What is BS EN IEC 62631-2-1-Dielectric and resistive properties of solid insulating materials about?
BS EN IEC 62631 is an international standard that discusses the dielectric and resistive properties of solid insulating materials.
BS EN IEC 62631-2-1 is one of the parts in the multi-series standard that describes test methods for the determination of permittivity and dissipation factor properties of solid insulating materials (AC methods from 0,1 Hz up to 10 MHz).
NOTE: This part of the standard mainly considers measuring setups with guard-electrodes
Who is BS EN IEC 62631-2-1-Dielectric and resistive properties of solid insulating materials for?
BS EN IEC 62631-2-1 on dielectric and resistive properties is relevant to:
- Manufacturers of insulating materials
- Manufacturers of electrical applications
- Quality testing personnel
- Product design engineers
- Electrical engineers
Why should you use BS EN IEC 62631-2-1-Dielectric and resistive properties of solid insulating materials?
Tan δ, also called loss tangent, or dissipation factor is a basic parameter for the quality of insulating materials. The measurement of capacitance and loss angle is a classical method well established in the industry over 100 years. The dissipation factor (tan δ) is dependent on several parameters, such as electrode design, material characteristics, environmental issues, moisture, temperature, voltage applied, and highly dependent on frequencies, the accuracy of measuring apparatus and other parameters applied to the measured specimen. The frequency range is limited, depending on the test cell and electrode design, the dimension of the samples and connection leads. In BS EN IEC 62631-2-1 the parameters for the frequencies applied are therefore limited in the range of very low frequency (VLF) from less than 1 Hz and up to 10 MHz. However, measuring instruments can provide a broader frequency range, whereby the usable and suitable frequency range is limited by the whole test setup.
Compliance with BS EN IEC 62631-2-1 can assist you in selecting insulating materials that contribute to higher efficiency, durability, and performance of the end-use application.
What’s changed since the last update?
BS EN IEC 62631-2-1 replaces the first edition IEC 60250, published in 1969. This edition includes the following significant technical changes with respect to the previous edition:
- Technical frequencies confined to AC methods
- Update on measurements on solid dielectric materials
