本規(guī)范適用于采用纏繞、噴射和手糊工藝成型的整體纖維增強(qiáng)塑料設(shè)備和管道的設(shè)計、制造、安裝和工程質(zhì)量驗收。本規(guī)范不適用于下列纖維增強(qiáng)塑料設(shè)備和管道的設(shè)計:運輸槽罐、地埋容器、貯罐和雙壁罐;不規(guī)則形狀(非回轉(zhuǎn)體)的容器、貯罐和塔器;盛裝劇毒或放射性化學(xué)物質(zhì)的設(shè)備和管道;埋地給排水管道;煙囪和煙道;油氣田集輸管道。
YY 0989的本部分規(guī)定了適用于植入式心臟除顫器和用于具有治療快速性心律失常功能的有源植入醫(yī)療器械。本部分規(guī)定的試驗是型式試驗,通過對設(shè)備樣品的測試來確認(rèn)其符合性。本部分同樣適用于有源植入醫(yī)療器械的某些非植入式部分和附件(見注1)。植入式脈沖發(fā)生器或電極導(dǎo)線的特性應(yīng)通過本部分中列述的適當(dāng)方法或其他方法進(jìn)行驗證,其他方法的準(zhǔn)確度應(yīng)能被證明是等于或優(yōu)于規(guī)定的方法。如有爭議,應(yīng)采用本部分規(guī)定的方法。第2部分涵蓋了用于治療心動過緩的有源植入醫(yī)療器械的各個方面。
1.1 These requirements cover ballasts of the resistance, reactance, and electronic (high frequency) types for use with fluorescent lamps involving a potential of 2500 volts or less in accordance with the National Electrical Code, ANSI/NFPA 70.1.2 A fluorescent-lamp ballast may be determined by investigation to be acceptable for use, in a fixtureor other device, with electric-discharge lamps of other than the fluorescent type.1.3 Fluorescent self ballasted lamps and ballast adaptors are evaluated using the Standard forSelf-Ballasted Lamps and Lamp Adapters, UL 1993. The component ballast is evaluated to requirementsin this Standard.1.4 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shockor injury to persons shall be evaluated using appropriate additional component and end-productrequirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
This standard gives general instructions for carrying out microbiological examinations in accordance with specific standards. To help to ensure the validity of the examinations. To ascertain the general techniques used for conducting the examinations are the same in all labs. To help to achieve homogeneous results.
