TUV Rheinland Certified

TUV Rheinland Certified

In early 2014, Astron Australia applied for the globally recognised TUV Rheinland conformance certificate to be applied onto its AS4702 polymeric cable cover. We undertook this to differentiate our product in the market and reassure our clients that our cable cover is second to none when it comes to quality. Please download the TUV Rheinland brochure to understand further the benefits of purchasing Astron’s cable cover.
