Standard Terminology for Goods Movement Process (GMP) Precise Foundational Definitions

SIGNIFICANCE AND USE
3.1 The terms defined in this document and the order they are presented illustrate sequential phases of the Goods Movement Process and further subdivide into recognizable definitive milestone statuses for uniform predictable communication.
SCOPE
1.1 During the repetitive Goods Movement Process (GMP), there is a Planning Phase, an Execution Phase, and a Settlement Phase. Each phase has sub-steps that are called Milestone Statuses. The GMP is described as part of ISO 8000-119 and relates to defined transportation needs and the executing of transportation services based on those needs. This standard seeks to precisely define the milestone statuses such that even if the reader is unfamiliar with these terms, the reader will be able to relate to the exact moment of status change described.  
1.2 Standardize the Goods Movement Process into Planning, Execution, and Settlement phases.  
1.2.1 In the Planning Phase, the milestone steps are Posted, Pre-Booked, and Booked.  
1.2.2 In the Execution Phase, the milestone steps are En-Route and Delivered.  
1.2.3 In the Settlement Phase, the milestone steps are Invoiced and Archived.  
1.3 Logically sequence the terminology represented to align with the sequence in which events will generally occur in practice.  
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.

Standard Test Methods of Polyurethane Raw Materials: Determination of the Polymerized Ethylene Oxide Content of Polyether Polyols

SIGNIFICANCE AND USE
5.1 Measurements of EO content correlate to polyol reactivity (as related to primary hydroxyl content), linearity of foam rise, and hydrophilicity of the polyol and final product.
SCOPE
1.1 Test Method A—Proton Nuclear Magnetic Resonance Spectroscopy (1H NMR) measures polymerized ethylene oxide (EO) content of ethylene oxide (EO) propylene oxide (PO) polyether polyols used in flexible polyurethane foams and non-foams. It is suitable for diols initiated from glycols of EO or PO containing EO percentages >5. For triols initiated with glycerol (glycerin) and trimethylolpropane, an uncorrected EO value is obtained since both initiators have protons that contribute to the EO measurement.  
1.2 Test Method B—Carbon-13 Nuclear Magnetic Resonance Spectroscopy (13C NMR) measures the polymerized EO content of EO-PO polyether polyols used in flexible polyurethane foams and non-foams. It is suitable for diols and triols made from the commonly used initiators and containing EO percentages >5.  
1.3 The values stated in SI units are to be regarded as standard.  
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.
Note 1: There is no known ISO equivalent to this standard.

Standard Practices for Permanent Monitoring Systems for Electrical Leak Detection and Location

SIGNIFICANCE AND USE
4.1 Geomembranes are used as impermeable barriers to prevent liquids leaking out of landfills, ponds, and other containment facilities. In addition, geomembranes are also used to prevent external liquids leaking into to these types of facilities (for example, floating covers, landfill caps, and roofs of storage tanks). The liquids may contain contaminants that, if released, can cause damage to the environment or damage to the contents where protection is against leakage into the facility. In the case of a landfill cap, leakage increases the amount of leachate that the landfill can produce. Leaking liquids can erode the subgrade, causing further damage. Leakage can result in product loss or otherwise prevent the installation from performing its intended containment purpose. For these reasons, it is desirable that the geomembrane have as little leakage as practical.  
4.2 Geomembrane leaks can be caused by poor quality of the subgrade, poor quality of the material placed on the geomembrane, accidents, poor workmanship, manufacturing defects, and carelessness.  
4.3 The most significant causes of leaks in geomembranes that are covered with only water are related to construction activities, including pumps and equipment placed on the geomembrane, accidental punctures, punctures caused by traffic over rocks or debris on the geomembrane or in the subgrade, and ruptures caused by settlement during filling.  
4.4 The most significant cause of leaks in geomembranes covered with earthen materials is construction damage caused by machinery that occurs while placing the earthen material on the geomembrane. Such damage also can breach additional layers of the lining system such as geosynthetic clay liners.  
4.5 As a practical measure, other electrical leak location methods (see Guide D6747) should be used in conjunction with the permanent monitoring system to eliminate leaks in the installed geomembrane(s) as part of facility construction. Such methods must include testing ...
SCOPE
1.1 These practices describe standard procedures for using electrical methods to locate leaks in geomembranes covered with liquid, earthen materials, waste, and/or any material deposited on the geomembrane.  
1.2 These practices are intended to ensure that permanent leak detection and location systems are effective, which can result in complete containment (no leaks in the geomembrane).  
1.3 Not all sites will be easily amenable to this method, but some preparation can be performed in order to enable this method at nearly any site as outlined in Section 6. If ideal testing conditions cannot be achieved (or designed out), the method can still be performed, but any issues with site conditions must be documented.  
1.4 Permanent monitoring systems for electrical leak detection and location can be used on geomembranes installed in basins, ponds, tanks, ore and waste pads, landfill cells, landfill caps, and other containment facilities including civil engineering structures. The procedures are applicable for geomembranes made of materials such as polyethylene, polypropylene, polyvinyl chloride, chlorosulfonated polyethylene, bituminous material, and other sufficiently electrically insulating materials.  
1.5 Any permanent electrical monitoring system must detect the occurrence of a leak through the geomembrane, and it must last longer than the monitored geomembrane by nature of the concept. Therefore, all buried components and mechanical and electrical connections must be made of material either the same as the geomembrane, in case of sensors situated above geomembrane, or made from a material with a longer lifespan in cases where they are situated under the monitored geomembrane.  
1.6 Permanent electrical monitoring systems are comprised of either large mesh pads separated by nominal spaces, or a grid of sensors situated either below the geomembrane or above the geomembrane or in both positions (below and above the ge...

