Standard Guide for Videoborescoping of Tubular Products for Sanitary Applications
SIGNIFICANCE AND USE
5.1 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.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
