Updated on June 19, 2025 02:53:19 PM

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.

Understanding IS 14912:2001

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.

Performance Requirements and Test Methods

IS 14912:2001 lays down various performance standards that the concealed type hydraulically regulated door closers must comply to:

Closing Time: The door closer should be one that can allow for an adjustable closing time that can take anywhere from 0.5 to 2 minutes.

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.

Testing Methods

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.
