Standard Specification for Oil Spill Response Boom Connection: Slide Connector

Standard Specification for Oil Spill Response Boom Connection: Slide Connector

SIGNIFICANCE AND USE
5.1 The general design geometry herein defined applies to both a separate adaptor accessory mating two booms of different geometry as well as boom end connectors (see Terminology F818).  
5.2 Interconnectibility is intended to facilitate mating of oil spill response booms of various sizes, strengths, design, and manufacture.  
5.3 The use of this general design geometry in no way guarantees the effective performance of the linked boom sections, since each boom’s design and the environmental conditions at each incident govern overall performance.
SCOPE
1.1 This specification covers design criteria requirements, design geometry, material characteristics, and desirable features for oil spill response boom slide connections. These criteria are intended to define minimum mating characteristics and are not intended to be restricted to a specific configuration.  
1.2 The specification defines the geometry required to mate with typical Universal slide connectors or Specification F962 connectors with web thickness up to 0.3 in. Some very heavy-duty or PVC connectors may exceed this dimension and not be compatible.  
1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this 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.  
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 F1657/F1657M-96(2024)(Practice)
Standard Practice for Emergency Joining of Booms with Incompatible Connectors

SIGNIFICANCE AND USE
3.1 The use of this practice for the emergency joining of booms will not guarantee the effective performance of the joined boom sections, since each boom design and the environmental conditions of each incident govern the overall performance.  
3.2 Historically, different types of end connectors have been produced. This practice addresses the operational need to connect different types, during spill incidents. (Warning—Use of this practice with similar or different sizes of boom may cause the transmission of unwanted loading such as, tension loading and bending moments on certain boom parts resulting in possible premature failure of the containment system.)  
3.3 There are a wide range of boom connector configurations presently in use. These connectors were based upon some or all of the following design criteria:  
3.3.1 Connect and transfer tensile loads between boom sections,  
3.3.2 Minimize oil leakage between boom sections,  
3.3.3 Be easily connectable in the presence of dirt, oil or ice, or a combination thereof,  
3.3.4 Be quickly and easily connected and disconnected, in and out of the water,  
3.3.5 Maintain boom performance (freeboard, heave response, conformance, stability, and so forth),  
3.3.6 Be unaffected by temperature extremes,  
3.3.7 Have no protruding parts that could snag, injure, or puncture,  
3.3.8 Be light weight and buoyant,  
3.3.9 Be operatively symmetrical,  
3.3.10 Require no special tools for installation or removal,  
3.3.11 Require no loose parts for connection,  
3.3.12 Extend to the full height and draft of the boom,  
3.3.13 Resist distortion (that is, winding boom on a reel), and  
3.3.14 Be inherently safe to personnel.
SCOPE
1.1 This practice provides a standard practice for the joining of oil spill containment boom connectors in emergencies.  
1.2 The use of this connection method may adversely affect the total tensile strength of the connected booms.  
1.3 These criteria are intended to define mating requirements that will allow the emergency or occasional connection of unlike connectors.  
1.4 This practice is not intended to replace Specification F962.  
1.5 This practice does not address the compatibility of spill control equipment with spill products. It is the user's responsibility to ensure that any equipment selected is compatible with the anticipated spilled material.  
1.6 There is no guarantee that all of the connectors in use today can accept the holes spaced as required without interfering with existing bolt holes or other connector features.  
1.7 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. See Note 5 in Fig. 1—dimensions A and B are critical.

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. For a specific precautionary statement, see 3.2.

Standard Guide for Environmental Management of Underground Storage Tank Systems Storing Regulated Substances

SIGNIFICANCE AND USE
4.1 Environmentally sound management of underground storage tank systems involves a broad range of preventative maintenance activities directed toward preventing accidental releases of regulated substances, and effectively detecting and responding to such releases when, and if, they do occur. Numerous technical guidelines are presently available addressing specific procedures for release prevention and response for underground tank systems, including guidelines for tank system design, installation, operation and maintenance, leak detection, spill control, periodic equipment inspections, corrective action for affected environmental media, tank system closure, and operator training. This guide presents an overview, identifying key management considerations and referring the user to other related ASTM standards and industry guidelines for more detailed information.  
4.2 Tank System Design and Installation—The first step in environmentally sound management of tank systems is to design and install the tank system so as to minimize the potential for release of regulated substances to the environment. This guide addresses key considerations related to the types of tank systems to be used, compatibility of regulated substances to construction materials, types of spill containment and overfill prevention devices, corrosion protection, leak detection proper installation practices, and system operation.  
4.3 Preventative Maintenance—Even for properly designed and installed tank systems, practical measures are needed to detect and terminate leaks and respond to releases in a timely manner so as to minimize regulated substance losses and associated environmental effects. This guide reviews general considerations including release detection measures, possible indicators of a release, appropriate record-keeping procedures, tank system inspection, equipment testing, response planning and release control measures. Some preventative maintenance activities are recommended while ot...
SCOPE
1.1 The framework discussed in this guide is limited to facilities with underground storage tanks (USTs) storing regulated substances at ambient temperature and atmospheric pressure. This guide is not intended to provide detailed technical specifications for implementation of the approaches described in this document, nor to be used as an enforcement tool, but rather to identify the important information used for environmental management of underground tank systems. The term “must” is used where United States federal requirements apply. References to ASTM standards and other industry guidelines have been provided to address implementation of the approaches discussed in this guide. Many states and some local agencies have adopted rules that place additional responsibilities on the owners/operators of UST systems. Refer to state and local regulations that may contain additional requirements. It is not possible to identify all considerations or combinations of conditions pertinent to a unique underground storage tank system.

