The enhanced visibility equipment is grouped into three types based on the foreseeable conditions ofuse:
Equipment worn by users where the risk of not being seen exists only at daylight conditions. Thisequipment uses only the fluorescent material as enhanced visibility component.
– Type B
Equipment worn by users where risk of not being seen exists only at dark conditions. Thisequipment uses only the retroreflective material as enhanced visibility component.
Type B is subdivided in 3 levels, as below.The classification depends on the total area worn or onplacement of the device on user’s torso and limbs:
– Type B1 includes free-hanging retroreflective devices only; these devices are designed for
– Type B2 includes retroreflective devices or retroreflective material either temporarily or
permanently placed on limbs only; these products are designed for movement recognition.As a
minimum, the retroreflective material shall be positioned on the limbs as a separate removabledevice or shall be incorporated into clothing design on a permanent basis as a retroreflectiveelement.
Type B3 includes retroreflective material placed on torso or torso and limbs. These productsare designed for form recognition, or form and movement recognition.Type B3 items shall notbe a combination of permanently attached reflective material and removable reflective devices.NOTE1 Additional retroreflective or combined-performance materials can be incorporated into garments.- Type AB
Equipment worn by users where risk of not being seen exists during daylight, twilight and darkconditions. This equipment uses the fluorescent as well as the retroreflective and/or combinedperformance materials as enhanced visibility components.
Table 1 shows the different types.
