For a commercial red light therapy bed purchase, site acceptance testing is worth specifying in the contract. The test should reflect the actual operating environment rather than a showroom demonstration. It can cover session timing, control functions, emergency stop operation, noise, surface temperature, pergerakan, light output, and the ability to complete repeated sessions without an unexpected shutdown.
Agree the pass criteria before installation. If acceptance depends on light output, state the measurement method, measurement distance, instrument, and acceptable tolerance. If acceptance depends on software features, list each feature and the expected result. Clear acceptance criteria prevent a dispute in which the supplier says the red light therapy bed works and the buyer says it does not meet the promised specification.
