Question

At which variation percent from average value, should the test be repeated?

(a) 4%

(b) 3%

(c) 2%

(d) 8%

I have been asked this question in an interview.

I want to ask this question from Tractor Testing in chapter Farm Tractor of Farm Machinery

Answer 1

Right option is (c) 2%

Best explanation: Test at maximum power test is done with the help of a suitable dynamometer. The maximum power quoted in the report should be the average of the readings taken during the two hours test. If the power variation exceeds 2% from average value, the test should be repeated. If the same condition persists in further tests, it should be recorded in the report.
