خلاصة
The test method covers standard procedures for measuring and analyzing surface temperatures through microwave interactive packaging and cooking AIDS (أي. pedestals). This program can be used to measure the temperature of the base/food interface during microwave-handling of food in base based packages, heating pads and crisp sleeves, إلخ. It can also be used to expose a temperature profile of a base in a vial for testing volatile extracts, or in a liquid (PTFE-fluorocarbon polymer) extraction tank for testing non-volatile extracts. The latter step is carried out to establish the test conditions for the extraction and migration of temperature and time curves that approximate the temperature curves of the actual microwave preparation of the product.

ASTM F874-2019 Standard Test Method for Temperature Measurement and Profile Analysis of Microwave Receptors

خطوة 1: نِطَاق
1.1 This is a test method for measuring surface temperature, which is achieved by microwave interactive packaging and cooking AIDS (أي. receptors). It is used to measure the temperature of the receptor/food interface during microwave preparation of food using sensory-based packaging, heating pads and crispy sleeves, إلخ. It can also be used to measure the temperature of receptors exposed to extraction tests or liquids used in extraction pools for non-volatile extraction tests. The latter step is carried out to establish the test conditions for the extraction and migration of temperature and time curves that approximate the temperature curves of the actual microwave preparation of the product.

1.1.1 Several steps of this test method are taken directly from test method F1308, which provides an extraction test procedure for the base.

1.2 تعتبر القيم المعبر عنها بوحدات النظام الدولي (SI) بمثابة قيم قياسية. ولا يشمل هذا المعيار وحدات القياس الأخرى.

1.3 لا يهدف هذا المعيار إلى معالجة كافة المخاوف المتعلقة بالسلامة المرتبطة باستخدامه. تقع على عاتق مستخدمي هذه المواصفة القياسية مسؤولية تحديد السلامة المناسبة, المواصفات الصحية والبيئية وتحديد مدى تطبيق القيود التنظيمية قبل الاستخدام.

1.4 يعتمد هذا المعيار الدولي على مبادئ التقييس المعترف بها دوليًا المنصوص عليها في القرار المتعلق بمبادئ تطوير المعايير الدولية, المبادئ التوجيهية والتوصيات الصادرة عن منظمة التجارة العالمية بشأن العوائق الفنية أمام التجارة (TBT) لجنة.
