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 and 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 fuel dispenser 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. Th fuel dispenser e 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

s already falling and will decline rapidly unless new discoveries are made. Pemex is replacing only a fifth of the reserves it is depleting, and Mexico already imports 30% of the petrol and 23% of the natural gas it consumes. Mr Zedillo s government made a first attempt at loosening Pemex s monopoly by allowing others to import natural gas, which required a change in the constitution. But in practice Pemex is stil fuel dispenser l the sole importer. Mr Téllez, who as energy minister introduced that reform, says that the need for change is much more widely accepted now. He recommends gradual reform, starting with private investment in refining. Next, he would require Pemex to operate along more commercial lines, and then allow private investment in exploration. But the first thing that is needed is to give Pemex greater financial autonomy. The electricity industry is dominated by two state-owned monopoly distributors, the Comisión Federal de Electricidad and, in Mexico City, Luz y Fuerza. Mr Zedillo changed the constitution to allow private investment in generation; Mr Fox has secured further investment through public-private partnerships. But electricity is expensive, despite subsidies equivalent to around 1% of GDP (which benefit the rich more than the poor). Luz y Fuerza is fuel dispenser in thrall to its powerful trade union. The PAN used to be suspicious of the PRI-dominated trade unions. But Mr Fox s government has appeased the most powerful unions, such as the teachers, the employees of the Social Security Institute, the Pemex workers and the electricians. Some economists argue for constitutional amendments to reform the unions and the labour market. In practice labour in many industries is quite flexible already. A better way of taking on the over-mighty unions would be to tack fuel dispenser le the monopoly power that sustains a number of them. In view of all these economic rigidities, and of the poor quality of the judicial system, it is little wonder that Mexico does not do well in league tables of international compet
