Joint inspection

The pulser/receiver HILL-SCAN 30XX boards satisfy DIN 25450. Typical applications are ultrasonie imaging systems for nuclear power stations and for aircraft, material characterization, transducer qualification, replacement of portable flaw detectors (inspections of welded joints), inspection of new materials, measurement systems with air eoupling. ... 

A similar agreement to the MRAs is the Protocol to the European Agreement on Conformity Assessment and Acceptance of Industrial Products (PEC A) made public by the EC in March 2002. It was prepared in order to facilitate the operation of the annex on GMP for medicinal products inspections and batch certification to such PECAS. The type of information that should be exchanged between the EU and associated countries and the obligations with respect to joint inspections and inspector training are also delineated. 

The transition period began in December 1998. During the transition period, FDA and EU authorities were to participate in such confidencebuilding activities as the exchange of inspection reports and cooperate on joint inspections and training [23]. These activities would enable a party to assess equivalence of its counterpart regulatory authority. 

Self-Inspection Program (4) Employees/supervisors well trained and conduct routine joint inspections with all finding corrected. (3) Employees trained in inspection techniques, and all routinely participate in workplace inspections. (2) Routine inspections conducted by selected personnel with appropriale corrective actions taken. (1) An inspection program exists, but few employees involved and cova-age/ corrective actions spotty. (0) No routine inspection program in place at facility. 

The various authorities (e.g. Finnish Environment Institute, the regional OHS governmental authorities) could consider a joint risk assessment procedure. This would mean that every enterprise could assess all risks simultaneously, taking account of all sectors of its activity. In addition, joint inspections could be... 

There was some dissatisfaction among safety representatives about follow-up action after joint inspections. This echoes other research which found that... 

Unimpeded inspection PCAs that have gone throngh a proper aqneous cleaning process are easy to inspect because there is no flux residue on the surface to interfere with solder-joint inspection by eye or automated optical inspection devices. 

Difficulty of Inspection. No-clean residues, especially from surface-mount technology (SMT) soldering, are generally hard, transparent polymerized deposits that interfere to some degree with solder-joint inspection. The deposit can crack and sometimes operators will mistake the cracked flux residue deposit for solder-joint cracking. The residue is also reflective, which can interfere with visual inspection or automatic optical inspection (AOI) methods. 

X-ray solder joint inspection systems can reach average inspection speeds of around 50 to 150 joints per second. X-ray solder joint inspection systems also have higher prices, typically about 50 to 100 percent more than the price of the optical solder joint systems with the fastest inspection speed capability.

Representatives of the EPCM contractor and the construction contractor jointly inspect the works and review the corresponding documentation, any uncompleted works or documentation discovered being entered on a list of... 

Employees/supervisors are well trained and conduct routine joint inspections with all findings corrected. 

Hazard identification (inspection) Employees and supervisors are trained, conduct routine joint inspections, and all items are corrected.

Joint inspection difficult after assembly and NDT techniques currently inadequate. Quality control should include intermittent testing of Joint strength from samples taken from the production line.
