ISO 1060-1-1998 PDF

Full title and description

ISO 1060-1:1998 — Plastics — Homopolymer and copolymer resins of vinyl chloride — Part 1: Designation system and basis for specifications. This part defines a system for designating vinyl chloride thermoplastic resins to be used as the basis for specifications and identification of resin types.

Abstract

Part 1 of ISO 1060 established a designation/classification system for vinyl chloride (PVC) homopolymers and copolymers based on designatory properties (for example reduced viscosity, apparent density, sieve retention, plasticizer absorption and paste rheology) and on information about polymer parameters, polymerization processes and intended applications. The document was limited to powdered resins and was intended as a basis for specifications rather than a source of processing or engineering performance data.

Scope

ISO 1060-1:1998 applied to powdered homopolymers and copolymers where vinyl chloride is the main constituent. It specified a designation and classification system based on measurable designatory properties to allow consistent specification and communication of resin types. It did not provide engineering or processing performance data; where additional property determinations were required, reference test methods (see Part 2) were to be used. The Part 1 content has since been superseded and incorporated into the ISO 24024 series.

Key topics and requirements

• Designation system for PVC resins (naming and data-block structure used to record essential resin characteristics).
• Classification by designatory properties: reduced viscosity; apparent (bulk) density; retention on a 63 μm mesh sieve; plasticizer absorption at room temperature (for general‑purpose resins); and paste viscosity/rheological behaviour (for paste resins).
• Inclusion of background information such as basic polymer parameters, polymerization process and intended applications to aid correct specification.
• No provision of processing or engineering performance data — users must specify additional properties or use Part 2 test methods where needed.

Typical use and users

Used by resin producers, materials engineers, specifiers, quality control laboratories and purchasers of PVC powders to designate and communicate the key properties of vinyl chloride resins when preparing specifications, procurement documents and conformity checks. Because the 1998 edition is withdrawn, users should consult the 2021 ISO 24024 series for current designation and testing practices.

Related standards

ISO 1060-2:1998 (Part 2: Preparation of test samples and determination of properties) provided the companion test methods and has also been withdrawn and superseded. Both Part 1 and Part 2 of ISO 1060 were revised and replaced by the ISO 24024 series (ISO 24024-1:2021 and ISO 24024-2:2021), which contain the current designation system and the corresponding test/sample-preparation methods. Other regional/adopted versions (EN/ national adoptions) mirror these ISO publications.

FAQ

Q: What is this standard?

A: ISO 1060-1:1998 is the International Standard that defined a designation system and the basis for specifications of homopolymer and copolymer resins of vinyl chloride (PVC) in powdered form.

Q: What does it cover?

A: It covered a classification and designation scheme based on key measurable resin properties (reduced viscosity, apparent density, 63 μm sieve retention, plasticizer absorption for general-purpose types, and paste viscosity/rheology for paste resins) and provided the data-block concept for specification. It did not provide processing or performance engineering data.

Q: Who typically uses it?

A: Resin manufacturers, product specification writers, procurement teams, materials laboratories and standards/quality engineers involved with PVC resin specification, selection and testing.

Q: Is it current or superseded?

A: ISO 1060-1:1998 is withdrawn. It has been superseded by ISO 24024-1:2021 (Part 1) and related Part 2 (ISO 24024-2:2021) which provide the current designation system and test/sample-preparation methods. Users should reference the ISO 24024 series for up-to-date requirements.

Q: Is it part of a series?

A: Yes — it was Part 1 of the ISO 1060 series. Part 2 covered preparation of test samples and determination of properties. The series has been reissued under the ISO 24024 designation (Parts 1 and 2) in 2021.

Q: What are the key keywords?

A: PVC, vinyl chloride, resin designation, resin classification, reduced viscosity, bulk/apparent density, sieve retention, plasticizer absorption, paste rheology, ISO 1060, ISO 24024.
