UNE-EN ISO 11132:2017

This International Standard gives guidelines for monitoring and assessing the overall performance of aquantitative descriptive panel and the performance of each member.A panel of assessors can be used as an instrument to assess the magnitude of sensory attributes.Performance is the measure of the ability of a panel or an assessor to make valid attribute assessments acrossthe products being evaluated. It can be monitored at a given time point or tracked over time. Performancecomprises the ability of a panel to detect, identify, and measure an attribute, use attributes in a similar way toother panels or assessors, discriminate between stimuli, use a scale properly, repeat their own results, andreproduce results from other panels or assessors.The methods specified allow the consistency, repeatability, freedom from bias and ability to discriminate ofpanels and assessors to be monitored and assessed. Monitoring and assessment of agreement between panelmembers is also covered. Monitoring and assessment can be carried out in one session or over time.Monitoring performance data enables the panel leader to improve panel and assessor performance, toidentify issues and retraining needs or to identify assessors who are not performing well enough to continueparticipating.The methods specified in this International Standard can be used by the panel leader to appraise continuouslythe performance of panels or individual assessors.This International Standard applies to individuals or panels in training as well as for established panels.
