## The Lifecycle of Pharmaceutical Equipment Qualification
Equipment qualification is the documented verification that pharmaceutical machinery is installed correctly, operates according to design intent, and consistently produces product meeting pre-determined quality specifications.
This guide provides a practical overview of the four standard qualification phases according to **GAMP 5** and **WHO Technical Report Series No. 961**.

## 1. Design Qualification (DQ)
**Objective:** Confirm that the equipment specification meets the User Requirements Specification (URS) and cGMP standards prior to fabrication.
* **Key Deliverables:** Functional Design Specification (FDS), Software Design Specification (SDS), Materials of Construction (MOC) review, and cleanroom dimensional layout sign-offs.

## 2. Installation Qualification (IQ)
**Objective:** Verify that the equipment, utilities, piping, and instrumentation are installed in accordance with engineering drawings and manufacturer specifications.
* **Mandatory Checklist:**
- [x] Physical inspection of AISI 316L contact parts and Ra surface finish verification.
- [x] Electrical wiring verification, phase rotation, and earthing resistance measurements (< 1.0 Ohm).
- [x] Calibration certificates for all temperature, pressure, vacuum, and speed transducers.
- [x] Verification of non-contact components (AISI 304) and food-grade lubricant certifications (NSF H1).

## 3. Operational Qualification (OQ)
**Objective:** Document that the equipment operates within established operational ranges under challenge conditions.
* **Key Test Scripts:**
- **Emergency Stop & Interlock Testing:** Verifying that opening guard doors immediately cuts power to rotating components within < 0.5 seconds.
- **Speed Range Capability:** Running machine unloaded across minimum, nominal, and maximum RPM ranges.
- **21 CFR Part 11 Testing:** User privilege separation, password aging, automatic session timeout, and non-editable audit trail verification.

## 4. Performance Qualification (PQ)
**Objective:** Demonstrate that the equipment performs consistently under routine commercial production conditions using placebo or active product batches.
* **Key Criteria:** Uniformity of dosage units (UDU), tablet dissolution profile consistency, yield verification (> 99.0%), and continuous temperature/vibration stability over three consecutive commercial batches.
