爲了安全監察，更爲了企業長遠和健康的發展。保證化工行業安全生産，是每個個體義不容辭的責任和義務。尤其對各個石化企業來說，樹立安全理念，做好事故防範措施是生産工作的首要前提。如何將這一系列的災難和後果控制得更少或者在可以接受的範圍內呢？

爲此，SIL認證應運而生。事實上，設備的故障發生在産品生命周期的各個階段，只是發生概率不同而已。 SIL認證就是在産品設計之初就介入，按照一定的標准和成熟規範對産品整個生命周期進行可控性管理，使得故障的發生可能性降到更低。從而達到控制風險的目的。

SIL認證對流量計産品的積極影響：

1、可以保證産品特定功能的正確性；

2、可以提高産品在行業的接受程度和認可度；

3、由于認證的産品具有較高的安全性，提高了産品的競爭力；

4、客戶通常認爲：經過認證的=獲得承認的 =優質的。

SIL認證對企業的積極影響：

1、提高企業安全經驗和安全水平；

2、對未認證的同行有明顯的競爭優勢；

3、企業研發過程更加規範並且可以驗證；

4、傷害發生時，在制度上有更高的安全保障；

5、在整個認證過程中，保證企業研發水平保持在較高水准。

如果一個項目、一個系統或産品獲得了SIL的認證，其産品質量和安全性也就獲得了承認和認可，在提升企業的市場競爭力的同時，也極大地增強了客戶對産品的信心。所以，如果一個産品對生命財産安全影響較大的話，進行 SIL認證就非常必要。

那麽，SIL認證是什麽？

SIL(Safety Integrity Level)即安全完整性等級。SIL认证是基于 IEC 61508（ GB/T 20438）, IEC 61511(GB/T 21109), IEC 61513, IEC13849-1, IEC 62061, IEC 61800-5-2 等標准，對安全設備的安全完整性等級(SIL) 或者性能等級(PL)進行評估和確認的一種第三方評估、驗證和認證。功能安全認證主要涉及針對安全設備開發流程的文檔管理 (FSM)評估，硬件可靠性計算和評估、軟件評估、環境試驗、 EMC電磁兼容性測試等內容。

安全相關系統的SIL應該達到哪一級別，是由風險分析得來的，即通過分析風險後果嚴重程度、風險暴露時間和頻率、不能避開風險的概率及不期望事件發生概率這四個因素綜合得出。級別越高要求其危險失效概率越低。

近幾年，化工安全事故頻發，衆人“談化色變”。在化工生産運行中，對于設備的安全性要求應當高度重視。

青天儀表多款産品取得SIL認證證書，體現了公司産品質量已經符合了國際安全標准，標志著公司産品已經達到了石化工藝生産過程中對儀表類産品安全性要求高的標准！

‘Are you going home?’ asked the other. ‘My wife, I know, is calling on Lady Keeling, and she will pick me up there. If she has not been so fortunate as to find Lady Keeling in, she will wait for me in the motor. May we not walk down there together?’ ‘My dear,’ he said, ‘I am so glad you have let me come to you. You are in deep waters, poor girl.’ I saw two. "Yes," he said, dismounting and motioning me to do the same. Kendall took our bridles. Leaving him with the animals we went over the fence, through the cotton, across the road at a point terribly near the lighted and guarded shop, and on down the field of corn, to and over its farthest fence; stooping, gliding, halting, crouching, in the cotton-rows and corn-rows; taking every posture two upright gentlemen would rather not take; while nevertheless I swelled with pride, to be alone at the side--or even at the heels--of one who, for all this apparent skulking and grovelling, and in despite of all the hidden drawings of his passion for a fair woman at this hour somewhere in peril, kept his straight course in lion-hearted pursuit of his duty (as he saw it) to a whole world of loves and lovers, martyrs and fighters, hosts of whom had as good a right to their heart's desire as I to mine or he to his; and I remembered Charlotte Oliver saying, on her knees, "I believe no beauty and no joy can be perfect apart from a love that loves the whole world's joy better than any separate joy of any separate soul." That Plato put forward the ethical theory of the Protagoras in perfect good faith cannot, we think, be doubted; although in other writings he has repudiated hedonism with contemptuous aversion; and it seems equally evident that this was his earliest contribution to positive thought. Of all his theories it is the simplest and most Socratic; for Socrates, in endeavouring to reclaim the foolish or vicious, often spoke as if self-interest was the paramount principle of human nature; although, had his assumption been formulated as an abstract proposition, he too might have shrunk from it with something of the uneasiness attributed to Protagoras. And from internal evidence of another description we have reason to think that the Dialogue in question is a comparatively juvenile production, remembering always that the period of youth was much more189 protracted among the Greeks than among ourselves. One almost seems to recognise the hand of a boy just out of college, who delights in drawing caricatures of his teachers; and who, while he looks down on classical scholarship in comparison with more living and practical topics, is not sorry to show that he can discuss a difficult passage from Simonides better than the professors themselves. Nor is this all. After sharply distinguishing what is from what is not, and refusing to admit any intermediary between them, Aristotle proceeds to discover such an intermediary in the shape of what he calls Accidental Predication.236 An accident is an attribute not necessarily or usually inhering in its subject—in other words, a co-existence not dependent on causation. Aristotle could never distinguish between the two notions of cause and kind, nor yet between interferences with the action of some particular cause and exceptions to the law of causation in general; and so he could not frame an intelligible theory of chance. Some propositions, he tells us, are necessarily true, others are only generally true; and it is the exceptions to the latter which constitute accident; as, for instance, when a cold day happens to come in the middle341 of summer. So also a man is necessarily an animal, but only exceptionally white. Such distinctions are not uninteresting, for they prove with what difficulties the idea of invariable sequence had to contend before even the highest intellects could grasp it. There was a constant liability to confound the order of succession with the order of co-existence, the order of our sensations with the order of objective existence, and the subjection of human actions to any fixed order, with the impossibility of deliberation and choice. The earlier Greek thinkers had proclaimed that all things existed by necessity; but with their purely geometrical or historical point of view, they entirely ignored the more complex questions raised by theories about classification, logical attribution, and moral responsibility. And the modifications introduced by Epicurus, into the old physics, show us how unanswerable Aristotle’s reasonings seemed to some of his ablest successors. only three dances with me. He said he was bashful about dancing Please get well--fast--fast--fast. I want to have you close So it was in Larry’s race, with Dick, Sandy and the caretaker. "I'm goin' to stop him killin' mules," he said to himself. "I rayly hope I won't kill him, but that's a secondary matter. Providence'll settle that. It's my duty to stop him. That's clear. If his time's come Providence'll put the bullet where it'll kill him. If it ain't, it won't. That's all. Providence indicates my duty to me. The responsibility for the rest is with Providence, who doeth all things well." ile look 4 it EvEry dAy til i git it. Awake, oh, for shame, ye electors of Rye! He had flung off his coat, and squared up to Realf, who, seeing no alternative, began to strip. "My lord," said Richard, "we are resolved to meet these bold men, and hear what they have to say. Shall you attend us, my lord of Canterbury?" HoME sewangdaquan ENTER NUMBET 0010www.autosemi.org.cn
