ASTM F2440-18

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: F2440 − 11 F2440 − 18 An American National Standard
Standard Specification for

Indoor Wall/Feature Padding
This standard is issued under the fixed designation F2440; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This specification covers wall padding and padding for other indoor structures. All padding constructions are included. The
intended use of this specification is for the qualification of construction designs and comparison of products.
NOTE 1—This specification was developed due to the numerous designs in existence and the need to provide a method to determine if a wall pad meets
a minimum level of protection.
NOTE 2—There is no equivalent ISO standard.
1.2 The values as stated in SI units are to be regarded as the standard. The values in parentheses are given for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use. See 7.1 for specific hazards statement.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
