4.27.1 Language. Unless otherwise specified, drawings and associated lists shall be in the English language. Language Style. Notes shall be concise statements using the simplest words and phrases for conveying the intended meaning.
4.27.2 CommonLy Used Words and Phrases. Certain words and phrases are frequently used on a drawing. The following rules shall be applied:
(a) Reference documents shall be cited using “per,”“conforming to,”“as specified in,” and “in accordance with” or “lAW.”
(I,) The phrase “Unless Otherwise Specified” or “UOS” shall be used to indicate a default requirement. The phrase is used at the beginning of the note or denoted at the head of the “NOTES” column. This phrase shall be used when the default is a generally applied requirement and the exception can be clarified by providing a reference to another document or requirement on the drawing.
4.27.3 Use of Shall, Will, Should, and May
(a) “Shall” establishes a mandatory requirement.
(b) “Will” establishes a declaration of purpose on the part of the design activity.
(c) “Should” establishes a recommended practice.

4.27.4 Indefinite Term. The indefinite term “and/or” shall not be used.
4.2 7.5 Location of Notes. Notes shall be located on sheet 1, or a reference shall be included on sheet I indicating note location. When notes are included on a separate parts list, expand the note required by ASME Y14.34 to read similar to the following: “SEE SEPARATE PARTS LIST FOR PARTS AND NOTES.” When notes are continued beyond a given drawing sheet, information to that effect shall be inserted in the next note position of the applicable sheet, e.g., “NOTES CONTINUED ON SHEET 4.” Associated Lists and Drawings in Book Form. For associated lists and drawings in book form, the notes or textual data may be prepared and grouped on continuation sheet(s) of the drawing.
4.27.6 Drawing Notes — Contents. Drawing notes are pertinent data given in word form and used to complement the delineation of other given data. Drawing notes shall be concise, grammatically correct statements. The arrangement of the notes shall not be interpreted as an order of precedence, or sequence in manufacturing or assembly, unless specified as such on the drawing. The following shall be applicable in the preparation or use of notes:
(a) General notes apply to the entire drawing or associated list.
(b) Local notes are located at the specific area or point of application. Local notes are not included in the listing of general and flag notes. Requirements specified by local notes apply only to the areas or points indicated.
(c) Flag notes are located with the general notes but apply only at specific areas or points on the drawing. A flag note shall be identified with a flag note symbol in accordance with (f). The flag note symbol, including the note number, shall be shown at each point of application. The flag note symbol is placed around the note number in the notes area to indicate that it applies at specific areas on the drawing. The flag note symbol, however, need not be shown in the “NOTE” column of the PL or in the “NOTE” column in a table.
(d) General notes and flag notes shall be numbered consecutively as a single listing starting with Note 1. Filling in voids, open spaces, to accommodate deletions is not required. Note numbers of deleted notes shall not be reused. Notes lists authored in a product data management system where notes are identified as database objects with unique identification and are subject to reuse may be numbered or identified nonsequentially.
(e) Reference to standardization documents shall be by basic identifier, excluding revision level, except where identification of a specific issue is essential to drawing interpretation.
