specified in 5.8, the retro-reflective area of the retro-reflector shall have no obvious cracks,
deformation and other defects; the retro-reflective sheeting and fluorescent materials shall have
no wrinkles, bubbles, peeling and other defects; the protective devices for the triangles shall be
easy to open and not stick or tear. After the high-temperature resistance test, the retro-reflector
shall be tested for luminosity properties in accordance with the method specified in 5.3.1, and
shall comply with the requirements of 4.1.3; other retro-reflective devices shall be re-tested for
luminosity properties in accordance with the method specified in 5.3.5; the coefficient of
luminous intensity of the triangles shall not be less than 80% of the value specified in Table 4;
other retro-reflective devices shall comply with the requirements of 4.1.3.

After carrying out the salt spray corrosion test in accordance with the method specified in 5.9,
the retro-reflective device (except the triangles) shall have no trace of corrosion. The luminosity
properties re-tested in accordance with the method specified in 5.3.5 shall comply with the
requirements of 4.1.3. The nighttime color of the retro-reflector re-tested in accordance with
the method specified in 5.4.1 shall comply with the requirements of 4.1.4.1, and the daytime
color of other retro-reflectors re-tested in accordance with the method specified in 5.4.2 shall
comply with the requirements of 4.1.4.2; the retro-reflective sheeting and fluorescent materials
shall be free of softening, wrinkles, bubbles, discoloration and other defects, and the 180 peel
