Question:
Is it permissible on Chol Hamoed to have a garment tested for shaatnez? Does it make a difference why it was not done before Yom Tov?
Answer:
It should not be checked for Shatnez on Chol Hamoed, because it is a maaseh uman (professional type of work) and may not be done even for Yom Tov use.
