ASTM E1453-14

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: E1453 − 09 E1453 − 14
Standard Guide for
Storage of Magnetic Tape Media that Contains Analog or
1
Digital Radioscopic Data
This standard is issued under the fixed designation E1453; 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 guide may be used for the control and maintenance of recorded and unrecorded magnetic and optical media of analog
or digital electronic data from industrial radioscopy.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
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 and health practices and determine the applicability of regulatory
limitations prior to use. For specific precautionary statements, see Section 6.

3. Significance and Use
3.1 The provisions of this guide are intended to control and maintain the quality of recorded industrial electronic data from
radioscopy and unrecorded magnetic and optical media only, and are not intended to control the acceptability of the materials or
products examined. It is further intended that this guide be used as an adjunct to Guide E1000 and Practice E1255.
3.2 The necessity for applying specific control procedures such as those described in this guide is dependent to a certain extent,
on the degree to which the user adheres to good recording and storage practices as a matter of routine procedure.
4. Unrecorded Media Storage
4.1 Un-Opened Containers:
4.1.1 Storage Recommendations—Any media in containers sealed by the manufacturer and not opened should be stored as
shipped, whenever possible, to avoid container damage and possible media damage. Storage temperature should be 60° 6 20°F
(16 6 11°C), relative humidity range of 45 6 15 %, at a pressure range of 12.5 6 2.5 psi and a maximum magnetic field strength

of 50 Oe. The optimum storage conditions are 65°F (18°C) at 40 % relative humidity, 14.7 psi and a maximum magnetic field
strength of 30 Oe. Damaging stresses in the media can be produced by large temperature and humidity variations even if they
remain within the specified ranges. Specific media manufacturer’s recommendations should be consulted when large variations in
temperature or humidity, or both, are anticipated or experienced.
4.1.2 Higher or Lower Storage Conditions—When temperature exceeds 90°F (32°C) or humidity exceeds 90 %, or pressure
exceeds 15 psi, some unrecorded media should be used under normal existing conditions to test for degradation. If degradation
is found on these samples, subsequent sampling may be done on other media to avoid unnecessary scrap. If storage temperat
