(Note that the new AGMA specification requires a FZG result >12 load stages butdoes not include Timken, Four Ball Wear and Four Ball Weld performance, as previouslyrequired in the US Steel No. 224 specification that is shown for reference.)The data also show that 0.3% NA-LUBE AW-6310 can be added to an R&O oil containing0.7% NA-LUBE BL-1208 to meet the AGMA 9005-E02 Industrial Gear Oil Specification,however, this blend does not show as good EP performance as the NA-LUBE BL-1208/KX1236 blend, as noted using the Four Ball Weld test.
