An ISO/IEC 17025 quality manual is the top-level document in a laboratory’s management system — it defines policy, establishes authority, and maps the procedures that govern how the lab operates. For accreditation assessors, it is often the first document requested and sets the tone for the entire assessment. A well-written quality manual doesn’t need to be long, but it does need to be complete.
This article explains what an ISO/IEC 17025 quality manual must contain, how it is typically structured, and what distinguishes a laboratory quality manual from the generic quality manuals that work well for ISO 9001.
What Is a Quality Manual?
A quality manual is a controlled document that describes the laboratory’s management system at a policy and overview level. It states what the lab does and why — procedures and work instructions explain how.
The quality manual typically:
- States the lab’s quality policy
- Describes the scope of laboratory activities covered by the management system
- Defines the organizational structure and key roles
- References the procedures that implement each requirement of the standard
- Demonstrates how the lab addresses each element of ISO/IEC 17025
While ISO/IEC 17025 does not mandate a single document called a “quality manual” by name, the requirements of Clause 8 (management system) collectively require the content that a quality manual traditionally contains. Most accreditation bodies expect to see it as a standalone controlled document.
Core Contents of an ISO/IEC 17025 Quality Manual
1. Scope and Purpose
The opening section defines the boundaries of the management system:
- What laboratory activities are covered (testing, calibration, sampling, or a combination)
- Which physical locations, branches, or mobile units are included
- Which analytes, measurands, or test types fall within the accredited scope
- Any activities that are explicitly excluded and why
A clearly written scope prevents the common problem of a quality manual that appears to cover everything but actually doesn’t address large portions of the lab’s real work.
2. Quality Policy Statement
The quality policy is a brief declaration signed by top management that commits the lab to:
- Operating with integrity and impartiality
- Maintaining competence in its defined scope
- Continually improving the management system
- Meeting the requirements of ISO/IEC 17025 and the expectations of clients and accreditation bodies
The policy should be specific enough to mean something. Generic statements like “we are committed to quality” satisfy no one. A policy that references accreditation, client satisfaction, measurement validity, and impartiality is both meaningful and auditable.
3. Organizational Structure and Authority
This section documents:
- The organizational chart showing management, technical, and quality roles
- Lines of reporting and functional responsibility
- Who is authorized to issue test reports and calibration certificates
- The role of the technical manager (or equivalent), quality manager, and laboratory director
- How the lab manages impartiality at an organizational level
For labs that are part of a larger organization, this section must also explain how the laboratory function maintains operational independence from other parts of the business when conflicts of interest could arise.
4. Document and Records Control
The quality manual describes the system for managing controlled documents:
- How documents are created, reviewed, approved, and issued
- How document versions are tracked and how obsolete versions are removed from use
- How records are identified, stored, protected, retained, and disposed of
- Retention periods for different record types (typically defined in a records control procedure referenced here)
This section needs to reflect actual practice. Auditors will pull a procedure and ask to see the record it requires — if the retention period in the manual says five years but the records are gone after two, that’s a nonconformity.
5. Personnel and Competency
The quality manual explains the lab’s approach to managing personnel competence, typically covering:
- How competency requirements are defined for each role
- The training and authorization process for new and existing staff
- How ongoing competence is monitored (performance review, proficiency testing participation, observation of work)
- How contract and temporary staff are managed
This section does not need to list every individual’s competencies — that belongs in personnel files. It describes the system by which competence is established and maintained.
6. Facilities, Equipment, and Metrological Traceability
A brief overview of:
- How environmental conditions are controlled and monitored
- How equipment is selected, identified, maintained, and calibrated
- How metrological traceability to SI units is established and maintained
- How equipment that is out of calibration or service is controlled
The detailed procedures are referenced here; the manual describes the policy and overall approach.
7. Method Selection, Validation, and Verification
The quality manual states the lab’s policy on methods:
- Criteria for selecting methods appropriate to client requirements
- The distinction between standard method verification (demonstrating the lab can achieve published performance characteristics in its environment) and non-standard method validation (demonstrating fitness for purpose through systematic performance characterization)
- How method changes and deviations are controlled
This section is often where ISO/IEC 17025 quality manuals diverge most sharply from ISO 9001 quality manuals. A generic quality manual has nothing equivalent — ISO 9001 does not require method validation in the laboratory sense.
