Foreword
Chapter 1~Chapter 3 and the content in 5.5.3.4d), 5.11.1.2.3, 5.12.1.2.1.5, 7.4.2, 7.4.3, I.1
and I.2 with "should" as well as Appendix E, Appendix F, Appendix H, Appendix J and
Appendix K of this standard are recommendatory, and the rest are compulsory. This standard is
drafted in accordance with the regulations of GB/T 1.1-2009. This standard replaces GB 16899-
1997 "Safety Rules for the Construction and Installation of Escalators and Moving Walks".
Compared with GB 16899-1997, this standard has the following main technical content changes
except editorial changes.
——Add partial terms (see Chapter 3);
——Adjust the list of significant hazards (see Chapter 4 and Appendix C of 1997 edition);
——Unify the requirements of all the escalators and moving walks including public-
transit type (partial requirements in GB 16899-1997 specially aim at public-transit escalators
and moving walks), and give recommendation with respect to public-transit escalators and
moving walks in Appendix H;
——Add specific evaluation methods for anti-slip properties of stair and pedal surface,
comb plate and floor plate surface (see 5.3.1, 5.7.1 and Appendix J);
——Add requirements for static load test of stair kickplate (see 5.3.3.2.2);
——Add stair and pedal torsion test requirements (see 5.3.3.3.1.2 and 5.3.3.3.2.2);
——Adjust the provisions for safety coefficient of driving element; the safety coefficient
of chain, driving belt and vee belt shall not be less than 5 is changed to that the safety coefficient
for static calculation of all the driving elements between service brake and stair, pedal or belt
driving device shall not be less than 5 (see 5.4.1.3.2, 12.3.2 of 1997 edition);
——Add the requirements for maximum deceleration of escalators and moving walks in
brake process (see 5.4.2.1.3.2, 5.4.2.1.3.4 and 5.4.2.2.2);
——Add principle requirements for nominal infinite fatigue life of stair chain (see 5.4.3.2);
——Add specific requirements for skirt deflector (see 5.5.3.4);
——Add specific test methods for evaluating the coefficient of sliding friction between
skirting and leather (dry or wet), PVC and rubber (see 5.5.3.4 and Appendix K);
——Modify the measures for reducing the personnel clamping risk between handrail
entrance and floor (see 5.6.4.2, 7.5.2 of 1997 edition);
——Modify the requirements for curvature radius of escalator transition from inclined
zone to upper and lower horizontal zone (see 5.7.2.2, 10.1.4 of 1997 edition);
——Add burning behaviour requirements of materials used for lower inner decking, lower
outer decking, truss, stair, pedal and guide rail system of escalators and moving walks (see 5.9);
——Add the requirements for partial monitoring devices and electrical safety devices (or
function) (see Table 6);
——Add relevant requirements for programmable electronic system in safety related
applications for escalators and moving walks (PESSRAE) (see 5.12.1.2.6 and D.6);
——Add specific requirements for static protection (see 5.11.7);
——Add the requirements for minimum nominal speed before the user reaching the
intersecting line of comb teeth and tread and for acceleration in the process transiting to normal
operation with respect to escalators or moving walks automatically started or accelerated due
to the user's access (see 5.12.2.1.2);
——Add the method to verify whether newly-designed product meets the safety
requirements and (or) protective measures specified in this standard (see Chapter 6);
——Add direction sign "Hold the handrail" and prohibition sign "Pushcart forbidden" (see
7.2.1.2.1 and Appendix G);
——Add the requirements for escalators and moving walks used for conveying shopping
cart and baggage car (see Appendix I); compared with EN 115-1.2008, this standard has made
the following adjustment in structure.
——Change 3.1.5a to 3.1.5, 3.1.5b to 3.1.6, 3.1.13a to 3.1.14, 3.1.13b to 3.1.15, and
correspondingly adjust other clauses of Chapter 3 so as to meet the requirements of GB/T 1.1-
2009;
——5.4.1.5 is divided into 5.4.1.5.1, 5.4.1.5.2 and 5.4.1.5.3 so as to add power supply and
control conditions of static elements used for AC or DC...
