적용 범위

This standard establishes the maximum noise level limits for inland waterway ships operating in China. It applies to various vessel types, including dry cargo ships, liquid cargo ships, container ships, passenger ships, push (tow) boats, Ro-Ro ships, high-speed ships, and dredgers. Other inland vessels may refer to this standard for compliance, although specific exclusions exist for certain high-speed craft classifications.

기술 요구 사항

The standard categorizes inland ships into three classes (I, II, and III) based on ship length and continuous navigation time. It mandates strict A-weighted sound pressure level limits for different onboard compartments. Key regulated areas include the machinery spaces (such as manned engine control rooms and workshops), navigation areas (like the wheelhouse and radio room), and accommodation spaces (including bedrooms, medical rooms, offices, and galleys). Compliance with these specific compartment limits is mandatory for all applicable vessels. Additionally, the standard sets distinct, tiered noise limits for high-speed passenger cabins depending on their continuous navigation duration.

시험 방법

Noise measurement procedures must be conducted in accordance with GB/T 4595 (which is identical to ISO 2923:1996). The standard also mandates specific safety protocols: crews entering spaces with noise levels exceeding 90 dB(A) must wear ear protection, and prominent warning signs must be displayed at the entrances to these high-noise zones.

자주 묻는 질문

What types of vessels are regulated under GB 5980-2009?

This standard applies to various inland waterway vessels including dry cargo ships, liquid cargo ships, container ships, passenger ships, push/tow boats, Ro-Ro ships, high-speed ships, and trailing suction/hopper suction dredgers. Other inland vessels may refer to this standard for compliance.

Are there any significant updates in GB 5980-2009 compared to the previous GB 5980-2000 version?

The updated version adjusts the ship length classification threshold from 75m to 70m and refines the terminology to continuous navigation time. It also modifies the maximum noise limits for specific areas, such as lowering the limit for Category I and II engine control rooms to 75 dB(A) and reducing the Category II kitchen limit to 80 dB(A).

How is onboard noise measured according to this Chinese standard?

The noise measurement procedures must comply with GB/T 4595, which is identical to the international standard ISO 2923:1996. Engineers should ensure testing protocols align with these recognized measurement standards.
