EN 61212-1:1995 was produced as a result of international discussions in which the United
8、Kingdom took an active part. BS EN 61212 consists of the following parts: Part 1: General requirements; Part 2: Methods of test; Part 3: Specification for individual materials: Sheet 1 Round laminated rolled tubes; Sheet 2 Round laminated moulded tubes; Sheet 3 Round laminated moulded rods. This Par

24、y, (c) BSI EN 61212-1:1995 BSI 03-19993 Introduction This International Standard is one of a series which deals with industrial rigid round laminated tubes and rods based on thermosetting resins for electrical purposes. This series consists of three parts: Part 1: General requirements (IEC 1212-1);
25、Part 2: Methods of test (IEC 1212-2); Part 3: Specifications for individual materials (IEC 1212-3). 1 General 1.1 Scope This part of IEC 1212 gives the definitions related to, the designations and general requirements to be fulfilled by, industrial rigid round laminated tubes and rods for electrical
26、 purposes made with any of the following resins as the binder: phenolic, epoxide (epoxy), melamine and silicone. The following reinforcements may be used either singly or in combination: cellulosic paper, cotton cloth, glass cloth, mica paper. 1.2 Normative references The following normative documen
27、ts contain provisions which, through reference in this text, constitute provisions of this part of IEC 1212. At the time of publication, the editions indicated were valid. All normative documents are subject to revision, and parties to agreements based on this part of IEC 1212 are encouraged to inve
28、stigate the possibility of applying the most recent editions of the normative documents indicated below. Members of IEC and ISO maintain registers of currently valid International Standards1).

32、ions The tubes and rods covered by this standard are classified into types which differ in the resin and reinforcement employed, the method of manufacture and their distinguishing properties. 3.1 Designation Individual types are designated by: a two-letter abbreviation denoting the resin; a second t
33、wo-letter abbreviation, denoting the reinforcement; a serial number of two digits, the first digit denoting the form of the material: e.g., 2 indicates rolled tubes, 3 indicates moulded tubes and 4 indicates moulded rods, and the second digit distinguishing between sub-grades of the same type; The a
34、bbreviations are given in 3.2. The complete designation of the tube or rod is denoted by: description: rolled tube, moulded tube or moulded rod; number of the IEC standard: IEC 1212 3 Sheet No. ; designation of the individual type; 1) In the event of dispute, the referenced ditions shall be used.

37、led requirements are given in IEC 1212-3. 4 General requirements Appearance Tubes and rods shall be supplied either in the as-produced condition or with a ground finish. In the latter case, their cylindrical surfaces shall be uniform and free from obvious signs of splitting, cracking and delaminatio
38、n. All tubes and rods shall be supplied with their ends smooth and trimmed square. They shall be free from holes, voids or open cracks. NOTE 1Fine stress cracks are an inherent feature of certain types and sizes of tubes and rods, particularly paper base. Such cracks are more likely to occur in rods
39、 of a diameter greater than 25 mm, in tubes of wall thickness greater than 12 mm and in tubes in which the ratio of wall thickness to internal diameter is greater than 0,4. NOTE 2In the case of moulded tubes and rods, some resin concentration is permissible in the region of the mould lines, and at t
40、he centre of rods. NOTE 3Some tubes and rods may be supplied with a varnished or other finish depending upon the agreement between the purchaser and the supplier. 5 Conditions of supply The material shall be supplied in packing which ensures adequate protection during transport, handling and storage
41、. The IEC designation of the material, and the number of pieces or the weight, shall be clearly marked on the outside of each package. Where different types of tubes or rods are contained in the same package, the required information may be on a note accompanying the package. Any marking on an indiv
42、idual tube or rod, and the materials used for marking, shall be as agreed upon in the purchase contract.
