SIGNIFICANCE AND USE
4.1 This classification is intended to encourage uniformity in reporting properties of MLS and Metal Layer gaskets, to provide a common language for communications between producers and users, and to guide engineers and designers in the application and construction of commercially available gaskets. (A) This classification may also be used to classify Single Layer Steel (SLS) Gaskets.(B) Refer to Specification A666 or Specification A109/A109M for Stainless Steel and Low Carbon Steel, respectively. Other metals not referenced in the table or not covered by Specification A666 or Specification A109/A109M must be defined by the producer/user (that is, H – High Temperature Alloy).(C) Refer to Practice D1418 for general information regarding rubber coating types and use Classification D2000 to define the physical properties of the rubber. This physical property information is typically specified on the gasket drawing or the customer specification, or both.(D) Coated side as specified on part drawing.  
4.2 Suffix Table 2 is provided to allow hardness designation for Active, Inactive, or Load Stoppers.  
4.2.1 If suffixes are not to be used, only the basic callout from Table 1 is required. If a suffix is used for 1 layer, it must be specified for all layers, even if a “0” is used. It cannot be assumed that hardnesses of like layers are the same; if used, all layers must be specified separately. The first layer specified must be indicated on the part drawing. To use a hardness call-out, at the end of the base callout leave a space followed by the “HR” suffix with a series of suffix numbers to specify the hardnesses for each layer.
4.2.1.1 Example: ASTM F2325, A32ANBW11 HR252—Example from Table 1 modified to add hardness requirement for the three metal layers. Active layers 1 and 3 are designated to be the same, 1/4 hard steel. Stopper layer 2 is designated to be full hard steel.
SCOPE

Standard Practices for Securement of Cargo in Intermodal and Unimodal Surface Transport

SIGNIFICANCE AND USE
4.1 Numerous sources provide detailed information as to the loading, blocking, bracing, and unloading of specific types of cargo in unimodal and intermodal transport. Some of these sources are proprietary, others are massive and complex in scope, and none are consistently promulgated to shippers, carriers, and consignees. Many of the losses experienced by cargo in transport are due to the failure to practice proper basic cargo handling and loading techniques. These practices are intended to outline those techniques in simple, clear, generic, and easy to promulgate formats, including posters, slides, videotapes, and pamphlets, and are further intended to serve as the basis upon which a comprehensive cargo handling methodology may be built.  
4.2 Users of these practices should avail themselves of the detailed resource information available. The practices as defined are not sufficient to form a complete cargo handling protocol.
SCOPE
1.1 These practices are intended to serve as a guide to shippers, carriers, and consignees for load planning, loading, blocking, and bracing of intermodal and unimodal cargo in surface transport. The practices are referenced to a bibliography of information concerning the above. Hazardous materials, bulk cargo, non-containerized break bulk in ocean carriage, and transport of cargo by air are not included in these practices at this time.  
1.2 These practices shall apply to cargo in surface transport on flat bed, open top, box car, truck, van, and intermodal containers.  
1.3 The practices are intended to form a framework for the safe and effective loading and unloading of cargo in intermodal and unimodal surface transport. They are not intended to provide comprehensive detail relating to specific types of cargo, but will reference to source materials wherein such detail may be found.  
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.

Standard Test Method for Vibration Testing of Intermediate Bulk Containers (IBCs) Used for Shipping Liquid Hazardous Materials (Dangerous Goods)

