Key Components of ISO 16063 Calibration Methods

Each part of the ISO 16063 standard addresses a specific calibration need or methodology. Knowing which component applies to your operation helps ensure you're using the right calibration strategy.

Here are the key sections you should be aware of—and how they work in real-world scenarios.

1. General Terms and Definitions (ISO 16063-1:1998):

This foundational part defines standard terminology used throughout all other ISO 16063 parts. It helps eliminate confusion between technicians, engineers, labs, and suppliers, especially when collaborating across industries or countries.

Standardised terms improve internal training, prevent misinterpretation during audits, and support clear documentation in calibration certificates.

2. Primary Vibration Calibration by Laser Interferometry (ISO 16063-11):

This method is the gold standard for primary calibration. It uses laser interferometry to measure vibration amplitude and frequency with the highest level of accuracy.

Typically used in national metrology institutes or high-end labs, this part ensures traceability to international measurement standards.

3. Secondary Calibration by Comparison (ISO 16063-21):

Most businesses will use this method. It compares the transducer under test (DUT) to a reference standard accelerometer in controlled conditions.

It’s practical, cost-effective, and widely applicable across industries from automotive to aerospace and consumer electronics.

4. Calibration Using Shock Excitation (ISO 16063-22):

If your application deals with shock forces (e.g., crash testing, packaging impact, aerospace G-loads), this method outlines how to calibrate sensors for those high-intensity, short-duration events.

It’s essential for ensuring accuracy in environments where dynamic shock loads can occur unexpectedly.

5. Calibration by Laser Doppler Vibrometer (ISO 16063-41 and ISO 16063-45):

These parts introduce advanced non-contact methods using LDVs (Laser Doppler Vibrometers). They’re ideal for fragile or small sensors where physical contact could affect measurement accuracy.

ISO 16063-45:2017, in particular, enables calibration in a wide frequency range, making it a key tool for high-frequency applications such as electric motor testing or ultrasonic diagnostics.

6. Transverse Vibration Sensitivity Testing (ISO 16063-31):

This part checks if your sensor responds accurately to vibrations in unintended directions. It’s often overlooked but crucial for environments with multi-axis movement.

For example, in robotics or 3D manufacturing equipment, improper sensitivity could lead to distorted readings.

7. Mounting Considerations (ISO 16063-21 and Annexes):

Mounting conditions significantly affect transducer performance. These parts give clear guidance on how to mount sensors during calibration to avoid measurement drift.

Even something as small as using the wrong screw torque or adhesive pad can alter the results.

Practical Checklist for Implementing ISO 16063 Calibration Methods

Before you jump into calibration, it’s smart to check your readiness. This checklist ensures you have the right tools, training, and procedures in place.

Use it to assess your setup and close any gaps before applying ISO 16063 methods.

• Have you reviewed the specific parts of ISO 16063?

Identify the correct section (e.g., ISO 16063-1, ISO 16063-45) based on your type of transducer.

• Have you assessed the equipment required for calibration?

Do you have access to the necessary calibration tools (e.g., Laser Doppler Vibrometer, reference transducers)? Are your calibration tools certified and compliant with ISO standards?

• Have you ensured that all relevant staff are trained?

Have your technicians undergone training for the calibration methods outlined in ISO 16063? Are they familiar with the specific calibration procedure for the type of transducer used in your operations?

• Have you checked the transducer's condition before calibration?

Are the transducers you are calibrating free from damage and operationally sound? Are the sensors or equipment clean and properly maintained?

• Have you implemented the correct calibration method?

Are you following the correct ISO 16063 method, whether it’s comparison to a reference transducer or a dynamic calibration approach? Are the measurement conditions controlled to ensure accuracy?

• Are you documenting the calibration results?

Think about the results of your calibration process, thoroughly documented, including all adjustments and final readings? Do you have a clear record of the calibration certificates for future reference or audits?

• Have you verified the accuracy of the calibration?

Have you cross-checked the results against a reference transducer or through another verification method? Are your calibration results reproducible and consistent?

• Do you have a regular calibration schedule in place?

Is there a routine calibration schedule for your vibration and shock transducers? Are the intervals based on transducer usage, industry standards, and operational needs?

Steps to Achieve Accurate Calibration Using ISO 16063

Once you’re ready, it’s time to apply the process. These steps help ensure your calibration is technically sound and fully ISO-compliant.

Following this approach minimises risk and strengthens measurement reliability.

Step 1. Understand the Calibration Requirements

Start by identifying what kind of transducer you’re calibrating: accelerometer, velocity sensor, or displacement sensor? Is it exposed to vibration, shock, or both?

Review the full ISO 16063 series and note which parts apply. This decision depends on sensor type, operating range, and your industry (e.g., aviation vs. packaging).

Step 2. Choose the Right Calibration Method

ISO 16063 provides flexibility, but not every method fits every scenario.

• Use comparison methods (ISO 16063-21) for general-purpose industrial calibration.
• Use shock calibration (ISO 16063-22) if your product is exposed to impacts.
• Use laser-based methods (ISO 16063-45) when extreme precision or non-contact setup is required.
• Choose dynamic calibration if your transducer must operate during motion or in unpredictable environments.
  

Picking the wrong method can result in poor repeatability or invalid data, especially in safety-critical systems like aircraft or bridges.

Step 3. Prepare the Calibration Setup

Set up a controlled environment, usually a lab-grade vibration platform or shock table. Use ISO-compliant mounting procedures, make sure environmental conditions (humidity, temperature) are within spec, and verify that your reference equipment is recently calibrated itself.

Poor setup is the most common source of calibration drift or failed audits.

Step 4. Perform the Calibration According to ISO Procedure

Execute the steps defined in the relevant ISO 16063 section.

• Record baseline data.
• Run the test frequency or shock pulse.
• Measure and log outputs.
• Compare with reference data.
• Repeat the process as needed to confirm consistency.

If you use a software-based automation system, ensure it logs raw data and generates traceable certificates.

Step 5. Document and Verify Results

Your calibration results must be clear, reproducible, and audit-ready. Include details such as the equipment used, the technician’s name, date, conditions, raw readings, corrections applied, and final output values.

If you're part of a certified quality system (like ISO 9001 or ISO/IEC 17025), this documentation becomes critical for both internal and external audits.

Step 6. Review and Schedule Future Calibrations

Use the results to assess sensor health and set the next due date. High-use or high-vibration environments may require more frequent calibration intervals.

Logging trends over time can also help identify sensors nearing the end of their service life, before they fail in the field.
