GB17498—1998
This standard adopts EN957-1:1996 "Stationary training equipment Part 1: General requirements and test methods" in a non-equivalent manner, and is formulated in combination with the actual production conditions of my country's fitness equipment industry. The main technical differences between this standard and EN957-1:1996 are as follows: 1. The term "stay" replaces "wire (rope), steel belt" in the original standard; 2. The opening in the pulley structure diagram is replaced by "maximum 52°\" instead of "52°±1"; since the process design specification of the fitness equipment production industry in my country stipulates that the opening of the pulley groove is 36°~52°, in order to meet the "maximum 52°" of the pulley groove opening and make the inner surface of the groove smooth (tangent) to avoid wear on the stay, the requirement of 120°±1° fillet at the bottom of the groove is cancelled; 3. For the metal clamp to clamp the stay, the clamping force test requirements of the stay clamp are supplemented, which are parallel to the requirements in the original standard. One of the requirements can be selected to adapt to the several forms of metal clamps used in my country's production industry. 4. In this standard, the angle between the stay and the cover is at least 50°, or other corresponding measures are used to ensure safety, and the requirement of 120°±1° fillet is cancelled. The flywheel test in the original standard has been replaced.
In order to further standardize the production, sales and use of fitness equipment, a series of relevant industry standards with "fitness equipment" as the main title will be gradually formulated in the future, including the definition of fitness equipment, product classification, general technical conditions, inspection rules and specific product standards of various types. This standard is proposed by the State Bureau of Light Industry.
This standard is under the jurisdiction of the National Center for Standardization of Stationery and Sports Goods. The responsible drafting units of this standard are: Shanghai Stationery and Educational Goods Industry Research Institute, Huzhou Fitness Equipment Factory, and Shanxi Changzhi Aorui Special Fitness Equipment Factory; participating drafting units: National Sports Commission Sports Equipment Center, National Sports Equipment Quality Inspection Center. The main drafters of this standard are: He Yuling, Yuan Tianxiang, and Wu Shaodi. 327
