Scope

This standard is intended to provide manufacturers, specifiers, and users with a common basis for evaluating the safety, durability, and structural adequacy of business and institutional lounge and public seating.

Lounge and public seating is normally used in indoor public spaces such as waiting, reception, or gathering areas.  Lounge and public seating includes products with single seat units, units with multiple seating positions within one unit or ganged seating units.  Lounge and public seating may be restrained from moving by attaching to the building structure or freestanding.  Lounge and public seating products are generally not adjustable for personal use. This standard does not address general-purpose or task-oriented office chairs, or seating used for stadiums, auditoriums, lecture rooms, airports/train stations and similar high-use public seating areas.

Where a product may be covered by more than one ANSI/BIFMA standard, the manufacturer shall determine which standard provides most appropriate test conditions.  Where a product is intended for use outside of the commercial office and related institutional environments, it is the responsibility of the user of this standard to determine if it is suitable for use in such evaluations.   

This standard specifies tests and acceptance levels to help ensure reasonable safety and performance independent of construction materials, manufacturing processes, mechanical designs, or aesthetic designs. This standard does not address flammability, surface material durability, cushioning materials, product emissions, or ergonomic considerations.

The acceptance levels herein are based on the actual field and test experience of BIFMA International members.  Where appropriate, the CAESAR anthropometric database (2002 report), which indicates the 95th percentile male weighs 253 pounds, was used in the development of the tests.  The tests were developed with an estimated product life of ten years based on continuous single-shift usage.  Product life will be affected by user size/weight, product use, care and maintenance, environment, and other factors, and, as such, product compliance to this standard does not necessarily guarantee a ten-year product life.  Products may perform longer than 10 years with appropriate use and care. This standard may not apply to seating for persons in medically compromised conditions that are often found in certain health care environments, such as physical therapy and weight loss clinics.  These environments may require specific product designs that may not be adequately covered by the requirements of this standard.

The tests in this standard are intended to assess the performance of new products only.  They are not intended to assess a product that has been in use.

ISO 17025 requirements for reporting uncertainty do not apply when determining conformance to this standard.
