For assessing the elastomer parts after the initial storage period, the following procedure is proposed:

1. Checks conducted against the applicable product specification
   If a measure of this kind is not provided for in the product specification concerned, then the following check routines should be performed.
   
   
2. Visual check
   Every part or every component in the representative sample must be Neoprene checked to look for:
   - Permanent deformation, such as wrinkles or flat areas
   - Mechanical damage like cuts, cracks, abraded areas or detached layers
   - Crack formation at the surface, observed under a magnifying glass with   10- fold magnification
   - Changes in the state of the surface, like hardening, softening, tackiness,   discoloration and soiling.

A record must be kept of the features checked for the parts or components stored.
