Escopo e aplicabilidade

This standard is established to control environmental vibration pollution in urban areas. It applies to various urban zones, including residential, commercial, industrial, and traffic-adjacent areas. The standard is mandatory for assessing environmental vibration impacts in city environments. It specifically regulates vibration levels for areas such as special residential zones, mixed-use districts, and areas adjacent to traffic arteries and railway lines. It does not apply to non-urban or rural environments.

Requisitos técnicos

The standard specifies the vertical Z vibration level limits for different urban zones, categorized by daytime and nighttime periods. It defines specific limit values for areas requiring particular quietness, such as special residential areas, as well as for industrial zones and areas alongside railway lines. The standard values apply to continuous steady-state vibrations, impact vibrations, and random vibrations. For impact vibrations occurring a few times a day, the standard imposes stricter maximum limits, allowing daytime exceedances of no more than 10dB and nighttime exceedances of no more than 3dB above the baseline. Local governments are responsible for designating the specific applicable zones and defining the exact daytime and nighttime hours based on local customs and seasonal changes.

Métodos de ensaio

Measurement points are typically located at vibration-sensitive areas within 0.5m outside the building, or at the center of the indoor ground floor if necessary. The measurement of the vertical Z vibration level and the calculation of evaluation quantities must be conducted in accordance with the relevant provisions of GB 10071, which is the referenced standard for urban environmental vibration measurement methods.

Perguntas frequentes

What products or activities are regulated under GB 10070-88?

GB 10070-88 regulates environmental vibration pollution in urban areas. It applies to activities generating steady-state, impact, or random vibrations that affect designated urban zones, including residential, commercial, and industrial areas, as well as vicinities of traffic and railway lines.

How are daytime and nighttime periods defined in this standard?

The standard does not specify fixed hours for daytime and nighttime. Local People's Governments are responsible for determining the specific daytime and nighttime hours according to local customs and seasonal variations.

What are the specific requirements for impact vibrations?

For impact vibrations occurring a few times daily, the maximum values must not exceed the standard baseline limits by more than 10dB during the daytime and 3dB during the nighttime.
