3.1 Marking of Buffer Rings
The buffer rings are marked on the face of one buffer element as follows:
-
Coupling size and material abbreviation (Vk for Polyurethane or Pb for Perbunan)
-
Year of construction
-
Pb72 = buffer ring of Perbunan, 72 Shore(A) / black
-
Pb82 = buffer ring of Perbunan, 82 Shore(A) / black
-
VkB = buffer ring of Polyurethane, 83 Shore(A) / blue
-
VkR = buffer ring of Polyurethane, 93 Shore(A) / red
-
Vk60D = buffer ring of Polyurethane, 60 Shore(D) white/beige
4 Storage
On receipt of the goods, immediately check that all parts are on hand and are as ordered.
Eventual shipping damages and/or missing parts have to be reported in writing.
The coupling parts can be stored in the delivered state in a dry place under roof at normal
ambient temperatures for a time period of 6 months. Storage for a longer period requires the
application of a long-term preservation. (Please consult TSCHAN GmbH in this respect.)
The buffer rings must not be exposed to ozonic media, direct sun light or intensive light
sources with UV light. The air humidity should not exceed 65 %. If the parts are properly
stored, the quality characteristics of the elastic buffer rings remains almost unchanged for up
to three years.
