The shear rate of a Newtonian fluid is directly proport
5、ional to the shear stress. A Newtonian fluid will begin to move immedi- ately upon application of a stress; it has no yield stress which must be achieved before flow begins. 3.2 lot: All compound produced in a single pro- duction run from the same batches of raw materials under the same fixed condit
6、ions and presented for vendor s inspection at one time. NOTE 1 The compound may be packaged in smaller quantities under the basic lot approval provided lot identifi- cation is maintained. 3.3 preproduction test: Test to determine con- formance to all technical requirements of this Inter- national St
7、andard. 3.4 acceptance test: Test performed to determine conformance to the requirements given in 4.2.6, 4.2.7 and 4.2.10. 3.5 periodic test: Test to determine conformance to the requirements given in 4.2.8.2 and 4.5. 4 Performance requirements 4.1 Composition The fluid shall contain a freezing-poin
8、t depressant. The composition of the fluid shall otherwise be at the manufacturer s discretion. The fluid may contain ad- ditives, provided the requirements of this International Standard are met.
