At this position, an option (number or letter) selected from thespecification is displayed instead of the placeholders.
Basic specifications
The features that are absolutely essential for the device (mandatoryfeatures) are specified in the basic specifications. The number ofpositions depends on the number of features available.
The selected option of a feature can consist of several positions.
Optional specificationsThe optional specifications describe additional features for the device(optional features). The number of positions depends on the number offeatures available. The features have a 2-digit structure to aid
identification (e.g. JA). The first digit (ID) stands for the feature groupand consists of a number or a letter (e.g. J = Test, Certificate). The
second digit constitutes the value that stands for the feature within thegroup (e.g. A = 3.1 material (wetted parts), inspection certificate).
More detailed information about the device is provided in the following
tables. These tables describe the individual positions and IDs in theextended order code which are relevant to hazardous locations.
