Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting is required.
This document replaces GB/T 35419-2017 "Storage of Ecode in one-dimensional barcode for Internet of Things Identification System" and is compatible with GB/T 35419-
Compared with.2017, in addition to structural adjustments and editorial changes, the main technical changes are as follows.
a) Changed the symbology requirements for Ecode stored in a one-dimensional barcode (see Chapter 5, Chapter 5 of the.2017 edition);
b) Increased the maximum symbol length that Ecode can store in a one-dimensional barcode (see Chapter 6);
c) Added human-readable character requirements (see Chapter 7).
