Standard Test Method for Sulfur in Liquefied Petroleum Gases (Oxy-Hydrogen Burner or Lamp) (Withdrawn 2016)

Standard Test Method for Sulfur in Liquefied Petroleum Gases (Oxy-Hydrogen Burner or Lamp) (Withdrawn 2016)

SIGNIFICANCE AND USE
It is important to have the sulfur content of liquefied petroleum gases at low enough concentration to meet government regulations. The presence of sulfur can result in corrosion of metal surfaces. Sulfur can be poisonous to catalysts in subsequent processing.
SCOPE
1.1 This test method covers the determination of total sulfur in liquefied petroleum gases containing more than 1 μg/g. Specimens should not contain more than 100 μg/g of halogens.
1.2 To attain the quantitative detectability that the test method is capable of, stringent techniques must be employed and all possible sources of sulfur contamination must be eliminated. In particular, cleaning agents, such as common household detergents which contain sulfates, should be avoided.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
This test method covers the determination of total sulfur in liquefied petroleum gases containing more than 1 μg/g. Specimens should not contain more than 100 μg/g of halogens.
Formerly under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, this test method was withdrawn in June 2016 because it is archaic and not used in the industry.

Standard Test Methods and Definitions for Mechanical Testing of Steel Products

SIGNIFICANCE AND USE
4.1 The primary use of these test methods is testing to determine the specified mechanical properties of steel, stainless steel, and related alloy products for the evaluation of conformance of such products to a material specification under the jurisdiction of ASTM Committee A01 and its subcommittees as designated by a purchaser in a purchase order or contract.  
4.1.1 These test methods may be and are used by other ASTM Committees and other standards writing bodies for the purpose of conformance testing.  
4.1.2 The material condition at the time of testing, sampling frequency, specimen location and orientation, reporting requirements, and other test parameters are contained in the pertinent material specification or in a general requirement specification for the particular product form.  
4.1.3 Some material specifications require the use of additional test methods not described herein; in such cases, the required test method is described in that material specification or by reference to another appropriate test method standard.  
4.2 These test methods are also suitable to be used for testing of steel, stainless steel and related alloy materials for other purposes, such as incoming material acceptance testing by the purchaser or evaluation of components after service exposure.  
4.2.1 As with any mechanical testing, deviations from either specification limits or expected as-manufactured properties can occur for valid reasons besides deficiency of the original as-fabricated product. These reasons include, but are not limited to: subsequent service degradation from environmental exposure (for example, temperature, corrosion); static or cyclic service stress effects, mechanically-induced damage, material inhomogeneity, anisotropic structure, natural aging of select alloys, further processing not included in the specification, sampling limitations, and measuring equipment calibration uncertainty. There is statistical variation in all aspects of mechanical testin...
SCOPE
1.1 These test methods2 cover procedures and definitions for the mechanical testing of steels, stainless steels, and related alloys. The various mechanical tests herein described are used to determine properties required in the product specifications. Variations in testing methods are to be avoided, and standard methods of testing are to be followed to obtain reproducible and comparable results.

ASTM C1306/C1306M-08(2023)(Test Method)
Standard Test Method for Hydrostatic Pressure Resistance of a Liquid-Applied Waterproofing Membrane

SIGNIFICANCE AND USE
5.1 This test method is used as a screening tool to determine the hydrostatic pressure to which a liquid-applied waterproofing membrane may be subjected without failing when stretched over a crack in the substrate. This test method discriminates between a membrane that is very resistant to hydrostatic pressure and one that is not. Because of the variability inherent in this test method, it is not recommended that this test method be used to set a numerical standard for hydrostatic pressure resistance. No prediction of durability at lower hydrostatic pressures can be made when using the results of this test method.
SCOPE
1.1 This test method describes a laboratory procedure for determining the resistance of a waterproofing membrane to hydrostatic pressure.  
1.2 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.  
1.3 There are no ISO standards similar or equivalent to this ASTM standard.  
1.4 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 nonconformance 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.

ASTM A480/A480M-23a(Specification)
Standard Specification for General Requirements for Flat-Rolled Stainless and Heat-Resisting Steel Plate, Sheet, and Strip

ABSTRACT
This specification covers general requirements for flat-rolled stainless and heat-resisting steel plate, sheet, and strip. The steel shall be made by one of the following processes: electric-arc, electric-induction, or other suitable processes. Heat and product analyses shall conform to the chemical requirements for each of the specific elements. The material shall undergo mechanical tests such as tension test, hardness test, and bend test. Special tests like intergranular corrosion test, permeability test, Charpy impact testing and tests for detrimental intermetallic phases in wrought duplex stainless steels shall be also be performed when required.
SCOPE
1.1 This specification2 covers a group of general requirements that, unless otherwise specified in the purchase order or in an individual specification, shall apply to rolled steel plate, sheet, and strip, under each of the following specifications issued by ASTM: Specifications A240/A240M, A263, A264, A265, A666, A693, A793, and A895.  
1.2 In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail. In the case of conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail. The purchase order requirements shall not take precedence if they, in any way, violate the requirements of the product specification or this specification; for example, by waiving a test requirement or by making a test requirement less stringent.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The SI units are shown in brackets, except that when A480M is specified, Annex A3 shall apply for the dimensional tolerances and not the bracketed SI values in Annex A2. 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 specification and the applicable material specifications are expressed in both inch-pound and SI units. However, unless the order specifies the applicable “M” specification designation [SI units], the material shall be furnished in inch-pound units.  
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.

ASTM D5141-23(Test Method)
Standard Test Method for Determining Filtering Efficiency and Flow Rate of the Filtration Component of a Sediment Retention Device

SIGNIFICANCE AND USE
5.1 This test method is used to determine the filtering efficiency and flow rate of the filtration component of a sediment retention device, such as a silt fence, a silt barrier, or a silt curtain, for specific soil tested.  
5.2 This test method may be used for the design of the filtration component of a sediment retention device to meet requirements of regulatory agencies in filtering efficiency or flow rate for the specific soil tested.  
5.2.1 The designer can use this test method to determine the spacing between sediment retention devices.  
5.3 This test method is intended for performance evaluation, as the results will depend on the specific soil evaluated. Unless testing with the default soil is desired, it is recommended that the user or representative perform the test to pre-approve products, as sediment retention device manufacturers are not typically equipped to handle or test soil requirements.  
5.4 This test method provides a means of evaluating the filtration component of sediment retention devices with different soils under various conditions that simulate the conditions that exist in a sediment retention device installation. This test method may be used to simulate several storm events on the same sediment retention device specimen. Therefore, the number of times this test is repeated per specimen is dependent upon the user and the site conditions.
SCOPE
1.1 This test method is used to determine the filtering efficiency and the flow rate of the filtration component of a sediment retention device, such as a silt fence, silt barrier, or inlet protector.  
1.1.1 The results are shown as a percentage for filtering efficiency and cubic metres per square metre per minute (m3/m2/min) or gallons per square foot per minute (gal/ft2/min) for flow rate.  
1.1.2 The filtering efficiency indicates the percent of sediment removed from sediment-laden water.  
1.1.3 The flow rate is the average rate of passage of the sediment-laden water through the filtration component of a sediment retention device.  
1.2 This test method requires several specialized pieces of equipment, such as an integrated water sampler and an analytical balance, or a vacuum filtration system.
