Evidence Boundary
Test methods are not interchangeable
The supplied manual lists ISO 9950, JB/T 7951-2004, JB/T 7951-1999 and SH/T 0220. ISO 9950 is publicly scoped to industrial quenching oils using a nickel-alloy probe tested without relative motion. Aqueous polymer media require an applicable method, probe and relative motion condition; a blanket “ISO 9950 compliant” statement is not sufficient.
Technical data boundary
Web values and curves apply only to the stated sample, probe, method and condition. They are not a guarantee of microstructure, hardness, distortion or crack-free results for a specific workpiece.
Validation
What makes a curve auditable
Identify sample
Record product, batch, service age, concentration or condition.
Fix the method
Record standard, probe material/size, heating condition and calibration.
Record the bath
State bath temperature, relative-motion condition or parameter and sampling method.
Keep raw data
Retain temperature-time, rate-temperature, characteristic points and the original measurement file.
FAQ
Technical questions
Answers are bounded by the material, workpiece, equipment and stated test conditions.
Can ISO 9950 be used as a blanket method for aqueous polymer media?
No. ISO 9950 is scoped to industrial quenching oils with a nickel-alloy probe tested without relative motion. Aqueous polymer media require an applicable method, probe and relative motion condition.
What must accompany a cooling curve?
Identify the sample and batch, method, probe material and size, heating and calibration, bath temperature, concentration or condition, relative motion and the original measurement file.
