Standard Guide for Videoborescoping of Tubular Products for Sanitary Applications

SIGNIFICANCE AND USE
This specification establishes some the key factors which govern the interpretation of videoborescoping tubular products for a specific application. It is recognized that the requirements for one application may be very different than those of another. Therefore, the specification allows for the inspection to be customized for the application by the user by allowing the purchaser to specify parameters which may be important for the application.
SCOPE
1.1 This standard covers guidelines for ordering and examining tubular products for sanitary applications by videoborescoping. This method uses movable camera probe at the end of a cable to examine the interior of a tubular product. The image is then transmitted to an external monitor for analysis. The method is normally used when inside surface imperfections, not normally detected by other nondestructive methods, may result in contamination of the product which is contained by the tubular product.
