欧标EN 10002-5:1992 金屬材料高温测试方法

作者：來源：发布日期： 2020.10.19

信息摘要：

欧标EN 10002-5:1992 金屬材料高温测试方法

欧洲标准 EN 10002-5:1992 金屬材料；拉伸试验；高温下的测试方法

EN 10002 由五个部分组成：
——第一部分：金屬材料；拉伸试验；实验方法（室温）
——第二部分：金屬材料；拉伸试验；拉伸实验机测力系统的校正
——第三部分：金屬材料；拉伸试验；用于单轴实验机校正的力检验设备的校准
——第四部分：金屬材料；拉伸试验；用于单轴实验机的变形测定器的校准
——第五部分：金屬材料；拉伸试验；高温下的测试方法

1 范围

该欧洲标准指定金屬材料拉伸实验的方法并定义其高温下的机械性能。对某种特定金屬材料及应用，拉伸试验可能受具体的标准或者特定要求的约束。必须注意试验根据室温下测试方法（EN 10002/1）在相同的温度下的执行，并且此标准应当根据不同试验条件给定不同结果，譬如加载速率（见附录G）。

兩試驗操作條件的設定應當根據其相對應標准的下一修訂本。

2 参考标准

EN 10002-1, 金屬材料——拉伸试验——第一部分：室温下的测试方法

EN 10002-2, 拉伸试验——拉伸实验机测力系统的校正

ISO 2566-1，钢——拉伸变化值—— 第一部分：碳钢与合金钢

ISO 2566-2，钢——拉伸变化值—— 第二部分：奥氏体钢

EN 10002-4，金屬材料——用于单轴实验机的变形测定器的校准

EU 18-1979，试样的选择及准备和钢及铁及钢材的试样

3 原理

在規定溫度下，對試樣施加拉力，一般拉伸至斷裂，根據條款4中定義的一項或幾項拉伸力學性能。

4 试验设备

試驗機

試驗機的校准必须按EN 10002-2校准，并且等级为1级或更好。

引伸計

当使用引伸計测量伸长时，对于上、下屈服强度及规定非比例延伸强度，应使用不劣于1级（EN 10002-4）准确度的引伸計；当测量试样的非比例延伸强度及有较大延伸率性能时，可使用不劣于EN 10002-4中2 级准确度的引伸計。引伸計标距应不小于10mm，并置于试样平行长度的中间部位，建议优先采用能测量试样两个侧面伸长的双面引伸計。
注意引伸計伸出加热装置外部分的设计应能防止气流的干扰，以使环境温度的变化对引伸計的影响减至最小。最好保持試驗機周围的温度和空气流动速度适当稳定。

"And sure," she said, "and I hope that wretched old Feejee won't be in Japan at all, at all, and the horrid haythens won't roast him." THIRD-CLASS PASSENGERS. THIRD-CLASS PASSENGERS. I was about to put a false meaning even on that, when she added "We don't need the ford this time of year; let us ride back as if we gave up the trip--for there may be a vidette looking at us now in the edge of those bushes--and as soon as we get where we can't be seen let us take a circuit. We can cross the creek somewhere above and strike the Wiggins road up in the woods. You can find your way by the blessed stars, can't you--being the angel you are?" "Good-night, gentlemen," said the doctor at last. As he passed into the darkness Quinn bent a mock frown upon his young superior. It would require a mathematical diagram to describe the incident with absolute accuracy. The Curate, of course, had heard nothing about the Clockwork man's other performances; he had scarcely heeded the hints thrown out about the possibility of movement in other dimensions. It seemed to him, in the uncertain light of their surroundings, that the Clockwork man's right arm gradually disappeared into space. There was no arm there at all. Afterwards, he remembered a brief moment when the arm had begun to grow vague and transparent; it was moving very rapidly, in some direction, neither up nor down, nor this way or that, but along some shadowy plane. Then it went into nothing, evaporated from view. And just as suddenly, it swung back into the plane of the curate's vision, and the hand at the end of it grasped a silk hat. Good fitting is often not so much a question of skill as of the standard which a workman has fixed in his mind, and to which all that he does will more or less conform. If this standard is one of exactness and precision, all that is performed, whether it be filing, turning, planing, or drawing, will come to this standard. This faculty of mind can be defined no further than to say that it is an aversion to whatever is imperfect, and a love for what [171] is exact and precise. There is no faculty which has so much to do with success in mechanical pursuits, nor is there any trait more susceptible of cultivation. Methodical exactness, reasoning, and persistence are the powers which lead to proficiency in engineering pursuits. I was the only civilian in that road, and the soldiers, with much curiosity, stared at me. Whenever I noticed an officer, I gave an elaborate military salute, and with such an air that the officers, although hesitating at first, did not fail to return the salute. The reformed system of education was to be not only moral and religious but also severely scientific. The place given to mathematics as the foundation of a right intellectual training is most remarkable, and shows how truly Plato apprehended the conditions under which knowledge is acquired and enlarged. Here, as in other respects, he is, more even than Aristotle, the precursor of Auguste Comte. He arranges the mathematical sciences, so far as they then existed, in their logical order; and his remarks on the most general ideas suggested by astronomy read like a divination of rational mechanics. That a recommendation of such studies should be put into the mouth of Socrates is a striking incongruity. The older Plato grew the farther he seems to have advanced from the humanist to the naturalistic point of view; and, had he been willing to confess it, Hippias and Prodicus were the teachers with whom he finally found himself most in sympathy. We are told that when his end began to approach, the dying philosopher was pressed to choose a successor in the headship of the School. The manner in which he did this is289 characteristic of his singular gentleness and unwillingness to give offence. It was understood that the choice must lie between his two most distinguished pupils, Theophrastus of Lesbos, and Eudêmus of Rhodes. Aristotle asked for specimens of the wine grown in those islands. He first essayed the Rhodian vintage, and praised it highly, but remarked after tasting the other, ‘The Lesbian is sweeter,’ thus revealing his preference for Theophrastus, who accordingly reigned over the Lyceum in his stead.179 Abibulla saw them off with great deference and a contrite air, and watched their retreat; then, as[Pg 260] I was about to send him to despatch the message, he was indignant. The police! What could they do to a sahib like me? It was all very well to frighten poor folks—it was a sin to waste money in asking for a reply which I should never be called upon to show—and so he went on, till I made up my mind to think no more of the matter. And whenever I met the chief at the bazaar or by the Jellum, he only asked after my health and my amusements. Felipa shook her head at Ellton. "Don't get yourself excited about it, Jack dear," she soothed, and Ellton also tried to quiet him. The last straw was laid on when an Indian policeman arrested a young buck for some small offence. The buck tried to run away, and would not halt when he was told to. The chief of police fired and killed a squaw by mistake; and though he was properly sorry for it, and expressed his regret, the relatives and friends of the deceased squaw caught him a few days later, and cutting off his head, kicked it round, as they had seen the White-eye soldier do with his rubber foot-ball. Then they, aroused and afraid too of punishment, fled from the reservation and began to kill. "Yes," he assured her unmoved, "you are. At least you are going to do that, or go to jail." The poor man looked as miserable as if put in a strait-jacket, but tried to literally obey instructions. "Probably it was Corpril Elliott's good management," suggested Gid Mackall, whose hero-worship of Shorty grew apace. "I tell you there aint a trick o' soldierin' that he aint up to." Then suddenly she was silent—and Reuben kissed her. "You finish your tea," he said to George, "and bring some more, Maudie, for these gentlemen," nodding kindly to the two young men, who stared at him as if they thought he had taken leave of his senses.
