CEN/TC 306 - Lead and lead alloys

This European Standard specifies the designation, the requirements for chemical composition, surface condition and dimensional tolerances for rolled lead sheet. Lead sheet covered by this European standard is made by the roll deformation process and is intended for roofs, flashings, weatherings, claddings, pre-formed panels, damp-proof courses and similar building work.
No requirements for supporting construction, design of roof or cladding systems and methods of joining are included.

This European Standard defines specific terms which are helpful for the communication within the lead industry and its customers relating to scrap of lead and lead alloys.
A clear terminology and classification of these materials, new and used, recovered from products and processes is also contained. No reference is made either to commercial terms of commercial contracts and conditions such as collection, weighing, shipping, receiving and claims or technical values such as lead and alloying elements content, analyticals and physical characteristics such as size and weight. No reference is made to regulatory environmental, health and safety considerations. A glossary (see clause 4) comprises all terms which are defined in this standard and their translations into French and German in alphabetical order.

This European Standard specifies the requirements, acceptance tolerances and chemical and physical test procedures for lead oxides, considering litharges (powder or granulated), battery oxides (Barton or Mill) and crystal red lead. WARNING: Lead and lead compounds are toxic by inhalation and/or ingestion.

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.

This European Standard specifies the designation, chemical composition, sampling and analysis, marking and labelling and other requirements for lead.

This European Standard specifies the methods of sampling of lead and lead alloysfor the purpose of chemical analysis or for the purpose of spectrometric analysis by Optical Emission Spectrometry (OES), with spark excitation.

This European Prestandard specifies methods using flame atomic absorption spectrometry (FAAS) and inductively coupled plasma emission spectrometry (ICP-ES) for the determination of elements at low content in lead for the ranges given in Table 1.
Higher contents than those listed in Table 1 should be determined according to ENV 13800.
These methods are intended as the definitive methods in case of dispute for the determination of elements at low content in lead. They are also recommended for the analysis of Certified Reference Materials (CRM) and Reference Materials (RM) which are used in analysis according to ENV 12908.

This European Prestandard specifies methods using flame atomic absorption spectrometry (FAAS) and inductively coupled plasma emission spectrometry (ICP-ES) for the determination of elements at low content in lead for the ranges given in Table 1.
Higher contents than those listed in Table 1 should be determined according to ENV 13800.
