GB/T 3883.1-2014手持式、可移式電動工具和園林工具的安全 第1部分:通用要求

GB 3883的本部分涉及電動機或電磁鐵驅動的:--手持式電動工具(第2部分);--可移式電動工具(第3部分);--園林工具(第4部分)。以下簡稱“工具”。交流單相或直流工具的額定電壓不大于250 V,交流三相工具的額定電壓不大于440 V。大額定輸入功率不超過3 700 W。本部分涉及人們在正常操作以及合理可預見的使用工具時遇到的由工具引發的危險。帶電加熱元件的工具屬本部分范圍。這些加熱元件的要求在GB 4706的相關部分中規定。對于不與電網隔離、且基本絕緣由不按工具額定電壓設計的電動機,其要求在附錄B中規定。對于由可充電電池供電的電動機驅動或電磁鐵驅動的工具以及用于這些工具的電池包,其要求在附錄K中規定。對于能直接接在市電或非隔離電源上操作和/或充電的這類工具,其要求在附錄L中規定。不用對工具自身作任何改造便能夠安裝到一個支架或工作臺當作固定式工具使用的手持式電動工具屬于本部分范圍,由第3部分來規定。本部分不適用于:--在爆炸性環境(塵埃、蒸汽或氣體)中使用的工具;--制備和加工食品用工具;--醫療用工具;--與化妝品和藥品一起使用的工具;--加熱工具;--電動機驅動的家用或類似用途電器;--工業機床用電氣設備;--用來制作模型的由低壓變壓器驅動的小型臺式工具,如制作遙控飛機模型或汽車模型等。

UL 399-2008飲用水冷卻器

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含堿性或其他非酸性電解質的二次電池和電池組.便攜式密封二次電池和由其制成的便攜式電池的安全要求

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爆炸性氣體環境.\"n\"型保護電器裝置

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.
