What Is ASTM D2287 Non Rigid Vinyl Chloride Compound?
ASTM D2287, Standard Classification System and Basis for Specification for Nonrigid Vinyl Chloride Polymer and Copolymer Molding and Extrusion Compounds, is a classification and specification standard rather than a single test method. ASTM Committee D20 on Plastics, Subcommittee D20.15, maintains it. The current edition is D2287-26. Earlier editions such as D2287-19 now carry historical status, and older ones used the shorter title “Standard Specification for Nonrigid Vinyl Chloride Polymer and Copolymer Molding and Extrusion Compounds.” So what’s covered? Compounds whose resin portion contains at least 90 % vinyl chloride. The remaining portion may be monomers copolymerized with vinyl chloride, or other resins mechanically blended with polyvinyl chloride or its copolymers. A hardness range defines the compounds, and they contain the stabilizers, plasticizers, fillers, dyes and pigments needed to meet the stated requirements. They’re intended for compression molding, injection molding, and extrusion, although not every compound suits every process. The material itself should be uniform in composition. It’s ordinarily supplied diced or granulated. Instead of prescribing one procedure, D2287 uses a classification table to select and identify compounds by property requirements. Public summaries list the properties as durometer hardness, specific gravity, tensile strength, volatile loss, brittleness temperature, burning rate, and volume resistance. Each property is measured using its own referenced test method and compared against the requirements in the compound’s classification callout. The standard states that these properties are not necessarily suitable for direct design use, but they support inspection and quality control when performed as specified. SI units are the standard.
Applications and Benefits of ASTM D2287 Non Rigid Vinyl Chloride Compound Testing
Scope
This test determines the mechanical and physical performance characteristics of non-rigid vinyl chloride materials to ensure compliance with ASTM D2287 requirements and suitability for flexible applications.
- This is a classification system and basis for specification, not a standalone test method.
- It covers nonrigid vinyl chloride polymer and copolymer compound classes used for molding and extrusion.
- Each covered compound must have a resin portion containing at least 90 % vinyl chloride.
- Monomers copolymerized with vinyl chloride may make up part of the remaining resin portion.
- That remainder may also consist of other resins mechanically blended with polyvinyl chloride or its copolymers.
- Compounds are defined by a hardness range and include the additives needed to meet their requirements, such as stabilizers, plasticizers, fillers, dyes and pigments.
- Recommended processing routes are compression molding, injection molding and extrusion, though not every compound is suited to every method.
- Public summaries state that the material must be of uniform composition and is ordinarily supplied as diced or granulated compound.
- Recycled PVC may be used in some applications when it meets the requirements set by the relevant product standard.
- ISO 2898-1 and ISO 2898-2 address the same subject, but the standard notes that their technical content differs.
Applications
- Verifying that an incoming PVC compound lot matches the classification callout on a purchase order.
- Material specifications can reference a classification instead of a proprietary grade name.
- Incoming material inspection and routine quality control at molders and extruders.
- Candidates from different suppliers can be compared against the same classification requirements.
- Qualification files for products made from flexible PVC, such as wire insulation, tubing, and molded parts.
- Formulation changes are checked for their effect on hardness, tensile strength, and low-temperature behavior.
Benefits
- Buyers and suppliers share one classification language so that a compound can be described without ambiguity.
- Property requirements are tied to named tests. Any qualified laboratory can check conformance.
- Results support inspection and quality control, which is the use the standard itself describes.
- Lot-to-lot consistency problems show up early, before a compound reaches production.
- One report can cover several properties against a single classification callout.
- Using a current edition keeps specifications aligned with the standard, as ASTM D20.15 maintains it.
Our ASTM D2287 Testing Procedure
Sample Conditioning
Specimens are conditioned under controlled temperature and humidity to stabilize material properties before testing.
1Specimen Preparation
Standardized test samples are cut and prepared according to ASTM D2287 dimensional requirements.
2Mechanical Testing Execution
Tensile and elongation properties are measured using a universal testing machine under controlled loading conditions.
3Result Calculation & Evaluation
Measured values are analyzed and compared with specification limits for compliance determination.
4ASTM D2287 Test Parameters and Requirements
| Parameter | Details |
|---|---|
| Standard | ASTM D2287 for non-rigid vinyl chloride materials |
| Method | Uniaxial tensile testing for flexible PVC compounds |
| Measurement Type | Tensile strength and elongation behavior |
| Sample Type | Non-rigid PVC sheets, films, or molded specimens |
| Loading Type | Controlled tensile loading until failure |
| Units | MPa (strength), % elongation, N (force) |
- Durometer – Reads the indentation hardness of the molded compound, the property that defines the compound’s hardness range.
- Specific gravity balance or density apparatus – Determines the specific gravity of the compound specimen.
- Universal testing machine – Pulls tensile specimens to determine tensile strength.
- Forced-air oven and analytical balance – Together they support volatile loss measurements, tracking mass change after heating.
- Low-temperature brittleness apparatus – Finds the temperature at which the compound becomes brittle under impact.
- Burning rate test chamber – Holds specimens in a controlled flame test to rate burning behavior.
- Resistance measurement system – Measures the electrical volume resistance of conditioned specimens.

ASTM D2287 Non Rigid Vinyl Chloride Compound FAQs
ASTM D2287 evaluates mechanical properties of non-rigid vinyl chloride materials, particularly tensile strength and elongation. It ensures that flexible PVC products meet performance requirements for durability, flexibility, and structural integrity in various applications.
Tensile testing determines how the material behaves under stretching forces. It provides critical data on strength and flexibility, helping ensure the material can withstand mechanical stresses during use without failure.
Elongation at break indicates how much a material can stretch before failure. Higher elongation values reflect better flexibility and ductility, which are essential for applications requiring repeated bending or deformation.
Factors include plasticizer content, formulation, processing conditions, temperature, and aging. Variations in these parameters can significantly influence strength and flexibility characteristics.
Stress–strain curves provide detailed insight into material behavior under load, including elasticity, yield point, and failure characteristics, enabling comprehensive evaluation of performance.
