Bench Performance	Bench testing included:
	- Thermal safety test
	- Composite durability test
	- Color (imaging) performance
	- Photobiological Safety
	Device performance was assessed against design requirements, including process verification, design verification, and design validation. The device met all acceptance criteria.

2. Sample Size for Test Set and Data Provenance

The provided text describes various engineering and performance tests (reprocessing, biocompatibility, software V&V, electrical safety, EMC, and bench performance). These types of tests typically do not involve "test sets" in the clinical sense with human data. Instead, they involve testing the physical device, its materials, and its software against established technical and safety standards.

No "sample size" for a clinical test set is mentioned.
No "data provenance" (e.g., country of origin, retrospective/prospective) for clinical data is mentioned, as clinical data was not part of this submission's performance data section. The submission focuses on substantial equivalence based on technical characteristics and non-clinical performance data.

3. Number of Experts and Qualifications for Ground Truth Establishment

Not applicable. The performance data presented are based on engineering tests and adherence to recognized standards, not on expert-established ground truth from clinical cases.

4. Adjudication Method for Test Set

Not applicable. There is no clinical test set requiring adjudication in the provided performance data.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No multi-reader multi-case (MRMC) comparative effectiveness study is mentioned. This evaluation focuses on the safety and effectiveness of the device itself, rather than comparing human reader performance with and without AI assistance. The device is a videoscope, not an AI diagnostic tool.

6. Standalone (Algorithm Only) Performance Study

Not applicable. This device is a physical videoscope, not an algorithm, so a standalone algorithm-only performance study is not relevant.

7. Type of Ground Truth Used

The "ground truth" for the various performance tests is defined by:

Established national and international standards (e.g., FDA guidance documents, ISO 10993, ANSI/AAMI ES 60601-1, IEC 60601-1-2)
Manufacturer's design specifications and requirements.

8. Sample Size for Training Set

Not applicable. This device is a physical videoscope, not a machine learning model, so there is no concept of a "training set."

9. How Ground Truth for Training Set Was Established

Not applicable, as there is no training set mentioned or implied for this device.
