5 Requirements
5.1 General
In addition to the requirements specified in EN 13920-1, the requirements given in 5.2, 5.3 and 5.4 shall be met.
If the scrap does not meet all these requirements, the supplier shall notify the deviating characteristics to the purchaser and shall obtain his agreement before shipment.
5.2 Characteristics
The scrap shall not contain more than 5 % (mass fraction) of oil, grease, dust, plastics and any other type of foreign non-metallic material as a total. The scrap shall be free from foreign metallic materials.
5.3 Chemical composition
If not otherwise agreed the chemical composition shall conform to the requirements given in one of the following Tables.
