本标准规定了电子陶瓷名词术语的定义.包括基础理论、瓷料种类、性能与测试、设备和工艺及其它,共五部分。
本标准规定了水声常用压电陶瓷元件的技术要求、试验方法、检验规则、标志、包装、运输和贮存。 本标准适用于P-41、P-51、P-81三种压电陶瓷材料的圆片、中孔圆片、径向极化圆管和矩形板四种形状的压电陶瓷元件。
本标准规定了被银陶瓷零件的要求、试验方法、检验规则、标志、包装、运输和贮存。 本标准适用于用烧渗法在陶瓷上被覆银层,用电镀法加厚的银铜层和用软焊料热浸(涂)锡的银-锡层、银-铜-锡层的被银陶瓷零件。
本标准适用于以低碳钢、不锈钢等金属为芯板、表面被覆一层瓷釉的混合集成电路用被釉钢基片。
本规范规定了电波暗室等使用的、采用RN2K5镍铜锌软磁铁氧体材料制成的铁氧体吸收体(以下简称吸收体)的术语和定义、要求、检验规则、试验方法、包装、贮存和运输等。本规范适用于采用RN2K5镍铜锌软磁铁氧体材料制成的烧结型吸收体。
本标准规定了真空电子器件专用93%氧化铝陶瓷的定义、性能要求、试验方法、检验规则、标志、包装、运输和贮存等。本标准适用于真空电子器件装置瓷体及装置零件等用的氧化铝质量分数为(93±0.5) %氧化铝陶瓷(93%氧化铝瓷)。其他领域使用的结构工程用93%氧化铝陶瓷可参照使用。
This International Standard applies to stand-alone indicator light units intended to give a visible signal. They are designed for a.c. only with a rated voltage not exceeding 440 V and a rated power not exceeding 10 W, for household and similar fixed-electrical installations, either indoors or outdoors.\nNOTE 1 Indicator light units are not intended for lighting as a luminaire (see IEC 60598).\nThis standard does not apply to pilot lights incorporated in products complying with their own standards which are tested as part of that product.\nThe standard also applies to boxes for indicator light units, with the exception of flush-mounting boxes (according to IEC 60670) for flush-type indicator light units.\nIndicator light units complying with this standard are suitable for use at ambient temperatures not normally exceeding 25 ℃, but occasionally reaching 35 ℃.\nIn locations where special conditions prevail, as in ships, vehicles and the like and in hazardous locations, for example where explosions are liable to occur, special constructions may be required.\nNOTE 2 LEDs and lamps are not considered as indicator light units, but as components.
