ASTM F874-98 微波感受器温度测量及外形图绘制的方法

1.1 This is a test method for measuring surface temperatures attained by microwave interactive packaging and cooking aids (that is, susceptors). It is useful for measuring susceptor/food interface temperatures during microwave preparation of foods with susceptor-based packaging, heating pads, and crisping sleeves, etc. It may also be used to measure the temperature of a susceptor exposed to extractives testing or in a liquid extraction cell to be used for nonvolatile extractives testing. The latter procedures are performed to establish test conditions for conducting extraction and migration studies using temperature versus time profiles approximating those for actual microwave preparation of the product. 1.1.1 Several of the steps of this test method are taken directly from Test Method F1308 which gives extraction testing procedures for susceptors. 1.2 This standard does not purport to address all of the safety problems, 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.

ANSI/ASTM A343:1997 电源频率下用瓦特计-安培计-伏特计法和25厘米艾普斯亭(EPSTEIN)机架测定材料交流电磁性能的方法

This test method covers tests for the magnetic properties of basic flat-rolled magnetic materials at power frequencies (25 to 400 Hz) using a 25-cm Epstein test frame and the 25-cm double-lap-jointed core. It covers the determination of core loss, rms exciting power, rms and peak exciting current, and several types of ac permeability and related properties of flat-rolled magnetic materials under ac magnetization.This test method shall be used in conjunction with Practice A34.This test method provides a test for core loss and exciting current at moderate and high inductions up to 15 kG (1.5T) on nonoriented electrical steels and up to 18 kG (1.8T) on grain-oriented electrical steels. The frequency range of this test method is normally that of the commercial power frequencies 50 to 60 Hz. With proper instrumentation it is also acceptable for measurements at other frequencies from 25 to 400 Hz.This test method also provides procedures for calculating ac impedance permeability from measured values of rms exciting current and for ac peak permeability from measured peak values of total exciting currents at magnetizing forces up to about 150 Oe (12 000 A/m).Explanation of symbols and abbreviated definitions appear in the text of this test method. The official symbols and definitions are listed in Terminology A340.The values stated in either customary (cgs-emu and inch-pound) units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets except for the sections concerning calculations where there are separate sections for the respective unit systems. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the systems may result in nonconformance with this test method. 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.
