation protocol

The protocol is written and approved before the test: product range, load and route, sensor rationale, acceptance criterion and deviation path.

Short answer

The protocol is approved before testing and defines five things: the product temperature range, load and route, the rationale for sensor points, the acceptance criterion and the deviation path. A test whose criteria are chosen after the results appear can be read toward the answer everyone wants, so the order is always writing first, measuring second.

A validation protocol is a document written and approved before any result is seen. Its order is:

The product temperature range and how long the container must stay within it.
Load and route: fill, starting temperature, ambient exposure, stops and the worst case for door openings.
Sensor count and positions with a reason for each; alignment of device clocks.
The acceptance criterion.
Who assesses a deviation, and on which records.

An unsuitable result is recorded and the protocol is not rewritten afterwards; work after a correction runs as a new version. GEBHARDT offers process consulting and guided testing for the Isotec TBX, and Aris Makina passes the request on.
