QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The producer of the quenchant shall supply all samples for producers tests and shall be responsible for the performance of all required tests. Purchase

30、r reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the quenchant conforms to specified requirements. 4.2 Classification of Tests 4.2.1 Preproduction Tests All technical requirements are preproduction tests. 4.2.2 Acceptance Tests Water content (3.2

31、.1.1), specific gravity (3.2.1.2), and refractive index (3.2.1.3) as-received, and for viscosity (3.2.2.1) and separation temperature (3.2.2.2) of a 20% dilution are acceptance tests and shall be performed on each lot. 4.3 Requirements for Testing 4.3.1 Preproduction tests shall be conducted by the

32、producer on the quenchant to qualify the quenchant to this specification prior to the first production lot. These tests shall be performed prior to or on the initial shipment of quenchant to a purchaser, when a change in ingredients and/or processing requires reapproval as in 4.3.1.1, and when a pur

33、chaser deems confirmatory testing to be required. 4.3.1.1 New preproduction tests shall be required if the producer finds it necessary to make any change in polymer type or polymer molecular weight, in type of equipment for processing, or in manufacturing procedures. Changes in additive packages to

34、satisfy regulations (Federal, State or Local), do not require new preproduction tests, as long as the quenching characteristics are not changed, as measured by cooling curve measurements performed in accordance with ASTM D6200 and ASTM D6482 or ASTM D6549. 4.3.1.2 Testing in accordance with ASTM D62

35、00 and ASTM D6482 or ASTM D6549 shall be conducted three times, and the averaged results shall be considered identical to the control testing of preproduction material before change if the results of testing satisfy the bias and precision of ASTM D6482 or ASTM D6549. 4.3.1.3 Material qualified to pr

36、evious revisions of this specification shall not require requalification, unless purchaser deems confirmatory testing will be required. 4.4 Sampling and Testing Shall be in accordance with ASTM D4057; a lot shall be one batch or tank of quenchant offered for delivery at one time. A lot shall not exc

37、eed 10000 gallons (37854 L). 4.4.1 Test Methods 4.4.1.1 Viscosity The as-produced quenchant shall be diluted to a concentration of 20% + 0.5% by volume of quenchant, using distilled or deionized water. When diluting to 20% by volume with water, the initial water content (chemically combined with gly

38、col) shall not be considered as a part of the water of dilution. The viscosity of the diluted sample shall be determined at 104 F 1 F (40 C 0.6 C) in accordance with ASTM D445. 4.4.1.2 Separation Temperature Shall be determined by the following procedure: 4.4.1.2.1 Heat not less than a 250 mL portio

39、n of a well-mixed representative sample of diluted quenchant in a 25 150 mm Pyrex test tube. SAE INTERNATIONAL AMS3025D Page 6 of 9 4.4.1.2.2 Fit a cork stopper with a 0 to 212 F (-18 to +100 C) thermometer, so that the thermometer bulb is completely immersed in the liquid. The cork stopper should f

40、it snugly in the test tube, but should have a small V-notch on one side to vent the vapor space in the test tube. 4.4.1.2.3 Immerse the test tube in a suitable heating bath (water or clear oil) so that the liquid in the test tube is below the bath surface. Keep the test tube away from the sides and

41、bottom of the heating bath. 4.4.1.2.4 Heat the bath slowly (about 5 F (3 C) minute) with a suitable heater and closely observe the sample in the test tube. Continue heating, (but higher than 175 F (79 C) until the sample becomes hazy. 4.4.1.2.5 When the sample exhibits some haze, immediately remove

42、the test tube from the bath long enough to swirl the contents. The haze should disappear. Return the test tube to the bath and repeat this procedure until a permanent haze persists throughout the sample. Immediately observe the sample temperature. 4.4.1.2.6 Cool the sample slightly with agitation un

43、til the solution is again clear. Re-immerse in the heating bath and repeat the previous step until the haze persists again. Re-observe the sample temperature and average with the first temperature observation. 4.4.1.2.7 The two readings should differ by no more than 2 F (1 C). If the readings differ

44、 by more than 2 F (1 C), repeat the entire process with three test temperature observations until all three observations are within 2 F (1 C). 4.4.2 Cooling Rates Shall be determined by quenching the panels specified in Table 2. 4.4.2.1 For the 0.250 inch (6.35 mm) and 1.0 inch (25 mm) thick panels,

45、 an electrically insulated chromel-alumel thermocouple, not larger than 24 gauge (0.533 mm), shall be inserted in a blind hole to the mid-thickness 0.020 inch (0.51 mm) at the geometric center. The thermocouple shall be inserted in a manner that ensures intimate contact with the panel for optimum th

46、ermal transfer and shall be sealed to prevent intrusion of moisture and quenchant. Before each test, thermocouple contact with the part shall be verified with electrical resistance tests. A second thermocouple of the same size shall be positioned on the outside surface to determine the instant the s

47、pecimen enters the quenchant. Panels shall have a surface finish of 32 to 63 microinches (0.8 to 1.6 micrometers) Ra determined in accordance with ASME B46.1 and shall be chemically deoxidized prior to heating. 4.4.2.2 The 0.063 inch (1.60 mm) thick panel shall only have a thermocouple attached to t

48、he surface at the center. 4.4.2.3 The panels shall be soaked at the solution heat treating temperature specified in AMS2770 and quenched in the glycol/water solution maintained at 85 to 90 F (29 to 32 C). The glycol concentration used shall be the maximum specified in AMS2770 for the alloy/form/thic

49、kness. The tolerance on the glycol concentration shall be +0, 1%. The quench tank shall have no agitation. 4.4.2.4 The time/temperature cooling curve shall be recorded using a high speed oscillographic recorder or a computer based data acquisition system. The temperature recording instrument shall be calibrated prior to testing using a te
