Hello, Firstly thank you for such videos. I have a question. What is the main difference between ISO 3071: a method for determining the pH of the aqueous extract of textiles and AATCC 81: pH of water extract from wet processed textiles. Which method should we choose according to which request?

3071 is shaking method and applicable for European customers. AATCC 81 is boiling method and applicable for American customers.

Thank you for your kindly response. I want to ask one last question to make it clear to me. When we apply both methods to a fabric, the pH value is still the same, right? Thank you in advance for your reply.

0.1N Kcl is use in ISO-3071 PH as distilled water. Because Kcl stabilize the PH operator check PH most time repeatedly its PH constant. Instead PH perform with distilled water.
