§50. Capitalization with Abbreviations: In an abbreviation, whenever letters are capitalized in ink print, a single letter must be preceded by the single capitalization indicator, and a sequence of more than one letter must be preceded by the double capitalization indicator.

i. The period applies to the abbreviation but does not end a sentence.

EST

§51. English-Letter Indicator with Abbreviations:

a. When a period follows an abbreviation, there are four possibilities to consider:

ii. The period ends a sentence but does not apply to the abbreviation.

iii. The period both applies to the abbreviation and ends a sentence.

iv. It is doubtful whether the period applies to the abbreviation.

In the case of ii, the English-letter indicator must be used or must not be used as if the period were not present. In case iv, the period should be considered as applying to the abbreviation and the appropriate rule must then be applied.

The use or non-use of the English-letter indicator with abbreviations does not depend upon the braille symbols with which the abbreviation may happen to be in contact, such as grouping symbols, braille indicators, fraction lines, the hyphen, or the slash.

b. The English-letter indicator must be used before an abbreviation which consists of one letter or of a combination of letters corresponding to a short-form word provided the abbreviation is not followed by a period which applies to it.

(no periods apply to these abbreviations)

c. The English-letter indicator must not be used before an abbreviation which consists of one letter or of a combination of letters corresponding to a short-form word provided the abbreviation is followed by a period which applies to it. The English-letter indicator must also not be used before an abbreviation whose letters do not correspond to a short-form word. In this case, whether a period applies to the abbreviation or not has no effect on the rule for the non-use of the English-letter indicator.
