Measurement Uncertainty in NDT

Hello,

I am interested in knowing the methodlogy for calculating the uncertainty in different Techniques of NDT to meet the requirements of ISO 17025, the standard for " Quality Systems for Testing laboratories ". Are there any suggestions on any guidelines ?

Thank You.

S S Ananthan

Re: Measurement Uncertainty in NDT
Hi

I posted something on Probability of detection on this forum some time ago. Two publications were recommeneded as a result.

Have fun

Wang

There are two publications I work from regarding PODs.
The first is the DOD/FAA pub "Reliability Assessment at Airline Inspection Facilities, V1: A Generic Protocol for Inspection Reliabilty Experiemnts", 1992.
The second publication is the DOD Hanbook "Nondestructive Evaluation System Reliability Assessment MIL-HNBK-1823, 30 Aprol 1999.
You may find the "format" you are looking for in these very informative publications.

Re: Measurement Uncertainty in NDT
Hopefully this doesn't sound too self-serving, but NTIAC sells an NDE Capabilities Data Book sponsored by the FAA that has among other things over 400 POD curves and presents guidelines on how to meet critical flaw detection requirements and demonstrating NDE process capabilities. For more information on the book, visit http://www.ntiac.com/pubs/databk3.html or our main page at http://www.ntiac.com.

Hope this helps,
Chris

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
...
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.

...
nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?

TOPAZ® 64: Fully Integrated Portable 64 Channel PAUT Instrument with FMC & TFM

Introducing TOPAZ64, the industry’s most intelligent fully integrated, portable 64-channel phased
...
array ultrasound (UT) instrument. TOPAZ64 combines code-compliant phased array UT with the industry’s most advanced full matrix capture (FMC) and total focusing method (TFM) capabilities. Featuring the highest acquisition frequency in its class, high resolution FMC and a 12” multi-touchscreen, users can easily visualize even the smallest flaws. TOPAZ64 can generate a bipolar pulse that provides more acoustic energy versus previous models for punching through thick components. The result is a portable tool that delivers increased inspection coverage, more accurate signals, and the ability to handle all UT inspections in one package. TOPAZ64 is ideal for challenging applications in transportation, oil and gas, manufacturing and power generation.
