4.1 Warning tracks are playing surfaces located on the margins of the playing area for the purpose of providing a warning to the player that he or she is approaching a hazard (commonly a fence) or out-of-bounds area. In order to provide for an effective warning track surface, the warning track must be constructed and maintained in such a manner so that the player can sense the change in texture from the regular playing surface and the warning track without having to look. This feature is very important in that the player is often visually focused on the ball during play and would not be looking at the ground as he/she is running toward the warning track. The warning track must also be constructed and maintained in such a manner that the warning track itself, or the surface transition, does not pose a hazard to the players.4.2 The warning track areas of sports fields should provide a uniform surface with good footing. The change in surface texture of the warning track from the surrounding playing surface must be of enough contrast such that the player can sense the change without looking. Most often, warning track surfaces are devoid of turf or other vegetation. However, turfed warning track areas may be used in instances where such purpose is to “warn” the player of an impending hazard where the primary playing surface is a skinned area. This may be the case in softball where the entire infield playing surface is a skinned area and a turfed warning track is used along the first base and third base fencelines. Undulations, rough surface, hard or soft surface, weeds, stones, debris, wets spots, etc. detract from a good, safe warning track. The safety and effectiveness of the warning track is largely affected by construction and maintenance procedures and this guide addresses those procedures.4.2.1 During construction, consideration should be given to factors such as the physical and chemical properties of materials used in the area, freedom from stones, sticks, and other debris, and surface drainage and internal drainage. Consideration should also be given to the surface elevation such that a drastic change is not produced by the transition from the playing surface to the warning track area which may create a tripping or falling hazard.4.2.2 Maintenance practices that influence the playability of the surface include edging, dragging, rolling, watering, vegetation control, and removal of stones and debris that may adversely affect play and safety.4.3 Those responsible for the design, construction, or maintenance, or a combination thereof, of baseball and softball fields, or play areas where the need for a warning track area has been identified, will benefit from this guide.1.1 This guide covers techniques that are appropriate for the construction and maintenance of warning track areas on sports fields. This guide provides guidance for the selection of materials, such as soil and sand for use in constructing or reconditioning warning track areas and for selection of management practices that will maintain a safe and functioning warning track. Although this guide has applications to all sports where a warning track surface may be required or desired, it has specific applications to baseball/softball.1.2 This guide does not address synthetic warning tracks such as rubberized surfaces, artificial turf, or paved surfaces.1.3 Decisions in selecting construction and maintenance techniques are influenced by local soil types, climatic factors, level of play, budget, and training/ability of management personnel.1.4 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.1.5 This standard may involve hazardous materials, operations, and equipment. 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 High quality physical product standards for color or appearance are the keystone of a successful color control program. Standards are often grouped into three major categories: product standards, intermediate production control standards, and instrument standards. This guide deals only with physical product standards. Some instrument-based color control programs use “numerical standards,” derived from instrumental measurements of a physical product standard.AbstractThis guide covers three levels of physical product standards (preparation, maintenance, and distribution) for color or geometric appearance, or both, of coatings commonly used in the coatings industry. Described here is terminology to describe each level, and techniques for generating and caring for standards. Product standards are the only standards by which products should be accepted or rejected for color or appearance. A master standard is generated from the concept color submitted by the customer. Duplicate master standards, when needed, are generated from the master standard. Working standards are generated from a duplicate master standard. They are used in the laboratory or on the production line to accept or reject the color or appearance of coatings. After initial generation, product standards must be maintained to ensure they remain valid. This guide considers the characteristics of product standards, factors to be considered in their creation, and factors to be considered in their replacement.1.1 This guide covers three levels of physical product standards for color or appearance, or both, commonly used in the coatings industry, provides terminology to describe each level, and describes techniques for generating and caring for standards.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 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.

