According to StatNano, 1422 nanotechnology standards have been published by consensus and approved by 42 recognized bodies since 1992. A comparison of these standards over the past three years in Figure 1 shows a conspicuous drop in 2019 so that 154 standards were published, most of which were adopted by national organizations (ca., 77.9 %), and the rest were made available to the public by international (ca., 15.6 %) and regional (ca., 6.5 %) bodies, respectively.
Figure 1. The number of published nanotechnology standards between 2015 and 2019.
As shown in Table 1, the UK, Italy, Denmark, Austria, Spain, the Netherlands, Sweden, France, Belgium, Iran, Estonia, Finland, Russia, China, Bulgaria, Germany, Australia, and Norway were the pioneering countries in nano-related standards publications in the past year, paying particular attention to nanotechnology exploitation. Accordingly, 21 organization bodies of ISO, BSI, UNI, DS, ASI, CEN, AFNOR, NEN, SIS, AENOR, NBN, ISIRI, EVS, SFS, GOSTR, SAC, BDS, DIN, SA, IEC, and SN made the highest contributions to the standardization of nanotechnology-based products, services, and systems in 2019.

It is worth mentioning that a broad spectrum of the published national standards were an adoption of either the regional or international bodies, among which EN 17199:2019 (parts 2-5), ISO/TS 21083:2019, ISO/TS 16195:2018, CEN/TS 17273:2018, CEN/TS 17274:2018, and CEN/TS 17275:2018 received the highest shares (Table 2).

These standards fell into six different categories, 48.3 % of which were included in the Test Method| Characterization| Measurement category. Specifications ranked second with around 30.9 %, and the Guide|Practice, Terminology| Vocabulary| Definition, Management System, and Classification| Categorization categories took the next places, having approximately 8.7, 6.7, 4.7, and 0.7 %, respectively, as shown in Figure 2. Most of these standards aim to ensure the risks of the workplace exposure of nano-objects (e.g., nanoparticles, nanopowders, and nanosuspensions) in the chemical industrial sector, more especially in catalysts, paints, and resins production. In addition, such carbon-based structures as carbon black, carbon nanotubes, and graphene are the most common nanomaterials discussed in these standards.
