法国NF金属及非金属材料标准名称

法国标准NF F 00-037 1993年9月存档编号F00－017前言本标准是一组有关金属零件公差的铁道标准的组成部分，该组标准包括两份标准：NF F 00-037 通用铁道设备－金属零件公差－无公差指示尺寸允许偏差－机加工余量NF F 00-038 通用铁道设备－金属零件公差－符合制造加工工艺的可获得的精度等级－机加工余量定义图明确规定了处于预定成品状态的零件必须满足的所有要求，这些要求是零件功能分析的结果，并且通过定义图或引用的连用文件中的标记，将使用合金的质量条件及形状，尺寸和表面状况说明规定。

尺寸是功能分析的结果，并且通常是图纸中作为含公差值的功能尺寸出现的最大和最小极限值，由该分析产生的工件尺寸因此应全部使用指定的可能最大公差范围，同时仍保持与预定功能的相容性。

应满足的功能要求涉及：－涉及组装的尺寸适合性条件通常取决于应遵守的有关空隙的极限值，在广义上术语“空隙”应要么被视作空隙，不确定空隙，要么被视作紧密度）；－非涉及组装的尺寸（强度、空间、质量、美学条件等）。

在第一种情况下，尽管功能要求提出了相对狭窄的公差范围，但在第二种情况下，可以以较宽的利用现役生产手段较易实现范围满足那些要求。

此外，在第二种情况下，和在非功能尺寸中，工件定义图的对应尺寸不含指定的个别的公值。

这时，使用的制造加工过程中固有的与规定尺寸的偏差后限于通用公差使，它们与当前的生产相符，但无需高成本的专用预防措施。

因此，本标准的目的是规定在定义图的有关尺寸上未标出公差值时零件尺寸应遵守的通用公差值。

但是，在必须执行高精度要求时，就应依据标准NF F00-038的规定确定该要求，这一标准按生产工艺规定了可实现的精度水平。

就模铸零件的允许偏差而言，本标准以试验标准A00－510为依据，该试验标准－取代了文件资料版本A31－011和A32－012；－与国际标准ISO8062等效，本身提供了表格UIC800 52的依据；－按模铸工艺和合金规定了模铸工件的机加工余量尺寸单位：mm目录前言1. 范围2. 适用条件3. 参考资料3.1 标准类参考资料3.2 非标准类参考资料4. 定义5. 记录斜面零件公差值的原则6. 模铸零件公值－机加工余量6.1 模铸零件公差值6.2 机加工余量7. 利用冲压锻制的钢零件或非铁金属或合金自由锻造零件的公差7.1 利用冲压锻制的钢零件7.2 非铁金属或合金自由锻造零件8. 金属板零件公差等级8.1 钢和非铁金属及合金的拉制零件8.2 切削零件8.3 锤击零件9. 焊接零件和氧气电弧切割零件的公差值9.1 钢、铝和铝合金焊接零件9.2 氧气电弧切割零件10. 机加工零件公差值10.1 线性尺寸10.2 角尺寸11.3 连接边和槽11.4 用于固定设备的冲孔或钻孔1. 范围本标准按行业使用的生产手段规定了铁道设备结构目前需要的通用公差值。

厦门易朔Ecosafene公司NFP92-507防火测试法国M等级NF P92-503，NFP92-501防火测试相关新闻：随着建筑节能工作的深入开展，我国建筑保温材料行业迎来了难得的发展机遇。

不论是技术的创新、产业的融合与升级，还是解决市场、技术、标准、政策等方面存在的问题，都需要集全行业的力量，共同努力。

在推广交流会上，记者获悉，由住房和城乡建设部科技与产业化发展中心发起的、以技术创新和产业化创新为宗旨的中国绿色建材产业化创新联盟经过紧张筹备，即将成立，这对于我国绿色建材产业与绿色建筑产业的协调健康发展是一个好消息。

