As you can see, APPA 73 is the oldest of the three standards, having been published in 1973. ANSI/BIFMA X5.5-2013 and ANSI/BIFMA X5.5-2017 are more recent standards, and they incorporate some additional safety and performance requirements. However, all three standards are voluntary, and there is no legal requirement to comply with any of them.
The following table provides a more detailed comparison of the three standards:
| Feature | APPA 73 | ANSI/BIFMA X5.5-2013 | ANSI/BIFMA X5.5-2017 |
|---|---|---|---|
| Strength | Requires office furniture to be able to support a load of 200 pounds per square foot | Requires office furniture to be able to support a load of 250 pounds per square foot | Requires office furniture to be able to support a load of 300 pounds per square foot |
