本標(biāo)準(zhǔn)規(guī)定了教育機(jī)器人的基本安全要求、保護(hù)措施以及使用信息的要求和準(zhǔn)則。本標(biāo)準(zhǔn)適用于教育機(jī)器人。如果一個(gè)機(jī)器人由未成年人來(lái)組裝，本標(biāo)準(zhǔn)適用于可接觸的每個(gè)零件和組裝的機(jī)器人；如果一個(gè)機(jī)器人由成人(年滿18周歲)組裝或者在出廠時(shí)已經(jīng)組裝好，本標(biāo)準(zhǔn)適用于組裝的機(jī)器人。
本規(guī)范適用于新建、改建和擴(kuò)建的通信局（站）防雷與接地工程的設(shè)計(jì)。
本指導(dǎo)性技術(shù)文件描述低壓交流電源（≤100OV）中的浪涌電壓、浪涌電流環(huán)境，不包括其他的電能質(zhì)量問(wèn)題，如電壓跌落、電噪聲等。標(biāo)準(zhǔn)中所考慮的浪涌持續(xù)時(shí)間不超過(guò)半個(gè)工頻周期，這些浪涌可以是周期性的，也可以是隨機(jī)事件，可以出現(xiàn)在火線、零線以及地線之間。一般通過(guò)浪涌保護(hù)器（SPD）限制電壓和電流的幅值來(lái)分流危險(xiǎn)的浪涌能量，對(duì)于只會(huì)對(duì)設(shè)備造成干擾的浪涌一般采用其他方法消除。
本標(biāo)準(zhǔn)規(guī)定了航天器太陽(yáng)電池陣-蓄電池組電源系統(tǒng)的設(shè)計(jì)依據(jù)、設(shè)計(jì)原則、設(shè)計(jì)內(nèi)容、設(shè)計(jì)程序、設(shè)計(jì)方法和設(shè)計(jì)驗(yàn)證試驗(yàn)項(xiàng)目。本標(biāo)準(zhǔn)適用于航天器太陽(yáng)電池陣-蓄電池組電源系統(tǒng)(以下簡(jiǎn)稱電源系統(tǒng))的設(shè)計(jì)，其他種類電源系統(tǒng)的設(shè)計(jì)可參照使用。
本標(biāo)準(zhǔn)規(guī)定了通信安裝中緩解電磁故障的通用準(zhǔn)則，并給出案例分析提出了幾種解決EMC故障的方法，包括如何定位主要噪聲源和緩解的工具裝置。本標(biāo)準(zhǔn)適用于通訊安裝中的電磁故障。
For the interrelationships of this Recommendation with other ITU-T G.99x-series Recommendations, see [b-ITU-T G.995.1]. This Recommendation describes the interface between the telecommunication network and the customer installation in terms of their interaction and electrical characteristics. The requirements of this Recommendation apply to a single asymmetric digital subscriber line (ADSL).
The purpose of this Recommendation is to provide performance requirements for PTC thermistors to ensure their satisfactory operation in telecommunication networks. This Recommendation also covers coordination of these devices fitted in the MDF and the equ

1.1 These requirements cover manual signaling boxes for fire alarm systems intended for permanentinstallation and used in ordinary locations in accordance with the National Electrical Code, NFPA 70, and the National Fire Alarm Code, NFPA 72.1.2 A manual signaling box is an assembly of a mechanism having electrical contacts designed totransmit a signal when an integral part is operated manually. The signaling contacts are intended to beconnected to circuits of fire alarm systems. The types of boxes covered by these requirements are coded boxes and non-coded boxes, including signaling boxes, fire and guard’s tour reporting stations, and guard’s tour reporting stations for suppressed-signal tour combinations.1.3 A manual signaling box having a pre-wound signaling mechanism and equipped with a trippingelectromagnet to permit automatic actuation by separate detectors, and similar combination devices, shall be evaluated with regard to compliance with the applicable requirements for both manual signaling boxes and electrically-actuated transmitters.1.4 A manual signaling box shall be constructed for use with system-control units, electrically-actuatedtransmitters, or similar units that will permit its application in compliance with applicable codes andstandards of the National Fire Protection Association.1.5 These requirements do not cover electrically-actuated transmitters.
