Low-voltage switchgear and control gear, particularly Part 5, function as an indispensable component in the safety and dependability of electrical systems. In this context, Electrical Emergency Stop Devices with Mechanical Latching Functions are functional and necessary components in order to gain immediate control in emergency conditions. They are designed to stop the operation of machines instantly so that the reduction of risks to people’s lives and machinery is achieved. For instance, the BIS has set high specs in IS/IEC 60947 standards for these gadgets to meet performance and safety benchmarks to protect industrial settings.
In India, such standards are instrumental for manufacturers who aim to produce standard and reliable emergency stop devices. However, the mechanical latching function is relevant since it is designed to keep the gadget locked starting in the active position until unlocked with the push button, while the device wants to be disarmed by pressing the same control again. This blog will provide information about the manufacturing processes of these devices, their performance requirement, testing procedures, and BIS certification. Knowledge of such aspects also leads to understanding their significance and at the same time reveals the concern with quality and safety in the industrial context of India.
BIS Registration Sample
Low-voltage switchgear and control gear (LVSG) is switching and protective equipment used for operating electrical circuits and apparatus. Section 5 of Part 5 of the relevant standards deals with Control Circuit Devices and Switching Elements in particular with Electrical Emergency Stop Devices with Mechanical Latching Function. These devices are important in safety measures for various operations in industries and commerce because they afford a safety method of halting machines or equipment whenever operations become risky.
The BIS has laid down rules in detail under the IS/IEC 60947 with an objective to protect the devices from adverse factors and maintain safety and standard performance levels. The mechanical latching function is specifically critical because the emergency stop engages and stays active until the operator manually resets it on the machine.
The manufacturing process for electrical emergency stop devices typically involves several key stages:
This process is quite effective because it not only checks whether the right functions are provided in the devices but also checks whether the devices are safe to use as projected by BIS standards.
Performance requirements for electrical emergency stop devices include:
Testing methods typically involve:
It helps in ensuring that these equipment are safe as certified by BIS with regard to the tests that are undertaken.
The testing methods for electrical emergency stop devices include:
Ensuring that the product has no physical flaws or production mistakes.
Measuring the current, voltage, and resistance of the electrical circuits.
Evaluation of mechanical parts’ performance under load conditions.
Assessing its capabilities and reliability in case of emergency in order to make sure that is safe enough.
All the methods are important to guarantee the safety of the devices for usage in industrial settings.
To conduct testing on the Low-Voltage Switchgear and Controlgear Part 5 Control Circuit Devices and Switching Elements Section 5 Electrical emergency stop devices with mechanical latching function effectively, laboratories must adhere to specific requirements:
Labeling and markings are fundamental requirements of BIS standards regarding specifications for Low-Voltage Switchgear and Controlgear Part 5 Control Circuit Devices and Switching Elements Section 5 Electrical emergency stop devices with mechanical latching function. Each product must include:
The following are the given documents for BIS Certification:
| General Documents | Technical Documents |
|---|---|
| Business License | Plant Layout |
| Trademark License | List of Manufacturing Equipment |
| Application Form | Manufacturing Process Flow Chart |
| Authorization Letter | Product Literature |
| Laboratory Test Reports | List of testing equipment and machinery |
| MSME certificate | Product’s technical Specification |
| List of calibration certificate |
The BIS certification process for Low-Voltage Switchgear and Controlgear Part 5 Control Circuit Devices and Switching Elements Section 5 Electrical emergency stop devices with mechanical latching function involves several steps:
Applications are filled including relevant documents that outline the production processes of the manufacturers.
A BIS officer pays a visit to the manufacturing company in order to assess the levels of compliance with set regulations.
The samples from the production batches are analyzed at the BIS-accredited laboratories.
As a result of the evaluation of these facilities and products, BIS grants permission to the manufacturers to use the ISI mark on their products.
To sustain the standards practice, normal assertions are carried out.
This is a process that the manufacturers need to understand so that they can get an efficient certification process.
Importance of BIS Certification
BIS certification is crucial for several reasons:
Conclusion
Altogether, emergency stop devices integrated into electrical systems with mechanical latching functions are highly important to eliminate risks within industrial surroundings. Due to the characteristics of the emergency lighting applications, such requirements formulated by BIS under IS/IEC 60947 Part 5 Section 5 are quite stringent such that these devices can offer high reliability and effectiveness in emergencies. The entire manufacturing process, proper test techniques, and compulsory certification standards not only safeguard consumers but also improve the general standard of products in the growing industrial sector in India. While manufacturers grind through the compliance issues of Quality Control Orders (QCOs) these standards make them crucial in the marketplace.
At Professional Utilities, we leverage our industry knowledge and expertise to help businesses navigate complex regulations, minimize risks, and optimize operations for maximum efficiency and profitability.
An electrical emergency stop device is a safety device that must stop the work of machinery at the first sign of an emergency.
Mechanical latching operating enables the emergency stop and holds it until it is reset, eliminating chances of accidental operation.
Manufacturers seeking to be certified by BIS have to fill out an application form together with the necessary documents to BIS, where it will be tested.

They've been very helpful in our registration with ICEGATE. It was a small thing with a small amount paid which somehow escalated to a very painful procedure. Never did they say "You've only paid so much. It's too much effort for us.".
Very pleased with their service. Prompt, professional and great communication. Definitely recommend. Special mention for Ms. Razia - she handled our case.
Professional Utilities is fully professional in their work, Rates are too low and genuine. Services and satisfaction are high so I highly recommended Professional Utilities.
They are one of the most genuine and reasonable people. I applied for lmpc certificate through them and they charged me a very nominal amount as compared to what other firms asked .
