Second-party Conformity Assessment:

Conformity Assessment that is performed or required by a person or organization that has a user interest in the object (e.g. the procurer, purchaser or user).


A recognized unit of comparison by which the correctness of others can be determined. A standard may also be defined as a set of characteristics or qualities that describes features of a product, process, or service. According to the World Trade Organization Technical Barriers to Trade (WTO / TBT) Agreement, Annex 1, a standard is “a document, established by consensus, that provides rules, guidelines, or characteristics for activities or their results” or “a document that provides, for common and repeated use, rules, guidelines or characteristics for products or related process and production methods, with which compliance is not mandatory.”

Standards Developing Organizations (SDOs):

SDOs include professional societies, industry and trade associations and membership organizations that develop standards within their area of expertise. They may develop standards with their own members or in cooperation with other SDOs and interested parties. SDOs in the United States may choose to develop standards that are submitted to ANSI for approval as American National Standards (ANS). They may also develop standards outside the ANSI accreditation and approval process.

Suppliers’ Declaration of Conformity (SDoC):

Procedure by which a first party or supplier conveys assurance that the object of conformity fulfills specified requirements.


Systematic iteration of conformity assessment activities as a basis for maintaining the validity of the statement of conformity.

Technical Regulation:

According to the WTO / TBT Agreement, a technical regulation is “a document that provides technical requirements, either directly or by referring to or incorporating the content of a standard, technical specification, or code of practice” or “a document that lays down product characteristics or their related processes and production methods, including the applicable administrative provisions, with which compliance is mandatory.”
