Foreword

GB/T 19322 "small boat motor yacht air noise" is divided into three parts. --- Part 1. Pass the measurement procedure; --- Part 2. Noise assessment using standard boats; --- Part 3. Calculation and measurement procedures for noise assessment. This section GB/T 19322 Part 3. This section drafted in accordance with GB/T 1.1-2009 given rules. This section uses the translation method identical with ISO 14509-3.2009 "Small motor yacht airborne noise Part 3. Calculation and measurement Procedure for noise assessment "(in English). The documents of our country that are consistent with the corresponding international documents that are normative references in this section are as follows. --- GB/T 3785.1-2010 Electroacoustic sound level meter Part 1. Specification (IEC 61672-1.2002, IDT) --- GB/T 11700-2009 Small craft marine propulsion reciprocating internal combustion engine power measurement and calibration (ISO 8665.2006, IDT) --- GB/T 15173-2010 Electroacoustic sound calibrator (IEC 60942.2003, IDT) --- GB/T 16696-2008 Small boat body identification code (ISO 10087.2006, IDT) --- GB/T 19916-2005 boat main data (ISO 8666.2002, IDT) This part is proposed by China State Shipbuilding Corporation.