标准概述：法国政府于2002年11月颁布的条例第3章，以装饰装修材料对火反应特性为依据，定义其级别划分的标准。

NFP92-503 该法规包含建筑和装饰材料防火性能测试方法。

NF P 92-503对防火测试分为M0到M4级，M0为最高等级。

按M1至M4的标准，将各种厚度的硬质材料与厚度超过5毫米的软质材料的燃烧性能进行分级，其依据是NF P 92-501辐射热源试验所得结果。

11．概述1.1 对象该标准介绍了钢铁产品的布氏硬度试验并说明了其应用方法。

1.2 参考标准NF A 03-154 《冶金产品–钢铁的维氏硬度试验（载荷为5kgf到100kgf）》。

NF A 03-502 《冶金产品–布氏硬度试验机器的检验》。

NF A 03-505 《冶金产品–布氏硬度试验–硬度参考块的标定》。

NF A 95-422 《冶金产品–硬金属–维氏硬度试验（载荷为98,1到491N）》。

2．试验原理2.1 该试验即在载荷F下将一个直径为D的钢珠或碳化钨珠压印到试验零件中，然后测定去掉载荷后留在表面上的型腔的平均直径d。

2.2 布氏硬度即与试验载荷F的商数成正比的一个数，以牛顿比平方毫米表示，对应球面直径为D的球冠形型腔的面积。

该硬度应由最接近所得商数的整数来表示。

其比例系数为0,102，可根据下列方程获得布氏硬度：布氏硬度根据珠子的属性布氏硬度的符号分别是：- 通过钢珠完成的试验对应符号为HBS。

- 通过碳化钨珠完成的试验对应符号为HBW。

3．应用范围布氏硬度试验的应用范围取决于用作钻头的珠子属性：- 钢珠：试验仅适用于450以下的布氏硬度。

- 碳化钨珠：试验适用于布氏硬度650以下的所有硬度范围。

每种珠子都对应一个硬度级。

对于超过350的布氏硬度这两种级别是不同的。

4．硬度的符号，定义和表示4.1 符号和定义下面的表1中列举了各项符号和定义：中的规定一致的一批珠子中选择新的珠子。

然后在的温度下通过一台精度为的测量装置检验珠子的直径。

5.2.1 钢珠这种珠子必须采用淬火钢制造并具备根据NF A 03-154标准所测定的不小于850 HV 10的维氏硬度。

表2中提供了在98,07牛的载荷在根据钢珠曲率所得维氏型腔的平均对角线最大值。

5.2.2 碳化钨珠这种珠子必须选用碳化钨制造，其化学成分如下：- 碳化钨94%- 钴6%其比重为。

这种珠子必须具备根据NF A 95-422标准所测定的不小于1500 HV 10的维氏硬度。

各国质量认证标志及说明1. CE认证(Conformite Europeenne) 这个标志想必大家都非常熟悉吧!对,它就是CE认证,使用CE认证的产品越拉越广,某产品中如果有CE标志的话,就代表这件产品安全、卫生、环保和消费者保护等一系列欧洲指令所要表达的要求。

如果产品可以符合相关的要求，就可以贴CE标志了，但不符合相关的要求，就与之相反。

(个人觉得CE不是认证，只是自我申明而已，一般出货欧洲会做此声明)C产品认证（China compulsory certification） CCC认证：所谓3C认证，这个认证是2002年5月1日诞生的，CCC是英文China compulsory certification 的缩写，意思是“中国强制认证”。

如果产品被列入国家质量监督检验检疫总局和国家认证认可监督管理委员会发布的《第一批实施强制性产品认证的产品目录》，就要对该产品实施强制性的检测和审核。

如果是列入目录里的产品，没获得指定机构认证的，没进行按规定标贴认证的，就不可以销售、进口和出厂了。

这个标志实施以后，就取代了原本的“长城”标志，“长城”标志自2003年5月1日起就作废了。

需要注意的是，3C标志并不是质量标志，而只是一种最基础的安全认证。

3.CQC认证 中国质量认证中心（CQC），可以获得CQC的认证，再贴上CQC认证标志的产品，就是被国家级认证机构认证的，认证目的为安全的、符合国家响应的质量标准。

4.CB认证 CB体系（电工产品合格测试与认证的IEC体系）是IECEE运作的－个国际体系，IECEE各成员国认证机构以IEC标准为基础对电工产品安全性能进行测试，其测试结果即CB测试报告和CB测试证书在IECEE各成员国得到相互认可的体系。

目的是为了减少由于必须满足不同国家认证或批准准则而产生的国际贸易壁垒。

IECEE 是国际电工委员会电工产品合格测试与认证组织的简称。

5.PCT认证 “要进入俄联邦海关领土的产品都必须要获得俄罗斯国家标准计量委员会颁发的国家标准合格证书（GOST合格证）”俄罗斯中的法律这样规定到。
