Standard Specification for Rigid Poly (Vinyl Chloride) (PVC) Exterior Profiles Used for Fencing and Railing

ABSTRACT
This specification deals with rigid poly vinyl-chloride (PVC) exterior profiles used for agricultural, commercial, residential fencing and railing. The material used in these exterior profiles is limited to rigid poly (vinyl chloride) (PVC) compounds in a single homogeneous extrusion or in a coextrusion of two or more PVC compounds in distinct layers. Loadbearing characteristics for fence and railing assemblies are not addressed within this specification (for example, windload, horizontal or vertical guardrail loading). Materials shall be tested and shall conform to requirements for the material properties and physical properties, including dimensional tolerances, extrusion quality, and weatherability. Methods for testing and for identifying exterior profile extrusions, such as impact resistance, warp, dimensional stability, and impact test on weathered specimen that comply with this specification are also provided.
SIGNIFICANCE AND USE
4.1 The purpose of this specification is to establish a recognized standard of quality for rigid poly vinyl chloride (PVC) exterior profiles for use in assembling agricultural, commercial, and residential fencing and railing. The term “PVC fence” refers to complete fencing and railings systems in which the primary structural members such as posts, rails, spindles, pickets, and gates are made from PVC exterior profiles. Accessory components (not included in this specification), including bolts, screws, hinges, latches, caps, and brackets, may be made from PVC or non-PVC materials, or both. The information contained in this specification is intended to be helpful to producers, distributors, and users and to promote understanding between purchasers and sellers.
SCOPE
1.1 This specification establishes requirements for the material properties and physical properties, including dimensional tolerances, extrusion quality, and weatherability, of rigid poly vinyl-chloride (PVC) exterior profiles used for agricultural, commercial, residential fencing and railing. Methods for testing and for identifying exterior profile extrusions that comply with this specification are also provided.  
Note 1: Information with regard to application, assembly, and installation should be obtained from the manufacturer or in accordance with Practice F1999, or both.
Note 2: Loadbearing characteristics for fence and railing assemblies are not addressed within this specification (for example, windload, horizontal or vertical guardrail loading).  
1.2 The material used in these exterior profiles is limited to rigid poly (vinyl chloride) (PVC) compounds in a single homogeneous extrusion or in a coextrusion of two or more PVC compounds in distinct layers.  
1.3 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are provided for information only.  
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.

ASTM D2659-16(2023)(Test Method)
Standard Test Method for Column Crush Properties of Blown Thermoplastic Containers

SIGNIFICANCE AND USE
4.1 Column crush tests only provide information about the crush properties of blown thermoplastic containers when employed under conditions approximating those under which the tests are conducted.  
4.2 The column crush properties include the crushing yield load, deflection at crushing yield load, crushing load at failure, and apparent crushing stiffness. Blown thermoplastic containers made from materials that possess a low order of ductility can fail in crushing by brittle fracture. In such cases, the crushing yield load is equivalent to the crushing load at failure. Blown thermoplastic containers made of ductile materials do not always exhibit a crushing load at failure although they will normally provide a crushing yield load value.  
4.3 Column crush tests provide a standard method of obtaining data for research and development, applications, design, quality control, acceptance or rejection under specifications, and special purposes. The tests cannot be considered significant for engineering design in applications differing widely from the load - time scale of the standard test. Such applications require additional tests such as impact, creep, and fatigue.
SCOPE
1.1 This test method covers the determination of mechanical properties of blown thermoplastic containers, whether blown commercially or in the laboratory, loaded under columnar crush conditions at a constant rate of compressive deflection.
Note 1: Although this test method was developed specifically for blow-molded containers, the general procedure can also be applied to containers of suitable geometries produced by other means, for example, thermoforming, injection molding, etc.  
1.2 The values stated in SI units are to be regarded as the standard.  
Note 2: There is no known ISO equivalent to this 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.

