Inspection location

The ECD is well suited as a selective detector for compounds with high electron affinity and limited linear response (dynamic range 104 with nitrogen). ECD detection is mainly used for analyses of chlorine-containing pesticides. Because of the presence of a radioactive source in this detector, it is subject to special regulations (e.g. inspections location and maintenance visits). [Pg.36]

The OPCW Health and Safety Office will consider the health and safety of all OPCW personnel in all working environments. This extends from hazardous inspection locations to administrative offices. The Health and Safety Office will implement a comprehensive OPCW Building safety plan. [Pg.302]

Visual inspection locate areas with concrete spalling, rust staining and delaminations. [Pg.978]

A Critical Vehicle Inspection Item violation(s) (OOS or othenwise) noted during a CVSA Level I Inspection that is successfully repaired on-site and re-inspected by the same inspector at the same inspection location will qualify for a CVSA decal as long as all previously noted Critical Vehicle Inspection Item violation(s) have been properly repaired. In such instances, only a re-Inspection of the repaired violation(s) shall be done with decal(s) being applied to the vehicle(s) and properly noted upon the original inspection. [Pg.564]

The 45° transducer was used to inspect side drilled holes, with their centres located 40 mm below the surface. Due to the coarse material structure the echoes from the holes were totally masked by clutter. An example of an ultrasonic response signal, emanating from a hole with a diameter of 8 mm, is shown in the left part of Figure 3. Scanning the surface above the 8 mm and 10 mm holes resulted in the B-scan image shown in the upper part of Figure 4. [Pg.92]

In service inspections of French nuclear Pressure Water Reactor (PWR) vessels are carried out automatically in complete immersion from the inside by means of ultrasonic focused probes working in the pulse echo mode. Concern has been expressed about the capabilities of performing non destructive evaluation of the Outer Surface Defects (OSD), i.e. defects located in the vicinity of the outer surface of the inspected components. OSD are insonified by both a "direct" field that passes through the inner surface (water/steel) of the component containing the defect and a "secondary" field reflected from the outer surface. Consequently, the Bscan images, containing the signatures of such defects, are complicated and their interpretation is a difficult task. [Pg.171]

AUQUR 4.2 revealed a number of small-size defects with the height of about 2 mm did not detected by manual inspection. These flaws were located near the boundaries of cut-off zone of repaired welds and likely had originated after near-boundary passes of repair welding [3]. [Pg.196]

The CamuS system consists of a number of components, both hardware and software, as shown in Figure 1. The hub of the system is the data acquisition unit, which collects and stores ultrasonic data in the form of RF waveforms. An accurate probe position monitor provides information on the location and orientation of the probe as it is scanned over the test object. Software tools have been developed to provide assistance to the user with preparing inspection procedures according to the requirements of prEN1714 with visualising the data, in relation to the test object with making measurements of any indications present and with classifying indications. [Pg.765]

In order that the data acquisition system can obtain information about the spatial location and orientation of the probe, a four-channel incremental encoder interface board is installed. Three channels are used to define position in three-dimensional space, while the fourth monitors the skew of the probe (skew is defined as rotation about an axis normal to the probe face). Although six measurements are required to completely define the location and orientation, it is assumed that the probe remains in contact with the inspection surface. [Pg.768]

Today the demand for inspection of components with complex geometry, difficult access conditions or location in a hazardous environment is steadily increasing. Documentation, reproducibility and minimised health risk for the inspection staff are key issues. This leads to an increased demand for automated inspection, resulting in a need for new, advanced scarmer systems for NDE. [Pg.799]

The virtual transducer can be placed in a specific location on the test object surface, it can be moved along a path (e.g. a robot scanning path generated off-line or a path resulting from a real inspection sequence) or it can be moved along the surface, dynamically updating the ultrasonic sound propagation in the material. [Pg.871]

Another fundamental characteristic ofNDT data is that it is spatial. It is the use of an NDT signal, together with its location, which provides insight into the hidden nature of the test-piece. Any discussion of NDT inspection data assumes the spatial component is included. [Pg.1015]

A large percentage of eddy-current inspections are conducted in the field, away from the home base and often in remote or inaccessible locations. Using local telephone lines or mobile phone lines would allow the inspector to beam his data back to the office. In this way highly qualified personnel can be consulted when problems or difficult to interpret results occur. Inspectors no longer need to feel isolated on site. [Pg.1020]

In order to maintain Class and to comply with international legislation a ship must undergo surveys at prescribed intervals. Ships such as tankers and bulk carriers must comply with International Maritime Organisation resolutions which require a Class Enhanced Survey Programme. This programme includes Special Surveys at five yearly intervals with close-up visual inspection and thickness measurements to be made at specified locations, the number of which increases with the age of the ship. [Pg.1045]

There are no classification requirements for routine NDE beyond thickness testing and visual inspection except for repairs, modifications or where service history has identified a specific problem in which case the Surveyors will request NDE at the same locations in similar ships. Under circumstances where visual inspection has found evidence of fatigue cracking the Surveyor can also call for NDE to assess the full extent... [Pg.1046]

One of the earliest NDT applications for laser-based profilometry systems was for the inspection of marine boiler tubes. Under funding from the U.S. Navy", several systems were developed that were capable of rapidly and accurately mapping the inside surface of 25 mm and 50 mm diameter boiler tubing. Features such as internal pitting and corrosion can be located and quantitatively assessed using computer-graphic analysis. The system employs an... [Pg.1063]

Other examples of government and military applications of laser-based profilometry include the evaluation of rocket thruster nozzles to locate and measure flame erosion remote inspection of hypervelocity test track and the measurement of sludge deposits on tube internal surfaces. [Pg.1066]

Finding the End Point Potentiometrically Another method for locating the end point of a redox titration is to use an appropriate electrode to monitor the change in electrochemical potential as titrant is added to a solution of analyte. The end point can then be found from a visual inspection of the titration curve. The simplest experimental design (Figure 9.38) consists of a Pt indicator electrode whose potential is governed by the analyte s or titrant s redox half-reaction, and a reference electrode that has a fixed potential. A further discussion of potentiometry is found in Chapter 11. [Pg.339]

Nondestmctive evaluation, also termed nondestmctive testing or nondestmctive inspection, is extensively used in weld testing (14). Nondestmctive tests do no impair the serviceabiUty of the material or component under stress. The most widely used tests for evaluation of welds are Hquid penetrant, magnetic particle, ultrasonics, and radiography. Acoustic-emission tests are increasingly used. Nondestmctive tests detect and characterize, in terms of size, shape, and location, the various types of weld discontinuities that can occur. [Pg.349]

Weld inspection duties of personnel responsible for judging the quahty of welding with regard to specifications have been treated (15). Some of these duties involve the visual inspection of welds to determine if they are of the proper size, location, and type and are free of defects. Specifications of materials used must be checked, as must equipment and procedures. [Pg.349]
