ISO certification is an official recognition that a company, organization, or process meets specific international standards set by the International Organization for Standardization (ISO). ISO is an independent, non-governmental international organization that develops and publishes standards to ensure quality, safety, efficiency, and consistency across industries worldwide.

What is an ISO-CERTIFICATION?

What does it involve?

ISO develops guidelines for how things should be done — whether it’s about:

managing product or service quality
handling environmental responsibilities
keeping information secure
protecting employee health and safety

When a company is ISO certified, it means an independent, authorized body has audited their systems or processes and confirmed they meet the requirements of a particular ISO standard.

Examples of Popular ISO Standards:

ISO 9001 → Quality management systems
ISO 14001 → Environmental management systems
ISO 17024 → Personal Certifications
ISO 27001 → Information security management
ISO 45001 → Occupational health and safety management

How does ISO certification work?

1. Preparation: The company aligns its processes and systems with the requirements of a specific ISO standard.

2. Audit: An independent certification body conducts an audit to assess compliance.

3. Certification: If the audit is successful, the company receives the ISO certificate, usually valid for 3 years, with annual surveillance audits to maintain it.

Why do companies get ISO certified?

Boost customer confidence and trust
Improve operational efficiency
Open doors to new markets and business opportunities
Meet legal or contractual requirements
Demonstrate commitment to continuous improvement

What is a National Accreditation Body (NAB)?

A National Accreditation Body is an official organization appointed by a country’s government to oversee and authorize certification bodies (the organizations that issue ISO certificates).

In short:
They check the checkers.

Example:
In the UK, it’s UKAS (United Kingdom Accreditation Service).
In Germany, it’s DAkkS (Deutsche Akkreditierungsstelle).

Why do we need them?

Because trust is everything in certification systems. Here’s why national accreditation bodies are essential:

1. Ensure Certification Bodies Are Competent

They make sure that the certification bodies (like TÜV, SGS, DNV, etc.) are:

properly qualified
impartial and independent
following international accreditation standards like ISO/IEC 17021 for management system certification.

Without that, anyone could claim to be a certifier — and certificates would lose value.

2. Maintain International Recognition

Through accreditation bodies, certifications can be recognized globally under international agreements (like the IAF MLA — International Accreditation Forum Multilateral Recognition Arrangement).
This ensures, for example, that a company’s ISO 9001 certificate from Germany is trusted in Canada, Japan, or Brazil.

3. Protect Consumers and Businesses

Accreditation ensures that certifications are reliable and not just marketing badges. It helps businesses and customers trust that the company holding a certificate truly meets those standards.

4. Prevent Fraud and Low-Quality Certifiers

By controlling and regulating certification bodies, accreditation bodies help prevent:

fake certificates
low-quality audits
conflicts of interest

How It All Connects:

👉 ISO (International standards organization) creates the standards
👉 National Accreditation Bodies accredit certification bodies
👉 Certification Bodies audit and certify companies
👉 Companies implement standards and get certified
