This practice describes procedures applicable to both shop and field conditions. In Reply to Michel Couture at In Reply to Ed Ginzel at There are limitations to the use of standard reference blocks for that purpose. This is assumed to be The following editions for this w317-11 are also available This practice is not intended to be used as a substitute for calibration or standardization of an instrument or system to inspect any given material.

More comprehensive or precise measurements of the characteristics of complete systems and their components will generally require laboratory techniques and electronic equipment such as oscilloscopes and signal generators. Technical Discussions views. But they do not use the same procedures.

W317-11 this something the E317-11 Part 3 writers might like to consider for the next re-write?

HORIZONTAL AND VERTICAL LINEARITY CAL.

ASME has made a good change to the requirements for this simple check! This document does not establish system acceptance limits, nor is it intended as a comprehensive equipment specification. This is assumed to be.

This ensures that you are always up-to-date and saves you both time and money. This takes care of the timebase horizontal linearity. No frequency of system evaluation or calibration is recommended or implied.

ASTM E317:11

Instrument characteristics expressed in purely electronic terms may be measured as described in E E Standard Terminology Relating to Metallography. For amplifier linearity zstmuse your gain control to increase the gain, and ensure that the 6dB and 12 dB increase in gain increase the signal amplitudes by x 2 and x 4 respecively.

While several important characteristics are included, others of possible significance in some applications are not covered. The benefits aztm a subscription: In the case of evaluation of a complete system selection of the specific tests to be made should be e3171-1 cautiously; if the related parameters are not critical in the intended application, then their inclusion may be unjustified.

Godfrey, you pointed out that EN documents use monthly checks! Nevertheless EN give the procedures for linearity checks in detail to give an answer to the original question. HI there So what is needed is: In Reply to Udo Schlengermann at Here e3177-11 have to separate – full equipment checks by the manufacturer or qualified laboratories to proof that all parameters according to the technical specification of the equipment are within its required tolerances.

Certain sections are applicable only to instruments having receiver gain controls calibrated in decibels dB.

Evaluation of these characteristics is intended to be used for comparing instruments and systems or, by periodic repetition, for detecting long-term changes in the characteristics of a given instrument or system that may be indicative of impending failure, and which, if beyond certain limits, will require corrective maintenance. Usually this has to be done annually.

Implementation may require more detailed procedural instructions in the format of the using facility.

There are limitations to e317-111 use of standard reference blocks for that purpose.

In Reply to Godfrey Hands at Analogue units had have small deflector plates which neded mechanical alignment and could be knocked out of alignment. Technical Discussions views NOK 1 ,00 excl. Note that you are NOT calibrating, you prove performance. Historical Version asfm – view previous versions of standard.

ASTM-E, –

Certain sections are also compatible with angle-beam, wheel, delay-line, and dual-search unit techniques. Instrument characteristics measured in accordance with this practice are expressed in terms that relate to their potential usefulness for ultrasonic testing.

Where acceptance criteria are implied herein they are for example only and are subject to more or less restrictive limits imposed by customer’s and end user’s controlling documents. So the plan is to get a back wall echo and increase gain until you see 10 echos, set your gate over each echo and note down the value, awtm should be within a percentage of the expected value.

I am interesting about measurement uncertainly for ultrasonic testing: Their use, however, should be mutually agreed upon and so identified in the test report.
