4.1 With the rapid expansion of the commercial photovoltaic market and the various standards and independent certification entities evolving, a consensus standard practice for the ICOMP process is needed to bring consistency to the market.4.2 Investors and insurance companies need consistency of product and standards to reduce costs of capital and underwriting. Use of a consensus standard practice is expected to improve consistency and reduce risk for investors.4.3 Photovoltaic systems operate in harsh environments that are not typical for electrical equipment and generally inconsistent with electrical contractor experience. Documented processes are needed to ensure performance and durability of the systems over the long operating life.4.4 The goal of this practice is to implement processes to improve safety and reliability, reduce lifecycle costs (commonly referred to as Levelized Cost of Energy or LCOE), and encourage the development of feedback loops for continuous improvement of results.4.5 This practice may be applied during any or all phases of the PV System Lifecycle (refer to Section 5). A record of the activities carried out according to this practice shall be included in the Report (refer to Section 8).1.1 This practice details the minimum requirements for installation, commissioning, operations, and maintenance processes to ensure safe and reliable power generation for the expected life of the photovoltaic system. Specifically dealing with commercial photovoltaic installations, this practice covers a broad spectrum of designs and applications and is focused on the proper process to ensure quality.1.2 This practice does not cover the electrical aspects of installation found in existing and national codes and does not replace or supersede details of electrical installation covered by the same. The practice does address the integration of best practices into design and construction.1.3 This practice shall not dictate specific design criteria or favor any product or technology.1.4 This practice shall be focused on the proper, documented process required to build and operate a quality PV plant as defined in Section 3.1.5 Integration of best practices shall be relevant to this standard and promote a mechanism for rapid evolution and reaction to changes or events. Conformity assessment for PV power plants is being developed through the IEC System for Certification to Standards Relating to Equipment for Use in Renewable Energy Applications (IECRE System). Sandia Labs has developed several model documents that may be adopted as acceptable consensus standards through other standards development organizations.1.6 The standard is divided into three key areas:1.6.1 Design, engineering, and construction of the PV plant. Systems should be designed with operation and maintenance (O&M) in mind. Further standards should be developed for building integrated or building mounted systems, modules with embedded power electronics, lightweight flexible modules, or other specific components.1.6.2 Commissioning, testing, and approval for power generation (Utility Witness Testing). Standards for owner acceptance will also be addressed.1.6.3 O&M of the PV plant including performance monitoring, periodic inspection, preventive maintenance, and periodic re-commissioning.1.7 Safety and hazard considerations unique to this application, such as worker fall protection, electrical exposure, accessibility of modules, and roof clearance (around the perimeter of the array) are addressed by other codes, standards, or authorities having jurisdiction.1.8 This practice provides guidelines for minimum processes required and must be used in conjunction with applicable codes and standards, government regulations, manufacturer requirements, and best practices.1.9 This practice is not intended to replace or supersede any other applicable local codes, standards or Licensed Design Professional instructions for a given installation.1.10 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.1.11 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 skinned areas of baseball and softball fields should provide a uniform playing surface of high quality. Ball bounce should be true and predictable. Footing and sliding properties should favor optimum performance of players. Undulations, rough surface, hard or soft surfaces, weeds, stones, and wet spots detract from good play. Playing surface quality is largely affected by construction and maintenance procedures, and this standard guide addresses those procedures. While warning tracks are a type of skinned area found on baseball and softball fields, this standard does not apply to warning tracks. A separate standard, Guide F2270, presents information pertaining to warning tracks.4.1.1 During construction, consideration should be given to factors such as the physical and chemical properties of materials used in the area, freedom from stones and other debris, and surface and internal drainage.4.1.2 Maintenance practices that influence the playability of the surface include edging, dragging, rolling, watering, vegetation control, brushing or hosing to prevent buildup of a lip of mineral matter in turfgrass at the skinned/turfed edges, and removal of stones and debris that may adversely affect play and safety.4.2 Those responsible for the design, construction, or maintenance, or a combination thereof, of skinned areas on baseball and softball fields will benefit from this guide.4.3 This guide provides flexibility in choices of procedures and can be used to cover a variety of use and budget levels.1.1 This guide covers techniques that are appropriate for the construction and maintenance of skinned areas on baseball and softball fields. This guide provides guidance for the selection of materials, such as soil, sand, gravel, crushed stone, crushed brick, calcined clay, calcined diatomaceous earth, vitrified clay, etc., for use in constructing or reconditioning skinned areas and for the selection of management practices that will maintain a safe and playable skinned surface. Although this guide is specific to baseball/softball, it has application to other sports where ball bounce, ball roll, or player footing, or a combination thereof, are of importance.1.2 Decisions in selecting construction and maintenance techniques are influenced by existing soil types, climatic factors, level of play, intensity of use, equipment available, budget, and training and ability of management personnel.1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.1.4 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.

5.1 This guide is intended for use by employees of the end user, such as safety personnel or program administrators, who have chosen to implement a home-laundered flame resistant or arc rated clothing program.5.2 This guide describes the key components involved in the home care and maintenance of flame resistant or arc rated clothing. The decision to home launder flame resistant or arc rated clothing is part of an overall hazard analysis. It should include the nature of the hazard, the soils, and any chemicals present in the workplace. Conditions may exist that require work apparel to be cleaned at work or professionally due to the risk of contamination of the home or waste water caused by the wearer’s on-the-job exposure.5.3 The guide provides the end user assistance to follow laundering methods that will clean the garment and maintain the flame resistant or arc rated characteristics of the clothing during its useful service life. The guide also provides suggestions for increasing the wear life, appearance, and function of the clothing.5.4 The guide also provides suggestions as to when flame resistant or arc rated garments should be removed from service.5.5 The guide provides direction on proper garment repair, modification, and permanent removal from service.1.1 This guide provides recommendations for home laundering of clothing that is flame resistant or arc rated.
