1 Gaussian curves (normal distribution for different
standard deviations)
2 Limits corresponding to 1, 2 and 3 times the standard

This International Standard describes the fundamental characteristics of dimensional variability in building and of the particular case of combination of random unrelated variables; it sets out the need to relate dimensional variability to the limits imposed on joint widths by the need for satisfactory functioning.
