Introduction

Machinery safety standard is structured as follows.

--- A class standard (basic safety standards) give basic concepts apply to all mechanical, design principles and general characteristics.

--- B class standard (generic safety standards), it relates to a mechanical safety feature or use a wide range of safety devices for a class.

* B1 class, specific security features (e.g., safety distance, surface temperature, noise) standard;

* B2 class, the safety device (such as a hand control devices, interlocking devices, pressure sensitive devices, guards).

--- C class standards (machine safety standards), for a particular machine or group of machines shall specify detailed safety standard requirements.

According to GB/T 15706.1, this section is a Class B standards.

Class C standard may supplement or modify the terms of this section.

For Class C in accordance with the standard design and construction of the machine, if the C class standards in terms of Class A or Class B standards are inconsistent, priority

Using C standard.

Hazardous Substances Safety of machinery airborne

Assessment of emissions - Part 3. Measuring a given pollutant

Emission rate, test bench method

1 Scope

This section GB/T 25749 specifies the machine under specified operating conditions, measuring airborne emissions of harmful substances from the machine

Rate, test bench method.

Measuring machine emission rate of a given pollutant emissions can be used.

a) evaluate the performance of the machine drainage system;

b) assessment of machine emissions reduction;

Comparison within the machine c) the intended use of the machine with the same group between (defined by the functional group of machines and materials processing);

d) in accordance with the emission rate for the same group of machines machines are classified;

e) in accordance with the emission rate to determine the technical level of the machine.

This section does not apply to the manufacture of machinery prior to its release.
