Spec Note explains how to read the specs and certification standards behind mobile, computer, audio, and home appliance products.
These aren't hands-on reviews. We take manufacturer specs, national and agency certification standards, and official test data, and calculate what those numbers mean in daily use. What IP68 actually guarantees, how many years 80% after 800 cycles is: closing the gap between the rating sheet and real life is what this blog does.
About the Author
최정용Data analyst
I work as a data analyst. All three blogs are written the same way: I take the original rules and public data, do the calculations myself, and leave the assumptions and sources in the article. I don't write forecasts or recommendations, and I say so when something can't be confirmed. If you find a factual error, please let me know through the contact page. I'll check it, fix it, and note the correction in the article.
Principles of This Blog
- Not hands-on reviews.We cover only manufacturer specs, national and agency certification standards, and official test data. We never write as if we used a product we didn't.
- We calculate the numbers.We work out what a rating or spec means in everyday use and put it in a table, with the assumptions stated in the article.
- We cite sources.Specs and test results we quote link to the original. Figures we can't confirm don't go in.
