? pilot-operated non-return valves;
? shuttle valves;
? dual pressure valves (AND function);
? one-way adjustable flow control valves;
? quick-exhaust valves
by testing and the methods of reporting the results of testing. General test conditions and the calculation method are provided in 香港六合彩开奖 19973鈥�1. The methods specified in 香港六合彩开奖 19973鈥�1 apply to the first failure, as obtained with the three-points moving average (3PMA) method, without repairs, but excluding outliers.
