What is the acceptable scale indication range for a test load of 15,000 lb on a 60,000 x 10 lb axle load scale?

To determine the acceptable scale indication range for a test load of 15,000 lb on a 60,000 x 10 lb axle load scale, one must consider the tolerances allowed for such measurements.

For a scale indicating 10 lb increments, the acceptable tolerance typically ranges from ±2% of the test load. Two percent of 15,000 lb is 300 lb. This means the scale should indicate within a range calculated by subtracting and adding 300 lb from the target load of 15,000 lb.

Calculating this, you get:

• Lower limit: 15,000 lb - 300 lb = 14,700 lb

• Upper limit: 15,000 lb + 300 lb = 15,300 lb

Now examining the ranges provided:

• The range of 14,970 - 15,030 lb offers a much tighter tolerance of only ±30 lb from the actual 15,000 lb which falls within the ±2% limit.

• This range directly aligns with the acceptable indication based on the specifications given for accuracy in such scales, demonstrating a reliable result close to the test load.

In context, the other ranges present wider or narrower tolerances, moving outside of the standard
