approvals, and standards is included in the 
declaration of conformity.
By using the GL symbol
1)
, we confirm that the 
marked products were type tested according to 
the guidelines of Germanischer Lloyd.
The type approval is authenticated with a 
certificate.
The verified test requirements cover the 
environmental category "D" (closed 
environments with increased heat and vibration 
requirements).
Therefore, the marked products can be used 
according to the specifications of the certificate 
on ocean-going and inland vessels and on 
offshore operations in systems subject to 
mandatory type-testing.
