This Outline of Investigation contains basic requirements for products covered by UnderwritersLaboratories Inc. (UL) under its Follow-Up Servic
3、e for this category within the limitations given below andin the Scope section of this Outline of Investigation. They are subject to revision as further experience andinvestigation may show is necessary or desirable.B. The observance of these requirements by a manufacturer is one of the conditions o
4、f the continuedcoverage of the manufacturers product.C. A product which complies with the text of this Outline of Investigation will not necessarily be judged tocomply with the Outline of Investigation if, when examined and tested, it is found to have other featureswhich impair the level of safety c
5、ontemplated by these requirements.D. A product employing materials or having forms of construction which conflict with specific requirementsof the Outline of Investigation cannot be judged to comply with the Outline of Investigation. A productemploying materials or having forms of construction not a
6、ddressed by this Outline of Investigation may beexamined and tested according to the intent of the requirements and, if found to meet the intent of thisOutline of Investigation, may be judged to comply with the Outline of Investigation.E. UL, in performing its functions in accordance with its object
7、ives, does not assume or undertake todischarge any responsibility of the manufacturer or any other party. The opinions and findings of ULrepresent its professional judgement given with due consideration to the necessary limitations of practicaloperation and state of the art at the time the Outline o

UL shall notincur any obligation or liability for damages, including consequential damages, arising out of or inconnection with the use, interpretation of, or r
9、eliance upon this Outline of Investigation.F. Many tests required by the Outline of Investigations of UL are inherently hazardous and adequatesafeguards for personnel and property shall be employed in conducting such tests.AUGUST 6, 2003SUBJECT 676A4INTRODUCTION1 Scope1.1 This outline covers compoun
10、ds intended to be used to encapsulate grounding and bonding conductorsplices or terminations in swimming pool, spa, or fountain equipment such as fixtures, fixture housings,and junction boxes where the splices or terminations may be exposed to salt-free swimming pool orfountain water and sunlight fo
11、r varying lengths of time, including continuous exposure. This outline alsocovers potting compounds used to fill underwater junction boxes.2 General2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory orapproximate information.3 Glossary3.1 DIMENSIONAL STA
12、BILITY SAMPLES Test samples prepared in accordance with 5.1(c) andused to condition the potting compound and assess its dimensional stability.3.2 FIELD CONFIGURATION SAMPLES Test samples prepared in accordance with 5.1(a) intendedto represent the mounting of a brass terminal on a wall of a swimming
13、pool or fountain equipment, thetermination of a grounding or bonding conductor, and the encapsulating of the termination and terminalwith the potting compound.3.3 LAP-SHEAR SAMPLES Test samples prepared in accordance with 5.1(b) and used to facilitateconditioning of the potting compound and assess t
14、he adhering properties of the potting compound toone or more substrate material types.3.4 SUBSTRATE MATERIAL TYPE The type of material to which the potting compound is confirmedto adequately adhere.MARKINGS4 General4.1 The smallest unit container in which the compounds are packaged shall be marked w
15、ith the followinginformation:a) The manufacturers name and compound material designation.b) This compound is for use where exposed only to fresh swimming pool or fountain water andsunlight or the equivalent.c) For use only where adhering to copper alloy, stainless steel, and (other materials asappli
16、cable) or the equivalent marked on the container. The marking shall include only thosematerials to which it has been determined to adhere.AUGUST 6, 2003 SUBJECT 676A 54.2 Other markings or literature included with the compound shall not describe its use where exposed todeteriorating conditions or wh
17、ere adhering to materials other than those determined to be appropriate asdescribed in 4.1.4.3 The container for a compound determined to provide insulation resistance through the testprocedures involving only the lower voltages described in the Exceptions to 7.4 7.6 shall be markedEncapsulate only
18、grounding and bonding conductor splices. Literature included with the compound shallfurther indicate that the compound is not suitable for filling swimming pool junction boxes, underwaterjunction boxes, or other enclosures in which the splices or terminations of other than grounding andbonding condu
19、ctors are contained.SAMPLES5 General5.1 The following samples are required to complete the testing. These samples are to be subjected to theExposure Conditions, Section 8.a) Field Configuration Samples Samples of nominal 8 cm (3 inch) square panels of thesubstrate material type identified in the mar
20、king of 4.1(c) and having a nominal thickness in therange of 0.5 1.5 mm (0.020 0.060 inch). In or on each of these panels, two brassgrounding/bonding terminals typically used in swimming pool and fountain equipment shall beinstalled as intended separated by 13 25 mm (1/2 1 inch). The grounding/bondi
21、ng terminalsare to be fitted with a test conductor that is a 30-cm (12-inch) length of No. 8 AWG (8.4 mm2),Type RHW, solid copper wire. The potting compound is then to be applied to the terminal sideof the samples in accordance with the instructions included with the potting compound. Thepotting com
22、pound is to also be applied to the opposite side of the samples and to all otherexposed metal in the same thickness specified in the instructions to facilitate sample immersionwithout the wetting of the metal parts on the panel.b) Lap-Shear Samples Each sample is to be prepared with two panels of th
23、e substratematerial type, each 2.5 by 10 cm (1 by 4 inches) and having a thickness as specified in Table5.1. Stainless steel shall be an American Iron and Steel Institute (AISI) alloy type 304 or 316,also known as alloy S30400 and S31600, respectively, in the United Numbering System (UNS).The two pa
24、nels are to be adhered together with a 25-mm (1-inch) overlap using the pottingcompound with it applied in 3.2 mm (1/8 inch) thickness. The long access of each panel is toalign with the long access of the adjoining panel. For more specific sample features, see therequirements for Bond Strength of Pl
