What is BS EN 60819-3-3 - Material for non-cellulosic papers about?
BS EN 60819-3-3 deals with non-cellulosic papers for electrical purposes. BS EN 60819-3-3 specifies requirements for four types of unfilled aramid papers:
- Type 1: Calendered paper
- Type 2: Calendered paper, with improved tearing resistance and conformability
- Type 3: Uncalendered paper
- Type 4: Calendered paper, with lower density for laminating
Materials which conform to specification provided in BS EN 60819-3-3 meet established levels of performance. However, the selection of material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.
Who is BS EN 60819-3-3- Material for non-cellulosic papers for?
BS EN 60819-3-3 on material for non-cellulosic papers is useful for:
- Electrical engineer
- Manufacturer of heavy electrical equipment
- Manufacturer of electrical appliances
- Power Distribution companies
- Electrical cable manufacturers
- Insulator manufacturers
Why should you use BS EN 60819-3-3 - Material for non-cellulosic papers?
Non-cellulosic paper is used as an insulator in electrical appliances. Making sure the manufacture and production of such insulating materials is according to the industry standards is important for safety and reliability of products.
BS EN 60819-3-3 provides requirements of unifilled aramide for non cellulosic papers:
- Thickness
- Grammage
- Apparent density
- Minimum elongation at break
- Minimum edge tearing resistance
- Minimum tensile strength
- Minimum electric strength
- Maximum shrinkage on heating
BS EN 60819-3-3 helps both supplier and manufacturers using non-cellulosic papers in selecting material for the suitable application. High quality insulators further reassure the reliability of the electrical equipment.
What’s changed since the last update?
BS EN 60819-3-3:2011 supersedes EN 60819-3-3:2006.
EN 60819-3-3:2011 includes the following significant technical changes with respect to EN 60819-3-3:2006:
- Normative references change: all the requirements are now determined according to the clauses of test methods from EN 60819-2 specific for non-cellulosic papers, instead of EN 60554-2:2002 generally valid for cellulosic papers
- Some new, very thin thicknesses, of type 4, calendered paper with lower density for laminating, were added
