5.1 The maximum energy input rate test is used to confirm that the steam kettle is operating within 5 % of the manufacturer's rated input so that testing may continue. This test method also may disclose any problems with the electric power supply, gas service pressure, or steam supply flow or pressure. The maximum input rate can be useful to food service operators for managing power demand.5.2 The capacity test determines the maximum volume of food product the kettle can hold and the amount of food product that will be used in subsequent tests. Food service operators can use the results of this test method to select a steam kettle, which is appropriately sized for their operation.5.3 Production capacity is used by food service operators to choose a steam kettle that matches their food output. The production capacity determined in this test method is a close indicator of how quickly the kettle can bring soups, sauces, and other liquids up to serving temperature.5.4 Heatup energy efficiency and simmer energy rate allow the operator to consider energy performance when selecting a steam kettle. Simmer energy rate is also an indicator of steam kettle energy performance when preparing foods which require long cook times, for example, potatoes, beans, rice, or stew.5.5 Pilot energy rate can be used to estimate energy consumption for gas-fired steam kettles with standing pilots during non-cooking periods.1.1 This test method evaluates the energy consumption and cooking performance of steam kettles.

1.1 The guide provides information and clarity to support the health and maintenance of Marine Sanitation Devices (MSDs) on maritime vessels and platforms to promote effective operations and performance throughout the lifecycle. This includes identification of chemicals and their derivatives that can be detrimental to proper MSD operations. This guide will promote better understanding of the impacts of certain chemicals on the health and operations of MSD systems, plus provide guidance to inform operators of best practices and procedures for effective operations and maintenance. This guide is designed to assist both operators and MSD Original Equipment Manufacturers (OEMs) in collaboratively working to ensure effective operations and maintenance, and to reduce performance degradations that result from the introduction of harmful chemicals. The primary application of this guide is to Type II MSDs (described in Section 4), installed on larger ships and employing biological treatment of sewage and gray water.NOTE 1: This guide does not constitute regulations or ship classification society rules, which should be consulted where applicable.1.2 Manufacturers preparing new product specifications or revising existing ones should follow the practices and procedures outlined herein, and be guided by the latest specifications covering similar commodities. Similarly, vessel owner/operators should consult this guide regarding in-service operations and maintenance.1.3 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.1.4 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.
4.1 The objective of this practice is to recommend appropriate biological endpoint assessments (which may or may not require testing) to establish a reasonable level of confidence concerning the biological response to a material or device, while at the same time avoiding unnecessary testing.4.2 This practice is intended to provide guidance to the materials investigator in selecting the proper procedures to be carried out for the screening of new or modified materials. Because each material and each implant situation involves its own unique circumstances, these recommendations should be modified as necessary and do not constitute the only assessment that will be required for a material. Nor should these guidelines be interpreted as minimum requirements for any particular situation. While an attempt has been made to provide recommendation for different implant circumstances, some of the recommended assessment may not be necessary or reasonable for a specific material or application.1.1 This practice recommends generic biological test methods for materials and devices according to end-use applications. While chemical testing for extractable additives and residual monomers or residues from processing aids is necessary for most implant materials, such testing is not included as part of this practice. The reader is cautioned that the area of materials biocompatibility testing is a rapidly evolving field, and improved methods are evolving rapidly, so this practice is by necessity only a guideline. A thorough knowledge of current techniques and research is critical to a complete evaluation of new materials.1.2 These test protocols are intended to apply to materials and medical devices for human application. Biological evaluation of materials and devices, and related subjects such as pyrogen testing, batch testing of production lots, and so on, are also discussed. Tests include those performed on materials, end products, and extracts. Rationale and comments on current state of the art are included for all test procedures described.1.3 The biocompatibility of materials used in single or multicomponent medical devices for human use depends to a large degree on the particular nature of the end-use application. Biological reactions that are detrimental to the success of a material in one device application may have little or no bearing on the successful use of the material for a different application. It is, therefore, not possible to specify a set of biocompatibility test methods which will be necessary and sufficient to establish biocompatibility for all materials and applications.1.4 The evaluation of tissue engineered medical products (TEMPs) may, in some cases, involve different or additional testing beyond those suggested for non-tissue-based materials and devices. Where appropriate, these differences are discussed in this practice and additional tests described.1.5 The ethical use of research animals places the obligation on the individual investigator to determine the most efficient methods for performing the necessary testing without undue use of animals. Where adequate prior data exists to substantiate certain types of safety information, these guidelines should not be interpreted to mean that testing should be unnecessarily repeated.1.6 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.
