What is the specified seat height for an office chair under this standard?

The seat height (H1) must be between 420 mm and 500 mm, as per Table 1.

What is the static load the seat must withstand?

The seat must withstand a static load of 1360 N applied vertically for 1 minute without breaking, as per the test described in Clause 7.3.

What are the material requirements for the plastic?

The standard specifies that the plastic used should be virgin polypropylene conforming to IS 7328 or other engineering plastics with comparable properties (Clause 4.1).

How is the chair's stability tested?

Forward and sideway stability are tested by applying specified forces (e.g., 200 N for forward stability) at the edge of the seat to check if the chair tips over (Clause 7.2).

This standard specifies the material, dimensional, and performance requirements for fixed-base plastic chairs intended for general office use. It covers chairs with and without arms (Type B and Type A respectively) and outlines the testing procedures to ensure their stability, strength, and durability.

Practical Notes

This standard is for non-revolving, fixed-base chairs only. Revolving chairs are covered by other standards.

Performance testing, such as static load and stability tests, is critical for compliance and user safety. These tests are detailed in IS 5416.

The standard distinguishes between Type A (without arms) and Type B (with arms) chairs, which have different dimensional requirements, particularly the overall width and width between arms.
