This standard establishes a vocabulary of terms, with their definitions, applied in the field of rolling bearings and their technology.
2 Principles and Rules Followed
2.1 Organization of the vocabulary
The vocabulary comprises:
a) terms, with their definition, in systematic order;
b) figures with index numbers of relevant terms;
c) alphabetical listings of the terms, with their index numbers.
2.2 Organization of terms and definitions
The terms and definitions are given in groups and subgroups, arranged in systematic order.
A two-digit serial number is as-signed to each group, beginning with 01 for Bearings.
Each group is divided into sub-groups, to each of which is as-signed a four-digit serial number, the first two digits being those of the group.
Each entry is assigned a six-digit index number, the first four digits being those of the subgroup.
2.2.1 Organization of an entry
Each entry contains an index number, the term and the text of the definition. An entry may also include a note and/or reference to one or more figures [for example (Figure 5.)]
The index number and the term are printed in bold type. In some entries the term is followed by a qualifier. A qualifier is printed in normal typeface in angle brackets, (), and indicates a directive for the use of the term or a particular field of application of the term as defined.
The absence of a generally accepted term for the concept in the language is indicated by a row of dots.
2.2.2 Use of parentheses
In some terms a word or words printed in bold typeface are placed between parentheses. These words are part of the complete term, but they may be omitted when use of the abridged term does not introduce ambiguity.
2.2.3 Use of [square] brackets
When several closely related terms can be defined by the same texts apart from a few words, the terms and their definitions are grouped in a single entry. The words to be substituted for those which precede them in order to obtain the different meanings are placed in brackets, i.e. [], in the same order in the term and in the definition.
