Within its programme of work, Technical Committee CEN/TC 306 requested CEN/TC 306/WG 2 “Lead alloys” to prepare the following standard :

EN 12548, Lead and lead alloys - Lead alloy ingots for electric cable sheathing and for sleeves.

1 Scope

This European Standard specifies the designation, chemical composition, sampling and analysis, marking, labelling and other requirements for lead alloys in ingot form which are used for the manufacture of electric cable sheathing and sleeves

2 Normative references

This European Standard incorporates by dated or undated references, provisions from other publications These normative references are cited at the appropriate places in the text and the publications are listed hereafter For dated references, subsequent amendments to or revisions of any of these publications apply

to this European Standard only when incorporated in it by amendment or revision For undated references the latest edition of the publication referred to applies

EN 12402, Lead and lead alloys - Methods of sampling for analysis.

ISO 11014-1, Safety data sheet for chemical products - Part 1 : Content and order of sections.

NOTE For the chemical analysis, prestandards in preparation by CEN/TC 306/WG 3, see bibliography

3 Terms and definitions

For the purposes of this European Standard, the following definitions apply:

3.1

cast

product of one furnace or crucible melt

NOTE All the ingots from a single cast have the same identifying mark

3.2

ingot

cast product intended for remelting and/or processing

3.3

jumbo

very large ingot, with a mass generally much more than 50 kg

3.4

lead alloy

metallic substance consisting predominantly of lead, with one or more metallic elements intentionally included or retained

Page 5

EN 12548:1999

3.5

bundle

collection of ingots taken from a single cast and secured if necessary, for the purposes of handling, shipment and storage

4 Designation

The material is designated by number (see table 1) This material number designation is in accordance with the system given in annex A (normative)

4.2 Product

The product designation for products to this standard shall consist of :

- denomination (Lead alloy ingot or Lead alloy jumbo) ;

- number of this European Standard (EN 12548) ;

- material number (see 4.1)

The derivation of a product designation is shown in the following example :

EXAMPLE

Lead alloy ingot EN 12548 - PB021K Denomination

Number of this European Standard

Material number

5 Ordering information

In order to facilitate the enquiry, order and confirmation of order procedures between the purchaser and the supplier, the purchaser shall state on his enquiry and order the following information :

a) quantity of product required (mass) ;

b) product designation (see 4.2) ;

c) nominal mass of an ingot (in kilograms) and of a bundle or a jumbo (in tonnes)

In addition, the purchaser shall also state on the enquiry and the order if any of the following is required : d) higher minimum levels for any elements listed in table 1 (see note 1 in table 1) ;

e) maximum limits for any element(s) not listed in table 1 (see note 2 in table 1) ;

f) mark and/or colour coding [see 9.1 d)] ;

g) any special product form (see 6.2) ;

h) certificate of analysis (see 8.2), and/or a declaration of conformity (see 8.3)

EXAMPLE :

Ordering details for 200 t lead alloy ingots, conforming to EN 12548, in material number PB021K, nominal ingot mass 50 kg, nominal mass of a bundle 1 t , with colour coding yellow, with declaration of conformity :

200 t Lead alloy ingot - EN 12548 - PB021K

- nominal ingot mass 50 kg

- nominal bundle mass 1 t

- colour coding yellow

- with declaration of conformity

6 Requirements

The composition of the lead alloys shall conform to the requirements given in table 1

6.2 Shape and size

The shape and size of ingots and jumbos shall be at the discretion of the supplier, unless otherwise agreed between the purchaser and the supplier

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 12402

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 1 When optical emission spectrometry is used, the method should conform to ENV 12908

In case of dispute concerning the results of analysis, the relevant methods of analysis of the prENVs in preparation (see bibliography) to be used to control the compositional conformity of a consignment, apply

NOTE 2 Due to the nature of samples prepared, only chemical analyses are feasible

7.3 Rounding of the results of analysis

The values obtained shall 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 figure 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

a) name and address ;

b) material number ;

c) mass of supplied product ;

d) certificate of analysis (see 8.2)

Other information can also be included, if agreed between the purchaser and the supplier

8.2 Certificate of analysis

The certificate of analysis is a document which certifies the chemical composition of each cast

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 in 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

The 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 material 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 characters shall be as follows :

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

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

A.3.2.2.4 Examples

A.4 Allocation and administration of material numbers

NOTE 1 CEN/TC 306 is responsible for the allocation and administration of material numbers
