I have 3 new updates for you this week, including a new blog post, measurement uncertainty training, and World Metrology Day 2025 celebration.

Here is what is covered in this week’s email:
1. (New) New Blog Post on Reproducibility
2. (This Week) Measurement Uncertainty Training Classes
3. (Tomorrow) World Metrology Day 2025

1. (New) Reproducibility: What is it and How to Calculate it
I just posted a new guide on our website blog – Reproducibility: What is it and How to Calculate it.
In this guide, I cover everything you need to know about measurement reproducibility, including beginner and advanced techniques. Here’s a list of what is included:
What is Reproducibility
Why Reproducibility is Important?
Reproducibility Testing Scheme
Reproducibility Conditions of Measurement
How to Calculate Reproducibility?
Reproducibility per ISO 5725-3
Reproducibility per ISO 5725-2
Reproducibility as a Range
Check it out. I include all step-by-step instructions with pictures for each evaluation method.
Personally, I recommend calculating reproducibility in accordance with ISO 5725-3
Here’s the link: Reproducibility: What is it and How to Calculate it.

2. (This Week) Measurement Uncertainty Training
This week, our Measurement Uncertainty for ISO/IEC 17025 training classes are on sale.
You have 3 training options.
Standard: Training lectures
Advanced: Training lectures with demonstrations
Premium: Training lectures with demonstrations and 1-on-1 consulting
Note: Advanced is not harder. It just includes additional videos to show you how to estimate uncertainty in Excel.
All of the classes are online and self-paced, so you can complete them on your own time. Plus, you can access the training videos for 6 months (even after you complete the training), and you will receive a training certificate.

3. (Tomorrow) World Metrology Day 2025 – 150th Anniversary
Tomorrow is World Metrology Day. This year celebrates the 150th anniversary of the Treaty of the Meter.
Some labs celebrate it. Others do not. Many labs do not even know anything about this. So, I am including information about it in today’s email to bring awareness.
