1. Noise tube test method 2019. 01 Management Support Division 두리화학 주식회사 Draft. 1.0

2. 목 차 Vietnam Noise standard 2. German Noise tube test method (DIN 4109) 3. Korea Noise tube test method (KS)

3. 1. Vietnam Noise standard Ref. Product Wavin Dutch pipe specialist Reservoir series for civil engineering and wastewater Wavin AS Wavin SiTech , SiTech +

4. 1. Vietnam Noise standard 베트남 소음기준 Wavin Dependence on side data Wanic According to the data base of Germany noise standard DIN 4109 Flow rate 4.0 Liter/second 17.9dB And it is required to be less than the same standard.

5. 2 . German waste water pipe noise standard DIN 4109: 규정

6. 2. German waste water pipe noise standard DIN 4109: Test Set Up 유럽기준 한국기준

7. 2. German waste water pipe noise standard DIN 4109: Test Set Up Europe is more about single housing culture than apartment culture. The test criteria are based on single-family houses , Measured data based on living space. It is a totally different standard from Korea. In Korea, noise measurement:       Between the piping and the noise gauge       There are no shields, which is even worse.  Therefore , direct comparison is meaningless.

8. 3. Korean Wastewater Pipe Noise Standards 한국 : KS F 2871 2,700 2,200 180 180 1,000 측정위치 소음시험기준 : LH 전문시방서 51060 마이크로폰 : KS C 1505 마이크로폰 설치 (5 곳 )

9. 4. Comparison of Korea-Germany test standards 2,700 2,200 180 1,000 Measuring position Item Korea Germany (Europe) Measuring position Apartment standard floor (Upper floor is toilet) Lower floor of B1 (The upper floor is the basement one-floor toilet) Between noise source and measuring position barrier none Concrete wall 유량 양변기 (6L), 세면기 (6L), 욕조 (60L) 유량 : 0.5l/s, 1.0l/s, 2.0l/s, 4.0l/s

10. 5. Conclusion on waste water pipe noise specifications The noise regulations and measurement standards of waste water pipes in Korea and Germany (Europe) are different.   Direct comparison with specifications is unreasonable . (For Ex: Korea-Vietnam)
