Introduction

The mechanical safety standards are structured as follows.

- Class A standard (basic safety standard), given the basic concepts, design principles and general characteristics applicable to all machinery;

- Class B standard (general safety standard), a safety feature involving a mechanical or a wider range of safety devices.

- Class B1, specific safety features (eg safety distance, surface temperature, noise) standard;

- B2 class, safety devices (such as two-hand control device, interlock device, pressure-sensitive devices, protective devices) standard.

- Class C standards (mechanical product safety standards) that specify a detailed safety requirement for a particular machine or group of machines.

According to GB/T 15706, this part belongs to class B2 standard.

This section relates in particular to the following trade safety-related stakeholders.

--- machine manufacturer;

--- health and safety institutions.

Other stakeholders affected by the level of mechanical safety are.

--- machine use personnel;

--- machine owner;

--- service provider;

- consumers (for machines intended for use by consumers).

All of these stakeholders are likely to participate in the drafting of this section.

In addition, this part is intended for the standardization of institutions for the drafting of Class C standards.

The requirements specified in this section may be supplemented or modified by Category C standards.

For machines that are designed and manufactured in accordance with Category C standards within the scope of Class C standards, the requirements in Class C standards are preferred.

Many different methods can achieve mechanical safety protection (see GB/T 15076-2012,3.21). These methods include by setting Physical barrier Prevents access to hazardous areas (eg GB/T 18831 interlocking guards, or GB/T 8196 Fixed protective devices), protective devices (for example. GB/T 19436.1 in line with the protection of electrical equipment, or in line with this part of the pressure-sensitive protective equipment Set).

Designers of Class C standards and designers of machinery/equipment are considered to be considered when considering the required level of safety through the best route Use and risk assessment (see GB/T 15076).

The solution required is probably to consider several of these methods, so before deciding which security guards are to be selected, it is advisable for the suppliers and users of the machinery/equipment to carefully examine the risks and limitations.

Pressure-sensitive protection devices are widely used in extreme load, electrical, physical and chemical environments and other related conditions. If the pressure sensitive device is Driven by the interface and the machine controller connected to ensure that the machine back to a safe state.

This part is limited to the design of pressure sensitive protection devices. In this way, the machine manufacturer carries out the risk assessment and/or the relevant C standard (eg If applicable), it is possible to use a pressure-sensitive protection device.

This section does not specify the size and structure of the sensitive area of the pressure sensitive device associated with any particular application. However, any security guard is required the device manufacturer provides sufficient information to allow the user (ie the machine manufacturer and/or the user) to make provision for adequate arrangements.

The driving force of the pressure-sensitive protective device specified in this part is based on the information available at the time of publication of this part. Need to have been so driven Power to review, which can be considered further study in the case of no major damage can be imposed on the human body on the force.

While these forces can provide a practical method for the design and testing of pressure sensitive devices, they are not intended to prevent damage in all applications. Stipulate A particular device or application of the driving force, it is appropriate to consider a number of factors, including contact area, contact speed, the use of materials and the affected people Body parts.

1 Scope

This part of GB/T 17454 gives instructions for use with GB/T 17454.1 or GB/T 17454.2 with or without external resetting device of the general rules and requirements for pressure sensitive protection devices. Most of these pressure-sensitive protective devices are customized for specific applications and can not in the form of "standard stock".

This part also gives the following specific requirements for pressure-sensitive protection devices.

a) pressure sensitive buffer;

b) pressure sensitive board;

c) pressure sensitive line (trigger line).

This section deals with the safety and reliability design issues of pressure sensitive devices, rather than the suitability of application.

Note 1. The relationship between safety and reliability is given in 4.2 of IEC 61850-7-1.

Note 2. It is the responsibility of the machine manufacturer and/or the user to install the appropriate protective device according to the risk assessment.

This section does not apply to.

- Specifies the size of the pressure sensitive protection device associated with any particular application;

--- for the normal operation of the GB 5226.1 meet the stop device, including emergency shutdown.

Note 3. Specific requirements for specific applications are scheduled by the relevant Class C criteria (see GB/T 15706 and Introduction).

If the pressure-sensitive protection device is used for older persons, with disabilities or children are easily accessible, additional requirements are required.

Note 4. Although the electromagnetic interference requirements of the device have been given, it does not cover all the requirements of electromagnetic compatibility (EMC).
