There are 10 leakage rates specified in iso 5208 P = test pressu re, in A, aa, a, b, c, cc, d, e, ee, f, g and the rate a is the highest grades

Iso 5208 maximum allowable closure test leakage rate Cl= duct leakage class, cfm/100 ft2 at 1 in Note 2 the leakage rates only apply when discharging test fluid to the atmosphere.

The following table is for the allowable closure leak value testing with water at 1.1 times rated pressure and gas at low pressure (about 80 psig) or high pressure if specified by customer

For check valve allowable leakage rate, please see api 598 check valve allowable leakage rate. Valve leakage class is a standardized rating that defines the maximum allowable internal leakage through a valve when it’s fully closed These ratings range from class i (least strict) to class vi (most stringent). Understanding what is the maximum leakage rates acceptable can save homeowners significant amounts of money and prevent costly property damage

This guide will provide information about how to assess leaks and identify potentially problematic situations. The allowable leakage for test sections with different diameters is the sum of the computed leakage for each pipe size Minimum test time shall be two hours The maximum allowable leakage for the water main will be calculated using the following formula:

The most commonly used by gemco valve are class i, class iv and class vl

Class i is also know as dust tight and can refer to metal or resilient seated valves Class iv is also known as metal to metal The maximum permitted leakage is based on a cl (duct leakage class) of 6 for rectangular duct and 3 for round ducts, as defined by the equation
