Hydraulically regulated concealed type door closers are extremely important to maintain proper closure and safety of doors in many applications, including homes, offices, and other related facilities. In India, the Bureau of Indian Standards (BIS) has established IS 14912:2001 to prescribe the characteristics and standard of performance for these crucial apparatus. This standard guarantees that Concealed door closers not only perform efficiently but are also safe and of high quality.
IS 14912:2001 includes essential characteristics like the variable closing time, working temperature range, and structural endurance test to make sure that these door closers can be efficient in daily use. According to this standard, manufacturers arrive at reliable products that provide the best experience and security to customers. Secondly, BIS certification even guarantees consumers the quality and reliability of the specific door closers they select.
This blog will explore the various facets of IS 14912:2001 testing procedure for architectural hardware products, performance characteristics, test methods, and test procedures for obtaining BIS certification, and how BIS certification can contribute to the improvement of the standard of architectural hardware in India.
IS 14912:2001 is the Indian Standard set under the BIS that sets the standards for concealed-type hydraulically regulated door closers. These door closers are designed to be installed inside the panel of the door, giving it a stylish closure while giving it its closure functionality. This standard concerns only the doors installed on the ceiling in vertical hinge type heavy doors open on one side and with a mass of no more than 80 kg.
The primary purpose of IS 14912:2001 is to guarantee that these door closers provide dependability in different environmental states and are safe. Requirements and specifications include characteristics like the closing time that should be adjustable from 5 to 20 seconds by means of regulating screws, while the hydraulic oil operating temperature range should be within -10°C 50°C.
By adhering to IS 14912:2001, It shall be possible for manufacturers to offer door closers that meet performance standards in equal measure to the general users capable of delivering improved reliability and efficiency. This standard has a very important role in the protection of well-being and efficiency in the design and construction of buildings.
IS 14912:2001 lays down various performance standards that the concealed type hydraulically regulated door closers must comply to:
Temperature Range: Hydraulic oil used in the closer has to perform needed functions at temperatures from -10 to 50°C without requiring anything but rotating the regulating screw.
Endurance: The utilized door closer must withstand durability and reliability tests that must entail at least fifty thousand cycles.
Surface Quality: It should not have any roughness on the surface of the door closer like crack, dent, or burr in order to advance the beauty of the door closer and its efficiency.
To verify compliance with these performance requirements, IS 14912:2001 states that certain test methods are appropriate for determining the quality of the door closers and how well the door closers are designed to perform.
The testing methods outlined in IS 14912:2001 are important in ascertaining if concealed-type hydraulically regulated door closers have the required performance. Key testing methods include:
Closing Time Test: This test aims at assessing the time taken by the door from being fully open to its total shading, within the range of 5 to 20 seconds.
Temperature Performance Test: To test the functionality of the hydraulic oil in extreme temperatures the medium is exposed to different temperatures ranging between -10°C and 50°C.
Endurance Testing: Door closers are tested for their endurance and consistency by cycles of opening and closing (at least 50,000).
Visual Inspection: First, the exterior contour of the work surface is reviewed in order to identify any surface condition that can be negative to performance standards or the aesthetics of the end product.
Such testing methods are conducted in accredited laboratories with adequate equipment to ensure quality results are obtained.
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 14912:2001.
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, concealed type (hydraulically regulated) with IS 14912:2001. The standard specifies several key labeling requirements:
What Should Be on the Labels
Each article of Door closers, concealed type (hydraulically regulated) must be marked with the following information:
Manufacturer's Name or Logo: This shows who made the Door closers, concealed type (hydraulically regulated).
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:

The BIS certification process for Door closers, concealed type (hydraulically regulated) 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, concealed type (hydraulically regulated) 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.
