GB/T 3883.1-2014手持式、可移式电动工具和园林工具的安全 第1部分:通用要求

GB 3883的本部分涉及电动机或电磁铁驱动的:--手持式电动工具(第2部分);--可移式电动工具(第3部分);--园林工具(第4部分)。以下简称“工具”。交流单相或直流工具的额定电压不大于250 V,交流三相工具的额定电压不大于440 V。大额定输入功率不超过3 700 W。本部分涉及人们在正常操作以及合理可预见的使用工具时遇到的由工具引发的危险。带电加热元件的工具属本部分范围。这些加热元件的要求在GB 4706的相关部分中规定。对于不与电网隔离、且基本绝缘由不按工具额定电压设计的电动机,其要求在附录B中规定。对于由可充电电池供电的电动机驱动或电磁铁驱动的工具以及用于这些工具的电池包,其要求在附录K中规定。对于能直接接在市电或非隔离电源上操作和/或充电的这类工具,其要求在附录L中规定。不用对工具自身作任何改造便能够安装到一个支架或工作台当作固定式工具使用的手持式电动工具属于本部分范围,由第3部分来规定。本部分不适用于:--在爆炸性环境(尘埃、蒸汽或气体)中使用的工具;--制备和加工食品用工具;--医疗用工具;--与化妆品和药品一起使用的工具;--加热工具;--电动机驱动的家用或类似用途电器;--工业机床用电气设备;--用来制作模型的由低压变压器驱动的小型台式工具,如制作遥控飞机模型或汽车模型等。

UL 399-2008饮用水冷却器

1.1 These requirements cover self-contained drinking-water coolers which employ hermetic refrigerantmotor-compressors and which are designed for connection to alternating-current circuits rated not greaterthan 600 volts in accordance with the National Electrical Code, NFPA 70. The requirements also apply towater coolers which supply both hot and cold water.1.2 These requirements do not include additional requirements applicable to equipment designed for usein hazardous locations as defined in the National Electrical Code, NFPA 70.1.3 A product that contains features, characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this standard, and that involves a risk of fire, electric shock, orinjury to persons shall be evaluated using the appropriate additional component and end-productrequirements as determined necessary to maintain the acceptable level of safety as originally anticipatedby the intent of this standard. A product whose features, characteristics, components, materials, orsystems conflict with specific requirements or provisions of this standard cannot be judged to comply withthis standard. Where considered appropriate, revision of requirements shall be proposed and adopted inconformance with the methods employed for development, revision, and implementation of this standard.

GSO IEC 62133-2014含碱性或其他非酸性电解质的二次电池和电池组.便携式密封二次电池和由其制成的便携式电池的安全要求

NEW! IEC 62133:2012 is available as IEC Standards+ 62133:2012 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 62133:2012 specifies requirements and tests for the safe operation of portable sealed secondary cells and batteries (other than button) containing alkaline or other non-acid electrolyte, under intended use and reasonably foreseeable misuse. This edition includes the following significant technical changes with respect to the previous edition: - update of assembly of cells into batteries (5.5); - addition of design recommendations for lithium system only (5.6.2); - separation of nickel systems and lithium systems (Clause 6); - addition of specific requirements and tests for lithium systems (Clause 8); - addition of charging of secondary lithium-ion cells for safe use (Annex A). The contents of the corrigendum of June 2013 have been included in this copy.

BS EN 60079-15-2010爆炸性气体环境.\"n\"型保护电器装置

This part of IEC 60079 specifies requirements for the construction, testing and marking forGroup II electrical equipment with type of protection, \"n\" intended for use in explosive gasatmospheres. This standard applies to electrical equipment where the rated voltage does notexceed 15 kV r.m.s. a.c. or d.c.This part of IEC 60079 is applicable to non-sparking electrical equipment and also toelectrical equipment with parts or circuits producing arcs or sparks or having hot surfaceswhich, if not protected in one of the ways specified in this standard, could be capable ofigniting a surrounding explosive gas atmosphere. This standard describes several differentmethods by which this can be achieved which may be combined with other methods describedin IEC 60079-0.This standard supplements and modifies the general requirements of IEC 60079-0, except asindicated in Table 1. Where a requirement of this standard conflicts with a requirement ofIEC 60079-0, the requirement of this standard takes precedence.
