This part of IEC 1068 specifies requirements for tapes woven on shuttleless looms for continuous filament polyester fibres. Nominal thicknesses of 0,13 mm to 0,25 mm and nominal widths of 15 mm, 20 mm and 25 mm are covered. The standard combinations of nominal thickness and nominal width are specified and an additional designation is included for tapes which, whilst complying with the majority of the requirements of this part, are supplied with non-standard widths. This part gives definitions, a designation and general requirements. Other parts of IEC 1068 are: - Part 2: Methods of test. - Part 3: Specifications for individual materials.
