In the field of architectural design and construction, ease of use and safety of heavy doors is crucial. One critical component that ensures these doors operate smoothly and securely is the hydraulic floor spring, specifically, those adhering to the Indian Standard IS 6315:1992. These devices are constructed to handle high-traffic doors, giving the door closer mechanisms that reduce slamming and increase user-friendly options. With the increasing demand for robust and reliable door systems in commercial and residential buildings, understanding the specifications and performance requirements outlined in IS 6315:1992 becomes critical for manufacturers, architects as well as builders throughout the world.
In this blog, we will be looking at the hydraulic floor springs that have to conform to the BIS standards that exist in India and more specifically we will look at aspects such as the performance measures, and testing methodologies that are normally used on the hydraulic floor springs, the laboratory standards that should be used for testing the springs, the labeling requirements as well as the certification that is usually accorded to the springs. We will also explain how getting BIS certification is essential in guaranteeing quality and safe products. Through examining these aspects, this paper seeks to give an exhaustive account of hydraulic floor springs to assist the stakeholders in making the right decisions in their uses. No matter what side of the fence you sit on, manufacturer or consumer, this guide is designed to bring light to how important these components are in today’s construction market.
The IS 6315:1992 standard of specifications for hydraulically operated floor springs for heavy doors. This standard provides minimum specifications for the design, fabrication, and performance of hydraulic floor springs for the intended use of doors particularly where heavy doors are used. The standard is very important for manufacturers and suppliers in India since it helps to check products and market them based on their safety and performance.
Regarding multi-leaf doors, the standard holding to the fact that the floor springs should be able to support the doors with a total weight of up to 125 kg for every individual door leaf. This capacity is very crucial in order to guarantee that the door will operate in the sort of way it is needed when encountering all sorts of situations. Additionally, IS 6315:1992 provides requirements to the material used in manufacturing the above devices with key parameters of reliability and durability.
The performance requirements outlined in IS 6315:1992 the emphasis was placed on a few major directions:
Latching Action: When the door is closed, the device should enable a safe lock.
Durability: Floor springs should perform this duty repeatedly without show of tear or lack of effectiveness.
To support these performance requirements, certain test procedures are applied. These tests enable the identification of the hydraulic mechanism’s effectiveness and the floor spring’s general performance under operational conditions.
Testing methods for hydraulic floor springs as per IS 6315:1992 include:
Static Load Testing: This involves applying a static load to the floor spring in order to determine if it is capable of bearing that load without suffering any deformation.
Dynamic Testing: Acting out real door usage to test the speed at which doors close, how they latch, and whether they are robust.
Environmental Testing: Assessing the degree to which the effectiveness of the floor spring in operation may be managed by the fluctuations in the physical environment such as the amount of heat and moisture in the air.
These testing methods are sacrosanct in establishing that products not only conform to existing legal and industry compliance benchmarks but also satisfactorily to other actual uses.
Testing labs for plastic shoes need to follow certain rules:
Equipment: They must have the right tools that are checked and can do all the tests needed as per IS 6315:1992.
Qualified Staff: The people working there should have the right skills and training to do the tests correctly.
These rules are important to make sure the testing process is good and the results are reliable.
Proper labeling and marking are critical for identifying Door closers and hydraulically Regulated Door Closers with IS 6315:1992. The standard specifies several key labeling requirements:
What Should Be on the Labels
Each article of Door closers, Hydraulically Regulated Door Closers must be marked with the following information:
Manufacturer's Name or Logo: This shows who made the Door closers, Hydraulically Regulated Door Closers.
Size Number: This explains the dimensions of the sole.
Batch Number: This serves to monitor the quality production batch.
Month and Year of Production: This is a testament to the time when the product was produced
ISI Mark: This verifies that the product falls within the specifications of BIS.
Also, the packaging must follow BIS rules to ensure safe handling and storage during shipping.
The following are the required documents for BIS certification:
| General Documents | Technical Documents |
|---|---|
| GST Certificate | Raw Material List |
| MSME Or Udyam Certificate (Not applicable for large-scale industries) | Raw Material Test Certificate |
| Manufacturing land details (Lease Deed/ Rent agreement) | Plant Layout (Lab, Office, Raw material area, Finished Goods area) |
| MOA/AOA (If Private Limited) | Machinery List |
| Electricity Bill | Location Layout |
| Authorization Letter | Equipment List |
| QCI Adhaar Card | Process Flow Chart and Description |
| QCI Appointment Letter | NABL approved Calibration |
| QCI Degree Certificate | Product Specific Declaration as per clause no |
| Owner’s Pan Card | |
| Factory License |
The BIS certification process for Door closers, Hydraulically Regulated Door Closers 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.
BIS certification is crucial for several reasons:
Market Access: It shall be marked with the ISI mark for it is compulsory for any manufacturer who wants their Door closers, Hydraulically Regulated Door Closers to be sold in India. This means that without this certification, manufacturers will not be able to sell their products to the market.
Consumer Safety: Certification means that the products have to conform to given standards in order to prevent the consumer from using dangerous products.
Quality Assurance: The BIS certification process helps ensure the quality standards of the products as it covers quality control aspects of the products.
Regulatory Compliance: The BIS certification acts as an asset to manufacturers since it avails them of the legal standards that are accepted by the government hence saving them from legal troubles.
Brand Credibility: An ISI mark adds value to the business by providing the consumers confidence that they are dealing with products that meet the nation’s quality standards.
Environmental Considerations: The BIS in its regulations has put forward specific measures to restrict the use of some dangerous chemicals when producing products that have to do with environmental effects in the industry.
The government-approved fees for BIS certification of molded solid rubber soles and heels under IS 6315:1992 are as follows:
| Category | Fee (INR) |
|---|---|
| BIS Application Fees | 9,000 |
| BIS Marking Fees | Micro Scale - 9,200 |
| Small Scale - 23,000 | |

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 .
