IS 13362:1992 Part 2 is the Indian Standard (BIS) for methods of test for doors and window assemblies - part 2: air permeability. This standard specifies the laboratory method for determining the air permeability of door and window assemblies when subjected to positive or negative air pressure. It details the test apparatus, procedure, and calculation method to quantify air leakage, which is a key performance indicator for energy efficiency and weather-tightness of building envelopes.
Specifies a method for determining the air permeability of doors and window assemblies.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
Practical Notes
! The maximum test pressure for a project is derived from the design wind pressure calculated as per IS 875 (Part 3), considering building location, height, and topography.
! This part (Part 4) only covers resistance to static pressure. Other performance aspects like air leakage and water penetration are covered in other parts of the IS 13362 series.
! Careful sealing of the test specimen in the chamber is critical to avoid leakage and ensure accurate pressure application on the assembly's face.

Key Differences
≠IS 13362-1 is a unified method for both doors and windows, whereas European standards are split into EN 12046-1 (Windows) and EN 12046-2 (Doors).
≠The IS code is purely a test method and does not provide performance classes or acceptance criteria. In contrast, standards like EN 12217 provide a detailed classification system (e.g., Class 1 to 4) based on measured forces.
≠International standards like EN 12046 specify the use of a 'force gauge with an accuracy of ±2% of the measured value', which is more precise than the 'spring balance or equivalent' suggested in the IS code.
≠The ASTM E2068 standard is specifically for sliding windows and doors, while IS 13362-1 covers all types of operation (sliding, swinging, etc.) under one general procedure.
Key Similarities
≈All standards are based on the same fundamental principle of applying force at the normal operating point (e.g., handle) and measuring the force required.
≈Both IS and international counterparts specify measuring the forces to initiate motion, sustain motion, and operate locking/latching mechanisms.
≈The general test setup, requiring the specimen to be installed as it would be in use and the force applied in the direction of operation, is consistent across all standards.
≈All standards use Newtons (N) as the primary unit for force measurement, ensuring a common basis for comparison.

Frequently Asked Questions4
What is the purpose of this test?+
To determine the structural performance and deflection of a door or window assembly under a specified static wind pressure (Clause 4).
Does this standard specify the passing criteria for wind pressure?+
No, it is a 'method of test'. The passing criteria (maximum allowable deflection or damage) are typically specified by the specifier or relevant building regulations, based on the performance required.
How are positive and negative pressures tested?+
The test is conducted by first applying positive pressure (pushing inwards), releasing it, and then applying negative pressure (pulling outwards) on the assembly (Clause 7.2).
Is air leakage measured in this test?+
No. This test is for wind resistance only. Air leakage testing is covered in IS 13362 (Part 2).
