Rules for railway product identification code
1 Scope
This Standard specifies the terms and definitions, preparing principle, structure
and management of railway product identification code, product item
identification code.
This Standard applies to codes required as product identification and relevant
information processing, exchange and share carrier in railway product
management.
NOTE. Railway product management includes production management, product access,
product quality supervision and tracking, material management, operation management, asset
management, material accounting, planning and statistics.
2 Normative references
The following standards contain the provisions which, through reference in this
Standard, constitute the provisions of this Standard. For dated references,
subsequent amendments (excluding corrections) or revisions do not apply to
this Standard. However, the parties who enter into agreement based on this
Standard are encouraged to investigate whether the latest versions of these
documents are applicable. For undated reference documents, the latest
versions apply to this Standard.
GB/T 10113, Definition of common terms used in classification and coding
3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T
10113 and the following ones apply.
3.1 product
the result of a set of interrelated or interacting activities that convert input into
output
NOTE. Common product categories include services (such as transport), software (such as
computer programs, databases), hardware (such as engine mechanical parts, electronic
components), process materials (such as lubricants). The product in this Standard specially
refers to hardware and process materials, of which.
1) the hardware is usually a tangible product, the amount of which is counted;
2) the process materials are usually tangible products, the amount of which has a
characteristic of continuity.
3.2 product item
a group irrelevant to manufacturer, divided according to the basic attribute
NOTE. The basic attribute refers to the specifications, geometry, size, material, performance
and production process characteristics for which the product can be distinguished from other
products.
3.3 product identification code
a set of numbers used to identify a particular product of manufacturer
3.4 product item identification code
a set of numbers used to identify a particular product item of manufacturer
3.5 railway product
an industrial product used on railway that meet the requirements for quality,
safety of this product
4 Rules for identification codes of railway product,
product item
4.1 Principle of uniqueness
4.1.1 The same product of same enterprise shall be assigned with same
product identification code. The different product of same enterprise or the
same product of different enterprise shall be assigned with different product
identification code.
4.1.2 The product of same name and same basic attribute shall be assigned
with same product item identification code. For the product of different name or
of same name, different basic attribute shall be assigned with different product
item identification code.
4.2 Principle of no meaning
In addition to the preset identification, each digit in the identification code does
not represent any specific information related to the product and the product
item.
Annex A
(normative)
Calculation method for verification code
A.1 The verification code is 1 number. The verification code is calculated by
a certain mathematical algorithm based on the numerical sequence. The
calculation steps are as follows.
step 1. prepare code weights from left to right, with a weight of 1 from the left
odd and 3 of an even number;
step 2. multiply by left-to-right numbers and weights, sum all multiplication
results;
step 3. after the sum of step 2 is divided by modulo 10, take the remainder;
step 4. If the remainder is 0, the verification code shall be 0; if the remainder is
not 0, the result of subtracting the remainder obtained in step 3 from
the modulo 10 shall be the verification code.
A.2 Example for calculation of verification code. see Table A.1 for calculation
of verification code of code 15254400005X.
Table A.1 -- Calculation for verification code of code 15254400005X
Step Example calculation explanation
1 Number from left to right
2 Multiply by left-to-right numbers and weights; sum all multiplication results 1+15+2+15+4+12+0+0+0+0+5=54 ○1
3 Divide ○1 by the modulus to take the remainder
54 (and) / 10 (modulus) = 5, the
remainder is 4 ②
If the remainder is 0, the verification code shall be
0; if the remainder is not 0, the result of
subtracting the remainder obtained in step 3 from
the modulo 10 shall be the verification code.
Verification code X = 10 (modulus) - 4
(remainder) = 6 ③
