ASTM D149 Dielectric Breakdown Voltage Testing: Laboratory Testing Services

Standard-Related Information

ASTM D149 Dielectric Breakdown Voltage Testing is a critical laboratory testing service that evaluates the dielectric strength of electrical insulating materials. This test is governed by various international and national standards, including ASTM (American Society for Testing and Materials), ISO (International Organization for Standardization), EN (European Norms), TSE (Turkish Standards Institution), and others.

ASTM D149

The primary standard governing this testing service is ASTM D149-18, Standard Test Method for Dielectric Breakdown Voltage of Solid Electrical Insulating Materials at Commercial Power Frequencies. This standard outlines the procedures for conducting dielectric breakdown voltage tests on solid electrical insulating materials, such as plastics, ceramics, and glass.

ISO 60093-1

Another relevant standard is ISO 60093-1:2018, Insulators for overhead lines with a nominal voltage greater than 1000 V (a.c.) - Part 1: Ceramic pin-type insulators. This standard specifies the requirements for ceramic pin-type insulators used in overhead power transmission and distribution lines.

EN 60090-1

The European Standard EN 60090-1:2018, Electrical Insulation Systems (EIS) for Low Voltage Switchgear and Controlgear Units - Part 1: Definitions, Service Conditions and General Requirements, also applies to this testing service. This standard outlines the requirements for electrical insulation systems used in low-voltage switchgear and controlgear units.

TSE EN
