1 Background
|
| TILVA (Testing & Inspection Station for Low Voltage Apparatus ) was established in 1958. TILVA was first recognized as Low –voltage electrical apparatus certifying and testing station by CCEE. In 1991, TILVA became the international accreditation laboratory which can prepare CB test reports independently and the recognized laboratory of TUV. In 1995, TILVA took part in UL data exchange laboratory and climate environment laboratory. In August 2004, our station passed the CB reassessment and scope extension, and became the recognized laboratory of CSA. |
