EN 50307:2002 - 2 - Foreword This European Standard was prepared by the Technical Committee CENELEC TC 20, Electric cables. The text of the draft was submitted to the formal vote and was approved by CENELE
14、C as EN 50307 on 2002-10-01. The following dates were fixed: - latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2003-10-01 - latest date by which the national standards conflicting with the EN have to be with
15、drawn (dow) 2005-10-01 Users of this European Standard should note that it covers the chemical composition of lead and lead alloy cable sheaths or sleeves after application or forming. CEN has issued a European Standard (EN 12548) to cover lead and lead alloy ingots for use in the manufacture of cab
16、le sheaths or sleeves. The compositional requirements therein apply to the material prior to manufacture of the cable sheaths or sleeves and melting loss of some of the alloying elements may occur during processing. Annexes designated “normative“ are part of the body of the standard. Annexes designa
17、ted “informative“ are given for information only. In this standard, Annex A and Annex B are informative. _ - 3 - EN 50307:2002 Contents 1 Scope. 4 2 Normative references. 4 3 Definitions 4 4 Designation 4 5 Ordering information for sheaths and sleeves 4 6 Requirements. 5 7 Sampling 5 8 Analysis meth

EN 12548 Lead and lead alloys - Lead alloy ingots for electric cable sheathing and for sleeves 3 Definitions For the purpose of this standard the following definitions apply. 3.1 electric cable sheath uniform and continuous t
23、ubular metallic covering, generally extruded and generally of a circular cross section, encasing one or more insulated electrical conductors in order to contain an impregnant if present, mechanically protect the insulation, to prevent the ingress of moisture and to act as an electrical screen 3.2 sl
24、eeve short length of sheath which may be used in the jointing of some types of electric cables 4 Designation Lead and lead alloys to this standard are designated by an alphanumeric system, see Table 1. The first letter P signifies lead and lead alloys, the second letter K signifies cables. The three
25、 numbers indicate a specific and unique composition for cable sheaths and sleeves, the third letter S signifies sheath (or sleeve). 5 Ordering information for sheaths and sleeves In order to facilitate the enquiry, order and confirmation of order procedures between the purchaser and supplier for the
26、 supply of lead and lead alloy cable sheaths or sleeves, the purchaser shall state on the enquiry and order the following information: a) the denomination (e.g. sheath or sleeves); b) the number of this European Standard; c) the material designation (see Table 1); - 5 - EN 50307:2002 d) whether chem
27、ical analysis tests are required; e) whether a certificate of analysis tests or a declaration of conformity is required (see Clause 11); f) whether some form of identifier is required for sleeves (see Clause 11); g) in the case of sleeves, the number, length and dimensions. NOTE The tolerances on le
28、ngth, and other dimensions are to be agreed between the purchaser and the supplier at the time of enquiry or ordering. 6 Requirements 6.1 Chemical composition of sheaths and sleeves The chemical composition of the sheaths or sleeves shall conform to the requirements given in Table 1. 6.2 Freedom fro
29、m defects The sheaths and sleeves shall be free of any defects, damage or contamination liable to adversely affect their intended purpose or service life. 7 Sampling Sampling of sheaths or sleeves for chemical analysis shall be in accordance with the requirements of the product specification. 8 Anal
30、ysis methods When analysis is carried out to verify conformity of sheaths and sleeves to this standard the analytical methods used shall be at the discretion of the supplier. In cases of dispute concerning the results of analysis and pending the publication of a suitable European Standard containing
31、 analytical methods (in preparation by CEN), the methods of analysis shall be agreed between the disputing parties. For expression of the results of chemical analysis the rounding rules given in Clause 10 shall be used. 9 Re-test procedure Should any sample fail to meet the specified requirements in
32、 6.1, two further samples shall be taken from the same sheath or batch of sleeves and subjected to the same test or tests in which the original sample failed. Should both additional test samples pass the test, all the cables or sleeves in the batch from which they were taken shall be regarded as com
33、plying with the requirements of this specification. Should either of them fail, the batch from which the samples were representative shall be regarded as failing to comply. Further re-sampling and testing shall be subject to agreement between the supplier and customer. EN 50307:2002 - 6 - 10 Roundin
34、g of analysis results For the purposes of determining conformity to the compositional requirements of this standard, an observed or a calculated value obtained during analysis shall be rounded in accordance with the following procedure. It shall be rounded in one step to the same number of figures u
35、sed to express the specified limit in Table 1. The following rules shall be used for rounding: a) if the figure immediately after the last figure to be retained is less than five, the last figure to be retained shall be kept unchanged; b) if the figure immediately after the last figure to be retaine
36、d is equal to or greater than five, the last figure to be retained shall be increased by one. 11 Inspection documentation for electric cable sheathing and sleeves If requested by the purchaser at the time of ordering, the supplier shall provide inspection documents with each consignment of cables or
37、 sleeves. The documentation shall be as chosen by the purchaser and shall be in accordance with either a) or b) as follows: a) a certificate of analysis, giving the results obtained on the specific batches in the consignment. This certificate shall also include the following information: 1) name and
38、 address of supplier; 2) date of certificate of analysis; 3) name and address of purchaser; 4) purchasers contract, or order, number; 5) a description of the goods and the quantity supplied; 6) details of the specification and alloy designation of the sheathing supplied; 7) signature of suppliers au
39、thorised representative. b) a declaration of conformity of the consignment with the order requirements. This declaration shall include the following information: 1) name and address of supplier; 2) date of declaration of conformity; 3) name and address of purchaser; 4) purchasers contract, or order,
40、 number; 5) a description of the goods and the quantity supplied; 6) details of the specification and alloy designation of the sheathing supplied; and - 7 - EN 50307:2002 7) the following declaration: The goods detailed hereon have been manufactured to conform to the requirements of the purchasers o
41、rder and to the description, quantity and specification detailed thereon.

42、ordance with the requirements of the product standard. 12.2 Sleeves If requested at the time of enquiry or order, the sleeves shall be identified in a manner agreed between the supplier and the purchaser. The identification shall provide the following minimum information: a) the manufacturers name,
43、trade or identification mark; b) the number and year of this European Standard : EN 50307:2002; c) the material designation.
