Introduction

In order to standardize the quality evaluation of basic electromechanical relays for telecommunications in my country, guide the formulation of product standards for enterprises, and promote product development and production GB/T 16608 aims to establish general specifications and blank detailed specifications applicable to basic electromechanical relays for telecommunications, and to provide industrial and other equipment with relays for reference:

GB/T 16608 is proposed to be divided into the following parts:

--- Part 1: General specification and blank detail specification: The purpose is to establish suitable for telecommunications equipment, industrial equipment and other equipment relay General specification for electrical appliances and for use in detailed specifications developed in accordance with this document:

--- Part 2: sub-standard: The purpose is to establish sectional specifications applicable to basic electromechanical relays for specific applications:

Basic electromechanical relays for telecommunications with qualification Part 1: General specification and blank detail specification

1 Scope

This document applies to basic electromechanical relays for telecommunications: Relays conforming to this document are suitable for use in telecommunication equipment, but as a basic Basic electromechanical relays are also suitable for use in specific industrial and other equipment:

This document selects the appropriate test methods from IEC 61810 (all parts) and other documents for the detailed specification developed in accordance with this document use: Basic inspection tables are also specified in this document, applicable to detail specifications developed in accordance with this document:

Detailed inspection tables are specified in the detail specification:
