Loading Procedures

1.Test Simulators

• Description: Test simulators have thermal characteristics similar to most foods, which typically contain 80% to 90% water, fibrous material, and salt.
• Specifications: The simulator is a plastic container (such as polyethylene) of at least 473 ml (1 US liquid pint) volume, filled with a sponge material saturated with a heat transfer solution consisting of a 50/50 ±2% mixture (by volume) of propylene glycol and distilled water.
