Revision

Definition

A revision is an updated version of a document that incorporates changes, corrections, or additions while maintaining a clear record of what changed and why.

Overview

Document revisions are a fundamental part of quality systems. Each revision is tracked with a unique number or date, and a revision history is maintained to log what changed, when, and by whom.

Technical Explanation

Revision Numbering: - Sequential: 1.0, 1.1, 2.0 (major.minor) - Date-based: 2026-07-01, 2026-07-18 - Code-based: A, B, C, or Rev 01, Rev 02

Revision Triggers: - Specification changes - Method updates (new HPLC method, improved MS parameters) - Regulatory requirements - Error corrections - Product changes (new salt form, new packaging)

Revision History Section: Each document should include a revision history table: | Rev | Date | Description | Author | |---|---|---|---|

Importance in Peptide Documentation

Always use the current revision of a document. Revisions to TDS, COA, or SDS documents may reflect important changes in specifications or safety information that affect experimental design or handling procedures.
