ASTM E1603/E1603M-11 用罩式质谱探漏仪或残余气体分析仪作检漏测量的标准试验方法

Test Method A8212;This test method is the most frequently used in leak testing components. Testing of components is correlated to a standard leak, and the actual leak rate is measured. Acceptance is based on the maximum system allowable leakage. For most production needs, acceptance is based on acceptance of parts leaking less than an established leakage rate, which will ensure safe performance over the projected life of the component. Care must be exercised to ensure that large systems are calibrated with the standard leak located at a representative place on the test volume. As the volume tends to be large (>1 m3) and there are often low conductance paths involved, a check of the response time as well as system sensitivity should be made. Test Method B8212;This test method is used for testing vacuum systems either as a step in the final test of a new system or as a maintenance practice on equipment used for manufacturing, environmental test, or conditioning parts. As with Test Method A, the response time and a system sensitivity check may be required for large volumes. Test Method C8212;This test method is to be used only when there is no convenient method of connecting the LD to the outlet of the high-vacuum pump. If a helium LD is used and the high-vacuum pump is an ion pump or cryopump, leak testing is best accomplished during the roughing cycle, as these pumps leave a relatively high percentage of helium in the high-vacuum chamber. This will limit the maximum sensitivity that can be obtained.1.1 This practice covers procedures for testing the sources of gas leaking at the rate of 1 × 10−8 Pa m3/s (1 × 10−9 standard-cm3/s at 0°C) or greater. These test methods may be conducted on any object that can be evacuated and to the other side of which helium or other tracer gas may be applied. The object must be structurally capable of being evacuated to pressures of 0.1 Pa (approximately 10−3 torr). 1.2 Three test methods are described; 1.2.1 Test Method A8212;For the object under test capable of being evacuated, but having no inherent pumping capability. 1.2.2 Test Method B8212;For the object under test with integral pumping capability. 1.2.3 Test Method C8212;For the object under test as in Test Method B, in which the vacuum pumps of the object under test replace those normally used in the leak detector (LD). 1.3 Units8212;The values stated in either SI or std-cc/sec units are to be regarded separately as standard. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM F1674-11 联接PVC管用的减震装置的标准试验方法

This test method is useful for establishing any effects that a joint restraint product has on the performance of PVC pressure pipe. This test method is designed so that success in all three parts of the test provides reasonable assurance that a joint restraint product may be used on PVC pipe at the full pressure rating and capacity of the pipe. Restrained joint test specimens shall be subjected to internal pressures that are equal to the minimum burst pressure requirements for the pipe alone. The minimum burst pressure requirements for some common dimension ratios are shown in Table 1. The minimum burst pressures for other dimension ratios of pipe produced from 12454 PVC Compound (that is, pipe conforming to Specification D1785) may be determined based on a hoop stress of 6400 psi (44.13 MPa). Testing of restrained joint test specimens for 1000 h at the sustained pressure requirements indicates any tendency of the restraint to fail in the long term. The minimum sustained pressure requirements for some common dimension ratios are shown in Table 2. The minimum sustained pressure for other dimension ratios of pipe produced from 12454 PVC Compound (for example, pipe conforming to Specification D1785) may be determined based on a hoop stress of 4200 psi (28.96 MPa). A cyclic surge pressure test of restrained joint test specimens determines the effect of the joint restraint product on the cyclic fatigue life of PVC pipe. This test method provides a means for quickly identifying any reduction in performance that might result from the combination of the joint restraint product and the pipe. The peak hoop stress shall be determined for the pipe based on the Vinson equation for a period of 1 000 000 cycles. The base pressure shall be one half of the peak pressure. The peak pressure requirements for some common dimension ratios are shown in Table 3. The peak pressure for other dimension ratios for pipe produced from 12454 PVC Compound (for example, pipe conforming to Specification D1785) may be determined based on a hoop stress of 1587 psi (10.94 MPa). 1.1 This test method describes a procedure for qualifying the performance of joint restraint products for use on PVC pressure pipe systems by evaluating the effect of the joint restraint product on the performance characteristics of PVC pipe during cyclic pressure tests and static pressure tests. The PVC pipe property values referenced in this test method are for the 12454 compound as described in Specification D1784 and a 4,000 HDB shall be obtained by categorizing the LTHS in accordance with Table 1 in Test Method D2837. That includes, but is not limited to, pipe produced in accordance with the following standards: Specifications D1785 and D2241, AWWA C900 , and AWWA C905. 1.2 This test method determines the short-term performance of a joint restraint product on PVC pipe, which involves the testing of restrained joint test sections to the minimum burst pressure requirements of the pipe to determine quick burst performance. 1.3 This test method determines the long-term effect of a joint restraint product on PVC pipe, which involves the testing of restrained joint test sections to the sustained pressure requirements of the pipe for a period of 1000 h. 1.4 This test......
