ASTM F571-87(2001)

1.1 This practice provides information for the installation of exit devices used in areas of security to achieve the greatest security possible without violating the requirements and spirit of NFPA 101.

1.2 Security of a high level is not always possible with these products but the use of certain types and functions of exit devices will afford a much higher degree of security than the use of other types and functions.

1.3 The values as stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

This practice is not meant to include products other than exit devices except to the extent that such products directly relate to the use of exit devices. When other products are described, the security attributes of the other products are described generally in the documents referenced in Section 2.
