BS EN 15860:2010 pdf free download Plastics — Thermoplastic semi-finished products for machining — Requirements and test methods
This European Standard specifies the requirements and associated test methods that apply to semi-finished products such as rods, hollow bars and plates made from thermoplastic materials. These semi-finished products are used predominantly for the manufacture of finished parts by means of machining.

4Materials
The semi-finished products shall be made of thermoplastic materials (see Table 1).These materials maycontain additives such as processing aids,reinforcing agents,fillers,stabilizers or colorants, in whichcase, they are further referred to in this standard as “modified materials”.
The nature and the quantity of these additives can influence the mechanical,thermal and electricalproperties of the semi-finished products.The choice and the quantities of additives used are left to thediscretion of the manufacturer of the semi-finished products.
