The indications given are in no way intended to serve as a rule, neither for the mechanicaltesting conditions nor for thechoice of the non-destructive testing method to be applied. It will be the responsibility ofthe issuer of Quality Sheets QS to clearly complete those sheets, so as to define without ambiguity the place of examination and consequently the state of advancement required for the various controls prescribed. These criteria only apply to 4ndications to be confirmed, according to the present specification.

For this third edition, it gathers 3 Founders, 3 Designers, from Europe and North America and 1 Independent control organization as well as several technical cousultants. Magnetization mwst be maintained for a while after theliquid has been applied, so that the indications can stabilize and inOrder not to alter the already formed indications.

For Spot check inspections the following regulation will be applied: Scratching, hammering, shot blasting which may dull the Casting surface and thus hinder the penetration the of dye, the dye penetrantinspection should be preceded by a grinding of the surfaces to be inspected. Steffen said … [Read more The excessofpenetrant will be washedofand the Part dried.

Tim Van Berkel, from Australia, came in second in 3hr 55min 8sec, ahead of his fellow countryman Luke Mc Kenzie, with a time in 3hr 59min 18sec.

While maintainingthe magnetization, the excess ofpowder should be blown off carefully so as to leave only the indications created by the discontinuities.


As a reference, the above example contains 6 indications, all taken into consideration. Alongside the Ironman For calibrations only the distances between multiple echoes or between two echoes corresponding to distant reflectors of aknown value may be used and not xch distance between the pulse transmission and the first echo. The race, the biggest international triathlon event ever held in Vietnam, has attracted more than 1, … [Read more The concentration of liquid inks in magnetic powder is the one prescribed by the supplier.

The event’s organisers, the Sunrise Events Company, said in a press conference yesterday that ccb than 1, athletes including 25 professionals from 55 countries and territories will compete in the event. Its purpose is to detect possible internal defects in the parts, to designate the indications and to define the acceptance criteria.

The Quality sheets should be part of: The surfaces to be inspected on steel Castings must be such that the couplants between the probe and the part will not have a significant influence on the sensitivity of the examination.

This document is available in the following versions: The outline ofthe defect defines the surface S of this defect; the length of the defect is the largest dimensionof the whole defect. Definitions D Height of the maximum echo on thedefect after return to the calibrated amplification.

Lighting should be higher than Lux. The range is determined according to the – 6 dB method See 3 1. The eddy currentsmaintain the magnetic fluxon the cch slightly sub-surface discontinuities or discontinuities connected to the surface are detected very well regardless of the shape of the part.

Indeed, the quality level required involves adefinite manufacturing routine and Special precautions to be taken by the Founder, the Manufacturer or the Designer. For certain highly stressedareas the Designer may specify more severe criteria.

Thick coats of developer are unacceptable.

The demarcation between superficial and median areas is not always clearly defined when the Casting is of complex shape. The adjustment of sensitivity is obtained from the reference echo which is broughtto the screen of the ultrasonic apparatusto a given reference height. The total surface thus taken into accont is of 6.


Please ask for a confirmation of ccg amount required by email before sending any payment, by contacting jhecker uol. June CCH The third edition adapted: The currents supplied may be: It may howeverbe applied at earlier Stages, especially for theinspection of excavations. These devices must be verified periodically in Dch to make Sure that they can lift a ferritic mass of 4.

These adjustments are carried out simultaneously, the amplification threshold being brought back to the minimum. These devices and their instrumentation, if any, must be verified periodically using modalities defined by the User. In this case each party will have to be aware of several Quality Sheets produced.

Beyondthese limits, the efficiency of the products and of the process must be proved at the temperature at which the inspection is intended to be carried out. The extent of defect is expressed as a percentage ofthe reference amplitude. Sorry, your blog cannot share posts by email. This heat treatment may only be omitted with the agreement of the Designer See 1.

The heat and high humidity became a stiff challenge during the last four kilometres,” Van Berkel told the press after the race. The repartition of repaircosts may, for instance, be fixed on the basis of one of the criteria mentioned hereafter: Table 1 The surfaces shall be prepared according to acceptance criteria.


Every apparatus must havea labe1 indicating the date of calibration validity. The normal longitudinal probe is manually displaced on the surface ofthe part to be examined.

He said previous champions France’s Cyril Viennot and Switzerland’s Caroline Steffen will return to defend their titles.
