Failure to comply can result in costly recalls, lost business opportunities, and compromised product safety.

The NIST Traceable Calibration of Weighing Instruments testing service is conducted in a controlled environment with precise temperature, humidity, and pressure conditions. The test equipment used includes:

Step-by-Step Testing Procedure

1. Sample preparation: Prepare the weighing instrument for testing by calibrating it to its maximum capacity.

2. Measurement: Measure the sample using the calibrated weighing instrument.

3. Data collection: Collect and record measurement data.

4. Analysis: Analyze the measurement data to determine accuracy.

Testing Parameters and Conditions

Calibration and Validation Procedures

The weighing instrument is calibrated using NIST-traceable weights before each measurement. The calibration process involves:

1. Zero adjustment

2. Span adjustment

3. Check of linearity

Quality Control Measures

To ensure accurate testing results, quality control measures are implemented throughout the testing process.

Data Collection and Recording Procedures

Measurement data is collected using digital means and recorded in a standardized format for easy analysis and reporting.

Testing Timeframes and Duration

The test duration typically ranges from 30 minutes to several hours depending on the type of weighing instrument being tested.

Sample Size Requirements and Statistical Considerations

A minimum sample size of five measurements is required to ensure statistical reliability.
