--- Cancel the inclined beam shelf staircase (see 4.1, JG 3002.2-1992 4.1 and 4.3);
--- Increased common specifications for evacuation slab stairs in residential buildings (see 4.2);
---Adjusted the method of stair marking (see 4.3);
--- Adjusted the requirements for the appearance quality and dimensional deviation of prefabricated stairs (see 6.1, 6.2);
--- Increased the requirements for the strength of precast stair concrete (see 6.3);
--- Increased the thickness of the concrete protective layer for prefabricated stair reinforcement (see 6.4);
--- Increased performance inspection requirements for prefabricated stair structures (see 6.5);
--- Increased the relevant provisions of prefabricated staircase type inspection (see 8.2);
--- Increased the requirements for the certification of prefabricated staircase products (see Chapter 10);
--- Added test method for prefabricated stair structure performance (see Appendix A).
