If the moisture level exceedsthis limit,
44、the material shall be dried for 24 h 2 h at a temperature of 105 C 5 C in vacuo or in a stream of driednitrogen.To ensure that the moisture content remains low, it is recommended that the material in the feed hopper of theinjection-moulding machine be blanketed with any suitable gas (dried air, nitr
45、ogen or argon, for example). Betterresults may be obtained using a dehumidifier hopper dryer.3.2 Injection mouldingInjection-moulded specimens shall be prepared in accordance with ISO 294-2, using the conditions specified inTable 1.Table 1 Conditions for injection moulding of test specimensMaterial
