Safety Certifications Are Required For Electric Board Circuits

Keeping electric equipment safe is not just a matter of preventing fire and electrical accidents but also protecting the health and safety of employees who work around them. To help reduce the risk of these hazards, a number of safety certifications exist. Some of these standards are global and some are specific to a particular region.

UL, the Underwriters Laboratory, operates one of the most common global safety mark schemes. The UL logo is usually accompanied by a specific letter that indicates whether the product meets requirements in Canada (C suffix), Australia and New Zealand (A suffix) or the United States (US suffix). Other regional safety marks include the VDE (Germany), CSA (Canada) and the TUV Rheinland Group (Germany).

PCBs are subject to various testing and electric board circuit processes depending on the application for which they are intended. For example, circuits going into medical devices are subject to IEC 60601-1 which sets out standards for protection against fire, electric shock and injury for this type of device. This standard requires a variety of protective measures such as insulation, isolation and limiting voltage and current.

The UL-94 flammability tests of all PCB base materials are another critical test that is important to ensure the safety of electrical boards and components. These tests determine the flame rating and smoke production of a given plastic material and classify it accordingly. PCBs made of FR-4, for example, should be classified as a UL-94 V0 plastic.

Other safety-related tests that are conducted on circuits and end products include arc flash tests and hazard assessments. These assess the dangers of working around an energized circuit and suggest appropriate precautions to prevent hazards such as arcing between conductors, which can be fatal.

It is important to regularly inspect and maintain electrical equipment to identify any potential hazards that may arise. This can be done through a combination of employee training, promoting hazard reporting and fostering a culture of shared responsibility for workplace safety. It is also necessary to implement a process called an Energized Work Permit for any work performed on energized circuits that are exposed to potential hazards. This process brings in task-specific risk analysis and work controls and requires management sign-off to authorize the work.

Lastly, the use of safety labels on breaker panels is crucial to warning workers of dangers and helping them to comply with equipment specifications and relevant regulations. These labels can indicate hazard levels, describe any approach restrictions and list emergency contact information. They can also serve to identify which panel a breaker belongs to, making it easier for employees to locate a breaker in the event of an accident or emergency. Using a PCB manufacturer that is UL certified is the best way to ensure that all your electric equipment complies with applicable safety standards. This can protect your employees from dangerous situations and ensure the quality of your products. Sierra Circuits is a UL-certified PCB manufacturer that can make sure all of your electronic equipment is up to scratch.
