Specification of ROHS Testing Service

RoHS (Restriction of Hazardous Substances) testing ensures compliance with EU Directive 2011/65/EU (RoHS 2) and its amendments, which restrict hazardous substances in electrical and electronic equipment (EEE). At Huak Testing, we utilize advanced RoHS testing equipment to identify restricted substances like lead and mercury, helping manufacturers achieve rapid certification for the European market.

Understanding the Process and Requirements of ROHS Testing Service

RoHS Testing Methods

1.X-ray Fluorescence Spectrometry (XRF): XRF is a non-destructive testing method that enables qualitative and quantitative analysis of hazardous substances in products.

3.Gas Chromatography-Mass Spectrometry (GC-MS): GC-MS enables qualitative and quantitative analysis of the six hazardous substances in products.

4.High-Performance Liquid Chromatography (HPLC): HPLC enables qualitative and quantitative analysis of the six hazardous substances in products.

5.Atomic Absorption Spectrometry (AAS): AAS is primarily used for qualitative analysis of the six hazardous substances in products.

6.Pyrolysis-Gas Chromatography (Py-GC): Py-GC is primarily used for qualitative analysis of the six hazardous substances in products.

Ten RoHS Restricted Substances

1.Lead (Pb): The maximum allowable concentration of lead in homogeneous materials is 0.1% (by weight).

2.Mercury (Hg): The maximum allowable concentration in homogeneous materials is 0.1% (by weight).

2.Small Household Appliances: Vacuum cleaners, electric irons, hair dryers, ovens, clocks, etc.

3.IT and Telecommunications Equipment: Computers, fax machines, telephones, mobile phones, etc.

4.Consumer Equipment: Radios, televisions, video recorders, musical instruments, etc.

5.Lighting Equipment: Fluorescent lamps (excluding household lighting), lighting control devices, etc.

6.Electrical and Electronic Tools: Electric drills, lathes, welding equipment, sprayers, etc.

7.Toys, Leisure and Sports Equipment: Electric vehicles, video game consoles, slot machines, etc.

8.Medical Devices: Radiotherapy equipment, ECG testers, analytical instruments, etc.

9.Monitoring and Control Instruments: Smoke detectors, thermostats, industrial monitoring and control equipment, etc.

10.Automatic Dispensers, Semiconductor Devices

Certification Process

1.Product submission: send electrical and electronic products to an accredited third-party laboratory.

2.Testing & analysis: test the content of lead, mercury, cadmium, hexavalent chromium, PBBs, PBDEs and phthalates.

3. Issue results: A draft report will be issued if requirements are met; otherwise, material replacement or design modification shall be required.

4. Issue original document: Upon confirmation of draft information, the final test report and certificate will be provided.

5. Sample return: Samples will be returned upon completion of testing.

Why ROHS Testing Is Essential for Global Market Access

RoHS (Restriction of Hazardous Substances) testing is crucial for ensuring product safety, environmental protection, and regulatory compliance. Here’s why it matters:

1. Health & Safety – RoHS restricts hazardous substances like lead, mercury, and cadmium, which can harm human health if exposed. Compliance reduces risks for consumers and workers.

2. Environmental Protection – By limiting toxic chemicals in electronics, RoHS prevents pollution from e-waste, promoting sustainable disposal and recycling.

3. Legal Compliance– Many countries (e.g., EU, China) mandate RoHS compliance. Non-compliant products face fines, recalls, or market bans.

4. Market Access– RoHS certification is often required to sell products internationally, ensuring global market competitiveness.

5. Corporate Responsibility – Adhering to RoHS reflects a company’s commitment to sustainability and ethical manufacturing, enhancing brand reputation.

Huak Testing can provide customers with ROHS testing and issue report, offering one-stop services from product material selection to shipment customs clearance with reliable ROHS testing equipment.

Q1: What is the RoHS Directive?

A: RoHS (Restriction of Hazardous Substances) is an EU directive that restricts the use of specific hazardous substances in electrical and electronic equipment to protect the environment and human health. The directive specifies ten restricted substances and their maximum allowable concentrations in homogeneous materials.

Q2: What does "homogeneous material" mean?

A: A homogeneous material is a single material that cannot be further mechanically divided, such as a specific type of plastic, metal, or ceramic. RoHS concentration limits apply to each homogeneous material individually, not to the entire.

Q3: What are the characteristics of XRF testing?

A: XRF is a non-destructive testing method that enables qualitative and quantitative analysis of hazardous substances in products. Its advantages include fast testing speed, no need for sample preparation, and no damage to the sample, making it commonly used for rapid on-site screening.

Q4: Are medical devices included in the RoHS scope?

A: Yes, medical devices fall within the scope of the RoHS Directive, such as radiotherapy equipment, ECG testers, and analytical instruments. However, certain medical devices may be exempted due to their specific applications; details should be referred to the official EU exemption list.

Q5: Why is the limit for cadmium stricter than for other substances?

A: Cadmium (Cd) has a maximum allowable concentration of 0.01%, far lower than the 0.1% limit for the other nine substances. This is because cadmium is highly toxic and bioaccumulative, posing severe risks to human kidneys, bones, and the respiratory system, and it does not easily degrade in the environment. Therefore, the EU has imposed stricter restrictions on it.
