JB/T 51096-1999

Manufacturers and quality inspection agencies in the tractor, internal combustion engine, agricultural transport, and construction machinery sectors use this standard to evaluate and grade alternator regulators. It provides a clear framework for classifying products as qualified, first-class, or premium, ensuring consistent quality assessment. This standard matters because it establishes uniform technical requirements and test methods, promoting product reliability and fair competition in the industry.

该标准主要用于拖拉机、内燃机、农用运输车和工程机械等领域的制造商和质检机构。他们依据此标准对交流发电机调节器进行质量等级评定，确保产品达到合格品、一等品或优等品的要求。该标准通过明确的分等指标和试验方法，为行业提供了统一的质量评价依据，有助于提升产品可靠性和市场竞争力。

This standard specifies quality grading indicators, test methods, and inspection rules for alternator regulators used in tractors and internal combustion engines. Regulators are classified into three grades: qualified, first-class, and premium, based on technical and quality levels. Detailed requirements are set for regulated voltage, durability, load dump performance, speed characteristics, load characteristics, high/low temperature performance, vibration/shock resistance, damp heat resistance, dust resistance, and installation appearance. The standard applies to quality inspection and grade evaluation of regulators in tractors, internal combustion engines, agricultural transport vehicles, and construction machinery, providing a unified basis for quality assessment in the industry.

本标准规定了拖拉机、内燃机用交流发电机调节器的产品质量分等指标、试验方法和检验规则。调节器按技术水平和质量分为合格品、一等品和优等品三个等级，并针对调节电压值、耐久性、抛负载性能、转速特性、负载特性、高低温性能、耐振动冲击、耐湿热、防尘及安装外观等多项指标设定了具体等级要求。标准适用于拖拉机、内燃机、农用运输车和工程机械等领域的调节器质量检测与等级评定，为行业提供了统一的质量评价依据。
