Figure 4.
The plot shows four samples on the horizontal axis with air permeability represented by vertical bars against the left axis in cubic metres per square metre per minute and coefficient of variation marked by points against the right axis in percent. Sample 1 shows permeability near 50 and variation near 2. Sample 2 shows permeability near 75 and variation slightly above 2. Sample 3 shows permeability near 40 and variation near 1.5. Sample 4 shows permeability near 55 and variation near 0.5. Both axes include evenly spaced grid lines.Results of air permeability
