CST State Weights & Measures Laws 5

Question 1

A state statute provides that 'all weights and measures used commercially shall be in terms of the system of measurement defined by the International System of Units (SI) or the US customary system.' What does this primarily regulate?

Accepted Answer

The units of measurement that may legally appear on commercial transactions and packages

Answer

This type of provision controls which units of measurement (pounds, kilograms, ounces, etc.) are legally recognized for commercial transactions and package labeling.

Question 2

Under most state weights and measures laws, what is required before a scale technician may remove an official rejection tag from a device?

Accepted Answer

The device must be repaired and re-inspected by a weights and measures official, who then removes the tag

Answer

Only an authorized weights and measures official may remove an official rejection (condemnation) tag after verifying through re-inspection that the device has been properly repaired and now meets standards.

Question 3

State weights and measures laws typically define 'short weight' as a situation where the actual quantity delivered is:

Accepted Answer

Less than the quantity represented on the label or stated in the transaction

Answer

Short weight occurs when a customer receives less product by weight than was advertised, labeled, or agreed upon in the transaction.

Question 4

A state law requires that vehicle scales at public weigh stations be tested at least annually. Which test weight method is typically specified for large-capacity vehicle scales?

Accepted Answer

Calibrated test vehicles or test cars with known load

Answer

Vehicle scales are typically tested using calibrated test cars or trucks with known, certified loads because individual NIST-class weights cannot practically span the full capacity of a vehicle scale.

Question 5

A state inspector samples 25 packages of ground beef at a grocery store and finds the average net weight is accurate, but 6 individual packages are underweight. Under state law using the NIST Handbook 133 sampling approach, what is the likely finding?

Accepted Answer

The lot fails if the number of unreasonable minus packages exceeds the allowable maximum for the sample size

Answer

NIST Handbook 133 uses statistical sampling where both the average and the number of 'unreasonable minus' packages must be within limits — exceeding the allowable count of underweight packages can cause a lot to fail even if the average is acceptable.
