IEC 60730 Class B and C Safety Standards
IEC 60335 is the safety standard for household appliances and similar appliances with automatic electrical controls. IEC 60335 refers to the IEC 60730 standard for electronic controls of such appliances and IEC 60730 is currently mandatory for home appliances sold in Europe and other places around the world.
Annex H in IEC 60730-1 defines the safety requirements for electronic controls and Table H.1 (H.11.12.7 in edition 3) defines the acceptable measures to address faults and errors. This standard covers the safety levels referred to as Class B, which includes thermal cut-out functions, and Class C, which covers functions with higher risk of failure, such as automatic gas burner controls.
IEC/UL 60730-Certified Touchscreen Controllers
Our maXTouch® touchscreen controller family contains five products that implement unique safety-related features such as self-tests and touch sensor tests. These products are certified by VDE and UL for full IEC/UL 60730 class B compliance.
Supporting Collateral for Functional Safety-Ready MCUs and DSCs
IEC 60730 Functional Safety Ready MCUs and DSCs encompass the latest hardware safety features and a comprehensive safety ecosystem to simplify the design and certification of safety-critical household applications. We offer:
- Specialized hardware safety features to achieve safety goals
- Certified IEC 60730 Class B library
- Functional safety-qualified MPLAB® development ecosystem
- TÜV SÜD-certified MPLAB XC compilers with qualification packages
IEC 60730 Diagnostic Test Libraries
Whether you are new to IEC 60730 functional safety or a seasoned expert, you can trust our proven experience and solutions to help you meet functional safety requirements while minimizing cost, risk and development time.
The IEC 60730 Class B library is a software library that contains all the diagnostic tests demanded by the IEC 60730 standard to submit your end product for Class B certification. The library is certified by UL and verified by VDE. We distribute it as a stand-alone software package for dsPIC33E DSCs, PIC24F and SAM MCUs or as an MPLAB Code Configurator (MCC) package for PIC® and AVR® MCUs. The library is free to use with our MCUs and DSCs. We recommend using the library with one of the safety-certified MPLAB XC PRO functional safety compilers.
PIC16, PIC18 and AVR MCUs
These low-power MCUs are affordable and popular as main controllers for capacitive touch interfaces, as main controllers in smaller designs and as safety co-processors in larger designs.
PIC24 MCUs
Our low-power PIC24F MCUs can function as the main controller for sensor interfacing and control, low-power designs, applications requiring segmented LCD display and USB connectivity in household appliances.
dsPIC33E DSCs
Our high-performance dsPIC33E DSCs can be used as the main controller to implement advanced control and sensor interfacing, motor control, digital power, touch, connectivity and high-performance general embedded designs in your household appliances.
SAM and PIC32 MCUs
These MCUs contain powerful, industry-standard Arm® cores, making them ideal for home appliances with capacitive touch interfaces and motor control.
When you are designing functional safety applications, using development tools that meet the requirements of safety standards can make it easier for you to create compliant systems. Our MPLAB XC C compilers are TÜV SÜD-certified for several functional safety standards and can help you comply to system-level functional safety requirements for your applications. Our complete certification packages for our MPLAB development tools ecosystem are essential to qualify the software tools required in your embedded projects.
MPLAB X IDE
Organize, write, test and debug your embedded software applications in the MPLAB X IDE.
MPLAB XC Compiler
Build your embedded software with the TÜV SÜD-certified MPLAB XC8 Pro Functional Safety Compiler.
MPLAB Analysis Tool Suite
MPLAB Analysis Tool Suite offers a code coverage feature and a Motor Industry Software Reliability Association (MISRA®) check in the IDE.
Achieving Class C Safety Level
For appliances where failures are associated with high risk, such as automated gas burner control applications, the IEC 60730 Class C safety level is likely to apply. The public and free Class B library does not cover all the diagnostic tests required for Class C safety levels. If your application requires Class C conformance, please reach out to one of our local sales offices for additional information or get in touch with our Client Success Team who can assist you with sales, product inquiries and support for new designs.