5.1 This guide identifies the responsibilities of the fiber, fabric, and clothing manufacturers, as well as the processor, the processor's chemical supplier, and the end user.5.2 This guide describes the key components involved in an industrial laundry program for the care and maintenance of flame resistant and arc rated clothing.5.3 The guidelines in this standard will provide a processor assistance to develop a processing system that maintains the flame resistant or arc rated clothing during its useful service life.5.3.1 The development of published formulas for each fabric and level of soiling is difficult at any given point in time due to ongoing, continuous improvement of flame resistant and arc rated clothing, including new fibers, fabrics, and laundering equipment and procedures.5.4 The guide also provides suggestions as to when flame resistant or arc rated garments should be removed from service.5.5 Flame resistant or arc rated protective clothing not processed by an industrial laundry supplier are subject to a home laundry process and are subject to Guide F2757.5.5.1 When wearers choose to launder their flame resistant or arc rated protective clothing at home, the laundry supplier cannot be held responsible for the condition of the garments.1.1 This guide provides recommendations for the care and maintenance of clothing that is flame resistant or arc rated.1.2 These recommendations address the industrial laundering process. Industrial laundering is an effective cleaning process for flame resistant or arc rated clothing; follow all label care instructions. The National Institute for Occupational Safety and Health (NIOSH) recommends leaving clothing soiled with hazardous chemicals at work to be laundered by the employer or, if such clothing is washed at home, to launder separately from the family wash.1.2.1 This guide does not apply to dry cleaning of flame resistant or arc rated clothing. For more information on dry cleaning, follow label instructions or contact your garment supplier. Dry cleaning indicates cleaning by a professional dry cleaner.1.2.2 This guide does not apply to home laundering of flame resistant or arc rated clothing. For more information on home laundering, follow label instructions or contact your garment supplier. Home laundering indicates laundering in a home laundering machine. For more information on home laundering, see Guide F2757.1.3 It is important that potentially flammable contaminants are removed from garments during the wash process. If flammable contaminants are not removed, the flame resistance of the garment may be compromised. Effective cleaning and proper maintenance of the protective characteristics of flame resistant or arc rated clothing should include consideration of cleaning, repair, and replacement.1.3.1 To reduce the potential of employees wearing garments contaminated with flammable substances, the end user should analyze the soil conditions to which a wearer may be exposed, along with the effectiveness of the industrial wash procedure. If it is deemed ineffective, effective solutions should be pursued (dry cleaning, surfactants, disposable FR coveralls, etc.).1.4 It is important that the processes and materials used to launder flame resistant garments are compatible with the FR materials to ensure that the FR protection of the garment is not compromised during the laundering process.1.5 It is the responsibility of the end user to determine if their laundering method is the appropriate care and maintenance procedure for their application. (See Appendix X1 and X1.1.)1.6 This guide does not apply to specialized protective garments such as specialized firefighter turnout gear and proximity firefighter ensembles.1.7 This guide also identifies inspection criteria that are significant to the performance of flame resistant or arc rated clothing.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.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.

5.1 Introduction—Mu numbers (friction values) measured by CFME can be used as guidelines for evaluating the surface friction deterioration of runway pavements and for identifying appropriate corrective actions required for safe aircraft operations. The original levels were based on the work of the FAA/AS-90-1 (3). The report states that based on friction values from a Mu Meter Mark II using Dunlop tires, and tests conducted by NASA in the 1970s using a Boeing 727, Table 1 of Mu Meter friction level classifications for runway pavement surfaces was established for friction measurements at test speeds of 65 km/hr. Additionally, tests were conducted again with the Mu Meter Mark II outfitted with the Dico tire at 95 km/h. Then a second-order correlation was performed for the Mu Meter operating at 95 km/h and at 65 km/h resulting in the values shown in Table 2. These values were then fixed and used with correlations of other CFMEs to establish the present maintenance levels given in Table 3.2 of FAA Advisory Circular AC/150/5320-12. From the Wallops 1993 data, the IFI values were calculated and the 65 km/hr data in Table 2 was used to calculate the FM60 value for each level. The data for the two speeds for the four CFMEs in the FAA report (3) were used to establish the SMp values for each level. Then a new level, New Grooved, was added based on the differences of grooved and un-grooved sites at the NASA Wallops test facility. Table 3 is a list of these values to be the standard values FM60 and SMp for any future calibration of CFME. 5.2 Airports—Routine testing is carried out in order to obtain data for scheduling remedial work on the runway surface. A single run on either side of the centerline may be regarded as sufficient or a set of runs covering the whole width of the runway may be preferred. At 3 m spacing, the friction map which can be prepared from a set of runs of this kind provides excellent information on rubber buildup and surface polishing. Standard test speeds are typically 65 km/hr or 95 km/hr and standard test water film thickness is typically 1 mm. 1.1 This practice covers the method of calculating frictional values from correlations of continuous friction measurement equipment (CFME), using the Specification E1551 tire, for use in performing airport summer maintenance evaluations. 