本標(biāo)準(zhǔn)規(guī)定了鋼鐵熱浸鍍鋁工藝要求和熱浸鍍鋁層質(zhì)量檢驗(yàn)方法。本標(biāo)準(zhǔn)適用于耐熱耐腐蝕要求的鋼鐵結(jié)構(gòu)制品。不適用于連續(xù)式生產(chǎn)的熱浸鍍鋁薄板、帶材和線材制品。
GB/T 19355的本部分給出了適用于鋼鐵結(jié)構(gòu)件防腐蝕保護(hù)用熱浸鍍鋅一般準(zhǔn)則的指南和建議。熱浸鍍鋅層對(duì)結(jié)構(gòu)件的保護(hù)取決于所采用的鍍覆方法、結(jié)構(gòu)件的設(shè)計(jì)和結(jié)構(gòu)件的具體使用環(huán)境。采用附加涂層(GB/T 19355的本部分范圍之外的涂層),如有機(jī)涂層(涂料和粉末涂層)可以進(jìn)一步提高熱浸鍍鋅結(jié)構(gòu)件保護(hù)性能。附加涂層與熱浸鍍鋅聯(lián)合使用形成的涂層,稱(chēng)為“復(fù)合涂層體系”。GB/T 19355本部分的指南和建議不涉及鋼鐵熱浸鍍鋅層服役過(guò)程中的防腐蝕維修,相關(guān)項(xiàng)目指南見(jiàn)ISO 12944-5規(guī)定。
本標(biāo)準(zhǔn)規(guī)定了建筑幕墻的術(shù)語(yǔ)和定義、分類(lèi)、標(biāo)記;通用要求和專(zhuān)項(xiàng)要求、試驗(yàn)方法、檢驗(yàn)規(guī)則、標(biāo)志、包裝、運(yùn)輸與貯存 本標(biāo)準(zhǔn)適用于以玻璃、石材、金屬板、人造板材為飾面材料的構(gòu)件式幕墻、單元式幕墻、雙層幕墻,還適用于全玻幕墻、點(diǎn)支承玻璃幕墻。采光頂、金屬屋面、裝飾性幕墻和其他建筑幕墻可參照使用 本標(biāo)準(zhǔn)不適用于混凝土板幕墻、面板直接粘貼在主體結(jié)構(gòu)的外墻裝飾系統(tǒng),也不適用于無(wú)支承框架結(jié)構(gòu)的外墻干掛系統(tǒng)
本標(biāo)準(zhǔn)規(guī)定了高桿照明設(shè)施的產(chǎn)品分類(lèi)和型號(hào)、一般要求、要求、試驗(yàn)方法、檢驗(yàn)規(guī)則以及標(biāo)志、包裝、運(yùn)輸和貯存等。本標(biāo)準(zhǔn)適用于燈桿高度大于或等于20 m且小于或等于50 m,作為城市道路、公路、廣場(chǎng)、體育場(chǎng)、機(jī)場(chǎng)、港口碼頭等大面積照明的高桿照明設(shè)施。
本規(guī)范適用于非抗震設(shè)計(jì)和抗震設(shè)防烈度為6、7、8度抗震設(shè)計(jì)的民用建筑玻璃幕墻工程的設(shè)計(jì)、制作、安裝施工、工程驗(yàn)收,以及保養(yǎng)和維修。
本標(biāo)準(zhǔn)規(guī)定了輸電線路鐵塔(簡(jiǎn)稱(chēng)“鐵塔”)的腐蝕評(píng)估要求,以及防腐蝕保護(hù)涂裝的技術(shù)要求,檢驗(yàn)要求,試驗(yàn)方法,安全、衛(wèi)生和環(huán)境保護(hù)要求。本標(biāo)準(zhǔn)適用于新建和在役鐵塔在設(shè)計(jì)、制造、安裝、運(yùn)維各階段的防腐蝕保護(hù)涂裝相關(guān)工作,水泥混凝土桿的鋼箍、橫擔(dān)等類(lèi)似鋼結(jié)構(gòu)也可參照?qǐng)?zhí)行。本標(biāo)準(zhǔn)適用于以下涂裝工藝形成的金屬涂層和非金屬涂層:熱浸鍍、熱噴涂及其封閉涂料層、涂料涂裝。
Proposal to revise requirements for the Conduit Identification marking (delete private labeler information).
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.
The following items are subject to comment: 1.) Correction of test references in Table 18.1. 2.) Addition in paragraph 40.1.1 of equation for limit voltage (VL).