Standard Test Method for Environmental Stress-Crack Resistance of Blow-Molded Polyethylene Containers

SIGNIFICANCE AND USE
5.1 When properly used, these procedures serve to isolate such factors as material, blow-molding conditions, post-treatment, and so forth, on the stress-crack resistance of the container.  
5.2 Environmental stress cracking of blow-molded containers is governed by many factors. Since variance of any of these factors can change the environmental stress-crack resistance of the container, the test results are representative only of a given test performed under defined conditions in the laboratory. The reproducibility of results between laboratories on containers made on more than one machine from more than one mold has not been established.  
5.3 Results can be used for estimating the shelf life of blow-molded containers in terms of their resistance to environmental stress cracking provided this is done against a rigorous background of practical field experience and reproducible test data.
SCOPE
1.1 Under certain conditions of stress, and in the presence of environments such as soaps, wetting agents, oils, or detergents, blow-molded polyethylene containers exhibit mechanical failure by cracking at stresses appreciably below those that would cause cracking in the absence of these environments.  
1.2 This test method measures the environmental stress crack resistance of blow-molded containers, which is the summation of the influence of container design, resin, blow-molding conditions, post treatment, or other factors that can affect this property. Three procedures are provided as follows:  
1.2.1 Procedure A, Stress-Crack Resistance of Containers to Potential Stress-cracking Liquids—This procedure is particularly useful for determining the effect of container design on stress-crack resistance or the stress-crack resistance of a proposed container that contains a liquid product.  
1.2.2 Procedure B, Stress-Crack Resistance of a Specific Container to Polyoxyethylated Nonylphenol (CAS 68412-54-4), a Stress-Cracking Agent—The conditions of test described in this procedure are designed for testing containers made from Class 3 polyethylene Specification D4976. Therefore, this procedure is recommended for containers made from Class 3 polyethylene only. This procedure is particularly useful for determining the effect of resin on the stress-crack resistance of the container.  
1.2.3 Procedure C, Controlled Elevated Pressure Stress-Crack Resistance of a Specific Container to Polyoxyethylated Nonylphenol (CAS 68412-54-4), a Stress-Cracking Agent—The internal pressure is controlled at a constant elevated level.
Note 1: There are environmental concerns regarding the disposal of Polyoxyethylated Nonylphenol (Nonylphenoxy poly(ethyleneoxy) ethanol (CAS 68412-54-4), for example, Igepal CO-630). Users are advised to consult their supplier or local environmental office and follow the guidelines provided for the proper disposal of this chemical.  
1.3 These procedures are not designed to test the propensity for environmental stress cracking in the neck of containers, such as when the neck is subjected to a controlled strain by inserting a plug.  
1.4 The values stated in SI units are to be regarded as standard.  
Note 2: There is no known ISO equivalent to this 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. Specific precautionary statements are given in Section 8 and Note 1.  
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.

Standard Guide for Use of High Solids Content, Cold Liquid-Applied Elastomeric Waterproofing Membrane with an Integral Wearing Surface

SIGNIFICANCE AND USE
4.1 This guide is divided into two sections which provide design and specification guidelines for the use of a cold liquid-applied elastomeric membrane with integral wearing surface for waterproofing building decks in building areas to be occupied by personnel, vehicles, or equipment.  
4.2 The intent of Sections 5 – 11, Design Considerations, is to provide information and design guidelines where a waterproofing membrane with integral wearing surface is to be used. The intent of the remaining sections is to provide minimum guide specifications for the use of the purchaser and the seller in contract documents.  
4.3 Where the state of the art is such that criteria for a particular condition is not as yet firmly established or has numerous variables that require consideration, reference is made to the applicable portion of Sections 5 – 11 that covers the particular area of concern. Section 16 describes the repair, rehabilitation, and replacement of the membrane.
SCOPE
1.1 This guide describes the design and installation of cold liquid-applied elastomeric waterproofing membrane systems that have an integral wearing surface. The cold liquid-applied elastomeric waterproofing membrane (membrane) to which this guide refers is specified in Specification C957/C957M.  
1.2 Concrete Slab-on-Grade—Waterproofing the upper surface of a concrete slab-on-grade presents special problems due to the possibility of negative hydrostatic pressure causing loss of bond to the substrate. Consideration of these problems is beyond the scope of this guide. Consult the membrane manufacturer for recommendations when this situation exists.  
1.3 The committee having jurisdiction for this guide is not aware of any similar ISO standard.  
1.4 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 nonconformance with the 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. For specific hazard statements, see 15.4.  
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.

