| Test Objective | Define the ATK test objective, including the function, interface, operating mode, and performance parameters to be verified. | Use an approved test plan with a unique document revision and defined pass/fail limits. | Approved test plan and requirement traceability record. |
| Device Under Test | Record the device configuration, hardware revision, firmware version, accessories, cables, power source, and serial number. | The unit must be free from visible damage and configured exactly as specified by the test plan. | DUT identification sheet and pre-test photographs. |
| Test Environment | Conduct the test in a controlled laboratory area with stable temperature, humidity, supply voltage, and electromagnetic conditions. | Typical laboratory control should be approximately 20–25 °C and 40–60% relative humidity unless the applicable specification states otherwise. | Environmental log recorded before and during testing. |
| Equipment Readiness | Prepare calibrated measurement instruments, test fixtures, programmable supplies, loads, cables, probes, and data-acquisition equipment. | Calibration must be valid on the test date; equipment ranges and accuracy must be suitable for the expected measurement. | Calibration certificates and equipment checklist. |
| Electrical Inspection | Inspect connectors, insulation, grounding, polarity, protective devices, and cable routing before applying power. | Disconnect power while changing wiring. Do not operate equipment with exposed conductors, damaged insulation, or missing protective earth connections. | Electrical safety checklist marked complete. |
| Initial Functional Check | Power up the DUT using the specified sequence and verify indicators, communications, self-test results, and basic operating functions. | Use current-limited power where practical and monitor voltage, current, temperature, and abnormal noise or odor. | Baseline readings and functional check record. |
| ATK Test Sequence | Execute each ATK test step in the approved order, including setup, stimulus, stabilization, measurement, and recovery steps. | Change only one controlled variable at a time and allow the DUT to reach the specified stabilization period before recording results. | Completed test worksheet with time-stamped measurements. |
| Measurement Controls | Record measured values, units, instrument identification, test settings, sample rate, and measurement uncertainty where applicable. | Avoid overloaded inputs, incorrect probe attenuation, open measurement ports, and unverified fixture losses. | Raw data file and instrument setting screenshots. |
| RF or High-Frequency Safety | If the ATK setup includes RF energy or high-frequency signals, control access to the test area and use suitable shielding, interlocks, and warning labels. | Keep personnel outside restricted areas during transmission and follow the applicable occupational exposure limits and laboratory procedures. | RF safety assessment, access-control record, and interlock check. |
| Electrostatic Discharge | Apply ESD controls when handling exposed electronic assemblies, connectors, or sensitive components. | Use a grounded ESD workstation, wrist strap or equivalent personnel grounding method, and suitable ESD packaging. | ESD workstation verification and handling record. |
| Thermal and Mechanical Safety | Monitor surfaces, heat sinks, moving parts, mounting points, and fixture stability throughout the test. | Use guards and thermal protection where necessary. Do not touch hot surfaces or moving assemblies during operation. | Temperature log and fixture inspection record. |
| Abnormal Condition Response | Stop the test immediately if smoke, arcing, excessive current, uncontrolled temperature rise, mechanical failure, or communication loss occurs. | Remove power using the approved emergency procedure and allow safe discharge or cooling before inspection. | Incident report, corrective action, and retest authorization. |
| Repeatability | Repeat critical measurements according to the test plan and verify that the result is consistent within the defined tolerance. | Keep instrument settings, DUT configuration, cable routing, and environmental conditions unchanged between repeats. | Repeatability results and variation analysis. |
| Pass or Fail Decision | Compare each verified result with the approved requirement limit and identify any deviation, uncertainty, or invalid measurement. | A result must not be declared passing when required data, calibration, or test conditions are incomplete. | Requirement Met |
| Test Records | Archive the test plan, setup photographs, instrument list, calibration evidence, raw data, processed results, deviations, and final report. | Protect records from unauthorized changes and retain them for the period required by the applicable quality system. | Controlled test report and data archive. |
