5.1 This standard is intended to provide guidance on the deployment of blast resistant trash receptacles that focuses on the mitigation of human injury. It is not in general intended to provide guidance on the protection of structures in the vicinity of where the blast resistant trash receptacles are deployed.5.2 The importance of a strategy and procedures for the deployment of blast resistant trash receptacles in crowded places cannot be overly emphasized. Trash receptacles in crowded places have been, and continue to be, an attractive repository for explosives. The selection of deployment locations impacts both the mitigation of the effects of an explosion occurring within one as well as the convenience of using the receptacles.5.3 Two major effects resulting from an explosion in a trash receptacle are the production of primary and secondary fragments as well as overpressure from the detonation. The recommendations in this guide are intended to mitigate the damaging effects of fragmentation and overpressure in crowded places.5.4 Another effect resulting from an explosion in a trash receptacle is the fireball. This effect may cause burns to people caught within or near to the fireball. Also, it is possible that the heat output from an explosion may cause nearby combustible material to ignite. It is important, therefore, that blast resistant trash receptacles are not placed near combustible materials.5.5 The deployment of blast resistant trash receptacles provides a means for decreasing injury and lethality during an explosive event no matter their location when compared to the protection afforded by ordinary trash receptacles or clear plastic bags. Fragments resulting from explosions create the greatest danger to people as fragments may travel several hundred meters and still have velocities that could be lethal or injurious. Blast resistant trash receptacles that meet the requirements of Specification E2740 when subjected to internal explosions equal to or less than the force protection rating contain horizontal primary fragments and do not produce secondary fragments.5.6 This guide provides general provisions for the deployment of blast resistant trash receptacles. Every facility or venue has unique features associated with factors such as demographics, location, and functions. Operational and explosive effects considerations (see  Section 7) provide basic recommendations that may be sufficient for many facilities buildings and venues, but may not be specifically applicable to others. For example, special security concerns at high value facilities or high pedestrian count venues will require guidance concerning the deployment of blast resistant trash receptacles from security personnel familiar with that facility.5.7 The guide is intended for use by individuals in both the private and public sectors who are considering the purchase and deployment of blast resistance trash receptacles.1.1 This guide identifies the key factors that should be considered prior to the deployment of blast resistant trash receptacles (BRTRs) in crowded places.1.1.1 Guidance is included for their deployment at interior and exterior locations associated with the crowded places.1.2 Facilities and venues where blast resistant trash receptacles may be deployed include, but are not limited to:1.2.1 Airports,1.2.2 Banks and other financial institutions,1.2.3 Bars and nightclubs,1.2.4 Convention centers,1.2.5 Entertainment and event centers,1.2.6 Hotels,1.2.7 Health care locations,1.2.8 Museums,1.2.9 Places of worship,1.2.10 Public government locations including fire and police stations,1.2.11 Railway stations, bus stations, and related transit areas,1.2.12 Restaurants,1.2.13 Retail centers and malls,1.2.14 Schools, universities, and related areas used for education,1.2.15 Stadiums and arenas, and1.2.16 Theaters.1.3 Guidance on conducting a threat assessment or vulnerability analysis, and on responding to incidents associated with the deployment of blast resistant trash receptacles is beyond the scope of this document.1.4 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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, 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.

