CST NIST Handbook 44 Standards 3

Question 1

NIST HB 44 requires that vehicle scales have a minimum division (d) value of no greater than:

Accepted Answer

10 lb

Answer

For vehicle scales used in commercial transactions, NIST HB 44 specifies that the value of the scale division (d) shall not exceed 20 lb, with 10 lb being the common requirement for accuracy class purposes.

Question 2

Under NIST HB 44, a 'tare' is best defined as:

Accepted Answer

A weight subtracted from the gross weight to obtain net weight

Answer

Tare is a weight (such as a container or vehicle) that is subtracted from the gross weight to yield the net weight of the commodity being sold.

Question 3

According to NIST HB 44, which statement is correct regarding automatic zero-tracking (AZT)?

Accepted Answer

AZT is limited in rate and range to prevent it from masking real load changes

Answer

HB 44 limits automatic zero-tracking rate and range so it cannot compensate for actual weight being placed on the scale, ensuring measurement integrity.

Question 4

Which section of NIST HB 44 covers 'Scales' specifically, including retail, vehicle, and crane scales?

Accepted Answer

Section 2.20 and its subsections

Answer

NIST HB 44 Section 2.20 and its lettered subsections (2.20.1 through 2.20.8) address scales including general code, retail, vehicle, livestock, and crane scales.

Question 5

A scale has a capacity of 1,000 lb with a division of 0.5 lb. How many scale divisions does this device have?

Accepted Answer

2,000

Answer

The number of scale divisions equals capacity divided by division size: 1,000 ÷ 0.5 = 2,000 divisions.
