Introduction of a 5 year validity
A newly published regulation in Trinidad and Tobago, states that Type Approval certificates will be changed from unlimited to a 5 year validity.
This change does not only affect new certificates, but all certificates.
The 5 year validity term will be calculated from the day of issuance, meaning that certificates older than 5 years are now not valid anymore.
Renewals are possible.
Attached is the official document, issued by the Telecommunications Authority of Trinidad and Tobago.
The relevant paragraphs, regarding time limitations, can be found on page 17, section 3.6.
