ANSI E1.15-2006 pdf download American National Standard E1.15 – 2006 Entertainment Technology Recommended Practices and Guidelines for the Assembly and Use of Theatrical Boom & Base Assemblies
4.2.1 Slope Test The stability of the assembly shall be acceptable if the assembly remains upright when placed on a surface inclined 5-degrees off horizontal (refer to Figure 1). Where loads are unevenly distributed about the centerline of the vertical member, the assembly shall be oriented on the incline such that the greatest load is placed towards the lower side of the slope.
4.2.2 Horizontal Force Test The stability of the assembly shall be acceptable if the assembly remains upright without toppling when placed on a level surface, and subjected to a horizontal force applied to the vertical member, and at any point above its midpoint. The applied force shall be a gradually applied dynamic load, suficient to tip the vertical member a minimum of 10-degrees off vertical without damaging the assembly, or dislodging its attachments.
4.2.3 Rotation Due to Tipping Action The tests described in sections 4.2.1 and 4.2.2 above shall consider any rotation of the assembly that may result from tipping actions.* Any application in which a tipping action results in a foreseeable rotational shiting of the loads shall require further evaluation and approval by a qualified person. In applications not fully evaluated by a qualifed person, supplemental stabilizing methods shall be used.
4.2.4 Remidies for Failed Test The following standard stabilizing methods shall be applied to any assembly failing the test proce- dures outined above, and shall be applied (in any order or combination) until the assembly SUC cessfully passes the testing requirements, but shall not restrict the application of other remedies provided that the intent of this section is met: a. Attached loads shall be shifted to improve load distribution about the vertical member, or to lower the assembly’s center of gravity; b. Attached loads shall be removed; Any remedy that requires the use of supplementary stabilzing methods, as described in Section 6.5 below, shall also require evaluation and approval by a qualifed person.
5 Assembly Guidelines
5.1 Personnel Requirements The assembly of the portable boom and base devices shall be performed by competent persons, who shall have read and understood the manufacturer’s instructions referenced in Section 10 below. To ensure safe assembly of the device, where the device height exceeds 3 meters (10 feet) two or more persons shall complete the assembly.
5.2 Order of Assembly Guidlines Device assemblers and users shall fllw all manufacturer’s order of assembly guidelines, as refer- enced in Section 10 below. E。enEntu Drnnnustinne
