OECD

The Organisation for Economic Co-operation and Development (OECD, https://www.oecd.org/) is an international intergovernmental organisation that works towards shaping policies that foster prosperity, equality, opportunity and well-being for all.

In its programme on Chemical Safety and Biosafety, the OECD assists countries in developing and implementing policies and instruments that make their systems for managing chemicals as efficient and robust as possible, while protecting human health and the environment. The Mutual Acceptance of Data (MAD) system helps to avoid conflicting or duplicative national requirements, provides a common basis for co-operation among national authorities and avoids creating non-tariff barriers to trade. OECD countries and full adherents have agreed that a safety test carried out in accordance with the OECD Test Guidelines and Principles of Good Laboratory Practice in one OECD country must be accepted by other OECD countries for regulatory assessment purposes. This is the concept of “tested once, accepted for assessment everywhere”. Apart from saving large amounts of test animals, this saves the chemicals industry the expense of duplicate testing for products which are marketed in more than one country. The OECD test guidelines may be complemented by ISO or CEN standards that give precise instructions, e.g. for executing part of such testing or for testing individual chemicals.

In the OECD Test Guideline Programme, the Test Guidelines for the Mutual Acceptance of Data (MAD) system are continuously expanded and updated to ensure they reflect the state-of-the-art science and techniques to meet member countries regulatory needs. The Guidelines are elaborated with the assistance of experts from regulatory agencies, academia, industry, environmental and animal welfare organisations.

The OECD Guidelines for the Testing of Chemicals are a unique tool for assessing the potential effects of chemicals on human health and the environment. They are split into five sections: Section 1: Physical-Chemical properties; Section 2: Effects on Biotic Systems; Section 3: Environmental fate and behaviour; Section 4: Health Effects and Section 5: Other Test Guidelines (with a focus on pesticides and their residues). Accepted internationally as standard methods for safety testing, the Guidelines are used by professionals in industry, academia and governments involved in the testing and assessment of chemicals (industrial chemicals, pesticides, personal care products, etc.). as such they former a cornerstone under the OECD Mutual Acceptance of Data (MAD) system.

OECD Series on Testing and Assessment The OECD Series on Testing and Assessment includes publications related to testing and assessment of chemicals. Documents include but are not limited to Guidance Documents to (further) support the use of Test Guidelines, Case Study Reports on Integrated Approaches to Testing and Assessment (IATAs), Validation Study Reports in support of newly developed Test Guidelines, but also other Study Reports or Dedicated Review Papers.

OECD Series on the Safety of Manufactured Nanomaterials The purpose of the OECD Series on the Safety of Manufactured Nanomaterials is to provide up-to-date information on the OECD activities on manufactured nanomaterials that are related to human health and environmental safety. Documents include but are not limited to Guidance Documents to (further) support the assessment of nanomaterials, workshop reports on applicability of Test Guidelines for nanomaterials, overviews of activities on nanomaterials in the different member countries (so called Tour de Table documents), or outputs from the OECD Testing Programme on nanomaterials.

ISO

The International Organisation for Standardisation ISO is an independent, non-governmental international organization. ISO develops and publishes standards for any conceivable aspect of measuring and describing nanotechnologies, except regulatory methods. Methods for regulatory testing are developed by OECD, although the OECD test guidelines may be complemented by ISO standards that give precise instructions e.g. for executing part of such testing or for testing individual chemicals. ISO standards are internationally agreed by experts.

International Standards An International Standard provides rules, guidelines or characteristics for activities or for their results, aimed at achieving the optimum degree of order in a given context. It can take many forms. Apart from product standards, other examples include: test methods, codes of practice, guideline standards and management systems standards.

Technical Specification A Technical Specification addresses work still under technical development, or where it is believed that there will be a future, but not immediate, possibility of agreement on an International Standard. A Technical Specification is published for immediate use, but it also provides a means to obtain feedback. The aim is that it will eventually be transformed and republished as an International Standard.

Technical Report A Technical Report contains information of a different kind from that of the previous two publications. It may include data obtained from a survey, for example, or from an informative report, or information of the perceived “state of the art”.

Publicly Available Specification A Publicly Available Specification is published to respond to an urgent market need, representing either the consensus of the experts within a working group, or a consensus in an organization external to ISO. As with Technical Specifications, Publicly Available Specifications are published for immediate use and also serve as a means to obtain feedback for an eventual transformation into an International Standard. Publicly Available Specifications have a maximum life of six years, after which they can be transformed into an International Standard or withdrawn.

International Workshop Agreements An International Workshop Agreement is a document developed outside the normal ISO committee system to enable market players to negotiate in an “open workshop” environment. International Workshop Agreements are typically administratively supported by a member body. The published agreement includes an indication of the participating organizations involved in its development. An International Workshop Agreement has a maximum lifespan of six years, after which it can be either transformed into another ISO deliverable or is automatically withdrawn.

Guides Guides are just that. They help readers understand more about the main areas where standards add value. Some Guides talk about how, and why, ISO standards can make it work better, safer, and more efficiently. Full list of Guides available in the ISO Catalogue.

ISO is subdivided in different technical committees, which are dedicated to specific topics.

ISO/TC 229 Nanotechnologies The technical committee ISO/TC 229 Nanotechnologies works towards standards applicable to nanomaterials. Specific tasks include developing standards for terminology and nomenclature, metrology and instrumentation, including specifications for reference materials, test methodologies, modelling and simulations, and science-based health, safety, and environmental practices.



