Keywords: industrial rigid laminated sheets based on thermosetting resins.

Deals with combined flexible insulating materials consisting of two or more different insulating materials laminated together. The components taken into consideration are plastic films and/or fibrous materials such as papers, woven or non-woven fabrics, impregnated or not impregnated.

IEC 60819-1:2009 gives the definitions and general requirements for non-cellulosic papers for electrical purposes. The main changes from the previous edition are as follows: the list of materials to be used in combination was updated with the addition of new materials made available by progress in technology and described in Subclauses 2.7 and 2.8.

Gives the requirements for industrial rigid laminated sheets for electrical purposes based on melamine resins and different reinforcements. Applications and distinguishing properties are given. Materials which conform to this specification meet established levels of performance. However, the selection of a 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. In this revision of the IEC 60893 series of specifications, new material types have been included, changes have been made to the property requirements of some existing types, a new method for testing permittivity and dissipation factor has been added, and all non-specification data for each type has been moved to a new Part 4 document - IEC 60893-4 - Typical values.

IEC 60819-3-3:2011 is a sheet of IEC 60819-3 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. This edition includes the following significant technical changes with respect to the previous edition: - normative references change: all the requirements are now determined according the clauses of test methods from IEC 60819-2 specific for non cellulosic papers, instead of IEC 60554-2:2001 generally valid for cellulosic papers; - and some new, very thin thicknesses, of type 4, calendered paper with lower density for laminating, were added.

IEC 60684-2:2011 gives methods of test for flexible insulating sleeving, including heat-shrinkable sleeving, intended primarily for insulating electrical conductors and connections of electrical apparatus, although they may be used for other purposes. The tests specified are designed to control the quality of the sleeving but it is recognized that they do not completely establish the suitability of sleeving for impregnation or encapsulation processes or for other specialized applications. Where necessary, the test methods in this part will need to be supplemented by appropriate impregnation or compatibility tests to suit the individual circumstances. The main changes from the previous edition are as follows: three additional methods for circumferential extension, voltage proof and thermal shock and alignment with North American methods.

IEC 60674-3-8:2011 gives the requirements for balanced biaxially oriented polyethylene naphthalate (PEN) films for use as electrical insulation.

IEC 60684-3-271:2011 gives the requirements for four types of heat-shrinkable, flame retarded, fluid resistant, elastomer sleevings, nominal shrink ratio of 2:1. - Type A: standard wall thickness for use at temperatures up to 120 °C - Type B: thin wall thickness for use at temperatures up to 120 °C - Type C: standard wall thickness for use at temperatures up to 150 °C - Type D: thin wall thickness for use at temperatures up to 150 °C. The significant technical change from the previous edition is the addition of a type of sleeving suitable for use at temperatures up to 150 °C. This edition includes the following significant technical change from the previous edition: the addition of a type of sleeving suitable for use at temperatures up to 150 °C.

IEC 60684-3-205:2011 gives the requirements for one type of heat-shrinkable chlorinated polyolefin sleeving, flame retarded, nominal shrink ratio 1,7:1 and 2:1 for use at temperatures up to 120 °C.

Gives the requirements for industrial rigid laminated sheets for electrical purposes based on epoxy resins and different reinforcements. Applications and distinguishing properties are given. Materials which conform to this specification meet established levels of performance. However, the selection of a 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. In this revision of the IEC 60893 series of specifications, new material types have been included, changes have been made to the property requirements of some existing types, a new method for testing permittivity and dissipation factor has been added, and all non-specification data for each type has been moved to a new Part 4 document - IEC 60893-4 - Typical values.

IEC 60763-1:2010 contains the definitions required for the understanding of all three parts of IEC 60763, the classification of material into types, and the general requirements applicable to all material covered by the standard. The main changes with respect to the previous edition is that the specification was brought in line with the second edition of IEC 60641-1(2007).

IEC 60763-3-1:2010 gives the requirements for laminated precompressed boards comprised of 100 % sulphate wood pulp. The main changes with respect to the previous edition are: - requirements for the new properties in Part 2 have been integrated; - specifications for type LB3.3.1 and LB3.3.2 have been deleted.

IEC 60684-3-282:2010 gives the requirements for two types of heat-shrinkable, polyolefin sleeving, stress control, not flame retarded, with a nominal shrink ratio up to 3:1. This sleeving has been found suitable for use up to temperatures of 100 °C. - Type A: Medium wall - Internal diameter up to 65,0 mm typically - Type B: Thick wall - Internal diameter up to 95,0 mm typically
