Section 535-X-13-.09 - Standards For The Manufacture Of Anchor And Tiedown Devices
Current through Register Vol. 42, No. 5, February 29, 2024
(1) All manufacturers of ground anchors and tiedown devices must have the approval of their products by the Alabama Manufactured Housing Commission before offering their products for sale and use within the State of Alabama.
(2) All anchors and tiedown devices used in the State of Alabama for the purpose of anchoring a manufactured home or building to the ground must be tested by a third party independent testing agency, recognized by the Commission as having the technical background and experience in testing ground anchors and tiedown devices. The third party agency cannot have any interest or ties with the manufacturer which the agency is testing. There can be no conflict of interest between the agency and the manufacturer.
(3) All anchors and tiedown devices shall be tested to a minimum of 4,725 lbs. The combined vertical displacement attributed to the elongation of the anchor and withdrawal from the substrate shall not exceed 2" at an applied load of 4,725 lbs. Anchors tested with loads applied at an angle to the anchor shaft shall not displace the anchor more than 3" horizontally at an applied load of 4,725 lbs.
(4) Anchors designed for connection of multiple ties must be capable of resisting the combined loads placed upon such anchors. The displacement cannot exceed 2" vertically and 3" horizontally.
(5) All tiedown devices shall be tested with the same loads as the ground anchors. Failure of the tiedown devices and ground anchors shall be considered as breakage, bending or slippage that results in excessive yielding at 2" vertically and 3" horizontally at an applied load of 4,725 lbs. or with combined loads.
(6) A complete product description shall be provided for each anchor and each tiedown device tested and submitted for approval. The information shall include the following:
(7) Any change from the engineered drawings (metal size, welding alterations, coatings, etc.) as well as significant changes in the quality assurance program will nullify the approval.
(8) A test report is required to accompany each anchor or tiedown device submitted for approval and shall be sufficiently detailed so that the test can be replicated without a requirement for additional information. The test report shall include the following:
(9) All test procedures should conform to the applicable ASTM Standards:
