What is ISO/IEC Guide 99? A Free PDF Guide to the Basic and General Concepts of Metrology



In today's financially stressed environment we are all looking to minimize expenditures and yet, as metrologists, we also need to have ready-access to standards that are relevant to our work. While some standards-setting bodies make their documents freely available, this is seldom the case for ISO publications.

However, the good news is that the International Organization of Legal Metrology (OIML) is one of the standards bodies that offers its publications for free and they have the latest editions of the guides mentioned above, although published under an OIML standard identity.


Originally posted as a comment, here is a link to what appears to be a draft of the former mentioned standard, the ANSI C standard. It is my understanding that the drafts can be viewed for free, as @pmg has noted as well.

The International Organization for Standardization (ISO) has published ISO 17034:2016 on the general requirements for the competence of reference material producers (RMPs). Previously, these requirements were addressed in ISO Guide 34:2009, originally developed by the ISO Committee on Reference Materials (ISO/REMCO). The need for an International Standard was triggered as several accreditation bodies could not accredit to a guide, at all, while in other countries ISO Guide 34 could only serve as accreditation standard in combination with ISO/IEC 17025. For the transformation into a conformity assessment standard of the ISO/IEC 17000 series, the ISO Committee on Conformity assessment (ISO/CASCO) and ISO/REMCO joined forces. A Joint Working Group, formed by experts and stakeholders from both committees, finalised the transformation within 2 years. During the transformation, the structure of ISO 17034 has been aligned with other ISO/IEC 17000 series standards and the content of ISO 17034 has been harmonised with the recent editions of other relevant ISO Guides. Requirements for the production of reference materials (RMs) were elaborated on more clearly in the new standard, specifying the requirements for (non-certified) reference materials and the additional requirements for certified reference materials. The new International Standard ISO 17034:2016 supersedes ISO Guide 34:2009.


Previously minimum requirements for the production of reference materials (RMs) were contained in ISO Guide 34:2009 [1]. This document was developed by the International Organization for Standardization (ISO) Committee on Reference Materials (ISO/REMCO) and has been used by accreditation bodies for the third-party assessment of reference material producers (RMPs). The fact that the document was issued as a guide rather than a standard is based on ISO internal rules: ISO/REMCO is not allowed to issue standards, hence a guide, that was largely indistinguishable from a standard, was published [2]. The official status as guide, however, hindered its international harmonised acceptance and in some countries the application for third-party assessment without combining it with another International Standard. Therefore, ISO/REMCO decided in 2014 to transform ISO Guide 34 also formally into a standard and approached the Technical Management Board of ISO (ISO/TMB) with this request. Following the advice of ISO/TMB, a Joint Working Group was formed between the ISO Committee on Conformity assessment (ISO/CASCO) and ISO/REMCO with the ambitious goal to complete the transformation within 2 years.


In the European Union (EU), legislation sets out the requirements for accreditation and market surveillance and Regulation (EC) No 765/2008 demands that accreditation has to be based on international harmonised standards. Accreditation towards a guide was therefore only accepted during a transition period and would not be possible in the long term.


The general requirements contain a new clause regarding impartiality. It refers to the absence of a conflict of interest and is equivalent to the requirement that RMP staff should be free from financial pressure.
