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 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 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.

Standard Specification for Polymeric Piles

ABSTRACT
This specification establishes the physical and performance requirements for round and rectangular cross-section polymeric piles in axial and lateral load-bearing applications including, by not limited to, marine, waterfront, and corrosive environments. It does not apply to individual polymeric pile products, sheet piles, and other mechanically connected polymeric pile products using inter-locking systems. Covered here are six types of polymeric piles that are fabricated from materials that may be virgin, recycled, or both, as long as the finished product meets all of the criteria specified herein. These types are: Type I, polymeric only; Type II, polymeric with reinforcement in the form of chopped, milled or continuous fiber or mineral; Type III, polymeric with reinforcement in the form of metallic bars, cages, or shapes; Type IV, polymeric with reinforcement in the form of non-metallic bars or cages; Type V, polymeric composite tube with a concrete core; and Type VI, any other polymeric piling meeting the requirements stated herein and not otherwise described by Types I through V. The polymeric tiles shall adhere to specified physical attributes such as size, cross-sectional shape, length, straightness, placement of reinforcement, and surface conditions. The performance requirements which pile specimens shall conform to include creep rupture, serviceability, flexural properties, shear strength, bearing strength, design flexural stiffness, energy absorption, compressive strength, combined stresses, dimensional stability (thermal expansion), hygrothermal cycling, and flame spread index.
SCOPE
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.

Standard Classification System and Basis for Specification for Polyphthalamide (PPA) Injection Molding Materials

ABSTRACT
This specification covers the classification, testing, and requirements of polyphthalamide (PPA) materials, both virgin and recycled, suitable for injection molding. This specification is intended to be a means of calling out plastics materials used in the fabrication of end items or parts, and not for the selection of materials. The materials are classified into groups according to crystallinity, and are further subdivided into classes and grades as specified. Materials shall be sampled, prepared, and conditioned appropriately for testing, for which specimens shall conform to specified values of the following requirements: inherent viscosity; melting temperature; glass transition; tensile strength; flexural strength and modulus; Izod impact strength; deflection temperature; and moisture.
SCOPE
1.1 This classification system covers polyphthalamide (PPA) materials suitable for injection molding.  
1.2 The properties included in this classification system are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are to be specified by using suffixes as given in Section 5.  
1.3 This classification system allows for the use of recycled materials provided that all specification requirements are met.  
1.4 This classification system is intended to be a means of calling out plastics materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection can be made by those having expertise in the plastics field only after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this classification system.  
1.5 The values stated in SI units are to be regarded as the standard (see IEEE/ASTM SI-10). The values given in parentheses are for information only.  
1.6 The following precautionary caveat pertains only to the test methods portion, Section 11, of this classification system: 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 11.7.1.
Note 1: There is no known ISO equivalent to this standard. ISO 16396-1/-2 for polyamides may also be used to describe and classify these PPA materials, but the technical content is significantly different.
Note 2: ASTM Standard D6779 on polyamide materials also includes PPA materials in its coverage of various polyamide chemistries. This standard gives additional information for classification and specification for PPA compositions classified as Group 10 (PA6T/66), Group 12 (PA6T/6I/66) and Group 13 (PA6T/6I) in ASTM Standard D6779 and includes provisions for other PPA compositions to utilize the classification presented.  
1.7 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.
