ASTM D2654-22 PDF

Full title and description

ASTM D2654-22 — Standard Test Methods for Moisture in Textiles. This document specifies four test procedures for measuring moisture content, moisture pick-up, moisture equilibrium, and moisture regain in textile fibres and textile products; it covers oven-drying techniques (ambient and standard atmosphere), equilibrium methods, and a procedure intended for research/standard moisture-regain determinations.

Abstract

These test methods describe accepted laboratory procedures to determine moisture present in textile materials (natural and man-made, from fibre or filament to finished fabric). Procedures include simple oven-drying using ambient air, oven-drying using air from the standard textile atmosphere, moisture-equilibrium methods, and a research-level procedure for moisture regain. The standard explains significance, limitations, and recommended use of each procedure for process control, commercial acceptance testing, and research.

Scope

The standard covers measurement of moisture in textile materials as (1) moisture content or pick‑up using ambient air for oven‑drying, (2) moisture content or pick‑up using the standard atmosphere for testing textiles for oven‑drying, (3) moisture content or pick‑up at moisture equilibrium, and (4) moisture regain. It applies to natural and man‑made fibres and their processed forms, including blends, subject to stated limitations and exceptions (for example, materials containing significant nonaqueous volatile matter).

Key topics and requirements

• Definitions and terms related to moisture content, moisture pick‑up, and moisture regain.
• Procedure 1 — Oven‑drying using ambient air (quick, convenient for process control; not recommended for certain materials or for commercial acceptance).
• Procedure 2 — Oven‑drying using air from the standard textile atmosphere (recommended basis for commercial transactions when non‑aqueous volatiles are negligible).
• Procedure 3 — Oven‑drying under specified equilibrium conditions (used to determine moisture in equilibrium states, not generally for acceptance testing).
• Procedure 4 — Research technique for determining standard moisture regain (intended for R&D and establishing standard regain values; care needed due to potential bias between producer and buyer data).
• Instructions on specimen handling, conditioning, corrections for sampling, and statistical handling when comparing inter‑laboratory results (bias investigation guidance).
• Notes on limitations: avoidance of oven‑drying where significant non‑aqueous volatile matter is present (toluene‑distillation methods referenced for such cases).

Typical use and users

Used by textile testing laboratories, quality control and process engineers in textile manufacturing, procurement and trade organizations (for acceptance testing and disputes), materials researchers, and standards/compliance specialists. Typical applications include incoming inspection, production process control, commercial mass adjustments, blend verification, and R&D studies of moisture‑related properties.

FAQ

Q: What is this standard?

A: ASTM D2654-22 is a set of standard test methods for measuring moisture in textile materials (moisture content, pick‑up, equilibrium moisture, and moisture regain), published by ASTM International in 2022.

Q: What does it cover?

A: It covers four procedures (two oven‑drying methods, an equilibrium method, and a research regain procedure), specimen conditioning and handling, calculation methods, and guidance on appropriate use and limitations (for example, when non‑aqueous volatiles require alternative methods).

Q: Who typically uses it?

A: Textile manufacturers and converters, materials testing labs, quality/control personnel, procurement/trade parties involved in acceptance testing, and researchers studying moisture effects in textile materials.

Q: Is it current or superseded?

A: The 2022 revision (D2654-22) is the current ASTM designation; the ASTM publication record lists the standard as active and shows maintenance activity (ASTM’s product page indicates the document is active and maintained). Users should check ASTM’s catalog for any amendments or later revisions after 2022.

Q: Is it part of a series?

A: Yes — it is part of ASTM Committee D13 (Textiles) test methods collection (Book of Standards volume for textiles), and it cross‑references other D13 methods for related moisture and conditioning procedures.

Q: What are the key keywords?

A: Moisture content, moisture regain, oven‑drying, standard atmosphere, textile testing, conditioning, fibres, equilibrium.
