Revision of the Requirements for Manufacturing and Production Tests (UL 80 - PR4484) STP BALLOTS DUE: February 12, 2007 COMMENTS DUE: February 12, 2007 IMPORTANT: Please note that because individual proposals may contain interdependent references or content, m
4、any individual proposals have been combined into one proposal item, Topic 1 below, in order to facilitate the process. Because the individual proposals merged into Topic 1 have been received from multiple sources, those sources and their associated rationales have been identifi ed and delineated bel
5、ow under the headingRATIONALE. Finally, due to their interdependent nature, the merged set of multiple proposals in Topic 1 are being balloted in combination as one ballot item under Topic 1. Note that Topic 2 is an additional ballot item. For your convenience in review, proposed additions to existi
6、ng requirements are shown underlined and proposed deletions are shown lined-out. 1.

10、on or networking permitted without license from IHS -,-,- FOR INTERNAL UL OR CSDS USE ONLY NOT FOR OUTSIDE DISTRIBUTION Rationale:The proposed revisions for the addition of Section 5B are intended to clarify the UL 80 Tank Accessories that may optionally be provided with the tank, identifi cation of
11、 the specifi c requirements these components must comply with, and minimum sizes to match the intended use of the tank. The proposed revisions are intended to add Physical Abuse Tests to UL 80 prior to conducting the hydrostatic pressure test to ensure the tank design type and accessories can meet e
12、xpected normal and abnormal conditions of transport, assembly, installation and use. Also documented in this general section are selection of samples, identifi cation of tests, assembly of accessories, tank placement and test fl uids. The hydrostatic test details were deleted (if too restrictive) or
13、 moved to another section. 15B Handle Strength This proposed test is intended to evaluate handles or lugs provided with the tank at a 2X safety factor. This test simulates normal tank transportation and is similar to requirements of other oil tank standards (UL 142, ULC S603 a) Upon installation pit
