Introduction

Electrically sensitive protective devices (ESPEs) are suitable for machinery that poses a risk of injury to humans. They can restore the machinery to its original state before a person is in a dangerous situation.

To reach a safe state, thereby providing protection.

This document specifies the general design and performance requirements for widely applicable electrically sensitive protective devices (ESPEs). Compliance with this document...

The basic characteristics of the equipment are that it has an appropriate safety-related performance level and a built-in cycle specified to ensure that this performance level is maintained.

Sexual function test or self-examination.

Each type of machinery has its specific hazards, and this document is not intended to recommend the use of electrically sensitive protective devices (ESPEs) on any particular type of machinery.

The method is the objective. The application of electrically sensitive protection devices is determined through consultation between the supplier of such devices, the user of the machinery, and the mandatory regulatory body. Regarding this...

One point to note is the relevant guidance documents that have been established both domestically and internationally, such as GB/T 15706-2012.

GB/T 19436 is proposed to consist of four parts.

---Part 1: General Requirements and Tests. For non-contact electrically sensitive protective devices specifically designed for detecting the human body or parts thereof.

ESPE (Enhanced Safety Specifications) defines general requirements for product design, manufacturing, and testing to ensure that electrically sensitive protection devices meet the necessary safety performance levels.

The aim is to improve the overall safety level of mechanical and electrical equipment and protect the personal safety of employees.

---Part 2: Special Requirements for Equipment Using Active Optoelectronic Protection Devices (AOPDs). Building upon Part 1, this section outlines specific requirements for equipment using...

Active photoelectric protection devices (ESPEs) further specify special requirements for product design, manufacturing, and testing.

Ensure that such electrical sensitive protection devices (ESPEs) meet specific usage requirements.

---Part 3: Special Requirements for Equipment Using Active Optoelectronic Diffuse Reflection Protection Devices (AOPDDR). Based on Part 1 the document further specifies the product design, manufacturing, and testing requirements for electrically sensitive protection devices (ESPEs) that use active photoelectric diffuse reflection protection devices.

Special requirements for testing ensure that such electrical sensitive protection devices (ESPEs) meet specific usage needs.

---Part 4: Special Requirements for the Use of Visual Protection Devices (VBPDs). Building upon Part 1, this section outlines specific requirements for the use of visual protection devices (VBPDs).

Electrically sensitive protective devices (ESPEs) further specify special requirements for product design, manufacturing, and testing to ensure the safety of such electrically sensitive devices.

ESPE (Enhanced Safety Equipment) meets specific usage requirements.

This document addresses the technical applicability of electrically sensitive protective devices (ESPEs). Unless adequate precautions are taken, the application of this document should be avoided.

The substances and testing methods used may be harmful to human health. Compliance with this document does not exempt the supplier or user from liability for any consequences arising from the use of these substances.

When using equipment, the legal responsibility for personal safety and health that one bears.

This document requires a high degree of analytical and professional knowledge regarding the specified testing and measurement techniques. To ensure a high level of reliability...

It is recommended that the relevant experts conduct an independent review.

Mechanical and electrical safety sensitive protection equipment Part 1: General Requirements and Testing

1 Scope

This document specifies the design, manufacture, and testing of non-contact electrically sensitive protection devices (ESPEs) specifically designed for detecting human bodies or parts of the human body.

In general, electrically sensitive protection devices are an integral part of safety-related systems. It is particularly important to ensure that, regarding their functions and design requirements, [the following is a continuation of the previous sentence].

Ensure that appropriate safety-related performance is achieved. Electrically sensitive protective devices (ESPEs) may include selective safety-related functions, the requirements of which are detailed in Appendix A.

The information is provided in the text.

Note. "Non-contact" means that the sensing does not require human contact.

This document is intended to be used in conjunction with the subsequent parts of GB/T 19436, which are based on specific requirements for sensitive technologies.

Example. This document and GB/T 19436.2 are for the use of active photoelectric protection devices (AOPDs); this document and GB/T 19436.3 are for the use of active photoelectric protection devices.

AOPDDRs (Aspect-Oriented Optimal Radiation Protection Devices).

If there is no section covering sensitive technologies, then use IEC TS62998-1.

If the GB/T 19436 series does not contain all the necessary provisions, then use IEC TS62998-1.

In addition to IEC TS62998-1, it can also be combined with the parts covered by the GB/T 19436 series.

This document does not specify the size or shape of the inspection area, nor its arrangement in any particular application where it involves hazards, nor does it specify what constitutes a hazardous area.

The dangerous condition of any machine is limited to the function of the ESPE and how it is connected to the machine.

Although the data interface can be used to control the selective safety-related functions of the ESPE (Appendix A), this document does not specify the specific requirements.

The requirements for these safety-related functions can be found by consulting other standards such as IEC 61508 (all parts), IEC 62046 and IEC 62061.

Determined by ISO 13849-1.

This document may relate to applications that are not for human protection, such as protecting machinery or products from mechanical damage. In these applications, Different requirements may be needed, such as materials that must be identified by sensitive functions and have some properties that are different from those of the human body.

This document does not cover ESPE functional requirements unrelated to human safety (such as navigation using sensitive cell data).

This document does not cover electromagnetic compatibility (EMC) emission requirements.
