Electronics Components ROHS Certification Testing

Electronic components are fundamental parts or devices that perform specific functions within electronic equipment and circuits. They form the basic units of electronic circuits and systems and can be combined in various ways to create complex electronic products. These components vary in type and classification based on their functionality, structure, and application scenarios. Products exported to the EU require CE ROHS certification.

What are electronic components? 

Resistors, capacitors, inductors, diodes, transistors, thyristors, integrated circuits, sensors, relays, switches, transformers, crystal oscillators, batteries, connectors, and power modules.

ROHS Overview 

ROHS stands for "Restriction of Hazardous Substances," an EU-mandated directive that restricts certain hazardous substances in electronic and electrical equipment. The restricted substances include lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs). EU ROHS 2.0 compliance is a fundamental entry requirement for electronic and electrical products in the EU market. JJR Laboratory in China offers one-stop ROHS 2.0 services to facilitate smooth access to the EU market.

EU ROHS Directive 

The ROHS Directive’s full name is "The Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment." ROHS 2.0 applies to electronic and electrical equipment with a maximum operating voltage not exceeding 1000 volts AC or 1500 volts DC that “depends” on electric current or electromagnetic fields for proper functioning, including equipment that generates, transmits, and measures such currents or fields.

1. Scope of Application 

   ROHS 2.0 applies to various electronic and electrical products. The directive covers a wide range of products that require electric current and electromagnetic fields to perform at least one designed function, including:

   - Category 1: Large household appliances 

   - Category 2: Small household appliances 

   - Category 3: IT and telecommunications equipment 

   - Category 4: Consumer equipment 

   - Category 5: Lighting equipment 

   - Category 6: Electrical and electronic tools 

   - Category 7: Toys, leisure, and sports equipment 

   - Category 8: Medical devices 

   - Category 9: Monitoring and control instruments, including industrial monitoring and control instruments 

   - Category 10: Automatic dispensers 

   - Category 11: All other electronic and electrical equipment not covered above 

2. Evaluation Standards 

   The directives in place include 2011/65/EU and its amendment (EU) 2015/863.
