Design for Safety

International safety standards are not a final hurdle — they are an engineering foundation. We build compliance into every layer of the design, from the first schematic line.

Why It Matters

Compliance Must Begin at the Design Stage

Many electronics development projects treat regulatory compliance as a post-design activity — something to address once the prototype is working. This approach is costly and risky. When a product fails a safety test late in development, the resulting redesign can affect not just the PCB layout, but the fundamental architecture: the choice of transformer, the clearance between conductors, the protective components, the enclosure design.

At Pabst Electronics, we eliminate that risk by treating the applicable safety standards as design inputs from day one. The engineers who design your product are the same engineers who understand the standards that apply to it. There is no handoff to a compliance consultant at the end — compliance is engineered in from the start.

🔬 We Have Been Inside the Test Lab

One of the most valuable aspects of our safety expertise is something that cannot be learned from reading standards alone: our engineers have followed the execution of IEC and UL compliance tests firsthand. We have observed how dielectric strength tests are performed, how abnormal operation tests are conducted, how temperature rise measurements are taken, and how test engineers interpret borderline results.

That practical, first-hand knowledge of how safety tests are actually executed makes our designs more robust, our test plans more accurate, and our certification process more predictable — saving our clients time and money at the test laboratory.

Standards We Work With

Standards We Have Designed To — and Tested Against

Not certifications we reference — standards we have used as active design inputs on real products, with first-hand test lab experience behind each one.

IEC 61010

Measurement, Control & Laboratory Equipment

IEC 61010 applies to electrical equipment used for measurement, control, and in laboratory environments. It covers overvoltage categories, pollution degrees, insulation requirements, protection against mechanical hazards, and radiation. We have designed products to this standard for industrial instrumentation, process control equipment, and laboratory analyzers.

Key design considerations: Insulation coordination per IEC 60664, overvoltage category assignment, working voltage analysis, creepage and clearance per pollution degree, abnormal and fault condition analysis.

IEC 60335

Household and Similar Electrical Appliances

IEC 60335 is the safety standard for household appliances and a broad range of commercial and industrial electrically powered equipment. Its scope covers appliances from simple resistive heaters to complex motor-driven machines. We have designed products to multiple parts of the IEC 60335 series, addressing abnormal operation requirements, thermal cutouts, motor protections, and appliance-specific clauses.

Key design considerations: Thermal protector selection and placement, motor protection, supply cord strain relief, enclosure requirements, abnormal operation test preparation.

IEC/UL 60730

Automatic Electrical Controls

IEC 60730 and its UL equivalent govern automatic electrical controls used in household and similar appliances — thermostats, pressure switches, motor protectors, and programmable controllers that are safety-relevant components within a larger appliance. We design control systems to the requirements of this standard, including fault analysis, software class requirements, and independently-assessed component selection.

Key design considerations: Software class assignment (A, B, or C), fault analysis, independently assessed component selection, micro-disconnection requirements.

IEC 60079

Equipment for Explosive Atmospheres (Ex/ATEX/IECEx)

Designing for explosive atmospheres is among the most demanding disciplines in electronics safety. IEC 60079 defines the requirements for equipment used in zones where flammable gases, vapors, dust, or fibers may be present. Protection concepts such as intrinsic safety (Ex i), flameproof enclosure (Ex d), increased safety (Ex e), and pressurized enclosure (Ex p) each carry specific design, materials, and documentation requirements.

Key design considerations: Protection concept selection, entity parameters (Ex i), spark ignition risk analysis, enclosure materials and ingress protection, Ex-certified component selection.

UL Standards

North American Market

For products entering the United States and Canadian markets, UL certification under applicable product safety standards is typically required or strongly expected. We design with UL requirements in mind, leveraging the harmonization between IEC and UL standards where available, and managing the differences where they are not.

Key design considerations: UL/IEC harmonization gaps, UL Listed vs. Recognized component requirements, North American creepage/clearance tables, CSA requirements for Canadian market.

CCC

China Compulsory Certification

Products sold in China that fall under regulated product categories require CCC certification. We support product development with CCC requirements in mind, from component selection to documentation preparation, and coordinate with accredited Chinese certification bodies when required.

Key design considerations: GB standard requirements, CCC-required component certification, Chinese test laboratory coordination, documentation in Chinese regulatory format.
