Overview

What is ISO Certification?

An ISO Certification is an international standard that confirms the quality, safety, efficiency and consistency of an organisation’s products, services or systems. Developed by the International Organization for Standardization (ISO), the certificate enables an organisation to demonstrate its commitment to excellence and continual improvement.

From new enterprises to well-established ones, an ISO certificate is a handy strategic tool for streamlining processes, fulfilling customer needs and enhancing market competitiveness. It is granted after intensive audits and assessments by external certification bodies, and proves that your organisation operates according to internationally accepted standards. This makes it easier to build trust with customers, partners and regulatory bodies.

The full form of ISO Certification is International Organization for Standardization Certification. ISO is itself a short name derived from the Greek word “isos”, meaning equal, which captures its spirit of consistent standards worldwide. Whether you are in manufacturing, software, healthcare or food services, the ISO standard gives you a single language to demonstrate world-class processes.

How it works

The certification process, step by step

With an experienced partner, the ISO certificate process becomes a smooth, trouble-free journey. There are also three types of audit you will encounter along the way.

Step-by-step procedure

Choose the standard
Identify the standard from the ISO certificate list that fits your need, for example ISO 9001 for quality or ISO 27001 for information security.
Application submission
Apply through an ISO registrar, giving brief details of your organisation’s operations and purpose.
Document review
Submit quality manuals, policy statements and process records so the certifying body can verify conformity with the standard.
Initial audit
A gap analysis or pre-assessment audit identifies areas of non-compliance before the official audit.
Action plan and on-site audit
Address the deficiencies, then undergo an official on-site audit. All major non-conformities must be resolved before the certificate is granted.

Types of audit in ISO

Internal audit
Conducted by trained internal staff or external advisors to check the system before certification.
Supplier audit
Ensures that your suppliers also meet the relevant ISO standards.
Certification audit
Performed by accredited ISO certificate bodies, leading to the grant of certification.

Documents required

PAN Card and Aadhar of the applicant
Passport-size photograph

Lifecycle
