3.2.3.4 Components included or excluded. Documentation shall include materials, components, processesand methods used to construct the display system.Aesthetic aspects, electronic circuitry or electrically poweredcomponents are not required in the documentation unless such elements are integral to the strength or safety ofthe display system.
3.2.3.5 Working Load Limit (WLL). The designer of the display system shall publish a WLL for components andassemblies covered by this standard.The working load of a component or assembly shall be determined by theoriginal equipment manufacturer and explained in the documentation.Connection hardware design factors shallnot be less than 5, based on the ultimate strength of the component,unless otherwise approved by a qualifiedperson.
3.3 component Part Security.
Component parts shall not loosen or become dislodged during use.
3.3.1 Attachment and Suspension Components
Attachment and suspension hardware shall be constructed of materials that are appropriate for the intended use,as determined by a qualified person.
3.3.1.1 Design Quality. Lifting media, attachment and suspension hardware shall be designed by a qualifiedperson in accordance with acceptable engineering practice for specific display system conditions, or shall betested in accordance with Section 3.3.2 Testing.
3.3.1.2 Design Calculations or Testing Results. Design calculations or testing results shall validate the litingmedia, attachment and suspension hardware strength, and shall show that the suspension hardware meetsdesign factor requirements and shall show that it is fit for the intended purpose.
3.3.1.3 Repeatability. The testing results shall be repeatable for all material batches of individual components,where their respective material properties may vary for any reason due to component manufacturing processes.
3.3.1.4 Tolerances.The testing results shall be repeatable within an acceptable tolerance as determined by aqualified person.
3.3.1.5 Hardware connections.Each hardware component specifically used for suspension shall be affixed to aminimum of one (1) structural surface of the display system. There shall be no less than two suspension pointsprovided for any overhead suspension application unless otherwise determined by RA/RR . The hardware shallbe affixed to the display system with the aid of a reinforcement device so as to prevent all reasonable and
foreseeable failure of the display system’s structural material. The forces imposed on the entire display systemshall not exceed its design capacity.All orientations allowed by the manufacturer shall be considered.
3.3.1.6 Corrosion Resistance. Attachment and suspension hardware shall be corrosion resistant when theforeseeable intended use criteria includes exposure to moisture or other similarly corrosive environments.
3.3.1.7 Strength.*All suspension attachment hardware, methods and associated connections in the suspensionload path shall be designed using a working 4.1 load limit design factor of not less than 5 based on the attachment and suspension hardware ultimate strength,unless otherwise approved by a qualified person.
3.3.2 Testing. Where designs cannot be analytically proven, structural load path elements shall be tested.3.3.2.1 Test methods shall be approved and supervised by a qualified person
3.4 Installation conditions*
Aspects of the installation environment affecting RA/RR, OMP or engineering requirements shall be considered,and shall be incorporated into the design process accordingly.
In addition to the general requirements of section 3, indoor and outdoor ground supported systems shall comply with ANSI E1.21 as applicable to the type of support structure used and the environment in which the system is installed.
3.5 Suspended systems
Suspension components shall be designed for overhead lifting.
3.5.1 Stabilizing and positioning. Where systems require the use of positioning, breasting or stabilizing points,the resulting connections and forces shall be accounted for in the design.
3.5.2 Connection points. All load-bearing connections, whether for lateral, vertical or combined forces, shall be designed by a qualified person.ANSI ESTA E1.50-1 pdf download.
