Foreword
Article 4 and Article 5 of this Standard are compulsory; the others are voluntary.
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB 13057-2003, The Strength of the Seats and Their
Anchorages of Passenger Vehicles.
Compared with GB 13057-2003, the major technical differences of this Standard are
as follows, in addition to editorial changes.
-- it changes the application scope of the standard (from “seats” to “passenger
seats”, and adds the content that “it also applies to the restraining barriers and
their vehicle anchorages installed in front of seats in such categories of
passenger vehicles”) (See Article 1);
-- it changes part of normative references (See Article 2);
-- it adds the terms and definitions of “forward-facing seat”, “anchorage” and
“restraining barrier” (See 3.2, 3.6, 3.14);
-- it deletes “requirements for static test” (See 4.1.2 of edition 2003) and “static test
for the seat” (See 5.1 of edition 2003).
This Standard was redrafted by modifying and adopting ECE R80, Uniform Provisions
Concerning the Approval of Seats of Large Passenger Vehicles and of These Vehicles
with Regard to the Strength of the Seats and Their Anchorages (Revision 1), English
version.
Compared with ECE R80 (Revision 1), this Standard has many adjustments in
structure. Annex C gives the table comparing the specific article numbers of this
Standard with those of ECE R80 (Revision 1).
Compared with ECE R80 (Revision 1), the major technical difference of this Standard
is that it specifies that each type of seats shall satisfy the requirements for dynamic
test. The articles concerning these technical differences are marked with vertical single
lines in the page margin. Annex D gives the list of technical differences and their
reasons.
This Standard was proposed by the Ministry of Industry and Information Technology of
the People’s Republic of China.
This Standard shall be under the jurisdiction of the National Technical Committee of
Auto Standardization (SAC/TC114).

Strength of the Seats and
Their Anchorage of Passenger Vehicles
1 Application Scope
This Standard specified the requirements and test methods for the strength of the seats
and their anchorage of passenger vehicles.
This Standard applies to forward-facing passenger seats in vehicles of class II, III and
B, categories M2 and M3, as well as the anchorage of all passenger seats of such
categories of passenger vehicles and the installation of their seats. It also applies to
