FAQ

What is US TSCA Testing?

TSCA testing, full name Toxic Substances Control Act testing, is a regulatory requirement implemented by the U.S. Environmental Protection Agency (EPA). It aims to ensure that products sold in the U.S. market do not contain chemical substances that pose unreasonable risks to human health or the environment. TSCA testing typically covers various hazardous substances, including but not limited to decabromodiphenyl ether, isopropylated triphenyl phosphate, hexachlorobutadiene, 2,4,6-tri-tert-butylphenol, and pentachlorothiophenol. The content of these substances in specific products is strictly restricted to ensure product safety.

How Much Sample is Required for TSCA Testing?

Generally, 0.5 to 1 gram of sample is needed for each test. However, considering the needs for retesting and sample 留样 (sample retention), the recommended quantity of submitted samples is usually 5 to 10 grams. This sample amount ensures the smooth progress of the testing process and avoids testing delays or failures due to insufficient samples.

Relevant enterprises should closely monitor updates to U.S. regulations, reasonably arrange product testing to ensure compliance, and timely conduct regulatory standard consultations or training to improve product quality. Tailored testing solutions can be provided to help enterprises understand the presence of 5 PBT substances in their products, effectively respond to regulatory updates.

In modern electronic product manufacturing, RoHS (Restriction of Hazardous Substances) testing is becoming increasingly important, especially for companies planning to enter the EU market. RoHS testing is not only about environmental compliance but also directly impacts a company's market competitiveness and brand image. Today, the Huabiao Testing team will share with you: What are the 10 substances restricted under RoHS? How to handle RoHS testing for water purifier filter casings?

What are the 10 substances restricted under RoHS?

The RoHS Directive (Directive 2011/65/EU and its amendment 2015/863) is a regulation established by the EU in 2002 and implemented in 2006. It aims to restrict the use of specific hazardous substances in electrical and electronic equipment to protect human health and the environment. RoHS applies to a wide range of products, including household appliances, consumer electronics, industrial equipment, medical devices, and more. If a water purifier filter casing contains electrical or electronic components (such as control circuits or displays), it must also comply with RoHS requirements.

The 10 substances restricted under RoHS:

With the frequent issuance of targeted global regulations in recent years, the focus on PFAS (Per- and Polyfluoroalkyl Substances) control has reached new heights. However, today, Huabiao Testing shares insights on the testing items for PAHs (Polycyclic Aromatic Hydrocarbons) in scooters and the process for obtaining PAHs certification.

Scooter PAHs Testing Items

PAHs testing for scooters primarily assesses whether materials in the scooter contain excessive levels of polycyclic aromatic hydrocarbons. Testing items include, but are not limited to, components such as plastic handles, plastic packaging boxes, and rubber grips that may contain PAHs. The testing scope varies based on requirements from the German GS certification and EU REACH Annex XVII. GS certification typically tests for 15 PAHs, while REACH Annex XVII tests for 8 PAHs. Therefore, it is essential to clarify the specific testing requirements before proceeding to ensure accurate results.

Scooter PAHs Testing Certification Process

1. Sample Preparation
   Clients must provide samples for testing. Liquid samples should be no less than 20 milliliters, and solid samples should be no less than 50 grams. Additionally, clients must submit a Bill of Materials (BOM) or product images to confirm the materials used.

2. Quotation Confirmation
   The testing agency will prepare a detailed quotation based on the provided information and testing requirements. Clients must review and confirm the quotation, affix their company seal, and make the required payment for testing fees.

3. Sample Testing
   Upon receiving the samples, the testing agency will conduct rigorous testing in accordance with relevant standards. The standard testing cycle typically takes 5 to 7 working days. If clients require expedited services, additional fees may apply based on the specific circumstances.

4. Report Issuance
   Upon completion of testing, the agency will provide a comprehensive test report. If the results are compliant, an electronic version of the report will be issued. If the results indicate non-compliance, the report will specify the items exceeding limits, and the client will be notified to make necessary rectifications. After rectification, clients may request a free retest. Upon passing the retest, the final report will be formally issued.
