Corrosion Rating by Eye Has Always Been a Dispute Waiting to Happen
Corrosion testing per ASTM D665 and NACE TM0172 has always had the same weak point: the final rating. Whether an inhibited mineral oil passes or fails, whether a pipeline cargo is safe for transport — these decisions have historically come down to one operator looking at a corroded steel spindle and making a judgement call. Different operators. Different results. Disputes between suppliers and receivers that cost time, money, and credibility.
The AD Systems CB10 and CT10 solve this end to end. The CB10 is a fully automated corrosion bath — it runs ASTM D665 and NACE TM0172 tests on two specimens simultaneously with precise, programmable control of temperature, stirring speed, water injection, and test timing. No manual intervention from start to finish. When the test ends, the CB10 lifts the specimen automatically and presents it for rating.
The CT10 takes over from there. It images the entire corroded surface of the specimen using a CCD camera and homogeneous lighting, calculates the exact percentage of corroded area, and converts it automatically to the selected method’s rating — NACE TM0172 grades A through E, or D665 light/moderate/severe. A fully documented, traceable test report is ready in under five minutes. No subjectivity. No disputes.
What the CB10 & CT10 Deliver in Your Lab
Complete, Integrated Corrosion Testing System
The CB10 and CT10 are designed to work together as a single workflow. The CB10 runs the oxidation bath test. The CT10 reads and rates the specimen. Together they replace the entire manual corrosion testing process — preparation, timing, and rating — with a fully automated, fully documented system.
Two Independent Test Positions — Run Simultaneously
The CB10 runs two tests at the same time in fully independent positions. Specimen insertion, water injection, temperature, and timing are individually controlled per position. Labs that previously ran tests sequentially now double throughput with no additional operator time.
Fully Automated Bath Operation
Once the operator loads the sample and initiates the test, the CB10 handles everything: heating, stirring, water injection, test timing, and automatic specimen lift at end of test. The entire procedure runs unattended. Direct drive low-torque motors stop automatically if anything contacts the stirrer shaft — a built-in safety step that protects both operators and specimens.
Objective, Quantitative Corrosion Rating — CT10
The CT10 eliminates the subjectivity that has always undermined manual corrosion rating. A CCD camera and homogeneous lighting system image the entire specimen surface. Software calculates the exact percentage of corroded area to 0.01% resolution and converts it to the applicable rating scale. The same specimen, measured by any operator, on any day, produces the same result.
Automatic Specimen Diameter Verification — CT10
Before rating, the CT10 automatically measures the spindle diameter and verifies it falls within method tolerances. This step is often skipped in manual testing — the CT10 makes it automatic, protecting result validity and ensuring method conformance is documented in every report.
PT100 with Embedded Calibration Data — CB10
Both PT100 temperature sensors in the CB10 come with embedded calibration data. Temperature is controlled to ±1°C across the full programmable range up to 80°C. No external calibration reference is required — the calibration data lives in the instrument and travels with it.
ASTM Method Compliance
Standard Test Method for Rust-Preventing Characteristics of Inhibited Mineral Oil in the Presence of Water
Tests the ability of inhibited mineral oils to prevent corrosion of ferrous metals when water is present. Used for turbine oils, circulating oils, and compressor oils. The CB10 runs the oxidation bath per D665 procedure A and B; the CT10 rates the result as light, moderate, or severe.
Determination of Corrosiveness of Pipeline Cargoes in the Presence of Water
Used to determine the corrosiveness of petroleum products — gasolines and other distillates — before pipeline transportation. The CB10 controls the test conditions; the CT10 rates the spindle as A, B++, B+, B, C, D, or E. Proven CT10 correlation with NACE visual rating confirmed by comparative study.
Standard Test Method for Measurement of Corrosion Inhibition Using Accelerated Iron Corrosion in Petroleum Products
CT10 supported. Used for evaluating corrosion inhibitors in petroleum products, particularly for pipelines and tankers. The CT10's quantitative imaging replaces manual visual assessment for this method.

Who Uses the CB10 & CT10
Petroleum Refinery & Lubricant QC Labs
Product release testing for turbine oils, circulating oils, compressor oils, and hydraulic fluids per ASTM D665. The CB10 runs the rust prevention test; the CT10 delivers an objective, documented rating that holds up to customer scrutiny and audit.
Fuel Pipeline & Terminal Operations
Corrosiveness testing of petroleum pipeline cargoes — gasolines, distillates — per NACE TM0172 before transportation. The CB10 and CT10 system produces NACE ratings that are defensible, reproducible, and eliminate disputes between shipper and receiver.
Lubricant & Additive Development Labs
Development and validation of corrosion inhibitor additive packages for mineral oils and petroleum products. The CT10's 0.01% resolution and fully quantitative output gives formulation chemists data that visual rating cannot provide.

Frequently Asked
Questions
What lubricant lab managers, pipeline QC teams, and petroleum testing professionals ask most often about the AD Systems CB10 and CT10.
Do I need both the CB10 and CT10, or can I use them separately?
They can be used separately. The CB10 runs the corrosion bath test and outputs a conditioned specimen — you can then rate that specimen visually per the standard method if you choose. The CT10 can also rate specimens prepared in any ASTM D665 or NACE TM0172 compliant bath, not just the CB10. That said, the two instruments are designed to work together as a complete system, and the combination delivers the biggest improvement in speed, objectivity, and traceability. Kevin can advise on whether one or both instruments make sense for your specific workflow.
How does the CT10 compare to visual rating?
The CT10 was developed specifically because visual rating is subjective, operator-dependent, and a known source of disputes between product suppliers and receivers. The CT10 images the entire specimen surface, calculates corroded area to 0.01% resolution, and converts it to the method rating scale automatically. A comparative study confirmed strong correlation between CT10 results and NACE TM0172 visual rating — with the key difference that the CT10 result is the same regardless of which operator runs the test or when.
What corrosion methods do the CB10 and CT10 support?
The CB10 supports ASTM D665, D4378, NACE TM0172, IP135, ISO 7120, GOST 19199, and JIS K2510. The CT10 supports ASTM D665, D7548, NACE TM0172, IP 135, ISO 7120, and JIS K2510. Both instruments are delivered ready for operation per the selected standard — no additional configuration required.
Can the CB10 run two different test methods simultaneously?
Yes. Tests can be run unattended simultaneously or independently on the two positions.
How long does a complete test cycle take with the CB10 and CT10 together?
The CB10 test duration is set by the method — ASTM D665 requires a minimum of 24 hours. The CB10 runs this unattended. At the end of the test it automatically lifts the specimen for rating. The CT10 then measures and produces a fully rated, documented report in under five minutes. Total active operator time across the entire workflow: approximately 10 minutes.
What does the CT10 report include?
Every CT10 report includes: the full-colour image of the specimen surface, the binary image used for corrosion area calculation, the exact corrosion percentage, the method rating (NACE or D665), the specimen diameter (automatically measured and verified), test conditions (standard, temperature, duration), operator ID, sample ID, date and time, and software version. All reports are stored in the database and can be exported via USB or LAN.