European Committee for Standardization (CEN)

The European Committee for Standardization is one of three European Standardization Organizations that have been officially recognized by the European Union and by the European Free Trade Association (EFTA) as being responsible for developing and defining voluntary standards at European level. CEN works close in a liaison with ISO , and as such CEN develops and publishes standards for any conceivable aspect of measuring and describing nanotechnologies, except regulatory methods. Nevertheless, CEN standards may complement OECD Test Guidelines by giving precise instructions e.g. for executing part of such testing or for testing individual chemicals. An overview of standards can be found here: https://standards.cencenelec.eu/dyn/www/f?p=CEN:105::RESET

Here we focus on the Technical Committees that are most relevant for nanomaterials.

CEN/TC 352 Nanotechnologies CEN/TC 352 develops standards on classification, terminology and nomenclature, metrology and instrumentation, test methods modelling and simulation and more, related to nanotechnologies and nanomaterials. The TC works closely with the international committee ISO/TC 229 Nanotechnologies and has published more than 15 EN ISO documents, addressing topics of global relevance and avoiding the duplication of work at European and international level.

CEN/TC 195 Cleaning equipment for air and other gases The scope of CEN/TC 195 is standardization in the fields of terminology, classification, characteristics, and test and performance methods for air and gas cleaning equipment for general ventilation and industrial applications.

CEN/TC 137 Assessment of workplace exposure to chemical and biological agents CEN /TC 137 focusses on the standardization in the field of assessment of exposure to agents at the workplace including the planning and performing of measurement but excluding the establishment of limit values.

OECD TG 124: Determination of the Volume Specific Surface Area of Manufactured Nanomaterials https://www.oecd-ilibrary.org/environment/test-no-124-determination-of-the-volume-specific-surface-area-of-manufactured-nanomaterials_abb72f8f-en This Test Guideline (TG) describes a harmonised procedure to determine the Volume Specific Surface Area (VSSA) of powdered solid manufactured nanomaterials (MNs). The VSSA (in m²/cm³) of a material is calculated by multiplying its mass specific surface area (in m²/g) with its skeletal density (in g/cm³). The determination of the external and internal (mass) specific surface area (SSA) of powdered solid MNs is done by the Brunauer, Emmett and Teller (BET) method. This TG also provides instructions on how to determine the skeletal density (ρ) of the MN by gas pycnometry.
OECD TG 125: Nanomaterial Particle Size and Size Distribution of Nanomater https://www.oecd-ilibrary.org/environment/test-no-125-nanomaterial-particle-size-and-size-distribution-of-nanomaterials_af5f9bda-en This Test Guideline, covering nanomaterials spanning from 1 nm to 1000 nm, is intended for particle size and particle size distribution measurements of nanomaterials. The TG includes the following methods: Atomic Force Microscopy (AFM), Centrifugal Liquid Sedimentation (CLS)/Analytical Ultracentrifugation (AUC), Dynamic Light Scattering (DLS), Differential Mobility Analysis System (DMAS), (Nano)Particle Tracking Analysis (PTA/NTA), Small Angle X-Ray Scattering (SAXS), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM). For measuring the diameter and length of fibres, analysing images captured with electron microscopy is currently the only method available.

OECD TG 412: Subacute Inhalation Toxicity: 28-Day Study https://www.oecd-ilibrary.org/environment/test-no-412-subacute-inhalation-toxicity-28-day-study_9789264070783-en This revised Test Guideline 412 (TG 412) has been designed to fully characterize test article toxicity by the inhalation route following repeated exposure for a limited period of time (28 days), and to provide data for quantitative inhalation risk assessments.  It was updated in 2017 to enable the testing and characterisation of effects of nanomaterials tested. Groups of at least 5 male and 5 female rodents are exposed 6 hours per day for 28 days to a) the test chemical at three or more concentration levels, b) filtered air (negative control), and/or c) the vehicle (vehicle control). Animals are generally exposed 5 days per week but exposure for 7 days per week is also allowed. Males and females are always tested, but they may be exposed at different concentration levels if it is known that one sex is more susceptible to a given test article. This guideline allows the study director the flexibility to include satellite (reversibility) groups, bronchoalveolar lavage (BAL), lung burden (LB) for particles, neurologic tests, and additional clinical pathology and histopathological evaluations in order to better characterize the toxicity of a test chemical.
OECD TG 413: Subchronic Inhalation Toxicity: 90-day Study https://www.oecd-ilibrary.org/environment/test-no-413-subchronic-inhalation-toxicity-90-day-study_9789264070806-en This revised Test Guideline 413 (TG 413) has been designed to fully characterize test article toxicity by the inhalation route following repeated exposure for a period of 90 days, and to provide data for quantitative inhalation risk assessments. It was updated in 2017 to enable the testing and characterisation of effects of nanomaterials tested. Groups of at least 10 male and 10 female rodents are exposed 6 hours per day for 90 days to a) the test chemical at three or more concentration levels, b) filtered air (negative control), and/or c) the vehicle (vehicle control). Animals are generally exposed 5 days per week but exposure for 7 days per week is also allowed. Males and females are always tested, but they may be exposed at different concentration levels if it is known that one sex is more susceptible to a given test chemical. The results of the study include measurement and daily and detailed observations (haematology and clinical chemistry), as well as ophthalmology, gross pathology, organ weights, and histopathology. This Test Guideline allows the flexibility to include satellite (reversibility) groups, interim sacrifices, bronchoalveolar lavage (BAL), lung burden (LB) for particles, neurologic tests, and additional clinical pathology and histopathological evaluations in order to better characterize the toxicity of a test chemical.
