Leak Test Workload Calculator Calculator
Leak testing protects sealed systems in refrigerators, air conditioners, heat pumps, coils, and compressors before shipment. This calculator converts required leak-test volume into workload hours with an allowance for connection, retest, fixture handling, and quality holds.
What this calculator does
- Calculate leak-test hours required from appliance or HVAC units tested, leak-test rate, and allowance for retest and handling.
- a test engineer needs to size leak-test capacity for a sealed-system production schedule
- Shows leak-test workload hours for the selected sealed-system test volume.
Formula used
- Base leak-test time = units or assemblies leak tested ÷ leak-test throughput rate
- Required leak-test workload = base leak-test time × (1 + retest and handling allowance)
Inputs explained
- Units or assemblies leak tested: undefined
- Leak-test throughput rate: undefined
- Retest and handling allowance: undefined
How to use the result
- Use it for coils, compressors, refrigerators, heat pumps, air conditioners, and charged cabinet assemblies.
- The estimate depends on test method, pressure decay or helium cycle time, fixture count, connection time, reject rate, retest rules, and operator loading.
Common questions
- What throughput rate should I use? Use the average completed test rate for the leak-test station or stand, including normal load and unload time if measured that way.
- Should failed units be included? Yes. Units that fail still consume test time, and retest volume should be included through the allowance.
- Does this calculate leak rate? No. It calculates workload hours; use the refrigeration leak rate calculator to measure leak failures as a percentage.
- How can I use the result? Use it to plan test operators, fixture count, shifts, or whether leak testing will constrain final assembly.
