What these attestations mean. TÜV SÜD issues them on a voluntary basis. They confirm that the tested samples meet the principal protection requirements of the directives, and they apply only to the samples submitted. They do not replace the EU Declaration of Conformity (DoC) and do not on their own allow CE marking; the manufacturer applies CE marking after preparing the technical documentation and signing a DoC. The attestations list a protection degree of IP00 because the units are designed to be installed inside a cabinet, and the end product must also meet its own standard.
How to Verify Our Certificates
- ISO certificates: search the certificate number on the China National Certification and Accreditation Administration website (www.cnca.gov.cn) or the CFC website (www.bjsxlh.com), or scan the QR code on the certificate.
- TÜV SÜD attestations: TÜV SÜD refers to www.tuvsud.com/ps-cert for details. We can also share the full test reports on request.
- Company identity: our Unified Social Credit Code is 91430211666343296C, which appears on all three ISO certificates.
Frequently Asked Questions
Are Gongchuang dehumidifiers CE marked?
The TÜV SÜD attestations confirm that the tested GCH and JY samples meet the principal protection requirements of the Low Voltage and EMC directives. A TÜV SÜD attestation does not itself allow CE marking; the manufacturer applies CE marking after preparing the technical documentation and signing an EU Declaration of Conformity. Ask us for the current DoC status of the model you need.
Which dehumidifier models are TÜV SÜD tested?
GCH-8120S, GCH-8120TS, GCH-8120T and GCH120W are tested under both the Low Voltage and EMC directives. JY-760A, JY-760A(CE) and JY-760A(60W) are tested under the Low Voltage Directive.
Why do the TÜV SÜD attestations list IP00?
The dehumidifiers are designed to be installed inside a cabinet or enclosure, which provides the ingress protection. The attestations note that the requirements of the end product standard must also be met once the unit is installed.
How can I verify Gongchuang's ISO certificates?
Search the certificate numbers on the China National Certification and Accreditation Administration website (www.cnca.gov.cn) or the Beijing Credit First Certification website (www.bjsxlh.com), or scan the QR code on each certificate.
