BS EN 61212-1:1996 is a British Standard that has been adopted as a European Standard (EN). It is titled "Insulating materials - Industrial rigid laminated sheets based on thermosetting resins for electrical purposes - Part 1: Definitions, designations, and general requirements."
This standard specifies the general requirements and test methods for industrial rigid laminated sheets used as electrical insulation in various applications. These laminated sheets are made from thermosetting resins, such as phenolic or epoxy resins, reinforced with materials like cellulose paper, fabric, or glass cloth.
The standard provides definitions and designations for different types of laminated sheets, including their thicknesses, classes, and grades. It also outlines the general requirements for their mechanical, electrical, and thermal properties, as well as dimensional tolerances and surface finish.
BS EN 61212-1:1996 covers the following aspects:
Definitions and designations: It establishes terminology and codes used to identify different types of laminated sheets.
General requirements: It specifies the mechanical, electrical, and thermal properties that the laminated sheets should possess, including flexural strength, electrical strength, thermal endurance, and resistance to chemicals.
Test methods: It describes the test procedures for evaluating the properties of the laminated sheets, such as determination of thickness, density, electrical strength, and thermal endurance.
Dimensions and tolerances: It provides guidelines for the dimensions, thickness tolerances, and flatness requirements of the laminated sheets.
Surface finish: It defines the surface finishes of the laminated sheets and their corresponding designations.
It's important to note that standards can be updated or revised over time. The information provided here is based on the version of the standard as of 1996. It's recommended to consult the latest version or any relevant amendments or revisions for the most up-to-date information.
