This classification is meant to be a guide for the selection of a vault.

This classification is intended to assist users in availing themselves of various prefabricated and generically constructed products, while maintaining continuity in the selected intrusion-resistance level.

This classification is not meant to recommend or prefer the use of any single product or any type level, or its application.

1.1 This classification is for the use and guidance of those who purchase, design, construct, install, approve, or modify storage vault enclosures, intended for the protection of assets against loss due to forced entry.

1.2 This classification is a systematic arrangement of constructed products, based on similar intrusion resistance characteristics, as derived from available test data.

1.3 This classification does not address fire resistivity.

1.4 This classification does not address the methods of interfacing vault components.

1.5 Nothing in this classification is intended to prevent the use of systems, methods, or devices that provide a level of intrusion resistance equivalent to that prescribed herein.

1.5.1 Any system, method, or device different from that detailed herein may be examined, in accordance with the intent of this standard, and if found equivalent, may be included.

1.6 Nothing in this classification shall be construed to prohibit better or safer conditions than the requirements specified herein.

1.7 Each standard designation cited shall be meant to be the edition in effect on the date this classification was published.

1.8 A rationale is given in . For more information on the construction of bank and mercantile vaults, refer to the following documents: ASTM Specifications A 184/A 184M, A 615/A 615M, A 635/A 635M, C 33, C 94/C 94M, C 150, C 494/C 494M, C 618, C 685/C 685M; American Concrete Institute Building Requirements ACI 318, and American Welding Society Structural Welding Code D 1.4.

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