ISO/IEC 17025 Test Certificate Builder

Create controlled laboratory test certificates and inspection-style test records with result traceability, method details, sampling information, measurement uncertainty, conformity decisions, equipment, environmental conditions and technical authorisation.

Important: ISO/IEC 17025 applies to testing and calibration laboratories. Stand-alone inspection-body activities are normally assessed against ISO/IEC 17020. This app supports inspection observations that form part of a laboratory test report, but it does not by itself establish accreditation or authorise use of an accreditation symbol.

ISO/IEC 17025 Reporting Guidance

Practical prompts for complete, clear, unambiguous and objective reporting. Always verify contractual, regulatory, method-specific and accreditation-body requirements.

Guidance, not accreditation advice

Identity and control

Use a unique report number, page control, issue status, laboratory identity and location, customer identity, dates, method references and unambiguous identification of each item.

Scope and accreditation

State which results are within the accredited scope. Clearly identify externally provided results, unaccredited activities, deviations and customer-supplied information.

Results and units

Report the result, unit, method, location or specimen, relevant conditions and any qualifiers. Avoid excessive precision and unexplained abbreviations.

Measurement uncertainty

Report uncertainty where relevant to validity, customer instruction, method requirement or conformity assessment. State coverage factor or confidence basis where applicable.

Statements of conformity

Identify the specification, which results the statement applies to, and the decision rule used. Explain guard bands or risk treatment where they affect the decision.

Sampling

Where the laboratory sampled, record plan and method, date, location, environmental conditions, item identification and any deviation that could affect interpretation.

Opinions and interpretations

Only include them when authorised and clearly label them. State the basis used and keep them separate from raw test results.

Amendments

Issue amendments under controlled identification, reference the original report, describe the change and preserve the audit trail. Do not silently overwrite an issued certificate.

Professional writing

Write facts before conclusions.
Use consistent terminology and SI units.
State limitations and exceptions.
Make traceability easy to audit.
Avoid marketing claims and ambiguity.

Pre-issue Review Checklist

Items, specimens and locations are uniquely identified.

Method, revision, deviations and validation status are clear.

Equipment, standards and result records are traceable.

Uncertainty reporting is appropriate to the result and decision.

Conformity statements identify specification and decision rule.

Technical review, authorisation and issue controls are complete.
