In order to receive copies of committee working documents you need to be a member of your National Technical Advisory Group (TAG) who will register you on ISO Livelink (isotc.iso.org). If you are a USA resident or your company is registered in the USA you can join the U.S. TAG. The membership fee is $6,000 per year.
* If you join mid-year your membership fee will be prorated. This is setup specifically for new members or members who have not participated or voted for at least 6 months(see eccma.org/ustag/)
