36、mmittee (3TS PTS TC): Horizon Signal Technologies, Inc. (Chair) Ver-Mac, Inc. www.ver- OMJC Signal, Inc. John Thomas, Inc. Previous 3TS PTS TC participants include: North America Traffic, Inc. Tower Sign medium shading is a higher-level requirement; and no shading (no gray) signifies subordinate

37、 (or lower-level) requirements. 3.2.1.3 Conformance Column The notations and symbols in Table 1 are used to indicate status. NEMA TS 5-2017 Page 13 2017 National Electrical Manufacturers Association Table 1 Conformance Symbols Symbol Status M Mandatory M.# Support of every item of the group labeled

38、by the same numeral # required, but only one is active at a time O Optional O.# (range) Part of an option group. Support of the number of items indicated by the (range) is required from all options labeled with the same numeral # C Conditional N/A Not applicable (i.e., logically impossible in the NE

39、MA TS 5 scope) X Excluded or prohibited The O.# (range) notation is used to show a set of selectable options (e.g., O.2 (1*) would indicate that one or more of the option group 2 options is required to be implemented). Two-character combinations are used for dynamic requirements. In this case, the f

40、irst character refers to the static (implementation) status, and the second refers to the dynamic (use); thus, “MO” means “mandatory to be implemented, optional to be used.” 3.2.1.4 Support Column Symbols The Support column can be used in a procurement specification to identify the required features

41、 for the given procurement or by an implementer to identify which features have been implemented. In either case, the user circles the appropriate answer (Yes, No, or N/A) in the Support column. See Table 2. Note: In Table 2, for those entries that are mandatory, only Yes appears in the Support colu

42、mn. For those items that are optional, Yes/No/N/A appears in the Support column. Table 2 Support Column Options Entry Identifier Yes Supported by the implementation No Not supported by the implementation N/A Not applicable 3.2.1.5 Additional Project Requirements Column The Additional Project Require

43、ments column may be used in a procurement specification to provide additional notes and requirements for the device to be procured or may be used by an implementer to provide any additional details about the implementation. In some cases, default text already exists in this field, which the user sho

44、uld complete to fully specify the equipment. However, additional text can be added to this field as needed to fully specify a feature. 3.2.1.6 Instructions for Completing the RL In the Additional Project Requirements column, each response shall be selected from the indicated set of responses (for ex

45、ample: Yes/No/N/A), or it shall reference additional items that are to be attached. NEMA TS 5-2017 Page 14 2017 National Electrical Manufacturers Association If a conditional requirement is inapplicable, use the not applicable (N/A) choice. If a mandatory requirement is not satisfied, exception info

46、rmation shall be supplied by entering a reference Xi, where i is a unique identifier, to an accompanying rationale for the non-conformance. When the status is expressed as a two-character combination, the response shall address each element of the requirement; e.g., for the requirement “MO,” the pos

47、sible compliant responses are “yy” or “yn.” To claim conformance with NEMA TS 5-2017, an implementation shall satisfy the mandatory and selected optional requirements as identified in the RL.
