Safety Fittings are identified by a batch marking.
This reads from left to right:
• Production week (KW) (stamp 1+2)
• Production year (stamp 2)
• Material identification letter (stamp 3)

The FRIALEN
®
Safety Fittings can be stored and processed for a long time,
provided the general storage specifications are adhered to. When properly
stored (in closed rooms or containers (boxes)) and/or not exposed to UV
radiation as well as effects of weather (humidity etc.), a storage and
processing period of more than 4 years can be assumed.
WARNING!
Improperly stored component parts may not be processed because
this may result in leaking fusion joints.
Traceability
An automatic component traceability is possible when using e.g. traceability-
capable FRIAMAT
®
Electrofusion Units with a special barcode (see Figure 9)
which contains the specific data of the fitting, e.g. manufacturer, dimension,
material, batch. These data on component traceability can be electronically
archived together with the fusion process data.
IMPORTANT!
Manual electrofusion units (without barcode reader), e.g. FWS 225, are
no longer state-of-the art. Processing of FRIALEN
®
Safety Fittings with
these units is thus no longer possible.
