The largest value of Error Ev in testing is regarded as the basic error of fuel dispenser according to the regulation of JJG443-98. The larger value of Repeatability of measurement En in two flow rate testing presents the repeatability of fuel dispenser. Error Ev should be 0.3%, repeatability of measurement no more than 0.15%, if beyond these scopes testing would be determined as unqualified. The contents of money indication a fuel dispenser nd money error are not regulated in the approval procedure of JJG443-98. There would exist a little error after long refueling because usually the calculation of paid money adapts the round –mode. Example of indicating valve appraisal Take an appraisal of fuel dispenser 6~60L/min for example, it is usually adapted non-presetting mode in filing station. Setting unit price as 2.75�L and preparing metal standard measurer of 100L, conduct 3 tests as maximum flow rate 60L/min and minimum flow rate 12L/min, respectively. Testing result is listed in Table 6-1. Table 6-1 Appraisal Results Article IV Important notices in appraisal Indicating value appraisal is crucial part of fuel dispenser’s testing items, which is direct foundation to determine the accuracy and qualification of fuel dispenser. The appraisal method and data processing introduced in Article III is based upon JJG443-98. Filling station should consult the above procedure and conduct self appraisal in accordance with relative requirements o fuel dispenser

mid allegations of corruption involving senior aides, a son-in-law and the president s wife. In August the president himself was questioned by prosecutors over the use of false invoices to claim money from a fund available to him for pursuing clandestine diplomacy. The KMT relishes the president s discomfort but is uncertain how to react. Even though KMT supporters have flocked to join Mr Shih, the party s chairman, Ma Ying-jeou (who is also mayor of Taipei), has been more diffident. Forcing Mr Chen to step d fuel dispenser own now would not necessarily help Mr Ma. The vice-president, Annette Lu, would then take over, and presidential polls would take place as originally scheduled in March 2008. The KMT is considering whether to mount a vote of no confidence against the DPP prime minister, Su Tseng-chang. With the KMT and its allies controlling a slim majority in parliament, this could succeed. But the KMT worries about possible in-fighting within its own ranks should this lead to a snap fuel dispenser parliamentary election. China would like the KMT to take back the presidency. But it fears that an embattled Mr Chen might try to shore up his popularity by pushing the island further towards formal independence from China. Mr Chen said last week that he was considering calling a referendum on whether to try to join the United Nations under the name Taiwan, instead of Republic of China, as the island still calls itself. This would infuriate China. Its and Mr Ma s hopes lie in the various elections that are forthcoming mayoral ones in Taipei and Kaohsiung at the end of this year, legislative polls in late 2007 and the presidential elections in 2008, when Mr Chen is constitutionally obliged to step down. The charismatic Mr Ma is a front-runner to succeed him. With Mr Chen and his party so politically damaged, it appears he has to do no more than wait.  © 2006 .  About sponsorship Kyrgyzstan A dope dupe Sep 21st 2006 | ALMATY From The Economist print edition fuel dispenser
