What is the primary purpose of this standard?

To provide a uniform method for testing the strength and durability of settees and benches, ensuring they are safe for their intended use.

Does this standard cover stability against tipping over?

No, this is Part 1 which covers strength. Stability tests are specified in IS 12674 (Part 2).

What is a typical seat durability test?

It involves applying a specified load (e.g., 1000 N for heavy use) repeatedly to the seat for a high number of cycles (e.g., 100,000) to simulate long-term use and check for fatigue failure (Clause 6).

Is this standard applicable to office chairs?

No, this standard is for settees and benches. Office chairs are typically tested as per IS 5416 and the IS 14944 series.

This standard specifies the test methods for evaluating the structural strength and durability of settees and benches. It includes procedures for static and fatigue testing of key components like seats, backs, and armrests to ensure safety and performance under various use conditions.

Methods of test for strength and stability of settees and benches, Part 1: Strength

Quick Reference Values

Seat static load (heavy contract use)1600 N

Back static load (heavy contract use)560 N

Arm downward static load (heavy contract use)900 N

Seat durability test load (heavy contract use)1000 N

Seat durability test cycles (heavy contract use)100,000 cycles

Leg forward static load330 N

Practical Notes

Crucial for manufacturers to certify products for different markets (e.g., domestic, contract/public use), which have different load requirements.

Test results are pass/fail based on whether the item shows any fractures, loosening of joints, or structural damage after the test.

Correct positioning of loading pads as specified in the standard is essential for accurate and repeatable test outcomes.
