If you run or manage a certification body, you’ve probably noticed how often the word “impartiality” comes up in audits. There’s a reason for that. Clause 5 of ISO/IEC 17021-1 isn’t just another compliance item—it’s the backbone of credibility for your entire certification process.
In my experience working with CBs preparing for accreditation, the challenge usually isn’t understanding what impartiality means; it’s proving it. Auditors want to see real, practical evidence that your team operates without bias—especially when commercial pressure comes into play.
By the end of this guide, you’ll know exactly how to interpret Clause 5, spot weak points in your impartiality framework, and strengthen your CB’s governance to stand up to any accreditation audit.
Understanding ISO/IEC 17021-1 Clause 5: General Requirements Explained
Clause 5 sets the tone for everything that follows in ISO/IEC 17021-1. It’s about how your CB operates at its core—ensuring that certification decisions are consistent, competent, and free from influence.
Here’s what that means in practice:
You must show that your certification process is independent, not swayed by sales targets or client relationships.
Your team’s decisions should be made solely on audit results, not client reputation or size.
Policies should clearly define how impartiality risks are identified, reviewed, and controlled.
Pro tip: Align every sub-clause of Clause 5 with one documented procedure or policy. That way, when the assessor asks, “Where is this covered?”, you can point directly to a file—no scrambling, no guessing.
Common pitfall: Many CBs treat Clause 5 like a “statement of values.” It’s not enough to say you’re impartial—you have to prove it through meeting minutes, impartiality reviews, and documented risk analyses.
The Principle of Impartiality – Core of Trust in Certification
Impartiality is the heart of trust between you and your clients. Without it, your certificate is just paper.
I once worked with a CB that nearly lost its accreditation because one of its auditors had previously worked as a consultant for a certified client. Even though the auditor didn’t mean to cross a line, the perception of bias was enough to trigger a nonconformity.
That’s how strict accreditation bodies are—and rightly so.
Here’s how to build genuine impartiality into your system:
Establish an Impartiality Committee with external representatives—industry experts, clients, even competitors if possible.
Review impartiality risks regularly, not just annually.
Keep detailed records of every decision and its rationale.
Pro tip: Rotate committee members every year. It keeps the group objective and prevents internal bias from building up.
Managing Conflicts of Interest under ISO/IEC 17021-1 Clause 5.2
Conflicts of interest are often subtle—they creep in through relationships, partnerships, or side activities that seem harmless at first. The key is early detection.
Step-by-step approach:
Create a risk register dedicated to impartiality.
Record every potential conflict: ownership links, consulting history, family ties, shared premises, or financial interests.
Assign each a risk rating (low, medium, high).
Define what actions you’ll take to mitigate it—like independent review or exclusion from certain decisions.
Pro tip: Train your sales and audit teams to recognize potential conflicts before proposals go out. It’s easier to prevent than explain later.
Common mistake: CBs often forget to update the register after new hires, partnerships, or service expansions. Outdated records are one of the fastest ways to get a finding during an audit.

Clause 5 also covers how your organization is structured. Auditors look closely at whether certification decisions are made independently of sales and audit functions.
One CB I assisted solved a long-standing impartiality issue by restructuring reporting lines: the sales department reported to operations, while certification decisions were handled by a completely separate director. That single change cleared three major findings at their next accreditation audit.
Checklist for your CB:
Separate decision-making from auditing and marketing.
Clearly define authority and responsibilities in your org chart.
Document governance procedures and review them annually.
Keep impartiality declarations signed by top management.
Pro tip: Even small CBs can show structural independence—use external decision reviewers if your team is too small.
Transparency & Public Confidence – Building Credibility through Openness
Transparency is what turns compliance into trust. Accreditation bodies expect CBs to make impartiality visible, not hidden behind confidentiality excuses.
Here’s how to do it effectively:
Publish your impartiality policy on your website.
Share a short annual summary of impartiality committee activities.
Show how complaints are handled and resolved.
Common mistake: Many CBs think keeping everything confidential protects them. But excessive secrecy can backfire—it looks like you’re hiding conflicts or client favoritism.
Pro tip: Be open about your impartiality measures, but never disclose confidential client data. The balance builds confidence.
Pro tip: Add “impartiality awareness” to your auditor training program. It keeps the concept alive in day-to-day decisions, not just paperwork.
Pitfall: Some CBs see impartiality as a “compliance checkbox.” When it’s treated like a value instead, your whole culture shifts—from defensive to genuinely ethical operations.

FAQs – ISO/IEC 17021-1 Clause 5 General Requirements & Impartiality
Q1: How often should we review impartiality risks? A: At least once a year—and whenever there’s a major organizational or business change.
Q2: Can our auditors provide ISO training to clients? A: Yes, but only if it’s clearly separated from certification activities and can’t influence decisions. Document everything.
Q3: What evidence do auditors expect for impartiality compliance? A: Your impartiality policy, risk register, committee minutes, signed declarations, and an up-to-date org chart showing role separation.
Embedding Impartiality as Your CB’s Competitive Edge
Clause 5 isn’t just about compliance—it’s about credibility. When your CB lives and breathes impartiality, you don’t just meet requirements; you attract trust from clients, regulators, and accreditation bodies.
After helping multiple CBs earn accreditation across ISO 9001, ISO 14001, and ISO 45001, I’ve seen one truth hold up: impartiality isn’t an obstacle—it’s your best marketing tool.
