ISO 20252:2019

Overview

ISO 20252:2019 is the international standard for market, opinion and social research, including insights and data analytics. It defines a common vocabulary and specifies service requirements for service providers conducting research projects. The standard sets a mandatory core framework (Clause 4) and a set of normative annexes addressing specific research methodologies. Non-research activities such as direct marketing are explicitly outside its scope.

Key Topics

ISO 20252:2019 addresses both terminology and operational requirements. Major technical topics and requirements include:

• Vocabulary and definitions for research terms (access panels, sampling, CAI, anonymize, etc.), ensuring consistent language across projects and vendors.
• Core service requirements (Clause 4) covering the research business framework, including:
  • Statement of Applicability (SoA) and attestation requirements
  • Confidentiality, documentation and records management
  • Personnel responsibilities and performance management
  • Information security risk framework, information handling and controls
  • Subcontracting rules and management of subcontracted project work
  • Project planning, delivery, client relationship management and reporting
  • Management review, continual improvement and internal audits
  • Compliance with legal requirements
• Normative annexes (A–F) tailored to methodological areas:
  • Annex A: Sampling (including access panels)
  • Annex B: Fieldwork
  • Annex C: Physical observation
  • Annex D: Digital observation
  • Annex E: Self-completion
  • Annex F: Data management and processing
• Data quality and processing topics such as data cleaning, de-duplication, automated coding and data editing.

Applications

ISO 20252:2019 is used to:

• Standardize processes for market research agencies, insights teams, and social research organisations.
• Demonstrate consistent service delivery and data quality to clients and stakeholders.
• Guide procurement and contracting of research services, including the use of online access panels and digital observation methods.
• Support compliance with data handling, confidentiality and information security expectations in research and analytics projects.
• Provide a basis for audits and attestation of research service providers.

Who uses it

• Market research agencies and insights consultancies
• In-house research and analytics teams (brands, NGOs, public sector)
• Panel providers and fieldwork companies
• Certification bodies, auditors and procurement teams seeking conformity evidence

Related standards

• ISO 20252:2019 incorporates the technical scope of ISO 26362:2009 (access panels) which has been withdrawn and merged into this edition.
• Reference to ISO/IEC directives is noted for document preparation and maintenance.

ISO 20252 is a practical tool for improving transparency, consistency and trust in market, opinion and social research and in data analytics services.
