  1. According to NIST HB 44, which environmental condition is a scale owner responsible for maintaining to ensure proper device performance?

    Answer: Conditions within the device's specified operating environment as stated by the manufacturer

    The device owner is responsible for maintaining the scale within the environmental operating conditions (temperature, humidity, vibration) specified by the manufacturer.

  2. NIST HB 44 defines 'legal-for-trade' use as:

    Answer: Commercial transactions where the weight is used to determine price or quantity for sale

    Legal-for-trade refers to commercial weighing where the measured value directly determines the cost or quantity exchanged between buyer and seller.

  3. Under NIST HB 44, when testing a retail price-computing scale, the inspector should verify that the computed price:

    Answer: Does not exceed the mathematically correct price by more than one cent

    HB 44 limits price-computing errors so the customer is never charged more than one cent above the mathematically correct price based on unit price and net weight.

  4. A livestock scale with a 10,000 lb capacity and 5 lb divisions is tested with a 5,000 lb load. According to NIST HB 44, which test load placement must be included?

    Answer: Four corners and center of the platform

    Shift (off-center) testing at the four corners and center is required to verify that a livestock scale gives accurate results regardless of where the animal stands.

  5. According to NIST HB 44, the 'sealing' of a device after adjustment is intended to:

    Answer: Prevent unauthorized access to adjustable components that affect accuracy

    Official seals or security marks protect metrologically significant adjustments from unauthorized tampering after a weights and measures inspection.

  6. NIST HB 44 requires that weight indications on a scale be expressed in which unit system for commerce conducted in the United States?

    Answer: Either US customary or metric units, or both, as appropriate

    HB 44 permits weight to be expressed in US customary units, metric (SI) units, or both, depending on the application and customer requirements.

  7. Under NIST HB 44, what is the correct procedure if a weights and measures inspector discovers that an official seal has been broken on an in-service commercial scale?

    Answer: Record the broken seal, place the device out of service, and require it be retested before return to service

    A broken official seal indicates potential unauthorized adjustment; the device must be condemned and subjected to a complete re-inspection before returning to commercial service.
