ISA 93.00.01

W/D NO S/S

This Standard applies to the classification of valve design andprovides the methods for the testing of valve stem(s) and bodyseal(s). This Standard is not intended for production testing andexcludes control valves.

The results of the test methods shall classify valve designs toperformance levels per the following selections:

a) Test temperature

b) Pressure rating

c) Leakage (concentration, parts per million)

d) Mechanical cycles (number of)

e) Thermal cycles (number of)

f) Adjustment(s) to seal(s) and/or number of adjustments

Test methods per this Standard shall apply only to valves withthe following stem motion designs:

a) Rotating and rising

b) Rotating and non-rising

c) Non-rotating and rising

The classification shall apply only to the stem(s) motion designof 1.2, which is tested.

The test results of a particular valve may be used to extend theclassification to other valves per the following guidelines:

a) To valves with identical stem(s) and body seal(s) material,geometry, and loading characteristics, when the stem(s) and bodyseal(s) diameters are within ±25% of the tested diameters

b) To valves otherwise identical, meeting the criteria of 1.4a,which are applied below the tested temperature, down to ambienttemperature

c) To valves otherwise identical, meeting the criteria of 1.4.a,which are of a lower pressure rating

Valves intended for vacuum service are beyond the scope of thisStandard.

Purpose

The purpose of this Standard is to establish a uniform processfor assuring that manual and automated on-off valves are testedusing uniform methods and will meet user needs in complying withvolatile organic compounds (VOC) fugitive emissions requirements.The test method is not intended to be a pass-fail criteria.