Standard Test Method for Drop Impact Resistance of Blow-Molded Thermoplastic Containers

SIGNIFICANCE AND USE
5.1 These procedures provide a means to assess the drop impact resistance of the group or lot of blown containers from which the test specimens were selected.  
5.2 It is acceptable to use these procedures for routine inspection purposes.  
5.3 These procedures will evaluate the combined effect of construction, materials, and processing conditions on the impact resistance of the blown containers.  
5.4 Before proceeding with this test method, reference the specification of the material being tested. Any test specimen preparation, conditioning, dimensions, or testing parameters, or combination thereof, covered in the materials specification shall take precedence over those mentioned in this test method. If there are no material specifications, then the default conditions apply.
SCOPE
1.1 This test method provides a means to assess the drop impact resistance of water-filled, blow-molded thermoplastic containers, which is a summation of the effects of material, manufacturing conditions, container design, and perhaps other factors.  
1.2 Two procedures are provided as follows:  
1.2.1 Procedure A, Static Drop Height Method—This procedure is particularly useful for quality control since it is quick.  
1.2.2 Procedure B, Bruceton Staircase Method—This procedure is used to determine the mean failure height and the standard deviation of the distribution.  
1.3 The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are for information only.  
Note 1: There is no known ISO equivalent to 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.

1.1 This specification addresses the use of round and rectangular cross-section polymeric piles in axial and lateral load-bearing applications, including but not limited to marine, waterfront, and corrosive environments.  
1.2 This specification is only applicable to individual polymeric pile products. Sheet pile and other mechanically connected polymeric pile products using inter-locking systems, are not part of this specification.  
1.3 The piling products considered herein are characterized by the use of polymers, whereby (1) the pile strength or stiffness requires the inclusion of the polymer, or (2) a minimum of fifty percent (50 %) of the weight or volume is derived from the polymer. The type classifications of polymeric piles described in Section 4 show how they can be reinforced by composite design for increased stiffness or strength.  
1.4 This specification covers polymeric piles fabricated from materials that are virgin, recycled, or both, as long as the finished product meets all of the criteria specified herein. Diverse types and combinations of inorganic filler systems are permitted in the manufacturing of polymeric piling products. Inorganic fillers include such materials as talc, mica, silica, wollastonite, calcium carbonate, etc. Pilings are often placed in service where they will be subjected to continuous damp or wet exposure conditions. Due to concerns of water sensitivity and possible affects on mechanical properties in such service conditions, organic fillers, including lignocellulosic materials such as those made or derived from wood, wood flour, flax shive, rice hulls, wheat straw, and combinations thereof, are not permitted in the manufacturing of polymeric piling products.  
1.5 The values are stated in inch-pound units as these are currently the most common units used by the construction industry.  
1.6 Polymeric piles under this specification are designed using design stresses determined in accordance with Test Methods D6108, D6109, and D6112 and procedures contained within this specification unless otherwise specified.  
1.7 Although in some instances it will be an important component of the pile design, frictional properties are currently beyond the scope of this document.  
1.8 Criteria for design are included as part of this specification for polymeric piles. Certain Types and...

Standard Test Method for Measurement of Fines and Dust Particles on Plastic Pellets by Wet Analysis

SIGNIFICANCE AND USE
5.1 Molding and extruding plastic pellets require dust free, dry pellets to prevent processing problems. Plastic producers try to remove the dust and streamers with dust removal systems prior to packaging and loading. How to accurately measure dust and streamer content in plastic pellets is an important quality control issue.  
5.2 Particle size analysis is used to determine a percentage of particle size distribution from a representative sample of the whole. In terms of size analysis concerning plastic pellets, sieving is used to determine the dust content in the range of 500 to 2000 micron. Test Method D1921, Test Method B, is used to determine this type of particle sizing.  
5.3 After dry sieve analysis, particles smaller than 500 microns need to be analyzed by wet method. A fresh sample shall be used for wet analysis. This test method allows washing down the fines attached to the pellets by electrostatic forces.  
5.4 The wet analysis provides accurate quantification of small to large amounts of fines, negating static effects, and eliminating detrimental effects of mechanical agitation. A wet analysis must be employed to accurately quantify lower PPM dust levels in plastic pellets.
SCOPE
1.1 This test method measures the amount of fine particles adhered on plastic pellets or granules in which they are commonly produced and supplied. The lower limit of this test method is restricted only by the porosity of the filter disc used to capture the particle size being quantified.  
1.2 The wet analysis technique allows for separation and collection of statically charged particles by liquid wash and filtration methods. This must be performed under standard laboratory conditions.  
1.3 The values stated in SI units are to be regarded as standard.  
1.4 This test method describes an essential practice to check the quality of plastics once the production cycle is terminated and to evaluate the performance of pellet cleaning systems or of the special pneumatic conveying systems for the distinct size fractions below 500 micron 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.
Note 1: There is no known ISO equivalent to this standard.  
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.
