Joining ASTM International and one or more technical committees can be done online at: http://www.astm.org/MEMBERSHIP/MemTypes.htm. Your annual membership fee of $75 comes with a complimentary volume of the Book of Standards in print or an Online Volume (you access the standards via the internet). The Online Volume offers the advantage of access to standards revised during the time of the membership/subscription. Online Volumes also provide access to historical and redline standards.
If you are a current member, you can easily join additional committees and subcommittees from the ASTM website. Simply log in to your My ASTM account and click on the "Join Additional Committees" tab on the left side of the screen.
Simply log in to your My ASTM account, and click on the "Invite a Colleague" tab on the left side of the screen.
Your username will always be either your membership number or email address (either can be used). If you have forgotten your password, use the Forgot Password link located on the login page.
From www.astm.org, select "Sign In" at the top right of the page. Use your member number or email address as USER ID, and "ASTM" in all capital letters as PASSWORD the first time you log in. You will immediately be prompted to change your password. Select "My Committees" to view information about any committee you are a member of.
