BS EN 643-2002 pdf download.Paper and board European list of standard grades of recovered paper and board.
This BS EN 643 specifies European Standard grades of recovered paper and board which gives a general description of the standard grades by defining what they do and do not contain.
It is not the purpose of this European Standard to specify all the qualities of recovered paper and board that exist in the different markets, but rather to define those qualities most commonly traded in Europe. The description of the standard grades is brief, and for this reason it is recognised that specific deals between buyer and supplier for standard grades with special specifications will still be necessary to meet individual requirements and will not be excluded by any implied regulations associated with the publication of this European Standard.
This list contains a group of recovered paper grades (Group 5 “Special qualities”) that, in most cases, can only be recycled using specific processes, or can cause some particular constraints to recycling. Their inclusion in the list is justified by the existence of a significant European market. Actual recycling of the qualities can only be done by a limited number of mills located in a few countries only.
Recovered paper from refuse sorting stations is not suitable for use in the paper industry.
2 Terms and definitions
For the purposes of this European Standard the following terms and definitions apply:
unusable material
material unusable in the production of paper and board. It consists of “non-paper components and paper and board detrimental to production”. Recovered paper and board should in principle be supplied free of unusable materials, but where for specific grades a certain proportion of unusable materials is agreed between purchaser and supplier, it shall refer solely to the element described as “paper and board detrimental to Production”
non-paper components
consist of any foreign matter in the recovered paper and board which, during processing, may cause damage to machines or interruptions to production or may reduce the value of the finished product. such as:
— metal;
— plastic;
— glass;
— textiles;
— wood:
— sand and building materials; synthetic materials;
— synthetic papers.
paper and board detrimental to productIon
grades of paper and board wNch have been recovered or treated in such a way that they are, for a basic or standard level of equipment, unsuitable as raw material for the manufacture of paper and board, or are actually damaging, or whose presence makes the whole consignment of paper unusable
A growing number of mills have, however, adapted treatment plants to handle such grades, and the range of papers and boards capable of being recycled is increasing all the time as technology develops The criteria for defining the percentage of “unusable materials” for these grades will be subject to individual mills’ specifications.
3 Grade Identification
Recovered paper and board is graded as follows:
Group 1: ordinary grades;
Group 2: medium grades;
— Group 3: high grades; Group 4: kraft grades;
Group 5: special grades.
4 Moisture content in recovered paper and board
Recovered paper and board will, in principle, be supplied with moisture of not more than the naturally occuring level. Where the moisture content is higher than 10 % (of air dried weight), the additional weight in excess of 10 % may be claimed back – with the method of testing and sampling to be agreed between buyer and seller.
6 Quality classification of raw materials
6.1 Group 1, ordinary qualities
1.01 Mixed paper and board, unsorted, but unusable materials removed
A mixture of various grades of paper and board, without restriction on short fibre content.
1.02 Mixed papers and boards (sorted)
A mixture of various qualities of paper and board, containing a maximum of 40 % of newspapers and magazines.
1.03 Grey board
Printed and unprinted white lined and unlined grey board or mixed board, free from corrugated material.
1.04 Supermarket corrugated paper and board
Used paper and board packaging, containing a minimum of 70 % of corrugated board, the rest being solid board and wrapping papers.
1.05 Old currugated containers
Used boxes and sheets of corrugated board of various qualities.
1.06 Unsold magazines
Unsold magazines, with or without glue.
1.06.01 Unsold magazines without glue
Unsold magazines without glue.BS EN 643-2002 pdf download.