Standard Specification for Polyethylene Upright Storage Tanks

ABSTRACT
This specification covers flat-bottom, upright, cylindrical tanks molded in one-piece seamless construction by rotational molding. The tanks are molded from polyethylene for above ground, vertical installation and are capable of containing aggressive chemicals at atmospheric pressure. This specification does not cover the design of vessels intended for use at pressures other than atmospheric pressure. Furthermore, this specification does not cover the design of portable tanks and is not for vessels intended for use with liquids heated above their flash points in continuous service. Special design considerations not covered in this specification shall be given to vessels subject to superimposed mechanical forces, such as seismic forces, wind load or agitation; to vessels subject to service above specified temperature; and vessels subject to specified superimposed pressure of water. Low-temperature impact test shall be performed on rotational-molded polyethylene tanks. The test method is used on tanks molded from both the crosslinked and non-crosslinked polyethylenes. Dart drop impact test shall be performed to determine the quality of the tank. O-xylene-insoluble fraction or gel test shall be performed on crosslinked polyethylene. Visual inspection and water test shall also be performed on the samples.

Standard Practice for Measuring the Ultrasonic Velocity in Polyethylene Tank Walls Using Lateral Longitudinal (LCR) Waves

ABSTRACT
This practice covers a procedure for measuring the ultrasonic velocities in the outer wall of polyethylene storage tanks. The practice is intended for application to the outer surfaces of the wall of polyethylene tanks. An angle beam lateral longitudinal (LCR) wave is excited with wedges along a circumferential chord of the tank wall. A digital ultrasonic flaw detector is used with sending-receiving search units in through transmission mode. The observed velocity is temperature corrected and compared to the expected velocity for a new, unexposed sample of material, which is the same as the material being evaluated. The difference between the observed and temperature corrected velocities determines the degree of UV exposure of the tank.
SIGNIFICANCE AND USE
5.1 Measuring the velocity of ultrasound in materials is a unique method for determining nondestructively the physical properties, which can vary due to both manufacturing processes and environmental attack. Velocity is directly related to the elastic moduli, which can vary based on environmental exposure and manufacturing process, The LCR method described herein is able to measure the velocity between two adjacent points on a surface and therefore is independent of the conditions on the opposite wall. Applications of the method beyond polymer tanks will undoubtedly be developed and examination may occur in the production line as well as in the in-service mode.
SCOPE
1.1 This practice covers a procedure for measuring the ultrasonic velocities in the outer wall of polyethylene storage tanks. An angle beam lateral longitudinal (LCR) wave is excited with wedges along a circumferential chord of the tank wall. A digital ultrasonic flaw detector is used with sending-receiving search units in through transmission mode. The observed velocity is temperature corrected and compared to the expected velocity for a new, unexposed sample of material which is the same as the material being evaluated. The difference between the observed and temperature corrected velocities determines the degree of UV exposure of the tank.  
1.2 The practice is intended for application to the outer surfaces of the wall of polyethylene tanks. Degradation typically occurs in an outer layer approximately 3.2 mm (0.125 in.) thick. Since the technique does not interrogate the inside wall of the tank, wall thickness is not a consideration other than to be aware of possible guided (Lamb) wave effects or reflections off of the inner tank wall. No special surface preparation is necessary beyond wiping the area with a clean rag. Inside wall properties are not important since the longitudinal wave does not strike this surface. The excitation of Lamb waves must be avoided by choosing an excitation frequency such that the ratio of wavelength to wall thickness is one fifth or less.  
1.3 UV degradation on the outer surface causes a stiffening of the material and an increase in Young's modulus and the longitudinal wave velocity.  
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered 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.
