Flasks may be marked with an identification number (serial number) at the option of the manufacturer. 1.1.2 Class B8212;General purpose flasks are of the same basic design as Class A flasks. However, volumetric tolerances for Class B flasks shall be within twice the specified range allowed for Class A flasks. These flasks need not be marked with their class designation. Note 18212;Specifications for micro volumetric flasks in sizes from 1 mL to 25 mL, inclusive, are given in Specification E237.

ASTM E563-08 作为参考温度制备和使用的冰点浴的标准实施规程

This practice is adequate for use with other ASTM standards that specify the ice point as a reference. It is also intended to be adequate for most other ice-point reference purposes. The ice point is a common practical industrial reference point of thermometry. The ice point is relatively simple to realize and provides a readily available natural fixed-point reference temperature. Use in Resistance Thermometry: The ice point was a defining fixed point on practical temperature scales prior to 1960. The ITS-90 defines W(T90) = R(T90)/R(273.16 K), the measured resistance ratio of a Standard Platinum Resistance Thermometer (SPRT), in reference to the water triple point, not the ice point (1). In many instances, where the water triple point is not available, or when the accuracy obtainable with the water triple point is not required, reference to a properly established and maintained ice-point reference is used. For industrial-quality resistance thermometers, the resistance value is determined for 0 °C, and an uncertainty that is appropriate for the quality of the ice-point realization is assigned. Use in Thermoelectric Thermometry: In thermoelectric thermometry, the ice point is ordinarily used as the reference temperature (2). Adequate thermoelectric reference requires that thermocouple junctions be well-coupled thermally to the bath, electrically isolated from each other and from the bath, and adequately immersed to avoid perturbing the reference-junction temperatures by radiation and longitudinal conduction of heat along the thermoelements (3 and 4). Use in Liquid-in-Glass Thermometry: In liquid-in-glass thermometry, the ice point is ordinarily used as the reference temperature (6). The periodic recalibration of a liquid-in-glass thermometer at the ice point provides a reliable indication of the effect of gradual relaxation of residual mechanical strains in the glass that have a significant effect on the volume of the bulb (6).1.1 This practice covers a method of preparing, maintaining, and using a temperature reference bath of a mixture of shaved ice and water, saturated with air at a pressure of 101 325 Pa (1 atm). 1.2 An industrial practice for relating values referenced to the ice point and to the water triple point on the ITS-90 is included. 1.3 Methods to promote uniformity of bath temperature by mechanical stirring or agitation are not described in detail. 1.4 Methods of approximating the ice point, as by thermostatically-controlled refrigeration, are not covered by this practice. 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.

ASTM F1275-03e1 筛子性能的标准试验方法

The energy input rate test is used to confirm that the griddle is operating properly prior to further testing. The temperature uniformity of the cooking surface is used by food service operators to choose a griddle that provides a uniformly cooked product. Preheat energy and time can be useful to food service operators to manage power demands and to know how rapidly the griddle can be ready for operation. Idle energy rate and pilot energy rate can be used to estimate energy consumption during noncooking periods. Cooking energy efficiency is a precise indicator of griddle energy performance under various loading conditions. This information enables the food service operator to consider energy performance when selecting a griddle. Production capacity is used by food service operators to choose a griddle that matches their food output requirements.1.1 This test method evaluates the energy consumption and cooking performance of griddles. The food service operator can use this evaluation to select a griddle and understand its energy efficiency and production capacity.1.2 This test method is applicable to thermostatically controlled, single-source (bottom) gas and electric griddles.1.3 The griddle can be evaluated with respect to the following (where applicable):1.3.1 Energy input rate (10.2,1.3.2 Temperature uniformity across the cooking surface and accuracy of the thermostats (10.3),1.3.3 Preheat energy and time (10.4),1.3.4 Idle energy rate (10.5),1.3.5 Pilot energy rate (10.6),1.3.6 Cooking energy rate and efficiency (10.7), and1.3.7 Production capacity and cooking surface temperature recovery time (10.7).1.4 The values stated in inch-pound units are to be regarded as the standard.
