12、ISO 11639:2010 ISO 11639:2010(E) iv ISO 2010 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical co
13、mmittees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with th
14、e International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft Internati
15、onal Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be

Standardization on certain numbering systems pr
18、ovides for numbering simplicity, ease of interchangeability, and the suppression (as required), standardization and limitation of usable codes. 2 Terms and definitions For the purposes of this document the following terms and definitions apply. 2.1 basic standard number stem number number that is th

20、 sequential and contains no coding 2.4 digit number, alpha character or symbol that occupies a space within a part number 3 Construction of part numbers 3.1 Part number length To the maximum extent possible, part numbers should be limited in length to 15 digits. Part numbers up to 20 digits in lengt
21、h are acceptable, if required to fully differentiate part numbers. 3.2 Basic numbers It is recommended that the basic standard number be a maximum of seven digits in length. 3.3 Size codes Size codes for hose assemblies shall be in accordance with Table 1.

24、h = four digits in inches: first three digits in whole inches, last digit in 1/8 inch. Hose assembly lengths shall be coded in whole millimetres. The length code of a hose assembly shall always be three digits long, using zeros when necessary. For hose assemblies length W 1 m, the length code shall
25、be defined using a prefix letter.

Running letter or number codes consecutively should be avoided but is not prohibited. A hyphen shall c

When establishing a new basic series of numbering, issuance of the short basic standard number series sh

Typical fluid system parts requiring this would be hose assemblies and reducer/expander tee fittings. A short basic standard number may also be needed to st

Letters, “I”, “O”, “Q”, “X”, and “Z” shall not be used. Other letters shall be upper-case (capitalized). Numbers shall be Arabic numerals. Blank spac
37、es are not permitted. Symbols such as parentheses ( ), asterisk *, degree , plus + and minus shall not be used, except when referencing a government or industry document whose identification contains such a symbol. The total length of the part number, including the dash number(s), shall not exceed 1
38、5 digits, except under special circumstances, where the part number length may be a maximum of 20 digits. The dash number shall have the same characteristics as the basic standard number and may be composed of numbers, letters or any combination thereof. Part standard drawing revision letters (if an
39、y) shall not be included in the part number. 4 Complex numbers 4.1 General The following option codes, sleeving codes, numeric size codes, letter size codes, length codes, and angular orientation codes are established standards for use in the construction of significant part numbers. Use of these co
40、des is not mandatory if a non-significant numbering discipline is used. 4.2 Hose assembly option codes Option code letters to be used in the part number shall be in accordance with Table 6.
