Currently there are three standards in the process of development. These are:
Study Group

Use Cases (led by Dr. Gopalakrishna Kuppa):
Study Group
Chair: Susan Schiffman
Secretary: H. Troy Nagle
Members:

Ehsan Danesh et al.
(about 20 listed members with 10 to 12 being most active. Several members are officers of ISOCS (International Society for Olfaction and Chemical Sensing). One of them is considered to be one of the founders of the eNose field.)
Over the last two years, this WG has initiated five new WGs focusing on standards specific odor monitoring applications. The original P2520 WG is evolving from a “standard” into a “recommended practices” document. Below are summaries of the recent activities of the five new WGs.
P2520.1™ Baseline Performance for Odour Analysis Devices and Systems: This standard is based on initial concepts developed in P2520 through late 2019 and 2020. All machine olfaction devices must first pass this standard before moving onto a more targeted standard. Due to the broad spectrum of instrument types that will adhere to the standard, the baseline performance of all instruments is to be compared at a simple level. The standard requires the instruments to measure and quantify three test chemicals. It also requires operational stability over a number of days and evaluates the performance in different environmental conditions (changes in humidity and temperature).
P2520.2.1™ Machine Olfaction Devices and Systems Used for General Outdoor Odour Monitoring: WG meetings officially kicked off in February 2021 and since then, members have focused on identifying gaseous chemicals responsible for outdoor malodour events and their relevant concentrations. A special attention has been paid to understand past and ongoing international efforts in standardizing odour measurement.
P2520.2.2™ Landfill Odour Monitoring Devices and Systems: P2520.2.2 will build upon P2520.1 and P2520.2.1. Therefore, participants interested in the new P2520.2.2 WG are meeting informally with P2520.1 and P2520.2.1. P2520.2.2 will formally kick-off and work independently once the scopes of those two foundational standards have been defined.
P2520.3.1™ Machine Olfaction Devices and Systems Used for General Indoor Odour Monitoring: The focus of this standard is devices that are designed to monitor nuisance odors in indoor environments in which volatile organic compounds (VOCs) frequently produce noxious smells and/ or impose safety risks.
P2520.4.1™ Performance of Machine Olfaction Devices and Systems for Chemical Manufacture: This WG aims to develop performance testing protocols for monitor odors from chemical manufacturing facilities (e.g., pharma, biotech, paints, solvents, chemicals). The WG gathers a multidisciplinary group of academic researchers, sensors manufacturers, and odor monitoring experts and will build upon P2520.1. The initial focus of the WG is to understanding the specific requirements for chemical manufacture odor monitoring, selecting test chemicals, and evaluating testing setups in order to produce a draft outline for the standard during 2021.
For individuals who are interested in participating in one or more of these Working Groups, please contact the WG Chairs through their respective WG websites.