SIGNIFICANCE AND USE
4.1 Shipping containers are exposed to complex dynamic stresses when subjected to vibration present in transportation vehicles. Approximating the actual damage, or lack of damage, experienced in shipping may require subjecting the container(s) and contents to vibration inputs.  
4.2 Resonant responses during shipment can be severe and may lead to failure of the container and spillage or leakage of contents. Identification of critical frequencies and the nature of package stresses can aid in minimizing the effect of these occurrences.  
4.3 This vibration test method is used for the qualification of IBCs in CFR 49 and has demonstrated successful use in transportation.  
4.4 Exposure to vibration can affect the shipping container, its means of closure, and its contents. This test method allows analysis of the interaction of these components. Design modification to one or more of these components may be utilized to achieve optimum performance in the shipping environment.  
4.5 This test method is suitable for individual filled containers that are transported unrestrained on the bed of a vehicle.  
4.6 This test method is not intended for testing intermediate bulk containers at a frequency that causes the container to go into resonance.
SCOPE
1.1 This test method covers vibration testing of filled intermediate bulk containers (IBCs) intended to contain liquid hazardous materials (dangerous goods) and is suitable for testing IBCs of any design or material type. This test method is required as part of the qualification of IBCs in accordance with the United States Department of Transportation Title 49 Code of Federal Regulations (CFR) and the United Nations Recommendations on the Transport of Dangerous Goods (UN).  
1.2 This test method is appropriate for testing IBCs ranging from 450 to 3000 L (119 to 793 gal). Packagings of smaller sizes should be tested using Test Method D999 or other applicable methods.  
1.3 The ISO 2247 standard may not meet the requirements for this test method.  
1.4 This test method is based on the current information contained in 49 CFR, §178.819.  
1.5 This test method is used to determine that the IBC maintains integrity and to prevent leakage or spillage of contents during shipping. This test method may also be used as a screening tool or as a design qualification test. Other vibration methods are available to more closely simulate vibration experienced in actual transportation.  
1.6 When testing packaging designs intended for hazardous materials (dangerous goods), the user of this test method shall be trained in accordance with 49 CFR §172.700 and other applicable hazardous materials regulations such as the ICAO Technical Instructions, IMDG Code, and carrier rules such as the IATA Dangerous Goods Regulations.  
1.7 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.8 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. Specific precautionary statements are given in Section 6.  
1.9 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.

SIGNIFICANCE AND USE
4.1 This classification is intended to encourage uniformity in reporting properties of MLS and Metal Layer gaskets, to provide a common language for communications between producers and users, and to guide engineers and designers in the application and construction of commercially available gaskets. (A) This classification may also be used to classify Single Layer Steel (SLS) Gaskets.(B) Refer to Specification A666 or Specification A109/A109M for Stainless Steel and Low Carbon Steel, respectively. Other metals not referenced in the table or not covered by Specification A666 or Specification A109/A109M must be defined by the producer/user (that is, H – High Temperature Alloy).(C) Refer to Practice D1418 for general information regarding rubber coating types and use Classification D2000 to define the physical properties of the rubber. This physical property information is typically specified on the gasket drawing or the customer specification, or both.(D) Coated side as specified on part drawing.  
4.2 Suffix Table 2 is provided to allow hardness designation for Active, Inactive, or Load Stoppers.  
4.2.1 If suffixes are not to be used, only the basic callout from Table 1 is required. If a suffix is used for 1 layer, it must be specified for all layers, even if a “0” is used. It cannot be assumed that hardnesses of like layers are the same; if used, all layers must be specified separately. The first layer specified must be indicated on the part drawing. To use a hardness call-out, at the end of the base callout leave a space followed by the “HR” suffix with a series of suffix numbers to specify the hardnesses for each layer.
4.2.1.1 Example: ASTM F2325, A32ANBW11 HR252—Example from Table 1 modified to add hardness requirement for the three metal layers. Active layers 1 and 3 are designated to be the same, 1/4 hard steel. Stopper layer 2 is designated to be full hard steel.
SCOPE
1.1 This classification covers a means for specifying Multi-Layer Steel (MLS) and other Metal Layer Gaskets for Transportation Applications by application and construction. These structures are composed of one or more steel or metal layers of material, which may have coatings or embossments. Commercial materials designated as composite or enveloped gaskets are excluded from this classification and are covered by Classification F868 and Practice F336, respectively.  
1.2 Since all of the properties that contribute to gasket performance are not included, use of this classification as a basis for selecting an MLS or Metal Layer gasket is limited.  
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.
