898. In a relational database (Access), the data in one table is related to the data in other tables. In general, tables can be related in one of three different ways: one-to-one, one-to-many or many-to-many. The relationship is used to cross reference information between tables.
Definition of BURSTING STRENGTH. : the capacity of a material (such as a paper or textile) or object (such as a metal pipe) to maintain in continuity when subjected to pressure; broadly: the pressure often expressed in pounds per square inch required to rupture such a material or object under rigidly controlled conditions.ADVERTISEMENT.efinition of BURSTING STRENGTH. : the capacity of a material (such as a paper or textile) or object (such as a metal pipe) to maintain in continuity when subjected to pressure; broadly: the pressure often expressed in pounds per square inch required to rupture such a material or object under rigidly controlled conditions.

Maximum operating and required minimum bursting pressures at 73oF (23oC) for PVC pipe fittings according ASTM D1785 Standard Specification for Poly Vinyl Chloride (PVC) Plastic Pipes Schedules 40 and 80 are indicated in the diagram and table below:ote! The maximum operating pressures derates with temperature. At the maximum operating temperature for PVC - 140oF (60oC) - the strength is derated to approximately 20% of the strength at 73oF (23oC) . Be aware that maximum operating pressures varies with the fittings design. Consult the manufacturing data.
