7 Conformal Coating Standards and Humiseal Laboratory Capabilities

7 - Conformal Coating Standards and Humiseal Laboratory Capabilities

Conformal Coating Standards • 5 Main Types: • International (ISO/IEC) • National (UL, ASTM, BS) • Government (MIL, DEF-Stan) • Trade Association / Industry (IPC) • Company (BMW, Bosch, Siemens)

Conformal Coating Standards International Standard National Standard Government Std Trade / Industry Company IEC 1086 UL 746 E MIL-I-46058 C IPC-CC-830 Siemens 224042001 Performance Safety Spark / Burn Performance Quality Independent Testing No Yes Independent QPL Held No Yes Test Reports Available* Yes Yes No Standards Reference Criteria Tested

Conformal Coating Workmanship • 2 Main Types: • Trade Association / Industry (IPC) • Customer (BMW, Bosch, Siemens) • These Should Determine: – Type of Coating Chemistry (Generic or specific coating) – Aesthetic finish (Bubbles, uniformity, appearance) – Functionality (coverage, thickness) – Keep-out areas
