32、en the purchaser and the supplier. 6.3 Surface condition The surface condition of the ingots and jumbos shall be such that it does not affect the composition and is not detrimental to the use of the products 7 Sampling and analysis 7.1 Sampling Sampling shall be carried out in accordance with EN 124
33、02. 7.2 Analysis When analysis is carried out by the supplier to verify conformity of a cast, the analytical methods used shall be at his discretion. NOTE 1When optical emission spectrometry is used, the method should conform to ENV 12908. In case of dispute concerning the results of analysis, the r
34、elevant methods of analysis of the prENVs in preparation (see bibliography) to be used to control the compositional conformity of a consignment, apply. NOTE 2Due to the nature of samples prepared, only chemical analyses are feasible. 7.3 Rounding of the results of analysis The values obtained shall
35、be rounded to the same number of decimal places as used 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 5, the last figure to be retained shall be kept unchanged ; b) if the fig
36、ure immediately after the last figure to be retained is equal to or greater than 5, the last figure to be retained shall be increased by one. Page 7 EN 12548:1999 8 Documentation 8.1 General The supplier shall provide with each consignment the following minimum documentation, including a certificate

Page 9 EN 12548:1999 Annex A (normative) European numbering system for lead and lead alloys A.1 Introduction The numbering system described in this annex is based on annex A to ISO/TR 7003 i
43、n which a unique number is allocated to a lead material (lead or lead alloy) in order to categorize it. A.2 General This annex establishes a numbering system for identifying lead and lead alloys and the responsibility for the allocation and administration of numbers for individual lead materials. Th
44、e system is applicable to lead materials standardized in European Standards prepared by CEN/TC 306. A.3 Details of the system A.3.1 General The number shall be composed of alphabetic (upper case Latin letters) and numeric (Arabic) characters. The system shall provide only one number for each materia
45、l. A number assigned to an individual material shall not be re-assigned to another material even if the first mentioned material has been withdrawn. A.3.2 Structure of numbers A.3.2.1 Complete number The number shall consist of six characters. A.3.2.2 Position of characters The position of character
46、s shall be as follows : 123456 A.3.2.2.1 Positions 1 and 2 The characters for the first two positions shall be the letters “PB“ to designate lead material. A.3.2.2.2 Positions 3 to 5 The characters for the third, fourth and fifth positions shall form a number in the range 001 to 999, see table A.1.
47、Page 10 EN 12548:1999 A.3.2.2.3 Position 6 The character for the 6th position shall be a letter designating one of the material groups given in table A.1.
