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

    Answer: 10 lb

    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.

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

    Answer: A weight subtracted from the gross weight to obtain net weight

    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.

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

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

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

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

    Answer: Section 2.20 and its subsections

    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.

  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?

    Answer: 2,000

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

  6. Under NIST HB 44, the 'repeatability test' requires that:

    Answer: The same load is applied and removed multiple times to check consistency of readings

    The repeatability test involves applying and removing the same test load multiple times to verify that the scale consistently returns the same reading.

  7. NIST HB 44 specifies that a 'certificate of conformance' or type approval is required before a new device model can be:

    Answer: Placed into commercial service in a jurisdiction adopting HB 44

    Type approval (NTEP Certificate of Conformance) is required before a device model may be legally used for commercial weighing transactions in jurisdictions that adopt NIST HB 44.