Standard Test Method for Measuring Warpage of Ceramic Tile

SIGNIFICANCE AND USE
5.1 This test method provides a means for determining whether or not a lot of ceramic tile meets the warpage requirements that may appear in specifications to assure satisfactory tile installations. In accordance with this test method, warpage is calculated as a percentage of the length of the edge or diagonal being tested. It is realized that the percentage values based on the overall edge length, or on the overall diagonal length of a tile will be slightly lower than those based on the distance between reference points. However, the ratio of the overall lengths to the distance between reference points will be practically constant for any particular size of tile and, therefore, the percentage values will be comparable and equally indicative of warpage.
SCOPE
1.1 This test method covers procedures for measuring the corner, diagonal, and edge warpages of ceramic tile.  
1.1.1 Tile Requirements for Corner, Diagonal, and Edge Warpage Measurement
Tile should be nominally flat, uniform in overall thickness, smooth faced, and rectangular in shape, including square.  
1.1.2 Tile Requirements for Corner Warpage Measurement
All facial edge dimensions equal to or greater than 2.36 in. (60 mm) in length.  
1.1.3 Tile Requirements for Edge and Diagonal Warpage Measurement
All facial edge dimensions equal to or greater than 2 in. (51 mm) in length.

Standard Test Methods for Cathodic Disbonding of Coated Steel

SIGNIFICANCE AND USE
4.1 Breaks or holidays in a coating applied over steel exposes the substrate to a potential corrosion cell. When the steel is subjected to cathodic protection by the polarization of the steel via sacrificial anodes or impressed current, the exposed steel at the holiday becomes the cathode in the corrosion cell. When the electrolyte is neutral or slightly alkaline, hydroxyl ions form from the reduction of oxygen and, when paired with a suitable cation from the electrolyte, form an alkaline solution. Depending on the strength of this alkaline solution and the concentration of the alkaline compound, this alkalinity may disrupt the adhesion between the coating and the steel, disbonding the coating from the steel.  
4.2 Current density of the cathodic cell also can affect the degree of cathodic disbondment. The greater the current density generated by the concentration of electrons at the anode, the greater the number of hydroxyl ions formed, thus increasing the alkalinity available for disrupting the adhesion between the coating and the steel substrate. Likewise, the concentration of oxygen in the electrolyte will affect the concentration of hydroxyl ions formed at the cathode.  
4.3 For these reasons it is often useful to measure pH, oxygen, and current density when conducting a cathodic disbondment test.
SCOPE
1.1 These test methods apply to procedures for determining the degree of disbondment of a coating from a steel substrate when placed in contact with an electrolyte and a potential is applied to the steel. Specimens may include coated steel pipe or coated flat or curved steel plate. The coating applied to the steel substrate shall be non-metallic and shall not show flow characteristics at the test temperature.  
1.2 These test methods apply to specimens that are immersed in an electrolyte bath or specimens with an attached electrolyte cell at ambient room temperature, 21 °C to 25 °C (70 °F to 77 °F), conditions. If higher temperatures are required, use Test Method G42.  
1.3 These test methods apply to methods of polarization including sacrificial anodes or impressed current applied to the steel by a rectifier.  
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.
