RoHS Breakdown: Concept → Limit Requirements → Scope of Application → Testing Process → Compliance Key Points.
I.
What is RoHS and what are the limit requirements?
What is RoHS: RoHS stands for the EU’s “Restriction of Hazardous Substances” directive—limiting the content of hazardous substances in electrical and electronic products (industry consensus); the current version is RoHS 2.0 (2011/65/EU)—mandatory compliance for electrical and electronic products entering the EU market. Limit requirements (6 original categories + 4 added items): 1. Lead (Pb) ≤ 1000 ppm; 2. Mercury (Hg) ≤ 1000 ppm;
3. Cadmium (Cd) ≤ 100 ppm; 4. Hexavalent Chromium (Cr6+) ≤ 1000 ppm; 5. Polybrominated Biphenyls (PBB) ≤ 1000 ppm; 6. Polybrominated Diphenyl Ethers (PBDE) ≤ 1000 ppm; RoHS 2.0 added 4 phthalates (DEHP/BBP/DBP/DIBP—each ≤ 1000 ppm)—limit unit: ppm (parts per million); exceeding the limit constitutes non-compliance.
II. Scope of Application and Testing Process
Scope of application (which products require it): 1. Electrical and electronic equipment (home appliances/IT/lighting/tools);
2. Industrial consumables containing electronic components (consumables with sensors/controllers); 3. Wires, cables, connectors, and power supply products; 4. Electronic packaging materials—purely mechanical parts (without electronic components) generally do not apply—consumables with electronic parts require RoHS compliance, while purely mechanical parts do not.
Testing and Certification Process: 1. Confirm applicability (check for electronic components); 2. Submit samples for testing (third-party laboratory—per IEC 62321 standards); 3. Obtain test report (retain compliant reports on file); 4. Address customer requirements (EU clients often require RoHS reports or Declarations of Conformity); 5. Ongoing control (re-testing upon material changes)—Confirm → Submit → Report → Declare → Control.
III.
Compliance Essentials and Pitfalls to Avoid
Compliance Essentials: 1. Material control (supplier RoHS compliance—ensure compliance at the source); 2. Change management (re-test if materials or processes change); 3. Document management (archive test reports/declarations—ready for customer audits).
Four Pitfalls to Avoid: 1. Exceeding limits (excessive lead/cadmium—entire batch fails); 2. Expired reports (manage report validity periods); 3. Non-compliant supplier materials (failure to check at the source—finished product fails); 4. Overlooking new requirements (e.g., the four phthalates in RoHS 2.0—older reports may not cover them)—Compliance starts at the source.
IV.
Testing Costs, Timelines, and Document Management
Cost and Timeline Reference (Industry Norms): RoHS testing is charged by material type (metals, plastics, and coatings tested separately)—costs range from several hundred to over a thousand yuan per material, or several thousand for a complete product (depending on the number of components); Timelines—standard 3–7 working days, expedited 1–2 days (surcharge applies)—quotes are based on component count; clarify details before submission.
Document Management: Test reports (archive originals/scans), Declaration of Conformity (DoC), supplier material declarations (upstream RoHS data), and tracking logs (report validity/re-test reminders)—keep a complete set of documents to ensure readiness for customer audits.
V. Summary: RoHS is the EU Market Entry Threshold; Compliance Starts at the Source
Key Takeaways: What are the RoHS certification requirements for industrial consumables? Limits (Pb/Hg: 1000 ppm; Cd: 100 ppm; Cr(VI): 1000 ppm; PBB/PBDE: 1000 ppm; plus four phthalates added under RoHS 2.0 at 1000 ppm each); Scope (compliance required for consumables containing electronic components; not required for purely mechanical parts); Process (Verification → Testing → Report → Declaration → Control); Costs (starting from a few hundred for single materials to a few thousand for a full set—industry standard estimates).
In a nutshell: RoHS requirements—remember the limits (Pb/Hg: 1000; Cd: 100; Cr: 1000; PBB/PBDE: 1000; 4 phthalates: 1000); compliance is mandatory for items with electronic components (third-party testing per IEC 62321) but not for purely mechanical parts; ensure compliance at the material source, re-test upon changes, and archive reports; avoid pitfalls—exceeding limits, expired reports, non-compliance at the source, or overlooking the new phthalate requirements. RoHS is the EU market entry threshold;
compliance starts at the source.
