Full title and description

St ISO 14528-2-1999 — Plastics — Melamine-formaldehyde powder moulding compounds (MF‑PMCs) — Part 2: Preparation of test specimens and determination of properties. This part of ISO 14528 specifies procedures for handling and conditioning powder moulding compounds, the preparation of compression‑ or injection‑moulded test specimens and the test methods used to determine the physical and mechanical properties needed to characterise MF‑PMCs.

Abstract

This standard defines the recommended methods to prepare test specimens from melamine‑formaldehyde powder moulding compounds and the test procedures and conditions for measuring their properties. It gives requirements for material handling and conditioning, identifies specimen dimensions and describes test methods (many selected from ISO 10350‑1) that are suitable and necessary for reproducible and comparable characterisation of MF‑PMCs.

Scope

ISO 14528‑2:1999 applies to powder moulding compounds based on melamine‑formaldehyde and specifies the preparation of test specimens (including recommended moulding and conditioning procedures), and test methods used to determine properties required for material characterisation and specification. It complements ISO 14528‑1 (designation and specification basis) and selects and adapts general test methods (for example from ISO 10350‑1) that are appropriate for MF‑PMCs to ensure reproducible and comparable results.

Key topics and requirements

• Requirements for handling powder moulding compounds prior to moulding (sampling, storage, pre‑conditioning).
• Specified procedures and conditions for preparing compression‑ and injection‑moulded test specimens (moulding parameters, specimen dimensions and conditioning before testing).
• Test methods for physical and mechanical properties selected as appropriate for MF‑PMCs (tensile, flexural, hardness, density, thermal and other relevant tests, with references to ISO 10350‑1 where applicable).
• Criteria and practices to achieve reproducible and comparable test results across laboratories (controlled specimen preparation, conditioning and test conditions).
• Relationship to the designation and designatory properties defined in ISO 14528‑1 and to requirements for specified compound types (see ISO 14528‑3).

Typical use and users

Used by materials laboratories, manufacturers of melamine‑formaldehyde powder moulding compounds, product and quality engineers, test houses and standards committees. Typical applications include quality control of incoming batches, material specification for component design, comparative material characterization during product development and certification testing.

Related standards

Part of the ISO 14528 series: ISO 14528‑1:1999 (designation system and basis for specifications) and ISO 14528‑3:1999 (requirements for selected moulding compounds). It also references general test methods such as those in ISO 10350‑1 and replaces/updates earlier related documents in the thermosetting materials area (historically ISO 2112:1990 is noted in the standard's lifecycle). Several national and regional bodies have adopted EN/ISO versions (for example EN ISO/ÖNORM adoptions).

FAQ

Q: What is this standard?

A: ISO 14528‑2:1999 is an International Standard that specifies how to prepare test specimens from melamine‑formaldehyde powder moulding compounds and which test methods and conditions to use when determining their properties.

Q: What does it cover?

A: It covers handling and conditioning of the powder material, moulding of test specimens (compression or injection), specified specimen dimensions and conditioning prior to testing, and the test methods suitable for characterising MF‑PMCs (many methods referenced from ISO 10350‑1).

Q: Who typically uses it?

A: Material producers, product designers, test laboratories, quality control personnel and standards bodies involved with thermosetting moulding compounds and components manufactured from MF‑PMCs.

Q: Is it current or superseded?

A: ISO 14528‑2 was published in 1999. The ISO entry indicates the document has been periodically reviewed and the published 1999 edition remained the current/confirmed version at the time of the latest systematic review. Users should check their national standards body or ISO publication records for any subsequent amendments or replacements before relying on the standard for regulatory or contractual purposes.

Q: Is it part of a series?

A: Yes — it is Part 2 of the ISO 14528 series. Part 1 defines the designation system and basis for specifications (ISO 14528‑1:1999) and Part 3 specifies requirements for selected moulding compounds (ISO 14528‑3:1999).

Q: What are the key keywords?

A: Melamine‑formaldehyde, powder moulding compound, MF‑PMC, thermoset, specimen preparation, conditioning, mechanical tests, ISO 14528.
