1.1 This Part 3 of EN 13417 defines a specification for woven fabrics made from continuous filament reinforcement yarns, tows and rovings, which may be used as the basis for specifications.
The specification defines those parameters which shall be specified plus other parameters which may be specified if required for a particular application or processing method.
1.2 The specification does not define absolute or nominal values for any parameter. The value of a specified parameter is to be defined by the manufacturer but this specification defines the method of test to be used to determine the value of each specified parameter and the tolerance about which the parameter shall be controlled by the manufacturer.
1.3 The parameters which shall always be defined in any woven reinforcement fabric specification are defined in 4.1. In 4.2 the manufacturer shall define other obligatory information to be included in the specification. Other parameters can be included in the specification by agreement between manufacture and customer. These parameters are defined in clause 4.3.
