ASTM D2103 Standard Specification for Polyethylene Film and Sheeting

Get Certified ASTM D2103 Testing for Reliable Polyethylene Film Evaluation 

The ASTM D2103 test is a standardized method of classifying and evaluating polyethylene film. The laboratory can measure properties such as density, impact strength, kinetic coefficient of friction, haze, and nominal thickness. Skilled technicians use calibrated equipment and appropriate ASTM test methods to provide consistent data. The results can be used for material classification, quality control, product verification, and specification compliance.

What is the scope of ASTM D2103? 

ASTM D2103 provides a classification for PE film based on specified physical properties. The present edition covers polyethylene films up to 0.254 mm (0.010 in.) thick and allows for additives including pigments, stabilizers, and surface property-enhancing materials. The specification groups films into five categories that are designated by a 5-digit number to define density, impact strength, kinetic coefficient of friction, haze, and nominal thickness.

The scope of ASTM D2103 includes:

• Material: Polyethylene film, whether including plastic film additives, pigments, stabilizers, or polyethylene reclaimed feedstock, provided the following requirements are met when applicable. 
• Objective: To create a common classification and specification for polyethylene film according to defined physical properties. 
• Property measurement: density, impact strength, nominal thickness, applicable visual quality characteristics, kinetic coefficient of friction, haze, yield 
• Method: Test conducted according to ASTM D2103 and related ASTM methods, including applicable density, impact, friction, haze, and dimensional testing. 
• Result: Film receives a five-digit type designation and is checked against the physical and workmanship requirements. 
• Test limitations: The specification covers the properties and requirements as outlined by ASTM D2103, but other properties and requirements may need to be addressed by other ASTM test methods or by product-specific specifications. 
• Environmental: Personnel conditions and test specimens as applicable to ASTM procedures, and controlled laboratory conditions as required. 
• Applications: classification of materials, quality control in manufacturing, purchasing specifications, and laboratory evaluation and verification of polyethylene-film products.

What are the uses of ASTM D2103 testing? 

ASTM D2103 testing is used to determine the classification of polyethylene film and to see if measured characteristics match the type designation and specification requirements. This standard-

• Classifies polyethylene film using a five-digit type-number system. 
• Discusses range of densities for classification of polyethylene film. 
• Determines impact strength according to the applicable ASTM procedure. 
• Evaluates the kinetic coefficient of friction of the film. 
• Determines haze for applicable transparent or translucent film. 
• Checks nominal film thickness and relevant thickness characteristics. 
• Evaluates yield and applicable dimensional requirements. 
• Helps identify visible defects such as gels, streaks, pinholes, foreign particles, holes, tears, blisters, nicks, and cuts. 
• Assists in quality control and acceptance testing of polyethylene film.

Which Materials Can Be Tested Under ASTM D2103? 

ASTM D2103 is designed for polyethylene film in the thickness range for the applicable edition. D2103 includes polyethylene film up to 0.254 mm (0.010 in.) in thickness, inclusive. Films may contain additives for surface property improvement, pigments, or stabilizers.

Why is ASTM D2103 important? 

ASTM D2103 gives a systematic approach to the recognition of polyethylene film by physical measurement. This classification system is based on specified ranges of properties for density, impact strength, kinetic coefficient of friction, haze, and nominal thickness of the film instead of just the polymer type.

ASTM D2103 Testing Process and Data Collection 

The ASTM D2103 testing process starts with representative polyethylene-film sampling and identification of the applicable classification requirements. Technicians select properties for the type designation and prepare specimens using appropriate ASTM methods. The classification system includes five positions of properties: density, impact strength, kinetic coefficient of friction, haze, and nominal thickness. Each property is assigned a corresponding cell or range, and the resulting five-digit designation identifies the combination of characteristics represented by the film. Laboratories record raw measurements, calculated values, specimen identification, test conditions, equipment information, visual observations, and the resulting type designation. Results are then compared with the applicable requirements of ASTM D2103.

Common Challenges and Troubleshooting 

Accurate ASTM D2103 testing depends on representative sampling, correct specimen preparation, appropriate conditioning, and calibrated instruments. Test results can be affected by film thickness variation, orientation, contaminating surface, wrinkles, and improper specimen cutting. Analysts should inspect samples before testing, avoid damaged areas when the applicable procedure permits, maintain consistent specimen orientation and handling, and verify instrument calibration. If results do not correspond with the expected classification, personnel should review sample identification, conditioning, specimen preparation, measurement technique, and the applicable edition of ASTM D2103 before repeating the test.

• Laboratory-reported results may include density in g/cm³, impact strength in grams, kinetic coefficient of friction as a numerical ratio, haze in percent, and nominal thickness in mm. 
• Laboratories report the measured physical properties used to establish the applicable five-digit polyethylene-film classification. 
• Reports may include film identification, nominal thickness, production lot, surface treatment, visual condition, specimen orientation, and relevant test observations. 
• Technicians compare these results with the applicable type-number ranges, dimensional requirements, yield tolerances, and workmanship requirements.

What Factors Should You Consider for ASTM D2103 Testing? 

• Expertise: Testing should be performed by trained technicians, analysts, or plastic testing experts familiar with polyethylene-film characterization and the referenced ASTM methods. 
• Speed: Turnaround depends on the number of properties being evaluated, specimen conditioning, testing workload, and whether a complete classification is required. 
• Cost: Testing costs vary according to the number of physical properties, specimens, instruments, and referenced ASTM procedures included in the evaluation. 
• Confidentiality: Matestlab maintains complete confidentiality of client samples, analytical data, specifications, and test reports.
