GB/T 15833-2007Test methods for forestry wheeled tractors and crawler tractors (English PDF)

Foreword

This standard is GB/T 15833-1995 "forestry wheeled and crawler tractors test methods" revised, and this standard GB/T 15833-1995 has compared the main following changes.

--- Parameter measurement accuracy, to allow parameter measurement error;

4.2.4 original "place quality 65kg weight in the driver's seat instead of in the middle" to "middle of the driver's seat Place quality 75kg ± 5kg of weight in place of the driver ";

6.3.1.4 Equation (3) in the "0 state", "state 1" to "N0", "N1", "when 50m long distance" to "test area" wheels " Average

7.1.1 blank line conversion time of the original standard "prescribed by a blank line time conversion 1h 4h time" to "empty accordance with the provisions 5h Line time conversion 1h time ", and the unity of the domestic agriculture and forestry tractor industry standards;

7.4.1.1 original "engine test bed" to "PTO power (or engine bench) test";

7.4.2.1 original "test prototype units for each model number 2" to "experimental prototype engine power greater than the number of units of 18kW Tractors, two each model, and the remaining three ";

7.4.2.2 original "tractors on the job each cumulative operation time 1200h" to "a variety of operations Cumulative tractor For the time 1500h (2 × 750h or 3 × 500h) ";

7.4.2.4 Add "skidding tractor carrying amount shall not be less than 80% of the rated carrying amount" requirement;

--- 7.4.2.8 "tractor fault definition, classification and judgment rule, shall implement the relevant provisions of the standard" to "tractor fault Definition, classification and judgment rule shall JB/T 51082 relevant provisions "line 4" (according to the time when first appeared dollars). " To "(when the time counted by the first time)";

--- Given the current industry specific conditions, the 7.4.3 "Final inspection and precision measurement" to be selected as entries;

1 Scope

GB/T 15833-2007 is the Chinese national standard on test methods for forestry wheeled tractors and crawler tractors, in the field of agriculture. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 25 June 2007 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 November 2007. Classification: ICS 65.060.10, CCS T61. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the general requirements for wheeled and crawler tractors forestry experiments, the whole parameters measured, common pilot projects, through test, Forest use test, equipment test. This standard applies to forestry wheeled and crawler tractors (hereinafter referred to as tractors).
