It is essential that any BNWAS that you choose for your vessel meets with the performance standards set out by the IMO.
The performance standards for a bridge navigational watch alarm system (BNWAS) were outlined in Resolution MSC.128(75) and will form the basis of any Type Approval.
IEC is the world's leading organisation of international standards for all electrical, electronic and related technologies. IEC 62616:2010(E) specifies the minimum performance requirements, technical characteristics and methods of testing, and required test results, for a bridge navigational watch alarm system (BNWAS) as required by Chapter V of the International Convention for the Safety of Life at Sea (SOLAS), as amended. It takes account of the general requirements given in IMO resolution A.694(17) and is associated with IEC 60945. When a requirement in this International Standard is different from IEC 60945, the requirement in this standard takes precedence.
This standard incorporates the parts of the performance standards included in IMO resolution
MSC.128(75).
