BS EN 26948:1991 自动凝汽阀生产和性能特点试验规范

This International Standard specifies tests applicable to automatic steam traps. These tests, which are hereafter referred to as production tests and performance characteristic tests, may be conducted to ensure the correct functioning of a steam trap or to evaluate the performance of a particular design. This International Standard specifies the tests to be performed relative to each one of these two categories and describes briefly the corresponding test methods.

BS EN 27842:1991 自动凝汽阀排放量的测定方法

This International Standard specifies two test methods to determine the discharge capacity of automatic steam traps to ISO 6552.

Methods for determination of discharge capacity of automatic steam traps

BS EN 27841:1991 自动凝汽阀蒸汽损失的测定方法

This International Standard specifies two test methods to determine the steam loss of automatic steam traps to ISO 6552. The object of these tests is to determine the amount of live steam, if any, that is lost through the steam trap. They are, therefore, tests to evaluate the ability of the traps to shut against steam during successive operations. There is no measurement of the total heat energy lost by the trap. Such total heat loss would include radiation and convec-tion components which can be established separately.
