Описание (английский):

The density of an unplasticised polyvinylchloride (PVC-U) pipe or -fitting, measured by the method described in ISO 1183, shall be between the limits of 1,35 gram per cubic centrimetre and 1,46 gram per cubic centrimetre. This does not apply to pipes made of compounds containing fillers or cellular products.

Overview

ISO 4439:1979 establishes the requirements for determining and specifying the density of unplasticized polyvinyl chloride (PVC-U) pipes and fittings. Developed by ISO, this international standard supports manufacturers and quality assurance teams in verifying product conformity through standardized density measurements. The standard references ISO 1183 for testing methodology and defines acceptable density ranges, promoting uniformity in material quality across the PVC-U piping industry.

Key Topics

Density Range Specification

The density of unplasticized polyvinyl chloride (PVC-U) pipes and fittings must fall between 1.35 g/cm³ and 1.46 g/cm³.

Exclusions

The specified limits do not apply to pipes or fittings made with added fillers or cellular PVC compounds.

Testing Method

Density measurement must be performed using the procedure outlined in ISO 1183, ensuring reproducible and reliable results.

Material Characterization

Consistent density determination supports assessment of raw material quality and product performance in practical applications.

Applications

The guidelines in ISO 4439:1979 are crucial in various sectors that manufacture, test, or utilize PVC-U pipes and fittings:

Manufacturing Quality Control

Ensures that unplasticized PVC products conform to specified density requirements before distribution.

Product Certification and Compliance

Supports regulatory and industry compliance for plumbing, water supply, and industrial piping applications.

Material Selection

Assists engineers in sourcing PVC-U materials with reliable density characteristics, improving system safety and longevity.

Research and Development

Provides a standardized benchmark for developing new PVC-U formulations without fillers, ensuring consistency during innovation.

Related Standards

Those working with PVC-U pipes and fittings or involved in plastic material testing may also find these standards relevant:

ISO 1183 – Plastics – Methods for determining the density of non-cellular plastics

ISO 4422 – Unplasticized polyvinyl chloride (PVC-U) pipes for water supply – Specifications

ISO 1452 – Plastics piping systems for water supply and for buried and above-ground drainage and sewerage under pressure – Unplasticized poly(vinyl chloride) (PVC-U)

ISO 161 – Thermoplastics pipes for the conveyance of fluids – Nominal outside diameters and nominal pressures

Practical Value

By adhering to ISO 4439:1979, companies and laboratories benefit from:

Standardized material assessment for global trade and supply chain consistency

Enhanced product reliability by maintaining density within the specified range

Efficient quality assurance using universally accepted test methods

Improved market acceptance due to compliance with recognized ISO standards

Implementing this standard ensures that unplasticized PVC pipes and fittings meet the essential density requirements for optimal mechanical performance and long-term durability in diverse industrial and construction environments.
