Safety Certification – Demand安全认证的必要性

Demand for UL’s PWB Recognition Program is driven by end product hazards:

• Fire• Electric Shock• Personal Injury• Environmental Concerns

UL PWB Recognition is used to:

• Characterize the PWBs physical, electrical, flammability and thermal behavior

• Provide guidance for end-use safety design

• Typically allows for less testing during the end product evaluation
