Summary This standard specifies the general principles and requirements for the design and testing of pressure sensitive and pressure sensitive rods used as safety guards rather than as conventional operating actuators. This standard applies to pressure-sensitive and pressure-sensitive rods with or without external resetting devices for sensing human or human parts exposed to hazards (eg hazards caused by moving parts of the machine). This standard does not apply to: - Determines whether a pressure sensitive or pressure sensitive rod is suitable for a particular safety protection; - Selects the appropriate performance level (PL) for the control system safety related components (SRP/CS), rather than giving the minimum; - determining the size or structure of the sensitive sensitive area or pressure sensitive rods sensitive to sensitive areas associated with any particular application; - a stop device in accordance with GB 5226.1 and only for normal operation of the machine,

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 and pressure-sensitive rods are "mechanical drive trip device" safety devices. GB/T 15706-2012, 6.3.1 and 6.3.2 are given The general requirements for such safety guards (and other safety devices). Pressure-sensitive and pressure-sensitive rods are widely used in extreme loads, electrical, physical and chemical environments. They pass through the interface And the machine controller connected to ensure that once the pressure-sensitive device is driven, the machine back to a safe state. This part is limited to the design of pressure sensitive edges and pressure sensitive rods. In this way, the machine manufacturer's risk assessment and/or related Class C criteria (if any) Indicating that applicable, can be used pressure-sensitive and pressure-sensitive rods. The pressure-sensitive and pressure-sensitive rods can be mounted on machine fixed or moving parts and can also be installed in the machine to prevent other parts of the machine into or squeeze Pressure on the obstacle. The design, selection, installation and/or connection of the pressure sensitive side and the pressure sensitive rod to the machine control system makes it possible to apply to the human body or person The force/pressure of the body part does not exceed a certain limit. There are many similarities between pressure sensitive edges, pressure sensitive rods, pressure sensitive buffers and similar devices. Table 1 summarizes the two types of pressure covered by this section Sensitive devices and pressure sensitive buffers (covered by GB/T 17454.3, and gives their application guidelines).

1 Scope

This part of GB/T 17454 specifies the use of pressure-sensitive and pressure-sensitive rods as safety guards rather than as conventional operating actuators The general principles and requirements of design and testing. This section applies to with or without external resetting means for sensing exposure to hazards (eg hazards caused by machine moving parts) Human or human parts of the pressure-sensitive side and pressure-sensitive rods. This section does not apply to. - determine whether the pressure sensitive edge or pressure sensitive rod is suitable for specific safety protection; - select the appropriate performance level (PL) for the control system safety related components (SRP/CS) instead of giving the minimum value; - determining the size or structure of sensitive sensitive areas or pressure sensitive rods associated with any particular application; A stop device that complies with GB 5226.1 and is only used for normal operation of the machine, including a device for emergency shutdown of the machine. This section gives the information required to be provided by the manufacturer in order to assist in the selection of suitable pressure sensitive and pressure sensitive rods and to apply them correctly. In the elderly, people with disabilities or children easy to access the use of pressure-sensitive side and pressure-sensitive rods, need to consider additional requirements.
