OXYMAG FLOOR BOARDS DESIGN & LOAD TABLES OxyMag floor boards have been independently tested and certified to meet NCC/BCA Deemed-to-Satisfy structural requirements for floor loadings to AS/NZS 1170.1 Table 3.1 The following tables are provided to inform designers, engineers and relevant users of: • the maximum concentrated and uniformly distributed actions that the Oxymag floor boards have been designed to withstand; and • the applications for which the Oxymag floor boards are suitable using Table 3.1 in AS/NZS 1170.1 as the basis. These load tables are based on the following assumptions: • The Oxymag floor boards will be installed in accordance with the details described in the Oxymag Installation guide including: o their lengths will be laid across the joists; o their short edges will be fully supported on joists; o their long edges will be fully supported at stair treads or landings; o their long groove edges will be filled with a continuous bead of approved joint sealant prior to the adjacent board's tongue being slotted into the groove. o they will be dry when being installed and thereafter. • The design will include 1kPa of super-imposed dead action as well as the weight of the board. • The design will adopt a serviceability limit G + ψQ = span/300.
1. Concentrated Actions a. AS/NZS 1170.1 (Table 3.1) specifies the following reference values of concentrated floor actions: i. For residential applications, a concentrated action of 1.8kN applied to a minimum area of 350mm2. ii. For commercial and other applications, concentrated actions of 2.7kN or above (depending on the specific application) applied to a minimum area of 0.01m2 (100mm x 100mm). b. In the context of AS/NZS 1170.1’s requirements, TABLE 1 below reflects the maximum allowable concentrated actions to be applied to the 16mm and 19mm thick Oxymag floor boards. Note: A combination factor of 1.5 applies. TABLE 1: MAXIMUM ALLOWABLE CONCENTRATED ACTIONS - kN Thickness (mm)

Notes: 1. The maximum concentrated action of 1.8kN for domestic & residential activities shall be applied over a minimum area of 350mm2 for calculation of punching or crushing.
2. Uniformly Distributed Actions a. AS/NZS 1170.1 (Table 3.1) also specifies reference values of uniformly distributed floor actions which vary depending on the specific application. b. In the context of AS/NZS 1170.1’s requirements, TABLE 2 below reflects the maximum allowable uniformly distributed actions to be applied to the 16mm and 19mm thick Oxymag floor boards. Note: A combination factor of 1.5 applies.
