Which type of test weight class is required for testing Class III commercial scales with a capacity of 500 lb?
Answer: Weights meeting NIST Class F or better tolerances
NIST Handbook 105-1 specifies that test weights used for Class III device verification must meet Class F tolerance requirements or better.
When a CWT encounters a scale that displays weight in a non-approved unit of measure for a given commodity transaction, the correct action is to:
Answer: Reject certification because unapproved units violate NIST HB 44 requirements
NIST HB 44 specifies which units of measure are approved for each type of commercial transaction; non-approved units are grounds for rejection.
During a calibration of a crane scale at height, the technician should ensure which safety measure is in place?
Answer: Anti-fall protection is worn and the swing radius below is barricaded
Working at elevation requires fall protection for the technician and barricading the swing radius below to protect ground-level personnel from falling objects.
What is the significance of the 'maintenance tolerance' versus the 'acceptance tolerance' in NIST HB 44?
Answer: Maintenance tolerance is more lenient and applies to devices already in service
Maintenance tolerances are twice as lenient as acceptance tolerances and apply to devices already in commercial service, while acceptance tolerances apply to new or repaired devices.
A CWT is testing a scale in a flour mill where combustible dust is present. Which safety requirement applies to all electrical equipment brought in?
Answer: Equipment must be rated for use in Class II, Division 1 or 2 hazardous locations
Combustible dust environments are classified as Class II hazardous locations under the NEC, requiring explosion-proof or dust-ignition-proof rated equipment.
Which procedure must a CWT follow before applying an 'Approved' seal to a device?
Answer: Verify the device passes all applicable tests under NIST HB 44 and complete required documentation
Certification seals may only be applied after the device has passed all required tests and all documentation has been completed per regulatory requirements.
A technician is calibrating a scale in a meat packing plant where floors may be slippery with animal fat. The most appropriate footwear is:
Answer: Slip-resistant safety footwear with waterproof construction
Slip-resistant, waterproof safety footwear is required in wet and greasy food processing environments to prevent slip-and-fall injuries.
