Appendix A
(normative sex appendix)
The actual inject quality of the machine that note model, open the time that shut a model, open those who close modular career to detect method

Of quality of A.1 actual inject detect
A.1.1 detects condition
A) stock is recommended use polystyrene (PS)
B) nozzle part heats temperature is 216 ℃ ± 6 ℃
C) inject when model beforehand nozzle is in the condition that shut a model;
D) rated inject journey
A.1.2 detects method
Undertake is opposite injecting for nothing, after waiting for stock to cool, with the standard weighing apparatus weighs out its quality, detect 3 times, take 3 times finally detect the arithmetical average of the result, regard actual inject quality as the value.
A.2 opens the time that shut a model
A.2.1 detects condition
A) do not go up the mould initiates the action that shut a model
B) open the journey that shut a model to press watch A.1 regulation

Add up to modular force KN ≤ 250 250 ~ of > 400 400 ~ of > 630 630 ~ of > 1000 1000 ~ of > 1250 1250 ~ of > 1600 1600 ~ of > 2000 2000 ~ of > 2500
Start the journey that shut a model 200 220 240 270 300 350 400 450
A.2.2 detects method
Use stopwatch or other more accurate time device is made not less than 5 detect (measure 10 to open the journey that shut a model to circulate every time, calculate arithmetical average, as every time gradational result) , next take out detects 5 times the maximum in the result and the least value, take 3 times next detect the arithmetical average of the result, as open value of the time that shut a model. A.3 starts the career that shut a model A.3.1 detects conditionA) do not go up the mould initiates the action that shut a modelB) the regulation that opens the journey that shut a model to be expressed by A.2
