There are a number of ASTM standards related to odour assessment and regulation:

• ASTM E679-04 United States ‘standard practice for determination of odour and taste threshold by a forced-choice ascending concentration series method of limits’
• D1292 test method for odour in the water
• E544 practices for referencing suprathreshold odour intensity
• E1432 practice for defining and calculating individual and group sensory thresholds from forced-choice data sets of intermediate size

The ASTME679-04 is the most commonly used standard in the USA for olfactometry, however, outside of the USA, EN13725 standard is more commonly accepted.
