5.1 Refer to Guides E720 and E844 for the selection, irradiation, and quality control of neutron dosimeters. 5.2 Refer to Practice E261 for a general discussion of the determination of fast-neutron fluence and fluence rate with threshold detectors. 5.3 The activation reaction produces 32P, which decays by the emission of a single beta particle in 100 % of the decays, and which emits no gamma rays. The half life of 32P is 14.284 (36)3 days (1) 4 and the maximum beta energy is 1710.66 (21) keV (1). 5.4 Elemental sulfur is readily available in pure form and any trace contaminants present do not produce significant amounts of radioactivity. Natural sulfur, however, is composed of 32S (94.99 % (26)), 34S (4.25 % (24)) (2), and trace amounts of other sulfur isotopes. The presence of these other isotopes leads to several competing reactions that can interfere with the counting of the 1710-keV beta particle. This interference can usually be eliminated by the use of appropriate techniques, as discussed in Section 8. 1.1 This test method describes procedures for measuring reaction rates and fast-neutron fluences by the activation reaction 32S(n,p)32P. 1.2 This activation reaction is useful for measuring neutrons with energies above approximately 3 MeV. 1.3 With suitable techniques, fission-neutron fluences from about 5 × 108 to 1016 n/cm 2 can be measured. 1.4 Detailed procedures for other fast-neutron detectors are described in Practice E261. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 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 use of the body measurement information in Table 1 and Table 2 will assist manufacturers in developing patterns and garments that are consistent with the current anthropometric characteristics of the population of interest. This practice should, in turn, reduce or minimize consumer confusion and dissatisfaction related to apparel sizing (also refer to ISO 3635 Size Designation Procedures).4.2 Three-dimensional avatars depicting each of the young men sizes were created by Alvanon, Inc. and included in this standard to assist manufacturers in visualizing the posture, shape, and proportions generated by the measurements charts in Table 1 and Table 2. (See Figs. 1-6.)FIG. 1 Form Front View 32-38FIG. 2 Form Front View 39-48FIG. 3 Form Side View 32-38FIG. 4 Form Side View 39-48FIG. 5 Form Back View 32-38FIG. 6 Form Back View 39-481.1 These tables list body measurements of young men figure type sizes 32-48. Although these are body measurements, they can be used as a baseline in designing apparel for young men in this size range when considering such factors as fabric type, ease for body movement, styling, and fit.1.2 These tables list body measurements for the complete range of young men sizing.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.4 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.1.5 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.

This specification covers jacketed kettles using steam as a source of heat for cooking food in commercial and institutional food service establishments. However, it does not cover equipment used by food processors. Covered by this specification are jacketed kettles of various sizes (capacities), grades (Grades 1-3 based on maximum working pressure), styles (Styles 1-5 according to mounting configuration), and classes (Classes A-D based on steam source, whether direct steam or gas-fired or electric steam generator). Kettle and steam jacket shall be manufactured from Type 304, 304L, 316, or 316L corrosion resistant steel. All exterior surfaces of Styles 3-5 kettle stands and bases shall be made of Type 302, 304, 316, or 430 corrosion resistant steel, while those of the kettle mount or support base shall be chrome plated or made of Type 304, 316, or 430 corrosion resistant steel such as for exterior surfaces of console and base of Class B and C kettles. As specified, the kettles shall be provided with the following components: insulation casing, covers and/or operating handles, safety relief valve, swing spout water supply, basket insert, tilt mechanism (hand or crank tilt), kettle mount or support base, control box, safety cut-off, and thermostat. The kettle shall be tested for capacity, heating time, and energy utilization, and shall conform to the requirements specified.1.1 This specification covers jacketed kettles that use steam as a heat source for cooking food in commercial and institutional food service establishments. This specification does not cover equipment used by food processors who normally package the food that they cook.1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.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.
