The next time you reach for a phone charger, discuss the barrier properties of gowns, or rely on the filtration performance of geosynthetics, remember: you are benefiting from a silent, global consensus. Most of us navigate our days leaning on a hidden scaffolding of safety and logic. We do not wonder if a light bulb will fit its socket or if a medical gown will truly repel fluids in an operating theatre. We take these things for granted because, beneath the surface of international commerce, there is a foundation of standards that dictates how the world ought to function.
At the heart of this invisible architecture sits the International Organization for Standardization (ISO). While the term "standardization" may evoke images of grey corridors, the reality is far more dynamic. These standards are the precursors to the laws of tomorrow – a unique form of international diplomacy where science, industry, and public interest converge to define "safe" or "sustainable" before a single line of legislation is ever drafted.
A legacy of interoperability: The birth of ISO
The story of ISO began in the ashes of the Second World War. In 1946, delegates from 25 countries met at the Institute of Civil Engineers in London to “facilitate the international coordination and unification of industrial standards.” By February 1947, ISO officially began operations. Its roots, however, go deeper. It was built upon the foundations of the International Federation of the National Standardizing Associations (ISA), which in the 1920s and 1930s focused heavily on mechanical engineering and industrial standards. After the Second World War, governments and industry saw an urgent need to coordinate and unify technical standards in order to support reconstruction, international trade and industrial compatibility. If the world were to rebuild efficiently, the parts, measurements and systems used in different countries needed to work together.
What began with nuts, bolts, and maritime components soon expanded into every facet of human endeavour. In the 1950s, ISO moved into the realm of film speeds and cargo containers—the latter of which revolutionized global trade by ensuring a box from Shanghai would fit into a crane in Antwerp. By the late 20th century, the focus shifted from purely physical dimensions to management systems, environmental impact, and healthcare. Today, with over 25,000 standards, ISO is the quiet engine of the global economy.
The logic of common ground
Why do organizations like ISO exist? Without them, the global market would be a cacophony of fragmented systems. Imagine a world where every manufacturer of medical devices used a different metric for fluid resistance, or where "biodegradable" meant ten different things across ten different borders. Such fragmentation creates uncertainty for the consumer and insurmountable barriers for the innovator.
Standards provide a common technical language. They ensure that a protective garment manufactured in South Carolina meets the same rigorous safety benchmarks required by a hospital in Stockholm. By establishing agreed-upon testing methods, standards reduce risk and foster trust. They allow companies to compete on the quality of their products rather than the obscurity of their measurements.
The standardization ecosystem: Both upstream and downstream paths
There is a common misconception that ISO is a "top-down" monolithic set of mandates handed down from Geneva. In reality, the process is a sophisticated ecosystem of upstream and downstream flows. The "upstream" flow often begins at the national level. National standardization bodies (NSBs)—such as AFNOR in France, DIN in Germany, or NBN in Belgium—are the true laboratories of consensus. A technical breakthrough or a safety requirement often starts as a national standard. Once it proves its mettle, it is pushed "upstream" to ISO to be globalized.
Conversely, the "downstream" flow occurs when ISO sets a global benchmark that is then adopted and refined by national bodies to fit local legal frameworks. ISO functions not as a central orchestrator, but as a global hub, harmonizing the expertise that bubbles up from individual nations.
In the European context, this relationship takes on a political dimension through CEN (the European Committee for Standardization). Within the EU, standardization is a powerful tool for Single Market integration, but its influence extends far beyond the continent’s borders. This is a strong driver of the so-called "The Brussels Effect," where the EU’s high regulatory and technical benchmarks effectively become the global default.
When EU member states align on a standard within CEN, it creates a formidable voting bloc. Think of it as the United Nations of industry: because ISO operates on a "one country, one vote" system amongst participating members (called ‘P’ members), a synchronized Europe can effectively steer the global direction of "state-of-the-art" technology. By the time a standard reaches the global stage, the consensus reached in Brussels has often already set the pace for the rest of the world.
It is a common misconception that industry merely reacts to the whims of regulators. In reality, the technical substance of regulation is often born within ISO or CEN (the European Committee for Standardization) technical committees long before a directive is debated in Brussels or in the European capital cities. Governments and regulators rarely possess the hyper-specialized technical expertise required to define the molecular stability of a polymer or the precise airflow of a ventilator. Instead, they look to existing international standards as a "state of the art" benchmark which will later become the regulatory foundations.
The nonwovens industry: A partner in progress
This relationship between standards and the public good is nowhere more evident than in the nonwovens industry. Nonwovens are the "hidden" high-tech fabrics found in hygiene products, surgical drapes, water filtration systems, and the geotextiles that stabilize our bridges and motorways. Because these products often sit at the intersection of health, safety, and environmental protection, the industry cannot afford to be passive. Through EDANA, the leading international association for the nonwovens and related industries, the sector takes a proactive stance. By participating in standardization, the industry ensures that the frameworks governing its products are science-based, practical, and effective.
EDANA’s seat at the ISO technical table is crucial, as we aim to be at the heart of where standards are being defined and bring all our expertise from an industry perspective.
Through its active leadership in various technical committees, EDANA ensures that the unique properties of nonwovens are accurately represented in global standards. This involvement spans from defining the industry’s fundamental vocabulary and testing methods in ISO/TC 38/WG9 to setting critical safety benchmarks for personal protective clothing (ISO/TC 94) and surgical drapes (CEN/TC 205), where precise measurements of barrier performance directly impact patient outcomes. Beyond healthcare, EDANA’s expertise helps navigate the complexities of the circular economy by working within ISO/TC 224 to harmonize technical criteria for the 'flushability' of wipes. This process aims to establish a science-based consensus that protects municipal infrastructure while providing clear, transparent guidance for consumers and manufacturers alike. Whether ensuring the dermatological safety of the incontinence and menstrual products categories (ISO/TC 173 and TC 338) or the structural integrity of geosynthetics in civil engineering (CEN/TC 189), EDANA’s seat at the table guarantees that international benchmarks remain practical, innovative, and grounded in industry reality.
A forward-looking consensus
Standardization is often mischaracterized as a barrier to innovation. In fact, the opposite is true. By establishing a baseline of safety, standards allow engineers to focus on making a better product rather than reinventing the unit of measurement.
As we look toward a future defined by climate change and evolving public health needs, the role of ISO and CEN will only grow. The nonwovens industry, through EDANA, remains committed to this collaborative process. We believe that the best way to prepare for future regulation is to help build the scientific and technical foundations upon which that regulation will eventually rest.
Standardization is a testament to what we can achieve when expertise, industry, and public interest find a common language. It is the quiet, persistent work of building a world that works—not just for today, but for the generations to follow.
