Hello group.
Looking for Standards Number that can explain the meaning of symbols used on drawings of Plastic Molded Parts.
Recently I found website, and drawing of molded part (attached below).
ISO 20457:2018 - Tolerances for plastic moulded parts - Information on the new standard
Some symbols specified on the drawing used only on drawings of molded parts and we did not meet it in the past.
Could anyone to advise Standards Numbers that can explain the meaning of these symbols?

- and the site you linked to (removed) provided training on the interpretation of the annotation.
Tell me and I forget. Teach me and I remember. Involve me and I learn.
