This practice establishes performance specifications and performance standards for the design, manufacture, installation, and testing of climbing nets and netting/mesh used in amusement rides, devices, play areas and attractions. The materials are: hardware and structures, climb nets, barrier nets, fire retardant, no-hold netting, debris net, and safety nets. Netted areas shall be designed and constructed or assembled so that any accessible net opening shall meet the performance requirements and test requirements. The following tests procedures shall be done: in place test for climb net or barrier net, prototype test for barrier and no-hold netting, prototype test for maximum hole size of no-hold netting, prototype test for a safety net, test for hard nodes, and test for nets with large openings. Installation shall meet the requirements for attachments, fasteners and hardware, and operational performance specified here.
