Standard Name: Electrical properties of fresh and used oils from electric drives in vehicles – Measurement of the specific electrical conductivity, the relative permittivity (εr) and the dielectric dissipation factor (tan δ)
Standard Number: DIN 51111:2024-02
Scope: This standard specifies the methods for measuring the electrical properties, including specific electrical conductivity, relative permittivity (εr), and dielectric dissipation factor (tan δ), of fresh and used oils in electric drives of vehicles. It applies to oils used in electric propulsion systems and provides guidelines for the measurement equipment, procedures, and conditions to ensure accurate and consistent results.
The standard is divided into sections covering the scope, normative references, terms, brief description, and equipment required for the measurements. It includes detailed specifications for the measuring apparatus, temperature control units, and measuring cells, ensuring that the measurements are performed under controlled and standardized conditions.
