1.1 Thisspecification covers the design, testing, manufacture, selection,and installation of fabricated metal access hatches for utility,water, and wastewater structures including utility vaults, drainagestructures, valve vaults, meter vaults, wet wells, pump enclosures,utility trenches, piping trenches, and drainage trenches.

1.2 Thisspecification is applicable to various configurations of accesshatches constructed of fabricated metal of various materials andgrades for various loading conditions, traffic speeds, or both.

1.3Engineering design and testing criteria are provided for accesshatches to be located in various areas subjected to various loadingconditions, traffic speed, frequency, or combinations thereof.

1.4Proof loading criteria is provided to allow the access hatches tobe designed by engineering calculation and/or by ultimate strengthload testing.

1.5Production loading criteria is provided to allow the access hatchesto be tested to verify the load capacity of the manufacturedhatches.

1.6Hatch loading selection guidelines are included to allow selectionof the proper hatch design loading for the conditions of the actualarea of placement.

1.7 Thevalues stated in inch-pound units are to be regarded as standard.The values given in parentheses are mathematical conversions to SIunits that are provided for information only and are not consideredthe standard.

1.8This standard does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety,health, and environmental practices and determine the applicabilityof regulatory limitations prior to use.

1.9This international standard was developed in accordance withinternationally recognized principles on standardizationestablished in the Decision on Principles for the Development ofInternational Standards, Guides and Recommendations issued by theWorld Trade Organization Technical Barriers to Trade (TBT)Committee.
