---Modified the standard name (see cover, cover of 2004 edition);

---The definition of rubber deceleration hill has been added (see 3.1);

---Modified the composition (see 4.1, 3.1.1 of the 2004 edition);

---Modified the general requirements (see 4.2, 3.1.2 of the 2004 edition);

--- Deleted retroreflective performance (see 3.4 in 2004 edition);

--- Increased density performance (see 4.4.4);

--- Increased chromaticity performance (see 4.5);

---Modified the pressure resistance test method (see 5.4, 4.2 of the 2004 edition);

--- Deleted the retroreflective performance test method (see 2004 version 4.4);

---Added chromaticity performance test method (see 5.6);

---Added settings (see Chapter 6).
