System certificates held by Zhengzhou ZMS Cable, the CE conformity certificate for the cable range, and the CNAS accreditation of the laboratory that issues our type-test reports.
Every certificate below is shown as a scan, with the registration number, issuing body and the dates printed on the document, so your procurement team can verify it before the tender file is submitted. Product-specific type-test reports are issued with the order.
ISO 9001:2015Quality management system
ISO 14001:2015Environmental management system
ISO 45001:2018Occupational health and safety system
CE / ECMWire and cable type approval
ISO/IEC 17025Testing laboratory accreditation (CNAS L0207)
ISO/IEC 17020Inspection body accreditation (CNAS IB0043)The first four certificates are held by Zhengzhou ZMS Cable Co., Ltd. The last two are CNAS accreditations of the independent laboratory and inspection body that issue our type-test reports, and are shown with the dates printed on those documents. Where a certificate has reached the end of the cycle shown here, the current issue is sent with the tender file — ask our team for the latest copy before you submit.
A management-system certificate covers the plant and its processes. The product certificate covers the construction and the standard. Both are needed in a project file, and they are not interchangeable.

Send the product, the standard and the project country. We will return the certificate, the test report and the declaration of conformity that match the construction.
Request Certificate CopiesPV and storage DC cable is typically specified to IEC 62930 and EN 50618 (H1Z2Z2-K); UL 4703 and UL 854 apply to North American projects. Wind turbine cable follows IEC 60502-1 with torsion testing, and collector cable follows IEC 60502-2. LSZH performance is verified against IEC 60332, IEC 60754 and IEC 61034.
Routine and type tests are carried out on the finished construction. The test report travels with the shipping documents, so the site team can match the reel to the report.
Conductor resistance, cross-section and strand count are checked against IEC 60228 class 5 or class 6 before insulation.
Wall thickness, concentricity, tensile strength and elongation after ageing, hot-set and shrinkage for XLPE, XLPO and LSZH compounds.
Spark test on the insulation, AC or DC voltage withstand on the finished core, and insulation resistance at the specified temperature.
Flame propagation to IEC 60332-1-2, and for LSZH constructions smoke density to IEC 61034 and acid gas to IEC 60754.
Weathering to ISO 4892-2 and UV exposure for PV and tracker cable, followed by mechanical retention checks.
Torsion cycling for wind and tracker cable, low-temperature bend and impact, abrasion and dynamic bend life where the route moves.
