Objective:
Regulated Substances: ROHS restricts the use of the following substances:
These substances are limited to 0.1% by weight in homogeneous materials, except for cadmium, which is limited to 0.01%.
Product Categories: ROHS applies to a wide range of EEE, including:
Exemptions: Certain applications are exempt if no feasible alternative exists, particularly in medical devices and monitoring/control instruments. Exemptions are reviewed periodically to determine if alternatives have become feasible.
Compliance Requirements:
Product Compliance Statement: Provide a statement confirming that the product complies with the ROHS directive requirements. This statement should include details such as the product name, model number, and declaration of conformity.
List of Restricted Substances: Disclose the substances restricted under the ROHS directive that are present (or intentionally added) in the product. The substances typically restricted include lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr VI), polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE).
Materials Declaration: Provide a detailed materials declaration listing the substances and their concentrations in the product. This declaration may require information from suppliers and testing to ensure accuracy.
Testing and Certification: Include details of any testing conducted to verify compliance with ROHS requirements. Provide certificates or test reports from accredited laboratories demonstrating compliance.
Compliance with Other Regulations: If the product is subject to additional regulations or directives related to hazardous substances (e.g., REACH regulations in the EU), disclose compliance with those regulations as well.
Manufacturer Information: Provide information about the manufacturer or importer responsible for placing the product on the market. This includes contact details and identification numbers as required by regulatory authorities.
Materials Declaration: This document lists all the materials used in the product, including their compositions and concentrations. It specifically highlights whether any of the restricted substances (lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers) are present above the allowed thresholds.
Certificate of Conformity: A certificate issued by the manufacturer or importer declaring that the product complies with the ROHS directive. This certificate should include details such as product identification (model number, serial number), compliance statement, and signature of an authorized person.
Test Reports: Reports from accredited laboratories detailing the results of tests conducted on the product to verify compliance with ROHS requirements. These reports should include information on testing methods used, limits of detection, and results for each restricted substance.
Supplier Declarations: Declarations from component suppliers confirming that the materials and components they provide comply with ROHS requirements. These declarations may be required to support the overall compliance of the finished product.
Technical Files: Comprehensive technical documentation that supports the manufacturer's declaration of conformity. This may include design drawings, bills of materials (BOMs), assembly instructions, and other relevant technical specifications.
Traceability Records: Records that demonstrate traceability of materials and components used in the manufacturing process. This helps ensure that the materials used in the product comply with ROHS requirements throughout the supply chain.
Labeling and Marking Information: Information related to labeling and marking of the product to indicate compliance with ROHS requirements. This includes placement of compliance marks and other required information on the product packaging or documentation.
Recyclability Information: Information on the recyclability of the product and guidance for proper disposal in accordance with environmental regulations.
