What does the REACH SVHC test result mean for the Helios J1?

All 250 SVHC substances and 2 additional potential substances from the ECHA Candidate List were Not Detected (ND) in every material group of the Helios J1. Each homogeneous material contains less than 0.1% w/w of any SVHC, satisfying REACH Article 59 disclosure and notification obligations under EC Regulation 1907/2006.

Which test laboratory conducted the SVHC analysis?

Testing was performed by Waltek Testing Group (Shenzhen) Co., Ltd., an accredited third-party laboratory in Shenzhen, China. The report number is WTH25X06164717C, issued 2025-07-29 and signed by Hugo Chen.

How many material samples were tested across the Helios J1?

Over 107 individual material samples were tested, organised into nine groups (T01–T09) covering metals, nonmetals, electronic components, PCB assemblies, rubber parts, adhesives, wire insulation, and connectors. All groups returned a Not Detected result.

Does this report remain valid if the ECHA Candidate List is updated?

The report reflects compliance against the ECHA Candidate List as of the 2025 testing date. Since ECHA periodically adds new substances, it is recommended to re-screen the Helios J1 against newly added substances after each ECHA Candidate List update.

This means every homogeneous material in the product contains less than 0.1% w/w of any SVHC, satisfying the disclosure and notification obligations under EC Regulation 1907/2006 (REACH).
Which test laboratory conducted the SVHC analysis?: The testing was conducted by Waltek Testing Group (Shenzhen) Co., Ltd., an accredited third-party laboratory based in Shenzhen, China. The report number is WTH25X06164717C, issued on 2025-07-29 and signed by Hugo Chen.
How many material samples were tested across the Helios J1?: The product was disassembled into over 107 individual material samples, grouped into nine test groups (T01–T09), covering metals, nonmetals, electronic components, PCB assemblies, rubber parts, adhesives, wire insulation materials, and connectors. Every group returned a Not Detected result.
Does this report remain valid if the ECHA Candidate List is updated?: This report reflects compliance against the ECHA Candidate List as of the testing date in 2025. Because ECHA periodically adds new substances to the Candidate List, it is recommended to re-screen the Helios J1 against any newly added substances following each ECHA update to confirm ongoing compliance.
