This document is a 510(k) Premarket Notification from STERIS Corporation to the FDA regarding several Liquid Chemical Sterilant Processing Systems. It's important to understand that this document describes a sterilization device, not an AI/ML-driven diagnostic or image analysis device. Therefore, many of the requested criteria related to AI/ML performance (e.g., sample size for training/test sets, expert adjudication, MRMC studies, standalone algorithm performance, ground truth for training data) are not applicable to this type of medical device submission.
The acceptance criteria provided are for the functional and physical performance of a chemical sterilant processing system and its associated sterilant, not for an AI model's diagnostic accuracy.
Here's a breakdown of the requested information based on the provided document:
Device Description and Purpose:
The devices are the "SYSTEM 1E Liquid Chemical Sterilant Processing System," "SYSTEM 1 endo Liquid Chemical Sterilant Processing System, Model P6800," and "SYSTEM 1 endo Liquid Chemical Sterilant Processing System, Model P6900," along with the "S40 Sterilant Concentrate." These systems are intended for liquid chemical sterilization of cleaned, immersible, and reusable heat-sensitive medical devices (critical and semi-critical) in healthcare facilities. They utilize peracetic acid as the sterilant.
The submission is specifically for modifications to existing cleared devices (predicate K210737), primarily involving:
- Obsolescence and replacement of interface board and connector (for SYSTEM 1E)
- Obsolescence and replacement of silicone tubing (for all models)

2. Sample size used for the test set and the data provenance
The document does not specify exact sample sizes (e.g., number of units tested, number of cycles performed) for the functional, reliability, EMC/EMI, form and fit, physical properties, stability, or delivery tests. It simply states "Functional testing," "Reliability testing," etc., and confirms the Pass result.
Data provenance (e.g., country of origin, retrospective/prospective) is not mentioned as these were laboratory-based engineering and performance tests for a sterilization device, not clinical data for an AI/ML diagnostic.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This criterion is not applicable. The "ground truth" for this device relates to its ability to function as a sterilizer and its components meeting engineering specifications. This is established through predefined performance requirements (e.g., UL standards for electrical safety, physical property equivalence, stability of sterilant), not through expert consensus on medical images or diagnoses. Validation would be performed by engineers and quality control personnel according to established test protocols.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This criterion is not applicable. Adjudication methods like 2+1 are used for resolving disagreements among human readers or between AI and human reads in diagnostic studies. For a sterilization device, test results are typically objective (e.g., does it pass/fail a function test, does it meet a physical specification).
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
This criterion is not applicable. This is not an AI-assisted diagnostic device. No human readers or interpretations are involved in its primary function, which is sterilization.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This criterion is not applicable. This is not an algorithm, but a physical medical device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" in this context refers to the engineering and performance specifications for the device and its components. These include:
- Predefined functional requirements (e.g., device operation, sterilant delivery).
- Compliance with recognized electrical safety and electromagnetic compatibility (EMC/EMI) standards (e.g., UL 61010-1, UL 61010-2-040).
- Physical properties matching existing components.
- Chemical stability of the sterilant.
For the basic germicidal efficacy of the sterilant mentioned in the predicate device comparison (Tables 2 on pages 11-13, 22-23, and 32-34), the ground truth for microbial efficacy (e.g., "Meets efficacy requirements," "Solution is bactericidal") would be established through laboratory microbiological testing (e.g., AOAC Official Methods, EPA Viricidal Testing), which involves culturing specific microorganisms and observing their reduction or elimination after exposure to the sterilant. This is not an AI/ML-related ground truth.
8. The sample size for the training set
This criterion is not applicable. This is not an AI/ML device; there is no "training set."
9. How the ground truth for the training set was established
This criterion is not applicable. There is no AI/ML training set for this device. Ground truth for its performance is established through adherence to physical and chemical engineering specifications and established microbiological testing protocols.

