Inspections purpose

Do fix labels to all devices that have been designed for inspection purposes and indicate their calibration status. 

Lead. For pipe thread inspection purposes, lead is defined as the distance from a point on a thread to a corresponding point on the adjacent thread measured parallel to the thread axis (Figure 4-373). 

Apart from bottom blowdown valves (main BD valve), other types of valves are often employed. Blowdown valves also can be used to control high water levels, drain the boiler for cleaning or inspection purposes, and maintain chemical concentrations and water chemistry below maximum permitted levels. 

In Anglo-Saxon countries a test in a ballistic mortar is also used. Tests for explosive power should be repeated occasionally for inspection purposes in production. 

Special permitted explosives are tested under much more drastic conditions. As previously stated 1 kg of inversely-initiated explosive is fired creating a cloud of coal-dust. The number of test shots should not be less than 20. Safety in the. presence of coal-dust is also tested by a special method worked out by Cybulski, which consists in firing two charges, each weighing 1 kg, simultaneously from two opposite mortars. The distance between the mortars is 1 m. A cloud of coal-dust is obtained as described above. The charges are inversely initiated. The number of shots is 20. The test is considered exceptionally stringent. Such tests are repeated from time to time for inspection purposes. 

Quantitative tests are rarely conducted in magazines and for production inspection purposes except for a test devised by Bergmann and Junk [62] in which the quantity of acid products (calculated as NO) evolved by the powder is determined by titration. The quantity of NO evolved on heating for 2 hr at a temperature of 132°C should not exceed 2.5 cm3 NO per 1 g of powder. (For more details see Vol. II p. 26.) Other quantitative tests are usually employed in research. 

Mexican motor carriers may meet the requirements by obtaining insurance coverage, in the required amounts, for periods of 24 hours or longer, from insurers that meet the requirements of 387.35. Mexican motor carriers operating under temporary insurance must keep the following docrunents in their vehicles for inspection purposes ... 

Technical file. The manufacturer s technical documentation file supports the CE marking. The contents of a technical file generally include the declaration of conformity, name and address of manufacturer, product description and identification, list of standards and directives applied, design and schematic drawings, calculations, test reports, parts lists, manuals, and so on. Technical files must be readily available and may be requested by enforcement authorities for inspection purposes should a product become suspect or an incident occur. 

El-evation of the reactors to facilitate refuelling frcm the underside althou having tenperature benefits for charge route ccsrponents has resulted in the only access to the reactor.outlet plenium for inspection purposes being by way of 7" diameter control rod stanc ipes. 

Use only standard low-voltage handlamps for inspection purposes. The plug on the end of the flexible cable must only be inserted in the correct low-voltage sockets. 

For occasional jobs of limited duration, where an operator may need to carry out minor touch-up work or needs to enter a spray area for quality control inspection purposes, etc., it is accepted that a full canister respirator complying with BS 2091 (1969) and fitted with a type CC canister may be worn provided that the facepiece is a correct fit and that the canister is changed after successive brief periods totalling 15 min spraying, or otherwise in accordance with the makers instructions. The use of a canister respirator is, however, considered to be very much a second choice in comparison with the superior protection afforded by a continuous flow airline breathing apparatus. Firm controls must be exercised to ensure that the conditions attached to the use of canister respirators are fully observed. 

Extensive trials using this equipment have been carried out in AEA Technology s test facilities to assess the reliability, safety features and to optimise waste recovery and handling piocedures This grab has also been deployed in the leactor to recover waste Items foi inspection purposes (Figure 3)... 

To the extent that it meets inspection requirements, information from routine facility operations, with appropriate data authentication, shall be used for inspection purposes. 

The agreed list of the documentation and records to be routinely made available for inspection purposes to the inspection team by the inspected State Party during an inspection, as well as arrangements with regard to access to such records for the purpose of protecting confidential information, are contained in Attachment 8. Such documentation and records will be provided to the inspection team upon request. 

DATUM reference a defined point, line, or plane used to locate the pattern or layer of a printed board for manufacturing and/or inspection purposes. 

The removable floor at El 620.0 shall have a man-hatch to provide access to the tendon gallery for inspection purposes. If it becomes necessary to take large tools or parts into the tendon gallery, the steel floor at El 620.0 may be lifted out to grade. 

In the lower area of the vessel a manhole with the nominal width of DN800 is provided for cleaning and inspection purposes. On the elliptical vessel top, a head access hole with the nominal width of DN300 is provided. The head access hde will be opened to control if the vessel is really empty before the inspection is carried out Unfortunately there have already been accidents when a manhole was opened because a defective level control signalled an empty vessel although it was still full. Furthermore, the head access hole enables the analogous level control to be cahbrated (see section 4.10, Commissioning ). 

Pulsed irltrasoimd is rrsed for inspection purposes including medical imaging, sonar, acoustic microscopy, and nondestmcdve evalrrahon. In a pulsed system a transducer is placed in contact with a sample, electrical driving signals are sent to the transdncerto make pulses of irltrasonic waves, which enter the sample and echoes from internal scatterers are collected by a receiver, processed, and displayed for interpretation (see Fig. 8). 

Another, but deconstructive method is the control of the bond by dismantling the part and by visible inspection of the bond. This parts audit can be done regularly like once a day, a week, or months depending on the importance of the application. Car bodies or parts of a body, which are using adhesive bonding in addition to older methods like spot welding, are regularly put apart for inspection purposes.
