6 Body
6.1 Subject content and scope of application
In the enterprise standard for products with model numbers, this chapter can generally explain the following three points: Explain the content specified in the enterprise standard for this product. Typical terms such as: a.
This enterprise standard for this product specifies the basic parameters, technical requirements, test methods, inspection rules and marking, packaging and other requirements of a certain product (i.e. the full name of the product with model number).
b. Explain the scope of application of the enterprise standard for this product. Typical terms such as: This enterprise standard for this product is applicable to a certain product (i.e. the full name of the product with model number) for a certain purpose. c. Explain the scope of non-application of the enterprise standard for this product. Since the enterprise standard for products with model numbers only applies to the product of this model, the scope of non-application can generally be omitted. If further clarification is required, the typical terminology can be used: This enterprise standard for this product is not applicable to similar products of other models.
The content of this chapter is not divided into articles, but should be written in paragraphs. 6.2 Reference standards
Refers to the standards directly mentioned in the enterprise standard for this product. The standard code and number and the full name of the standard should be listed. The referenced standards should be national standards and industry standards.
Standards that are not directly mentioned in the product enterprise standard but are indirectly used cannot be listed as referenced standards. For example, in the enterprise standard of a certain model of electric angle grinder, in order to highlight that its safety complies with national standards, it can be written in the relevant clauses that "the safety of the grinder complies with GB3883.3 "Safety of hand-held electric tools-Part 2 Special requirements for electric grinders, polishers and disc sanders". In this way, GB3883.3 should be included in the referenced standards. Although GB3883.1 is widely cited in GB3883.3, GB3883.1 is not directly cited in the enterprise standard of this product, so it is not listed in the referenced standards. 6.3 Basic parameters and types
6.3.1 Writing format
Basic parameters and types can be listed in chapters without paragraphs, or in chapters with paragraphs. When divided into paragraphs, they can generally be divided into "basic parameters and types" and "model meaning".
Basic parameters and types can be listed in a table. When writing enterprise standards for series products, a list is necessary. 6. 3.2 Contents and meanings of basic parameters and types The contents of basic parameters and types should generally include five parts: model specifications and types, power parameters, input parameters, output parameters, quality and external dimensions.

JB/T6235—1992
(Output parameters may be different for different product varieties.) Quality and external dimensions
External dimensions (use X, Y, and B instead of length, width, and height, (the external diagram may be attached as shown in Figure 1.)
Model specifications and types are naming regulations, and should be in accordance with relevant standards The name is specified. Type refers to the classification according to the type of electric shock protection, which is divided into Class 1, Class 1 and Class ", and the classification according to the degree of moisture resistance, which is divided into ordinary tools, splash-proof tools and watertight tools. The power supply parameters are the manufacturer's regulations on the use of power by users. The input parameters, output parameters, quality and dimensions are both the manufacturer's guaranteed values to users and the specified values. For example, the rated output power refers to the output power that can be guaranteed for users during normal use. For single-phase series-excited power tools, it refers to the output power that can be guaranteed under rated torque. This is the meaning of the guaranteed value; from the meaning of the specified value, it means that it should not be used at a power higher than this rated output power. Precisely because it is a guaranteed value and a specified value, it must be a definite value and cannot be written as greater than or equal to a certain value. And there is no need to specify whether it is not greater than or not less than, it can be understood according to general conventions. For example, the mass value is generally understood as not greater than this value. For example, the rated output power value is understood The above output parameters are applicable to general rotary power tools. For impact tools, the rated number of impacts should also be listed. Some should be indicated as the output power of the motor, etc. In addition.

The meaning of the model can be described in a list, and the typical terms are as follows: The model and meaning of this product are in accordance with GB9088. J1Z-LS2-13A
Class I ordinary type
J1Z-LS2-19AJ1Z-LS2-23A
Class I ordinary type
[Class I ordinary type
Then the various components of the model can be described (see GB9088), but when describing the design unit code, add brackets after it to indicate the name of the design unit.
