WHAT IS ISO/IWA 15 ?
ISO (International Organization for Standardization) is an independent, non-gov-ernmental membership organization and the world’s largest developer of voluntary international standards. Now a familiar factor worldwide in industry and commerce, ISO has a large influence in healthcare, and is committed to promoting harmonization of practices, protecting patient safety, supporting efficient information exchange, and improving the quality of care.
ISO/IWA 15 is a consensus document developed by the workshop participants and observers in response to the need for standardization and harmonization of volumetric performance determination for Automated Liquid Handling Systems (ALHS). This document is the first step to a series of ISO standards addressing this topic.
The principal objective of ISO/IWA 15 is to develop a standards framework within which the users and manufacturers of ALHS can manage the performance and use of these devices.
ISO/IWA 15 describes ALHS test methods, volumetric performance measurement concepts, and descriptive statistics, as well as information to be presented on test reports.
The ISO/IWA 15 workgroup includes representatives from the liquid handling manufactur-ers, calibration providers, and end-users of automated liquid handling instrumentation. The workgroup is continuously open for comment and support from all interested parties.
EXPECTED IMPACT OF STANDARDIZEDMETHODS • Increased efficiencies within, and between, research laboratories.
• Faster development time lines.
• More efficient pursuit of medical advancements.
• Less expensive and more available diagnostics and pharmaceuticals.
• More successful development programs and manufacturing processes of automated liquid handling instrumentation and related laboratory tools essential to healthcare science.
GLOBAL STANDARDIZATIONISO 8655 standardizes the performance determination of non-automated mechanical liquid handling devices, while ISO/IWA 15 addresses automated devices. Both documents harmonize liquid handing performance determination across technology platforms, laboratories and geographic regions.

AUTOMATED LIQUID HANDLING SYSTEMS STANDARDS – PRESENT AND FUTURE
Evolution of liquid handling technology toward smaller volumes requires continued
development of increasingly sensitive methods for performance measurement.
Harmonization between test methods is necessary for most efficient laboratory
processes. To date, two ISO standards have been developed for non-automated
liquid handling devices: ISO 4787 for Class A glassware and ISO 8655 for mechanical
piston-operated devices.
The need for standardized measurement methods, statistical analyses, and reporting
requirements for ALHS volumetric performance determinations led to the development
of ISO/IWA 15 under the direction of ISO Technical Committee 48 (ISO/TC 48) -
Laboratory Equipment. It is proposed to develop a series of ISO standards on the basis
of the concepts described in ISO/IWA 15. Consideration of this proposal is being led by
Working Group 04 (WG04) in ISO/TC 48.

CONTEXT FOR THE WORK
The ISO/IWA 15 project exists in the context of the global challenge to meet society’s
needs for affordable, appropriate and available healthcare. Regardless of regional, cultural
or political differences in the approach to healthcare, there is universal agreement that
it is a critical component to progress of any kind - for all societies worldwide. • Affordable: A need for less costly testing, treatment, cure and maintenance.
• Appropriate: A need for accurately executed diagnosis and precisely targeted treatment.
• Available: A need for broader, more timely access to healthcare.
None of these three challenges can be met without more efficient and faster programs in
life science laboratories – to develop new, more effective and less expensive diagnostic
procedures and therapeutic agents. A critical factor in reaching these healthcare goals,
especially as the technical challenges become more complex and involve numerous
parties, is a common system of applied measurement. Without such a system, research
effectiveness and productivity drops, coordination is difficult, costs escalate, needless
complexities arise – and progress suffers dramatically. All of the worthwhile pursuits of
science have been catalyzed by a common system of measurement.
SPECIFIC CONTRIBUTIONS
The ISO/IWA 15 project is envisioned to result in a set of ISO standards specific to users
and manufacturers of automated liquid handling systems. These elements are essential to
development and manufacturing in life sciences – and therefore to meeting the larger
challenges of improved healthcare globally.
ISO/IWA 15 includes:
• Definitions of technical terminology and concepts describing volumetric performance.
• Test methods and descriptive statistics for volume performance determination.
• Guidance for users, developers and manufacturers, including descriptions of testing environments, operating ranges, maximum permissible errors, and reporting requirements.
• Recommendations for continuing work towards a set of ISO standards for ALHS.
