5.1 This test method is intended to measure volatile extractables that may be emitted from a microwave susceptor material during use. It may be a useful procedure to assist in minimizing the amount of volatile extractables either through susceptor design or manufacturing processes.5.2 Modification of this procedure by utilizing appropriate qualitative GC detection such as a mass spectrometer in place of the flame ionization detector may provide identification of volatile extractables of unknown identity.1.1 This test method covers complete microwave susceptors.1.2 This test method covers a procedure for quantitating volatile compounds whose identity has been established and which are evolved when a microwave susceptor sample is tested under simulated use conditions.1.3 This test method was collaboratively evaluated with a variety of volatile compounds (see statistical evaluation). For compounds other than those evaluated, the analyst should determine the sensitivity and reproducibility of the method by carrying out appropriate spike and recovery studies. The analyst is referred to Practice E260 for guidance.1.4 For purposes of verifying the identity of or identifying unknown volatile compounds, the analyst is encouraged to incorporate techniques such as gas chromatography/mass spectroscopy, gas chromatography/infrared spectroscopy, or other techniques in conjunction with this test method.1.5 A sensitivity level of approximately 0.025 μg/in.2 is achievable for the compounds studied in Table 1. Where other compounds are being quantitated and uncertainty exists over method sensitivity, the analyst is referred to Practice E260 for procedures on determining sensitivity of chromatographic methods.1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 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. Specific safety hazards warnings are given in 10.2, 11.1, and 11.6.1.8 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.

5.1 This test method is for evaluating ceramic products that are intended for reheating in a Consumer based microwave oven. It is not intended for evaluating products that will be used in commercial type microwaves.5.2 This test method is not intended to evaluate metallic or polymeric based products.5.3 Ceramic products intended for microwave use must also be evaluated for thermal shock resistance and pass the 325 °F criteria as described in Test Method C554, before being tested for microwave safety. This would include specific tests for dinnerware, cookware, drinkware and ancillary items intended for use with hot foods, such as gravy boats or any product intended for microwave use.5.4 Dishes having a metallic glaze, decoration or paint should not be used in this test or microwave ovens unless it is specifically designed for and marked as microwave safe.1.1 This test method determines the suitability of ceramicware for use in microwave re-heating applications. Microwave ovens are mainly used for reheating and defrosting frozen foods. Severe thermal conditions can occur while reheating foods. Typical reheating of foods requires one to 5 min in the microwave at the highest power settings. Longer periods than 5 min are considered cooking. Cooking test methods and standards are not addressed in this test method. Most ceramicware is minimally absorbing of the microwave energy and will not heat up significantly. Unfortunately there are some products that absorb microwave energy to a greater extent and can become very hot in the microwave and pose a serious hazard. Additionally, the nature of microwave heating introduces radiation in a non-uniform manner producing temperature differentials in the food being cooked as well as the ceramic container holding it. The differential may become great enough to thermal shock the ware and create dangerous conditions.1.2 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.1.3 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.

5.1 This practice provides a means of preparing a number of gel vehicle samples with minimum use of materials and time. It provides a means of quickly characterizing and comparing the gelability or reactivity of resins, vehicles, and gelling agents.1.1 This practice outlines a procedure for preparing gelled vehicle samples using a microwave oven.1.2 The test samples can be used for characterizing the gelability or reactivity of resins, gelling agents, and vehicles used in the manufacture of oil based printing inks, or both.1.3 Evaluation of the gelled vehicles may, depending upon preference, be either visual or instrumental.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 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.
