标准摘要
[中文适用范围]: ISO 898的这一部分规定了由碳钢或合金钢制成的紧定螺钉和类似螺纹紧固件在10°C至35°C的环境温度范围内测试时的机械和物理性能。 符合 ISO 898 本部分要求的紧固件(当紧定螺钉和类似螺纹紧固件一起考虑时使用的术语)在该环境温度范围内进行评估。 符合 ISO 898 这一部分的紧固件被分类为指定的硬度等级,并且仅用于在压缩应力下使用。 注:符合 ISO 898 本部分要求的紧固件适用于 -50 °C 至 +150 °C 的应用。 在为给定应用确定适当的选择时,用户有责任咨询经验丰富的紧固件冶金学家,了解 -50 °C 至 +150 °C 范围之外的温度以及最高 +300 °C 的最高温度。 ISO 898的本部分适用于紧定螺钉和类似的螺纹紧固件: ——由碳钢或合金钢制成, — 具有符合ISO 68-1的三角形ISO公制螺纹, — 具有M1,6的粗牙螺纹至 M30,以及 M8×1 至 M30×2 的细牙螺纹, — 直径/螺距组合符合 ISO 261 和 ISO 262,并且 — 螺纹公差符合 ISO 965-1 和 ISO 965-2。 它没有规定以下性能的要求: ——拉伸强度, — 剪切强度, — 可焊性, — 耐腐蚀性,或 — 承受高于 +150 °C 或低于 -50 °C 温度的能力。 [外文原描述]: ISO 898-5:2012 specifies mechanical and physical properties of set screws and similar threaded fasteners made of carbon steel or alloy steel when tested at an ambient temperature range of 10 °C to 35 °C. Fasteners (the term used when set screws and similar threaded fasteners are considered all together) which conform to the requirements of ISO 898-5:2012 are evaluated at that ambient temperature range. Fasteners according to ISO 898-5:2012 are classified to specified hardness classes and are intended for use under compressive stress only. ISO 898-5:2012 is applicable to set screws and similar fasteners: made of carbon steel or alloy steel, having a triangular ISO metric screw thread according to ISO 68-1, with a coarse pitch thread M1,6 to M30, and fine pitch thread M8×1 to M30×2, with diameter/pitch combinations according to ISO 261 and ISO 262, and having thread tolerances according to ISO 965-1 and ISO 965-2.
