IS 13089:1991 is the Indian Standard (BIS) for furniture - storage units - determination of stability. This standard specifies the test methods for determining the stability of all types of free-standing storage units for domestic and non-domestic use. It provides procedures for applying vertical and horizontal forces to simulate use, ensuring the furniture does not tip over when unloaded, loaded, or with doors and drawers open.

Practical Notes
! The tests simulate worst-case scenarios, such as a child pulling on an open drawer or all doors being open at once.
! Ensure the test surface is perfectly horizontal and rigid to get accurate results, as any slope can significantly affect stability.
! This standard is crucial for manufacturers to ensure product safety and prevent accidents related to furniture tipping over.

Key Differences
≠Modern standards like ASTM F2057 have a strong focus on preventing child-related tip-over accidents, using loads simulating a child's weight (e.g., 60 lbs / 27.2 kg). IS 13089 uses more general force values not specifically linked to child anthropometry.
≠ASTM F2057 mandates testing on both a hard surface and simulated carpet, acknowledging that stability is reduced on soft flooring. IS 13089 specifies testing only on a single rigid, horizontal platform.
≠IS 13089 specifies loads in kilograms (kg) or kg-force, an older convention. All modern international standards exclusively use Newtons (N) for force measurement, which is the SI unit.
≠For some key tests, such as the ASTM F2057 stability test, all drawers are opened simultaneously to create a worst-case scenario. IS 13089 typically specifies opening only one drawer at a time for its tests.
≠Modern standards like EN 14749 and ISO 7171 clearly differentiate requirements for units intended to be attached to a wall versus free-standing units, including specific warnings and instructions. IS 13089 is less explicit, primarily addressing free-standing stability.
Key Similarities
≈All standards share the fundamental objective of testing a storage unit's resistance to tipping over when subjected to forces simulating foreseeable use and misuse.
≈A core test procedure common to all standards is to open drawers to their stop and/or doors to 90 degrees before applying loads, simulating a vulnerable, in-use state.
≈All standards include a test where a vertical force is applied to the front edge of an extended drawer or open door to simulate weight from leaning or climbing.
≈All standards specify a test involving the application of a horizontal force to the unit to simulate pushing or pulling, which could cause it to tip.

Frequently Asked Questions5

What is the purpose of this standard?+
To provide a uniform method for determining the stability of storage units to prevent them from tipping over, ensuring user safety.
Does this test apply to wall-mounted units?+
No, this standard is specifically for free-standing storage units (Clause 1).
What force is used to test stability with a door open?+
A vertical downward force of 100 N is applied at the point on the edge of the door or flap furthest from the unit's pivot axis (Clause 6.2.2).
How is a unit 'loaded' for the test?+
Each drawer and shelf is loaded with masses equivalent to 0.5 kg per cubic decimetre of its storage volume (Clause 6.3.1).
What is the pass/fail criterion?+
The unit shall not overturn during any of the specified tests (Clause 6).