5.1 The height of surface profile has been shown to be a factor in the performance of various coatings applied to steel. For this reason, surface profile should be measured prior to coating application to ensure conformance of a prepared surface to profile requirements specified by the manufacturer of a protective coating or the coating job specification.NOTE 2: The peak count/peak density has been shown to be a factor in the performance of various coatings applied to steel. According to research performed by Roper, Weaver and Brandon6, an increase in peak count can improve the adhesion of some coatings to the prepared steel, as well as provide greater resistance to corrosion undercutting once the coating becomes damaged in service.NOTE 3: Optical microscope methods serve as a referee method for surface profile measurement methods A and B. Profile depth designations are based on the concept of mean maximum profile (h max); this value is determined by averaging a given number (usually 20) of the highest peak to lowest valley measurements made in the field of view of a standard measuring microscope. This is done because of evidence that coating performance in any one small area is primarily influenced by the highest surface features in that area and not by the average roughness.71.1 These test methods cover the description of techniques for measuring the profile of abrasive blast cleaned surfaces in the field, shop, and laboratory. There are other techniques suitable for laboratory use not covered by these test methods.1.2 Method B may also be appropriate to the measurement of profile produced by using power tools.NOTE 1: The Method B procedure in this standard was developed for use on flat surfaces. Depending on the radius of the surface, the results could have greater variability with lower values and averages.1.3 SSPC standard SSPC-PA 17 provides additional guidance for determining conformance with surface profile requirements.1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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 Abrasive media may contain ionic contamination naturally (for example, beach sand), from manufacturing (quenching with contaminated water), transportation, storage or use (in the case of abrasive that is reused). Ionic contamination on the abrasive may transfer to the surface during abrasive blast cleaning, resulting in potential osmotic blistering, accelerated underfilm corrosion and premature coating failure.4.2 This test method describes a shop/field procedure for assessing the level of conductive species on an abrasive.4.3 Abrasive standards published by SSPC (AB) and ISO 11126 provide tolerance levels for water soluble contaminants of the abrasive.1.1 This test method describes a procedure for assessing blast cleaning abrasives for the presence of conductive-potential, ionic contaminants by determining the total concentration of water soluble conductive species using a conductivity test.1.2 This test method does not identify the ionic species present nor provide quantitative results on each species.1.3 This test method is based on a volume comparison among abrasives of similar sizes. A volume comparison is more closely related to surface area of the abrasives than is a weight comparison.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, 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.

5.1 Blast resistant doors are designed to protect against the problems and dangers created by a planned or accidental explosion or pressure leak. This test method will provide reasonable assurance to the specifier of the reliability of a door's structure, the restraining hardware, the frame, and the frame anchors when used in a blast resistant application.1.1 This test method covers the structural performance of metal doors and frames and their restraining hardware (such as latches and hinges) used as a blast resistant barrier. This method involves applying an equivalent static pressure based on the characteristics of the specified blast pressure and structural properties of the door panel design.1.2 The static tests are valid for the unit size tested or for smaller units of analogous construction. Extrapolation of test results for units larger than the test specimen are not permitted.1.3 This standard test method is not applicable to tests where the forces are created by explosive charges, forced air from a shock tube apparatus, or any other method used to generate a dynamic load.1.4 The proper use of this method requires knowledge of the principles of pressure, deflection, and when applicable, strain gauge measurement.1.5 Using this method, specimens may be tested to determine ultimate static capacity or tested to specific static test loads.1.5.1 Procedure A  shall be used when a load-deflection curve is not required and a single load is applied.1.5.2 Procedure B  shall be used when a load-deflection curve is required and a single or multiple loads are applied.1.6 The values stated in SI units are to be regarded as the standard. The values provided in parentheses are for information only.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.