Understanding the 10/13 Rule in Design by omeshchem is a document available to read on EtoBox.

The document discusses the "two-third (2/3) rule" and "ten-thirteen (10/13) rule" for determining if a pressure relief device is required for tube rupture. Both rules are derived from the criteria that the design pressure of the low pressure side must be a certain ratio of the high pressure side design pressure for tube rupture to not be considered a relieving scenario. The two-third rule follows older standards where test pressure was 150% of design pressure, while the ten-thirteen rule follows newer stand
