Coal Industry Standard of the People's Republic of China
Method for compiling models of safety helmet lamps for mining
Subject content and scope of application
MT/T 154.6--1995
This standard specifies the principles for compiling models of safety helmet lamps for mining (hereinafter referred to as mining lamps), the composition of models, the arrangement method, the compilation method and the model management and declaration method.
This standard applies to the compilation and management of mining lamp models. 2 Reference standards
MT/T154.1 Guidelines and management methods for compiling models of electromechanical products for coal mines 3 Compilation principles
3.1 The naming of mining lamp models should be concise. 3.2 Mining lamp models are composed of uppercase Chinese phonetic letters and Arabic numerals. 4 Composition and arrangement of product models
4.1 Mining lamp models are mainly composed of "product type code", "first characteristic code" and "main parameter code". If it is still difficult to distinguish after such indication, then add "Second Characteristic Code", "First Supplementary Characteristic Code", "Second Supplementary Characteristic Code" and "Modification Serial Number" one by one. 4.2 The composition and arrangement of the mining lamp model are as follows: 口www.bzxz.net

Product Type Code
5.1 The "Product Type Code" in the mining lamp model indicates the category of the product, which is indicated by the Chinese Pinyin letter "K". 5.2 The "First Characteristic Code" in the mining lamp model indicates the battery type, which is indicated by the Chinese Pinyin letter, see Table 1. Approved by the Ministry of Coal Industry of the People's Republic of China on August 25, 1995 and implemented on November 1, 1995

5.3 The "second characteristic code" in the model of a mining lamp is used for identification when the "product type", "first characteristic code" and "main parameter code" are the same, and the product has other functions in addition to lighting that need to be distinguished. It is expressed in Chinese pinyin letters, see Table 2. Table 2

The "main parameter code" in the miner's lamp model indicates the rated capacity (Ah) of the miner's lamp battery, expressed in Arabic numerals. 5.4
5.5 The "first supplementary characteristic code" and "second supplementary characteristic code" in the miner's lamp model are used for identification when the "product type", "first characteristic code", "second characteristic code" and "main parameter code" are the same, but it is necessary to further distinguish their related characteristics, and are expressed in Chinese pinyin letters. The "first supplementary characteristic code" indicates the lamp head structure type, and the "second supplementary characteristic code" indicates the battery characteristics. See Table 3 and Table 4. Table 3

Note: Maintenance-free means that under the specified operating conditions, no maintenance is required during use; low maintenance means that the battery has a water replenishment cycle of more than 2 months and a structure with a clearly visible liquid level.
5.6 Example of compiling mining lamp models:
Example 1: KSZ11SH(A) low-maintenance double-filament biogas alarm mining lamp 502
Example 2: KS8 lead-acid battery

6 Miner's lamp model declaration method
6.1 Follow MT/T154.1.
a. The following information should be provided when declaring: miner's lamp product manual, product technical conditions, general drawing and sub-general drawing, one copy each b. The application of product model should be submitted to the miner's lamp management unit authorized by the Electrical Equipment Sub-Technical Committee of the Coal Mine Special Equipment Standardization Technical Committee of the Ministry of Coal Industry from the beginning of design. After the product is identified, the confirmation procedure must be handled (if it is a derivative product that is no longer identified, the confirmation registration should be handled). It will take effect after formal confirmation. 6.2 For existing models of mining lamps, when the production is transferred to another factory, the original model can be used without re-application. If a major improvement is made during production and its main parameters or structure have been significantly changed, the product model should be re-applied for, and only the main parameters of the modified serial number shall not be changed. 6.3 When applying for the confirmation procedure of the product model, it is necessary to fill out the confirmation application registration form in triplicate, and attach a copy of the product identification certificate, a copy of the product enterprise standard and a color photo of the product. 503