2. Predicate Device
SYSTEM 1endo Liquid Chemical Sterilant Processing System, Model P6800, K210737
3. Description of Device
The SYSTEM 1 endo Liquid Chemical Sterilant Processing System is a liquid chemical sterilization system, utilizing peracetic acid to process totally immersible semi-critical medical devices and their accessories. The system consists of the SYSTEM 1 endo Processor and S40 Sterilant Concentrate, interchangeable Processing Trays/Containers, and Quick Connects. The current submission is provided to describe modifications for:
- Obsolescence and replacement of silicone tubing
- S40 Sterilant Concentrate design modification .
The SYSTEM 1 endo Processor is an automated. self-contained device that uses S40 Sterilant Concentrate to create and maintain the conditions necessary for liquid chemical sterilization in 6 minutes. Following processing, the liquid chemically sterilized articles are rinsed with 0.2 micron filtered potable water and are ready for use or may be prepared for storage. The processor, which is computer controlled and continually monitored, provides printed documentation of each cycle.
The SYSTEM 1 endo Processor uses only S40 Sterilant Concentrate. Upon loading the single-use cup, the active ingredient in S40 - peracetic acid - is combined with inert ingredients (builders) to form a use dilution which inhibits corrosion of metals, polymers and other materials.
The interchangeable processing trays/containers are made to accommodate a variety of semi-critical instrument types and models. Each container is designed to maintain instruments in position while specific SYSTEM 1 endo Quick Connects, if
{18}------------------------------------------------
required, facilitate delivery of the sterilant use-solution and rinse water to internal channels. Table 1 compares the proposed and predicate devices.
Intended Use 4.
The SYSTEM 1 endo Liquid Chemical Sterilant Processing System is intended for liquid chemical sterilization of cleaned, immersible, and reusable semi-critical medical devices and their accessories in healthcare facilities.
The SYSTEM 1 endo Processor dilutes the S40 Sterilant Concentrate to its use dilution (>1820 mg/L peracetic acid), liquid chemically sterilizes the load during a controlled 6-minute exposure at 45.5 to 55°C, and rinses the load with 0.2 micron filtered potable water.
The SYSTEM 1 endo Processor uses only S40 Sterilant Concentrate to liquid chemically sterilize medical devices.

2. Predicate Device
SYSTEM 1 endo Liquid Chemical Sterilant Processing System, Model P6900, K210737.
3. Description of Device
The SYSTEM 1 endo Liquid Chemical Sterilant Processing System, Model P6900 is a liquid chemical sterilization system, utilizing peracetic acid to process totally immersible semi-critical heat-sensitive medical devices and their accessories. The system consists of the SYSTEM 1 endo Processor and S40 Sterilant Concentrate, interchangeable Processing Trays/Containers, and Quick Connects. The current submission is provided to describe modifications for:
- Obsolescence and replacement of silicone tubing
- S40 Sterilant Concentrate design modification
The SYSTEM 1 endo Processor is an automated, self-contained device that uses S40 Sterilant Concentrate to create and maintain the conditions necessary for liquid chemical sterilization in 6 minutes. After LCS processing, the liquid chemically sterilized articles are rinsed with 0.2 micron filtered potable water and are ready for use or may be prepared for storage.
The SYSTEM 1 endo Processor uses only S40 Sterilant Concentrate. Upon loading the single-use cup, the active ingredient in S40 - peracetic acid - is combined with inert ingredients (builders) to form a use dilution which inhibits corrosion of metals, polymers and other materials.
The interchangeable processing trays/containers are made to accommodate a variety of semi-critical instrument types and models. Each container is designed to maintain instruments in position while specific SYSTEM 1 endo Quick Connects, if required, facilitate delivery of the sterilant use-solution and rinse water to internal channels. Tables 1 and 2 compare the proposed and predicate devices.
{28}------------------------------------------------
4. Indications for Use
The SYSTEM 1 endo Liquid Chemical Sterilant Processing System is intended for liquid chemical sterilization of cleaned, immersible, and reusable semi-critical heatsensitive medical devices and their accessories in healthcare facilities.
The SYSTEM 1 endo Processor automatically dilutes the S40 Sterilant Concentrate to its use dilution (> 1820 mg/L peracetic acid), liquid chemically sterilizes the load during a controlled 6-minute exposure at 45.5 to 60°C and rinses the load with 0.2 micron filtered water.
The SYSTEM 1 endo Processor uses only S40 Sterilant Concentrate to liquid chemically sterilize medical devices.