6.4 Technical requirements
6.4.1. Principles for writing technical requirements
a. Technical requirements should not be lower than the general standards for products. Most technical requirements can be quoted from the general standards for products and should not be written repeatedly. b. Items available for selection in the general standards for products should be specific and affirmative in the enterprise standards for products, so they should be clearly listed. For example, insulation level and temperature rise limit.
When there are higher requirements than the general standards for products in the technical conditions, they should be clearly listed. Although some major quality indicators do not have higher requirements, they can also be clearly listed in order to enable readers to have a more comprehensive understanding of the quality indicators when reading this technical condition, such as noise. d. Whether there are limit requirements for radio and television interference levels is not clear in the general standards for products, but it is only proposed that when there are requirements, they should comply with the regulations, so the enterprise standards for products should be clarified. If there is no suppression requirement, it can be omitted in the enterprise standards for products, and it can also be omitted in the chapters of test methods and inspection rules. If the ability to suppress interference is possessed, it should be clearly listed. 6.4.2 Contents of technical requirements
Technical requirements can be composed of general requirements, safety requirements, appearance quality, noise, radio and television interference level, insulation level and temperature rise, basic parameters, etc., and each part can be clearly listed. . General requirements can refer to the general standards of products. The typical term is: the technical requirements of the product should meet the relevant provisions of the general standard of a certain product (specify the standard code and number) except for the provisions that have been supplemented and improved by the enterprise standard of this product. b. The provisions of safety requirements can be omitted because the safety requirements are already included in the general standard of the product. If the safety requirements are to be highlighted, they can also be listed. However, it should be noted that in the text description of the list, in addition to citing the corresponding safety standards, the supplemented and improved provisions in the general standard of the product should also be copied. If additional supplementary and improved items are required, they should also be described here. JB/T6235-1992
e, the basic parameters are listed in two parts, namely input power (or rated current) and basic parameters. The input power clauses can be written with reference to the corresponding clauses in the general product standards. Example 1: The measured input power of the electric drill under rated voltage and rated load should not be greater than 120% of the rated input power value. The clauses of basic parameters can be written with typical terms: the basic parameters meet the requirements of the table (i.e. the table in 6.3.2 Article 1). 6.5 Test methods
6.5.1 Principles for writing test methods
The items of technical requirements should generally be checked by corresponding test methods. The writing of test methods should adopt the method of citing standards as much as possible, without duplication. After listing the test method items, a clause of the remaining test methods can be listed to quote the relevant standards. The typical terms of this clause are as follows: The remaining test methods not specified in the enterprise standard of this product shall be written in accordance with XX (the corresponding product general standard code). If there is no corresponding product general standard, the safety standard can be directly quoted. 6.5.2 Test method items that generally need to be described in detail If the test items are not included in the referenced standards or the description of the included test items is not clear enough (such as under what conditions, whether it is no-load or load, or there is no requirement for running time, etc.), then in the test method chapter, they need to be described in detail. These items are generally: appearance inspection, noise test, input power and basic parameter measurement, quality measurement, appearance and size inspection, etc. 6.6 Inspection rules
All test items should be listed in this chapter, including test items that do not appear directly in the product enterprise standard due to the use of the writing method of the referenced standards. It is further divided into type test items (all test items) and inspection test items, and the conditions and rules for type testing are clearly defined. The writing method can refer to the relevant product general standards. 6.7 Marking, packaging, transportation, storage
"Marking" can be written with reference to the general product standards. "Packaging, transportation, storage" should be written in accordance with the relevant standards. 6.8 Others
The title and content of this article can be determined according to the specific situation and needs of the manufacturer, such as warranty period, spare parts, etc. Additional remarks:
This standard is proposed and managed by the National Electric Tool Standardization Technical Committee. This standard is drafted by the Shanghai Electric Tool Research Institute of the Ministry of Machinery and Electronics Industry, and the main drafter of this standard is Wang Zhenguo.
