Exterior Sound Level Measurement Procedure for Recreational Motorboats
This SAE Recommended Practice establishes the procedure for measuring the maximum exterior sound level of recreational motorboats while being operated under a variety of operating conditions. It is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances.
Rationale: This revision includes provisions for monitoring tests as well as type tests. Monitoring tests are particularly necessary in those jurisdictions where manufacturer certification of compliance with recreational motorboat sound level regulations is not required prior to sale. Consequently, monitoring tests are a necessary and important addition to this SAE Recommended Practice.
