GB/T 14960-2017Technical requirements and measurement methods of infrared remote control radiation unit for television broadcast receivers (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 14960-1994 "Technical requirements and measurement methods for infrared remote control transmitters for television broadcast receivers", and GB/T 14960-1994 compared to the main technical changes are as follows:

--- canceled the "naming method" "surface hardness" (1994 edition 5.3,6.1) requirements;

--- Increased requirements and test methods for "carrier frequency" (see 4.14)

--- Adjust the scope of the "key load force" (see 4.16,.1994 edition 8.2); - a more detailed description of the "drop test" (see 4.22.6,.1994 edition 9.6); - A more detailed description of the "Solvent Resistance Test Method" (see 5.2.7,.1994, version 6.4.2). This standard is proposed by the Ministry of Industry and Information Technology (electronic) of the People's Republic of China. This standard is nationalized by the National Audio, Video and Multimedia Systems and Equipment Standardization Technical Committee (SAC/TC242). The standard drafting unit.

1 Scope

GB/T 14960-2017 is the Chinese national standard on technical requirements and measurement methods of infrared remote control radiation unit for television broadcast receivers, in the field of telecommunications and audio-video engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 31 May 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 December 2017. Classification: ICS 33.100.10, CCS M74. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the TV broadcast receiver (hereinafter referred to as TV) supporting infrared remote control transmitter technical requirements and test methods. This standard applies to the TV with infrared remote control transmitter (hereinafter referred to as the remote control), with infrared remote control function of similar products Supporting the use of infrared remote control transmitter can also refer to the use.