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 practice provides a design load suitable for sizing blast resistant glazing comprised of laminated glass or insulating glass fabricated with laminated glass.5.2 Blast resistant glazing comprised of laminated glass or insulating glass fabricated with laminated glass shall be sized to resist the 3-second duration equivalent design loading from this standard practice using the procedures described in Practice E1300.5.3 In the event a blast loading does not occur to blast resistant glazing comprised of laminated glass or insulating glass fabricated with laminated glass sized using the 3-second duration loading determined herein, the blast resistant glazing will have a probability of breakage less than or equal to 8 lites per 1000 at the first occurrence of a loading equal to the 3-second duration design loading determined herein.5.4 Blast resistant glazing designed to resist the 3-second equivalent load as determined herein, when properly supported as part of a blast resistant glazing system, is designed to perform to minimal hazard as defined in Test Method F2912.1.1 This practice sets forth a method to specify an equivalent 3-second design loading suitable to use with Practice E1300 to select the thickness and type of blast resistant glazing fabricated with laminated glass to glaze a fenestration. Glass plies used to construct laminated glass are recommended to be either annealed or heat strengthened glass. This analytical method for glazing should be used with caution for glazing panels larger than 1.8 m by 2.4 m (6 ft by 8 ft) as this size panel exceeds database of testing upon which this standard is based.1.2 This practice applies to blast resistant glazing fabricated using laminated glass only, including single laminated glass and insulating glass fabricated with laminated glass. As a minimum, insulating glass shall use laminated glass for the inboard (protected side) lite.1.3 This practice assumes that blast resistant glazing shall be attached to its supporting frame using a captured bite so that it does not detach in the event of fracture due to a blast event.1.4 Blast resistant glazing designed using this practice recommends the use of annealed or heat strengthened glass plies for the laminated glass. Blast testing has shown that use of fully tempered glass plies, when fractured during a blast event, have poorer post blast performance than annealed or heat strengthened glass plies. Laminated glass fabricated with fully tempered glass plies has a tendency to leave the supporting glazing system frame after fracture whereas laminated glass fabricated with annealed or heat strengthened glass plies will remain in the frame and absorb remaining load through tensile membrane behavior. Use of the annealed or heat strengthened glass plies will also reduce the amount of load transferred into the structure.1.5 The equivalent 3-second design load as determined herein shall not apply to the design of monolithic glazing, plastic glazing, or security film applied to existing glazing configurations in an attempt to achieve blast resistance.1.6 The values stated in SI units are to be regarded as the standard. Values given in parentheses are for information only. For conversion of quantities in various systems of measurements to SI units refer to ANSI IEEE/SI 10.1.7 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.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.

This test method describes the optical emission vacuum spectrometric procedure for examining blast furnace iron (hot metal) containing 4.2 to 5.0 % carbon by the point-to-plane technique. This spectrochemical technique is intended specifically for the analysis of silicon, manganese, phosphorus, titanium, and sulfur in specified concentration ranges in blast furnace iron. Apparatus needed for this procedure shall include sample mold, grinder, supporting electrode, excitation source, spectrometer, and appropriate measuring system. The sample is excited in an inert gas atmosphere by a controlled triggered capacitor discharge using the point-to-plane technique. Using a vacuum spectrometer, the radiant energies of selected analytical lines and an internal standard line are measured by photomultipliers. The output current of each photomultiplier is accumulated and stored during the exposure period as a charge on an associated capacitor, where it appears as a measurable voltage. At the end of the exposure period the voltages corresponding to the analytical lines relative to the voltage for the internal standard line are measured. The measuring system may be calibrated in terms of percent concentration.1.1 This test method describes the spectrochemical procedure for the analysis of blast furnace iron (hot metal) containing 4.2 to 5.0 % carbon for the following elements in the indicated ranges:Elements Concentration Range, %Silicon 0.50 to 2.00Manganese 0.20 to 1.50Phosphorus 0.020 to 0.15Titanium 0.02 to 0.10Sulfur 0.010 to 0.0501.2This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 This method may be useful in assuring conformance of a prepared surface to profile requirements specified by the manufacturer of a protective coating.5.2 This method includes determination of the peak density (number of profile peaks in a specified distance). Some workers in the field believe that optimizing peak height and peak density can improve coating adhesion.5.3 This method allows specifiers to objectively define surface texture after abrasive blast cleaning rather than using subjective terms such as “angular pattern” or “dense and uniform pattern.”5.4 Because implicit and explicit definitions of “roughness” may differ substantially, numerical characterizations of profile cannot be compared directly across different methods.1.1 This test method describes a shop or field procedure for determination of roughness characteristics of surfaces prepared for painting by abrasive blasting. The procedure uses a portable skidded or non-skidded stylus profile tracing instrument. The measured characteristics are: Rt and Rpc. Additional measures of profile height (Rmax and/or Rz) may also be obtained as agreed upon by purchaser and seller. (The digitally-determined profile parameters Rt, Rmax, Ry and Rzlmax are extremely similar in definition.)1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.3 In general, this method should be limited to the measurement of surface roughness where Rt is in the range 10 to 150 μm (0.4 to 6 mil) and where the Peak Count, Rpc is less than 180 peaks/cm (450 peaks/in.).1.4 SSPC standard SSPC-PA 17 provides additional guidance for determining conformance with surface profile requirements.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.