8. Measurement Uncertainty
The manual states the lab’s policy on estimating and reporting measurement uncertainty. It references the procedure that defines how uncertainty budgets are developed and maintained. The policy should confirm that uncertainty is estimated for all methods within scope and reported on results unless the client has agreed otherwise or the method contains a fixed limit that already accounts for uncertainty.
9. Quality Control and Ensuring Validity of Results
This section describes the lab’s internal quality control program at a policy level:
- What types of QC checks are used (blanks, duplicates, spikes, reference materials, control charts)
- How proficiency testing participation is managed and results evaluated
- What triggers an investigation of data quality and what remediation steps apply
10. Complaints, Nonconformities, and Corrective Action
The manual describes the lab’s approach to:
- Receiving and evaluating client complaints
- Identifying nonconforming work and deciding whether previously issued results are affected
- Investigating root causes and implementing corrective actions
- Verifying that corrective actions were effective
11. Internal Audits and Management Review
The manual commits to:
- Conducting internal audits at planned intervals covering all elements of the standard
- Conducting management reviews at planned intervals, with defined inputs (audit results, PT performance, complaints, resource adequacy) and outputs (decisions and actions)
12. Reference to Supporting Procedures
The quality manual should include a document register or a cross-reference table mapping each clause of ISO/IEC 17025 to the procedure(s) that implement it. This helps auditors navigate the management system and helps laboratory staff find the right document quickly.
What a Quality Manual Is Not
A quality manual is not the same as:
- A procedure manual — procedures explain step-by-step how to perform specific activities. The quality manual references them but does not duplicate their content.
- A scope of accreditation — the formal scope document (issued by the accreditation body) lists the specific methods and measurement ranges the lab is approved for. The quality manual’s scope section supports but does not replace this.
- A marketing document — it is an internal controlled document, not a client-facing brochure. Copying text from a website into a quality manual and calling it a policy statement fools no one.
Getting Started
Writing a quality manual from scratch takes significant effort, particularly for labs unfamiliar with what accreditation bodies expect to see in each section. The ISO/IEC 17025 template kit includes a complete, editable quality manual pre-mapped to all clauses of the current standard, along with the full set of required procedures and forms that the manual references.
After your quality manual is in place, use our free ISO/IEC 17025 checklist to verify that all required elements are addressed before your accreditation assessment.
Note: A template quality manual is a starting point — it must be adapted to reflect your laboratory’s actual scope, structure, and practices before it can satisfy an accreditation body. Templates and guidance materials do not by themselves grant accreditation.
Frequently Asked Questions
How long should an ISO/IEC 17025 quality manual be? There is no prescribed length. Effective quality manuals for small to mid-sized laboratories typically run 20–50 pages. The goal is completeness and clarity, not volume. A 10-page manual that clearly maps every requirement and references well-written procedures can outperform a 100-page document full of copied standard text.
Does the quality manual need to be available to laboratory staff at all times? Yes. Document control requirements mean that the current, approved version must be accessible to all staff who need it. In practice, this means either a shared network location or a paper-controlled copy in the lab. Obsolete versions must be removed from circulation or clearly marked as superseded.
How often should the quality manual be reviewed and updated? At a minimum, the quality manual should be reviewed as part of the annual management review cycle. It should also be updated whenever the lab’s scope changes, when the standard is revised, or when an internal audit reveals that the manual no longer reflects actual practice.
Can we use an ISO 9001 quality manual as the basis for our ISO/IEC 17025 quality manual? You can use it as a starting point for the management system sections (document control, corrective action, internal audit, management review), but you will need to add all of the technical content specific to laboratory activities — method validation, measurement uncertainty, equipment calibration traceability, and so on. ISO 9001 quality manuals typically have no equivalent for these requirements.
Do we need a quality manual if we use the ISO 9001 option (Clause 8, Option B)? Under Option B, a certified ISO 9001 management system covers the management system clauses of ISO/IEC 17025. However, the lab still needs documented evidence addressing the technical clauses of the standard (resource requirements, process requirements), and most accreditation bodies still expect a document that ties these together in a laboratory-specific context.
