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 of Standardization Documents"
drafted.
This document replaces GB/T 14482-1993 "Mechanical Counter", compared with GB/T 14482-1993, except for structural adjustment and editorial
In addition to the changes, the main technical changes are as follows.
a) In Chapter 1, "The corresponding mechanical transmission and display part of the energized mechanical timer can be used for reference";
b) Modified the definitions of the three terms "length counter", "transmission ratio" and "life", and added two terms "press counter" and "key" and
definition;
c) The title of Chapter 4 has been added with "Model and Nomenclature, Structure Dimensions", 4.1 Product Classification has been added, Table 3 has been revised, and "two" has been added.
Two main parameters, "bit" and "nine bits", modified the description of the model example, and deleted the content related to quality management that should not be included in the standard;
d) Combine the original standard color, shell, signage, appearance quality, etc. into 5.1 appearance;
e) Revised some performance parameters in Table 4;
f) The description of counting life has been revised, and the original standard table 4 is replaced by a×10n-1 (2≤n≤9);
g) Added 6.1 "Atmospheric conditions of the test";
h) The test steps of the life test are simplified, and the relevant content of sampling is placed in Chapter 7;
i) The test methods for "low temperature", "high temperature" and "constant damp heat" are given respectively, and the upper limit of the temperature test is increased from 50°C to 60°C.
The duration of the test was increased from 16h to 24h, and the duration of the constant damp heat test was increased from 10h to 24h;
j) Delete the visual inspection table in Table 7 and replace it with 6.2, 6.3, 6.4, 6.5, 6.6;
k) Added "7.1 Inspection Classification" and "7.2 Group Batching Principles";
l) The inspection item table is added, and the ex-factory inspection items are divided into "one-by-one inspection" and "sampling inspection", and 50 pieces are used as batch points.
boundary point;
m) The inspection time for type inspection is increased, and the inspection cycle is determined to be inspected every three years;
n) Modify the relevant content of the packaging to. packaging according to the requirements of GB/T 13384-2008, and add random documents for packaging
content;
o) The storage conditions of the counter are modified, and no specific requirements for temperature and humidity are made.
