The procedure described in this practice is designed to provide guidance for evaluating the effects of outdoor exposure on varnishes applied to wooden substrates. For many products, fixed angle exposures will produce higher degradation rates than the normal end use of the material.The degradation rate produced by this procedure depends on the season of the exposure and geographical location. Because outdoor weather conditions vary from season to season and year to year, this practice is not reliable for establishing absolute performance ratings for varnishes. The practice should be used only for comparing the relative performance of varnishes exposed at the same time and same location.1.1 This practice covers the procedure for evaluating durability of varnishes applied to a wooden substrate.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 and health practices and determine the applicability of regulatory limitations prior to use.
4.1 Tests and criteria as outlined determine the overall usability and stability of chairs in an environment simulating the conditions of use.4.2 Tests simulate two types of surfaces:4.2.1 Smooth surfaces such as linoleum, wet pool decks, etc. The glass testing base (Fig. 2) is used to simulate this surface.NOTE 1: A = poly(methyl methacrylate) sheet (see standard specifications); B = AC exterior glue fir plywood (see standard specifications).1.1 These requirements establish nationally recognized performance requirements for Class A (residential) and Class B (nonresidential) plastic chairs intended for outdoor use.1.2 These requirements do not address conditions that affect the performance of the chair beyond the manufacturing site.1.3 These requirements are not applicable to chaises, multipositional chairs, upholstered chairs, or other types of furniture.1.4 These requirements cover the physical performance of product regarding the aspects of outdoor weathering, impact, static load, and rear leg testing.1.5 Products may be manufactured from recycled plastics as long as the performance requirements are met.1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.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 and health practices and determine the applicability of regulatory limitations prior to use.
1.1 This guide covers the preparation of a formal plan for measurement of outdoor sound levels. A documented, detailed plan is highly desirable and useful for major environmental noise studies requiring measurements at several locations over a long period. This guide is intended primarily for use in such cases. Many simple measurements can be made without extensive prior planning or documentation. It is recommended that persons or organizations routinely performing such measurements draft and use a brief generic plan based on, but not referencing, this guide. Note 1The extent of planning and plan documentation should be consistent with the budget and needs of the project. In a large measurement program it is possible that use of a formal measurement plan could result in cost savings greater than the cost of preparing the plan. A formal documented plan can be prepared for even the simplest measurement. However, on a small project, the cost of preparation of a formal plan may not be cost effective. In such cases, plan documentation could be limited to inclusion in the final report.1.1.1 This guide addresses the following aspects of outdoor sound level measurements:1.1.2 Test Method E 1503 for Conducting Outdoor Sound Measurements Using a Digital Statistical Analysis System addresses listed aspects of outdoor sound level measurements for situations that are normally encountered. Many other formal and informal practices also address most of these issues. However, there is sometimes a need to depart from the normal methods in order to accommodate a special situation or a regulatory requirement. This guide provides options that are technically correct for specific situations, and provides the information needed for selecting appropriate options.1.1.3 This guide may be used when planning a program for obtaining either a single measurement set of sound level data or multiple sets of data, as well as related supporting data.1.2 Measurements that may be planned using this guide include, but are not limited, to the following:1.2.1 Characterization of the acoustical environment of a site.1.2.2 Characterization of the sound emissions of a specific sound source that exhibits a temporal variation in sound output.1.2.3 Measurement of low-frequency sound (infra-sound) is included because it is sometimes implicated in driving structural vibration that translates to audible interior sound.1.2.4 Measurement of impulsive sound and sound with significant tonal content.1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.
The intended use of this practice is for chain link fencing of varying heights and designs to be used to enclose a sports field, sport court or recreation facility including the internal fencing required for safety, separation of activities, security, crowd control, access and egress or other requirements.Consideration should be given to fence offset distances from the activity field to provide a safety area for the participants and viewers.This practice is not intended for applications where fencing higher than 12 ft (3660 mm) is desired by the owner.Follow Guide F 1553 format to specify the chain link fence material and installation.Warning Regarding Windscreens and Added Fence Padding—If windscreens or padding are to be installed at the time of fence erection or at a later time, it is advisable to use stronger framework, closer post spacing or back bracing of posts depending on the type of screening material to be used, area of the fence covered and the local wind and weather conditions. Post size and spacing based on wind load can be calculated using the Chain Link Fence Manufacturers Institute’(CLFMI) Guide WL 2445.1.1 This practice is designed to be used for developing the chain-link fence, design, layout and installation for sports and recreation facilities such as sports fields, sports courts, waterfront areas, docks and marinas and other specific facilities.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.
