CWT Safety Procedures & Compliance 5

Question 1

When is it permissible to use a condemned weighing device in a commercial transaction?

Accepted Answer

Never; a condemned device must not be used until repaired and re-certified

Answer

A condemned device is legally prohibited from use in commerce until it has been repaired and successfully re-certified by an authorized inspector.

Question 2

What action should a CWT take if a client threatens or attempts to bribe them to pass a non-compliant scale?

Accepted Answer

Refuse, document the incident, and report it to the supervising authority

Answer

Bribery or coercion attempts must be refused and reported to the supervising authority to protect the integrity of the inspection process.

Question 3

A load cell replacement on a legally-for-trade scale requires which step before the scale is returned to service?

Accepted Answer

Full re-calibration and re-certification by an authorized W&M official or licensed technician

Answer

Replacing a load cell is a repair that affects metrological performance, requiring full re-calibration and official re-certification before return to commercial service.

Question 4

Which statement best describes the CWT's responsibility regarding a scale's 'zero-load reference' at the start of a test?

Accepted Answer

The technician must verify that the zero indication is within tolerance before proceeding with any load tests

Answer

Verifying zero-load reference within tolerance is a mandatory first step; an out-of-tolerance zero invalidates all subsequent load test readings.

Question 5

Under NTEP (National Type Evaluation Program), what does a Certificate of Conformance (CC) indicate?

Accepted Answer

The device type has been evaluated and found to meet NIST HB 44 requirements for use in legal-for-trade applications

Answer

An NTEP CC means the device type was evaluated against NIST HB 44 requirements and is approved for use as a legally-for-trade weighing device in the US.
