GB/T 11885-2015Automatic rail-weighbridges (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 11885-1999 "Automatic Railway Track Scale." this standard compared with GB/T 11885-1999, the main technical changes are as follows.

--- The maximum permissible error measurement requirements change (see 4.5);

--- Refine the weighbridge installation requirements (see 5.19);

--- Increasing the specific requirements of the line and the scale housing (see 5.19.3 and 5.20);

--- Increasing the weighbridge software technical requirements (see 5.21);

--- An increase of some test requirements (see 6.2 6.6,6.10 ~ ~ 6.14,6.18);

--- Of test items have been classified (see 7.2);

--- Increased testing methods installed (see 7.3).

This standard uses redrafted Law Amendment uses OIMLR106-1.2011 "Automatic Railway Track Scale" international recommendations.

This standard R106-1.2011 technical differences and their reasons are as follows.

--- Increased 5.19.3 "line" and 5.19.4 "transition" on the specific requirements, improve the measurement performance track scale;

--- An increase of 5.20 "weighing room" at the request of track scale operation and maintenance more convenient;

--- 6.16 "Dynamic Weighing test" prepared in accordance with Test Method of testing wagons prepared to adapt our test methods;

--- An increase of 6.18 "long-term stability" to improve the performance measurement track scale;

--- 7.1 "type test" in the preparation of type approval and in accordance with the requirements of type evaluation, adaptation of the relevant provisions of China;

--- Remove R106-1. B "axis weighing track scale level correction utility" 2011 Appendix NA of railroad track scale technology development;

--- Increased in Chapter 2, normative references.

This standard made the following editorial changes.

--- Use the "standard" instead of "the present international recommendations." Please note that some of the content of this document may involve patents. Release mechanism of the present document does not assume responsibility for the identification of these patents.

1 Scope

This standard specifies automatic weighbridge (hereinafter referred to as "track scale") terms and definitions, measurement requirements, technical requirements, testing and inspection party Method, inspection rules and signs, packaging, transportation and storage.

This standard applies to standard gauge, to determine the quality of railway wagons by rail scale dynamic weighing mode (including axle weighing, truck weighing and vehicle weighing). Other gauge, weighing range and accuracy class rail scale may refer to the use of this standard; continuously tracks automatically track scale, rail pad Automatic sensor automatic sensor rail track scale and weighbridge may also refer to the use of this standard.