1.2 The practice is intended to provide a unified friction index of levels for use in harmonizing the output of devices. 1.3 Airport operators use a variety of CFMEs to assess the friction levels of their paved runway surfaces. The measurements are used to determine when the surfaces should be considered for or subjected to maintenance. However, many are built differently and produce different values when measuring the same pavement surfaces. This practice provides a method to harmonize these measurements so that the friction values generated can be used to determine the maintenance requirements as established by the operating authority. 1.4 The practice provides correlations for four maintenance levels of friction: New Design/Construction with grooves, New Design/Construction without grooves, Maintenance Planning, and Minimum Acceptable. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 ASTM International takes no position with respect to the validity of any patent rights asserted in connection with any item mentioned in this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. 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.

4.1 The process of operating any engineered system, such as monitoring wells, includes active maintenance to prevent, mitigate, or reverse deterioration. Lack of or improper maintenance can lead to well performance deficiencies (physical problems) or sample quality degradation (chemical problems). These problems are intrinsic to monitoring wells, which are often left idle for long periods of time (as long as a year), installed in non-aquifer materials, and installed to evaluate contamination that can cause locally anomalous hydrogeochemical conditions. The typical solutions for these physical and chemical problems that would be applied by owners and operators of water supply, dewatering, recharge, and other wells may not be appropriate for monitoring wells because of the need to minimize their impact on the conditions that monitoring wells were installed to evaluate.4.2 This guide covers actions and procedures, but is not an encyclopedic guide to well maintenance. Well maintenance planning and execution is highly site and well specific.4.3 The design of maintenance and rehabilitation programs and the identification of the need for rehabilitation should be based on objective observation and testing, and by individuals knowledgeable and experienced in well maintenance and rehabilitation. Users of this guide are encouraged to consult the references provided.4.4 For additional information see Test Methods D4412, D5472, D7726 and Guides D4448, D5254, D5521, D5409, D5410 and D5474.NOTE 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results.

4.1 The gasket factors are a function of leak rate; therefore, this practice generates curves. Constants for use in the ASME Boiler and Pressure Vessel Code, Section VIII, Appendix 2 code calculations are selected from these data. Specific m and y values can be selected based on a maximum desired leak rate or derived from these data as described in this procedure. This practice addresses the influence of leak rate and gasket thickness on a gasket’s ability to provide a seal initially and in operation. This practice is performed at room temperature; therefore, this practice does not account for all conditions, such as high temperature or thermal cycling or both, that bolted flange connections may be subject to in field application.4.2 This practice determines two general characteristics that are specific to the ASME design criteria. Caution should be exercised when comparing yield and maintenance factors between gasket materials, and it is recommended that the m and y curves be compared. Selecting a gasket material for use in an application should not be based exclusively on these two general characteristics. Gasket material selection for a given application should consider additional information not described in this practice, which includes, but is not limited to, chemical resistance, thermal resistance, creep relaxation, compressibility, and accommodation of thermal cycling.4.3 This practice builds upon work conducted in the Fluid Sealing Association (FSA G 605:11). The associated round robin data is provided for reference in Tables 1-4.(A) BDL = below detection limit.(A) BDL = below detection limit.1.1 This practice will establish criteria for determining loading constants that are referenced in the American Society of Mechanical Engineers (ASME) pressure vessel design (Boiler and Pressure Vessel Code, Section VIII, Divs. 1 and 2). These constants are specific to this design criterion for metallic, semi-metallic, and nonmetallic gaskets.1.2 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.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.
