ASTM F2524-06 (2020) PDF

Full title and description

Standard Practice for Determination of Volatile Content for Formed-in-Place Gaskets (FIPG) Silicone Adhesives and Sealants for Transportation Applications — designation F2524‑06 (reapproved 2020). This short practice describes a laboratory procedure to quantify the volatile matter evolved during curing of FIPG silicone adhesives and sealants used in transportation applications.

Abstract

This practice provides a quantitative test method to determine the amount of volatile components released by formed‑in‑place gasket (FIPG) silicone adhesives and sealants during cure. The method establishes the volatile content (curing by‑product mass evolved) but does not identify the chemical species. It is intended for use in transportation industry quality control and materials evaluation.

Scope

This practice covers the quantitative determination of volatile matter evolved during cure of silicone adhesives and sealants applied as formed‑in‑place gaskets (FIPG) for transportation applications. It specifies required apparatus and general test conditions (humidity/temperature controlled oven or humidity chamber with forced ventilation), describes sample preparation and measurement principles, and notes that the test quantifies total volatile content but does not provide component identification.

Key topics and requirements

• Purpose: quantify volatiles/by‑products released during curing of FIPG silicones for transportation use.
• Apparatus: humidity chamber or temperature‑controlled forced‑ventilation oven (type consistent with ASTM E145 requirements), controlled temperature (typical reference 40 ±1 °C) and humidity control.
• Terminology and definitions for FIPG by‑products and volatile content.
• Procedure summary: expose cured samples under specified conditions and determine evolved volatile mass (gravimetric or appropriate capture/measurement), with limits on identification (method does not speciate chemical components).
• Referenced standards and test methods: includes related ASTM procedures for humidity measurement and oven specifications (examples cited in the practice).

Typical use and users

Used by materials and product engineers, adhesive/sealant manufacturers, OEMs in the transportation sector (automotive, rail, aerospace ground equipment), and independent testing laboratories for quality control, material comparison, and verification that FIPG silicone formulations meet volatile‑release expectations for application environments.

Related standards

References and related documents cited in the practice include ASTM standards relevant to humidity measurement and oven specifications (for example, ASTM D4230 and ASTM E145 are referenced within the practice), and other ASTM methods/guides for silicone volatiles and gasket testing used in transportation applications. Users should consult the practice for the full list of referenced documents.

FAQ

Q: What is this standard?

A: It is ASTM F2524‑06 (reapproved 2020), a short practice for determining the volatile content evolved during cure of formed‑in‑place gasket (FIPG) silicone adhesives and sealants used in transportation applications.

Q: What does it cover?

A: It covers a quantitative laboratory procedure to measure total volatile matter released during curing (test apparatus requirements, environmental control, terminology and measurement approach). It does not identify individual chemical species within the volatiles.

Q: Who typically uses it?

A: Materials engineers, adhesive/sealant manufacturers, OEM quality teams, and third‑party testing labs in the transportation sector use this practice for product evaluation and quality control.

Q: Is it current or superseded?

A: The practice was originally approved in 2006 and is shown as reapproved in 2020 (F2524‑06R20). Consult ASTM International for any later reapproval or revision notices beyond the 2020 reapproval.

Q: Is it part of a series?

A: It is maintained under ASTM Committee F03 (Gaskets) and Subcommittee F03.50 (Analytical Test Methods). It is one of several ASTM practices and test methods addressing gasket materials, silicone volatiles, and related adhesive/sealant testing for transportation applications.
