Foreword
This Standard is drafted according to the rules of GB/T 1.1-2009.
This Standard replaces TB/T 3122-2005 Technique requirements and
measurement of acoustic elements of railway sound barrier.
Compared with TB/T 3122-2005, the major technical changes are as follow.
— MODIFY the terms and definitions of "deformability" to the terms and
definitions of "wind load resistance performance"(see 3.7);
— MODIFY the noise reduction coefficient
of acoustic elements laboratory tests and weighted sound
reduction requirements (see 4.1.1);
— DELETE the "Installation" clause of the "technical performance
requirements" (see 4.8 of TB/T 3122-2005);
— MODIFY the standards based on test methods
of laboratory absorption properties and sound reduction properties
(see 5.1 and 5.2);
— PROVIDE specific requirements in the requirements and test methods
of anti-corrosion performance (see 4.1.5 and 5.6);
— ADD the requirements and test methods of fatigue resistance
of acoustic elements (see 4.1.6 and 5.7);
— ADD the supplementary requirements of organic synthesis transparent
plate of acoustic elements (see 4.9 and 5.9);
This Standard is under the jurisdiction of the Energy-Saving Labor Health
Research Institution of China Academy of Railway Science.
This Standard is drafted by Energy-Saving Labor Health Research Institution
of China Academy of Railway Science and Taixing Tomson Acrylic Ltd.
This Standard is mainly drafted by He Binzhe, Yin Hao, Ma Yun, Tang
Yuesheng and Zhu Zhengtong.
This Standard was first published in June 2005, and this is the first revision.
