Plastics — Polyethylene (PE) moulding and extrusion materials — Part 1: Designation system and basis...
The types of polyethylene plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties density and melt flow rate and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. Is applicable to materials ready for normal use in the form…
Information technology — 3,81 mm wide magnetic tape cartridge for information interchange — Helical ...
Specifies the physical and magnetic characteristics. Also specifies the quality of the recorded signals, the recorded format and the recording method, thereby allowing data interchange between drives by means of such magnetic tape cartridges. Specifies two types of cartridges referred to as type A (magnetic tape of nominal thickness of 13 µm and a nominal length of up to 60,5 m) and type B (…
