5.6.1.3.1.4 EAN-8 / UPC-E code - Additional test criteria
The EAN-8 code is a short version of the EAN-13 / UPC-A code, with 8 characters in place of 13 or
12 respectively. If a decoder can be set in this way, such a code can be extended with the
corresponding number of zeros, in order to obtain a 13-digit EAN-13 code from the EAN 8 code.
The EAN-8 code is intended in particular for use on small products.
The contents of the characteristics are also identical to those for the
EAN-13 codes (see also chapter 5.6.1.3.1.2), as is the identification
of the GS1 prefixes and the selection of the module size.
However, with the EAN-8 codes is not possible to attach code add-
ons, as with EAN-13 and UPC-A codes.
Furthermore, the EAN-8 instore code always represents a fixed
article number only.
A variable attachment for price or weight information is not specified.
For such requirements, it is necessary to utilise the EAN-13 code or
UPC-A code.
The UPC- E code is the reduced version of the UPC-A code.
In UPC-E symbology, the extension from 6 characters to 12 characters is already integrated in the
decoding algorithm. A conventional bar code scanner is always capable of displaying and
evaluating the extended 12-character code format of a normal 12-digit UPC-A code, if a 6-digit
UPC-E code is read.
Here, it is possible to select expansion to 12 digits.
The meaning of the characteristics is identical to that with the EAN-13 code, likewise the module
size selection.
5.6.1.3.1.5 Code 128 / GS1-128 - Additional test criteria
The GS1-128 code (formerly EAN 128) is a special form of code 128,
whereby a special data structure is applied. This has been specified by
the organisation GS1 Global. The REA ScanCheck 3n can also check
these special data structures and some additional characteristics of
this code type.
Activation of the
structure test
with the code 128 enables expansion
of the code test to data structures specified in accordance with HIBC
or ANSI MH10.8.2. Testing the data structure is switched off in the
factory settings. With the
<No>
setting, the structure test is switched
off.
In accordance with the GS1 specifications it is possible to limit the permissible module size
according to the respective application areas.
The standard setting is the table “SST #2” with a permitted module width of 0.495 mm to 1.016 mm.
With GS1-128, the
GS1 structure test
is activated as standard. If this code type is to be listed in
the test report as EAN-
128 (earlier designation), it is possible to select “
report as EAN128
”.
