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 barriers to prevent access to dangerous areas of the protective device (for example. meet the GB 18831 interlock protection device, or in line with GB/T 8196 solid (For example, GB/T 19436.1) or a pressure-sensitive protective device that complies with this part).

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. They pass through the interface and the machine controller is connected to ensure that once the pressure-sensitive device is driven, the machine returns to the safe state.

GB/T 17454 is limited to the design of pressure sensitive protection devices. In this way, the machine manufacturer carries out the risk assessment and/or related C class standards (If any) indicates that, if applicable, a pressure-sensitive protection device may be used.

Mechanical safety - Pressure - sensitive protective devices - Part 1.

Design and test of pressure - sensitive mats and pressure - sensitive floors

1 Scope

This part of GB/T 17454 specifies a device for protecting personnel from mechanical damage - usually a foot-driven pressure sensitive pad and pressure General principles and requirements for the design and testing of sensitive floors. This section gives the minimum safety of pressure-sensitive and pressure-sensitive floors, marking and documentation Claim.

This section applies to pressure sensitive pads and pressure sensitive floors designed to sense the following persons, regardless of their energy form (eg, electrical, liquid Pressurized, pneumatic or mechanical).

--- more than 35kg weight of the staff;

- persons weighing more than 20kg (eg children).

This part does not apply to pressure sensitive pads and pressure sensitive floors with a weight of less than 20 kg.

Since the following content depends on the specific application, this section does not provide for.

a) the size or structure of the sensitive area of the pressure sensitive pad or pressure sensitive floor associated with any particular application;

b) pressure sensitive pads or pressure sensitive floors to be used only in certain circumstances;

c) control the performance level (PL) of the system safety related components (SRP/CS), not the lowest level.

This section also provides guidance to assist users (ie, machinery manufacturers and/or machine users) to make adequate arrangements.
