Foreword
This standard is modified using EN14366..2004 "laboratory measurement of wastewater noise" (Laboratorymeasurementofnoise
fromwastewaterinstalations). The main technical differences from EN14366..2004 are as follows.
--- According to the Chinese habit of some layout format has been modified;
--- Increasing the drainage pipe system terms and definitions;
--- Remove the rain down the pipe test application;
--- Increasing the number of test microphone position, the choice of requirements, while increasing the average sound pressure level terms, definitions and algorithms
formula;
--- Modify the distance between the bottom elbow and the floor to suit China's national conditions;
--- Modify the test laboratory floor, while increasing the number of laboratories in order to achieve the same time test the drainage of adjacent two layers
The influence of noise
--- Increasing the application of the test method for the noise generated by the drainage pipe system containing sanitary appliances;
--- Increased inspection report reference format.
Appendix A of this standard is a normative appendix, Appendix B and Appendix C are informative appendices.
