本标准规定了在高温、高空气流量的极端条件诱导下油脂氧化稳定性的测定方法。本标准适用于未精炼的和精炼的动植物油脂。本标准不适用于常温下油脂稳定性的测定,但可用于比较添加到油脂中的抗氧化剂的抗氧化效率。注:挥发性脂肪酸及不稳定的酸性氧化产物的存在影响测量结果的准确性。
GB/T 21204的本部分规定了在严酷环境下使用时对绞或星绞多芯对称电缆的定义和试验方法,这种电缆用于数字通信系统,如综合业务数字网(ISDN)、局域网和数据通信系统。本部分是这类电缆的设计和试验的导则
本标准规定了挥发性有机化合物(VOC)单位面积上释放量和/或在指定环境条件下气态VOC浓度测定的常规检测方法。本标准对检测用弹性铺地物、纺织铺地物和层压板铺地物挥发性有机化合物释放量检测舱进行了阐述。附录A对释放量检测舱进行了描述,附录B给出了评价系统示例。检测舱对未使用(铺设之前)铺地物产品的挥发性有机化合物释放量进行检测,在检测前和检测过程中都需要对待检试样进行处理。对于不同的铺地物产品,取样、运输和贮藏程序都有详细的规定,因其会影响试验数据,对于每种待检产品,规定应设有备样。
This European Standard specifies:the dimensional,mechanical,hydraulic and acoustic characteristics with which flow rate regulations should comply;the procedures for testing these characteristics. This European Standard is applicable to:flow rate regulators intended to be mounted on tapware used with sanitary appliances in toilets,washrooms and kitchens(single taps,combination tap assemblies,mechanical mixing valves,thermostatic mixing vavles);flow rate regulators used under the flowing pressure and temperature conditions.Flow rate regulators can only be connected downstream of the obturator of the top.
This standard specifies requirements for flow rate regulators used for sanitary tapware .
This European Standard aims to establish:— the dimensional, hydraulic and acoustic properties to which flow rate regulators intended to be mounted on sanitary tapware shall correspond;— the test methods whereby these properties may be verified.

This European Standard specifies: a) the field of application for pillar taps, bib taps, single and multi-hole combination taps for use in: 1) a supply system of Type 1 (see Figure 1); 2) a supply system of Type 2 (see Figure 2); b) the dimensional, leaktightness, pressure resistance, hydraulic performance, mechanical strength, endurance and acoustic characteristics of nominal size 1/2 and 3/4 single taps and combination taps; c) test methods to verify the characteristics. The tests described in this European Standard are type tests (laboratory tests) and not quality control tests carried out during manufacture.) This European Standard applies to draw-off taps (single taps and combination taps) for use with sanitary appliances installed in rooms used for bodily hygiene (cloakrooms, bathrooms etc.) and in kitchens, i.e. for use with baths, wash basins, bidets, showers and sinks. Figure 1 shows a supply system of Type 1 with a pressure range of (0,05 to 1,0) Mpa [(0,5 to 10) bar]. Figure 2 shows a supply system of Type 2 with a pressure range of (0,01 to 1,0) Mpa [(0,1 to 10) bar]. This European Standard applies to sanitary draw-off taps of nominal size 1/2 and 3/4 (PN 10). The conditions of use and classifications are given in Table 1. The Table 2 gives the performance characteristics to be noted if the tap is used outside the recommended operating range.
This European Standard specifies:\n— the dimensional, mechanical, hydraulic and acoustic characteristics with which flow rate regulators should comply;\n— the procedures for testing these characteristics. This European Standard is applicable to:\n— flow rate regulators intended to be mounted on tapware used with sanitary appliances in toilets, washrooms and kitchens (single taps, combination tap assemblies, mechanical mixing valves, thermostatic mixing valves);\n— flow rate regulators used under the following pressure and temperature conditions:\nFlow rate regulators can only be connected downstream of the obturator of the tap.
Diese Europäische Norm gilt für Strahlregler, die an Armaturen zur Ausrüstung von Sanitärgegenstanden angeschlossen werden, die in Räumen für die Hygiene und Küchen eingebaut sind (Auslaufventile, Mischbatterien, mechanisch gesteuerte Mischer.. ).
