Sampling10.1 Arepresentative production model shall be selected forperformance testing.10.2 Unless otherwise specified in the contract or purchaseorder, samples selected for testing and inspection by attributesshall be determined in accordance with ANSI Z1.4.11.

40、 Test Methods11.1 This test method measures the ability of a freezer tocontinuously produce frozen product at a given rate. If aproduction rate is not stated by the manufacturer, the freezershould meet the minimum rate of the appropriate ASTM size(see 4.3).11.2 Test Preparation:11.2.1 Ambient air te

41、mperature should be 75 to 80F (24 to27C) for air-cooled freezers. Inlet cooling water shall be 80F(27C) minimum for water-cooled freezers.11.2.2 Test mix formulations shall contain 32 to 37 % solidsfor softserve and 24 to 28 % solids for shake. Mix temperatureshould be 40 to 42F (4 to 6C) when put i

42、nto the freezer.11.2.3 Finished product parameters for the capacity testshall be within this range:Softserve 18 to 20F (8 to 7C) 50 % max overrunShake, without syrup 26 to 29F (3 to 2C) 60 % max overrun11.2.4 The freezer shall be set up in accordance with themanufacturers instructions. Start the ini

43、tial freeze down andallow the unit to cycle off. Draw approximately one pint ofproduct to start a refrigeration cycle. Begin the capacity testwhen the freezer cycles off.11.2.5 Draw product into an 8-oz (237-mL) container forSize 1 and 5 freezers. For all other freezers use a 16-oz(473-mL) container

44、. Determine the draw rate by dividing 225by the manufacturers rating (finished volume gallons per hour(litres per hour) when drawing an 8-oz (237-mL) sample.Divide 450 by the manufacturers rating (finished volumegallons per hour (litres per hour) when drawing a 16-oz(473-mL) sample. See Table 1 for

45、typical rating samples.11.2.6 Record finished product temperature and overrunpercentage in accordance with Table 2.11.2.7 The capacity test shall be conducted for one hour.Additional mix at 40 to 42F (4 to 6C) may be added to themix reservoir during the test.11.3 Precision and Bias:11.3.1 No stateme

46、nt is made about either the precision orbias of the test method in 11.2.5for measuring the gallons perhour (litres per hour) capacity since the result merely stateswhether there is conformance to the criteria for successspecified in the procedure.12. Inspection12.1 Inspection of the material shall b
