ITU-T Y.2803-2007使用传统公用交换电话网(PSTN)或综合业务数字网(ISDN),作为移动网络用户接入固定网络的调频C业务.19号研究组

In a fixed-mobile convergence (FMC) network environment, convergence between legacy PSTN and ISDN and mobile networks is a typical example of a pre-IMS FMC network environment. ITU-T Recommendation Q.1763/Y.2803 defines the service features, service architecture, and capability requirements of the convergence service between legacy PSTN and ISDN and mobile networks. An example of the implementation of the converged service is provided.

ASTM A803/A803M-2003焊接铁素体不锈钢给水加热器管的标准规范

1.1 This specification covers welded ferritic stainless steel feedwater heater tubes including those bent, if specified, into the form of U-tubes for application in tubular feedwater heaters. 1.2 The tubing sizes covered shall be 5/8 to 1 in. [15.9 to 25.4 mm] inclusive, in outside diameter, and average or minimum wall thicknesses of 0.028 in. [0.7 mm] and heavier. 1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.

ASTM D8032-2016采用颜色指示剂滴定法测定对苯二甲酸酸值的标准试验方法

5.1x00a0;An estimate of TA purity can be determined by titrating with KOH. As an index of TA purity, the acid number can be used as a guide in the quality control of TA production. 1.1x00a0;This test method covers the determination of acid number of terephthalic acid (TA) by color-indicator titration. Acid number of TA product is usually within 674 to 676 mg KOH/g. 1.2x00a0;In determining the conformance of the test results using this method, results shall be rounded off in accordance with the rounding-off method of Practice E29. 1.3x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4x00a0;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 D8032-2020用颜色指示剂滴定法测定对苯二甲酸酸值的标准试验方法

1.1 This test method covers the determination of acid number of terephthalic acid (TA) by color-indicator titration. Acid number of TA product is usually within 674 to 676 mg KOH/g. 1.2 In determining the conformance of the test results using this method, results shall be rounded off in accordance with the rounding-off method of Practice E29. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D8034/D8034M-2016非水发动机冷却剂模拟服务腐蚀试验的标准试验方法

4.1x00a0;This test method, by a closer approach to engine cooling system conditions, provides better evaluation and selective screening of engine coolants than is possible from glassware testing (Test Method D7935/D7935M). The improvement is achieved by controlled circulation of the coolant, by the use of automotive cooling system components, and by a greater ratio of metal surface area to coolant volume. 4.2x00a0;Although this test method provides improved discrimination, it cannot conclusively predict satisfactory corrosion inhibition and service life. If greater assurance of satisfactory performance is desired, it should be obtained from full-scale engine tests and from field testing in actual service. 4.3x00a0;Significance and interpretation of the test and its limitations are discussed further in Appendix X1. 4.4x00a0;The substitution of components in the apparatus of Section 5 is permissible if agreed upon by the contracting parties. 1.1x00a0;This test method evaluates the effect of a circulating engine coolant on metal test specimens and automotive cooling system components under controlled, essentially isothermal laboratory conditions. 1.2x00a0;This test method specifies test material, cooling system components, type of coolant, and coolant flow conditions that are considered typical of current automotive use. 1.3x00a0;The values stated in either SI units or inch-pound 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. Some values have only SI units because the inch-pound equivalents are not used in practice. 1.4x00a0;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. Specific precautionary statements are given in Section 6.
