Approved heating elements: safety testing and quality certificates

The whole range of our heating elements complies with EN 60335.1 standards, as well as with the essential requisites for Low Voltage Directives and the actual legislation concerning electrical material safety.

On Customers’ request, heating elements are UL-CSA or VDE approved, or in any case they have other product marks consistent with customer’s specific requests. Special products that are used in explosive areas can be approved according to explosion-proof specifications by CESI. Flexible heaters in polyamide for the space-military applications are ESA approved, since 1992. This homologation, re-qualified every 2 years to comply with the existing standards, is recorded in the ESA-EPPL with the approval certificate No. 184E.

The product approvals are carried out in the laboratories of each division by the Quality staff in co-operation with the engineers of the Certification Authority.The laboratories where tests are made are qualified in accordance with the applicable standards and normative.

For the execution of chemical analysis, tests on raw materials (steel, oxide), corrosion and mechanical tests, and for electromagnetic compatibility tests according to current standards, ZI Heating Elements Technologies is supported by external Agencies.

All the production is 100% tested and, on customer request, additional tests can be effected by the Quality Control Department, with relative issue of quality and conformity Certificate. In order to promote the partnership with the customers, products are developed in co-design with the customer and during the sampling phase, tests are carried out not only on the component but also on the final equipment-component assembly.
