Reference standard qualification process flowchart

What the reference standard qualification process is

Qualification comes before routine standard management. The template begins by defining the candidate's identity, source and intended use, because a reference standard cannot be assessed meaningfully when those three things are still assumptions. An incomplete definition stays on hold while the custodian or requester resolves the gap.

Once the evidence plan is in place, the chart distinguishes inadequate supporting information from an evaluation that does not support the defined use. Both negative routes remain in the qualification record, while an approved standard receives a controlled status and conditions for later management. Tailor the evidence, assessments and approval roles to the methods and standard types in your laboratory.

What this flowchart covers

In this template

• A candidate-definition decision for identity, source and intended use before a qualification plan is created.
• A hold-and-clarification loop for a candidate whose source or intended use is incomplete.
• Separate branches for unacceptable supporting information and for an unsuccessful planned evaluation.
• A documented qualification outcome that assigns controlled status or preserves an alternative need and follow-up.

When to use this template

• You are qualifying a new reference standard, replacement source or candidate for a defined analytical use.
• Teams need to show how technical evidence, physical assessment and an approval decision connect before a standard is entered into routine management.
• You want failed or held candidates to remain traceable instead of disappearing when an alternative is selected.

How it works

1. Bound the intended use

   State the analytical, control or other use being qualified and avoid treating a successful decision as permission for every possible method.

2. Plan evidence and assessment

   List the source, identity, technical and evaluation evidence the local procedure requires, plus the reviewers who assess it.

3. Carry decisions into management

   Define how an approved candidate receives controlled status and how a held, rejected or failed candidate is recorded for follow-up.

Frequently asked questions

What does a reference standard qualification process flowchart cover?

It covers defining identity, source and intended use, creating a qualification plan, reviewing supporting information, evaluating the standard, approving or restricting the outcome and recording conditions.

How is reference standard qualification different from management?

Qualification determines whether a proposed standard supports a defined use and under what conditions. Management covers the later routine lifecycle of an approved standard.

What should happen when a candidate reference standard fails evaluation?

Quarantine or otherwise control the candidate, document the facts and route it to the appropriate investigation or alternative-selection process. Criteria belong to the local qualification procedure.
