==================================
[size=+1] Composition of Sandwich Rubber (new provision to T4 Leaflet)
■ Under same model name (=brand name), sandwich rubber may have sponge of single type.
■ Within a type, the sponge may only differ in color and thickness.
■ If combined with sponge of another type, having different hardness, density, material, etc.,
the topsheet must be moulded with a new model name and new ITTF number; and the authorisation fees will be charged for each new model name in accordance with the ITTF Equipment Approval Policy (
T7 Leaflet)[/size]
===================================
FOR INTRODUCTORY PURPOSE ONLY>
For a better explanation, let's see ANDRO Rasanter series:
037 Rasanter R37 In
039 Rasanter R42 In
041 Rasanter R47 In
042 Rasanter R50 In
1) The features to note:
• One rubber topsheet of the same composition (material, pimples geometry, etc.)
• Sponge layer beneath the topsheet comes of 4 different types, with hardness degree of 37º 42º 47º 50º.
Accordingly, each sponge-topsheet combination got designed with a new Modell Name and new Registry Number.
2) Rasanter@ rubber series is meant to be a typical designation of sandwich rubber we propound for adoption on every rubber-applicant looking to gain ITTF approval.
NOTE OF IMPORTANCE: All the unrecognizable sandwich rubbers (complete checklist attached) should be eventually discontinued from retail market.
