D3783-02 – Standard Test Method Technical Guide
ASTM D3783-02 establishes the minimum performance criteria for woven flat lining fabrics intended for use in men’s and boys’ apparel. This specification covers linings composed of any textile fiber or fiber blend, providing manufacturers, retailers, and quality assurance labs with a standardized benchmark for evaluating durability, colorfastness, dimensional stability, and safety. The standard is under the jurisdiction of ASTM Committee D13 on Textiles and is the direct responsibility of Subcommittee D13.61 on Apparel.
📐 Scope and Referenced Standards
As defined in Section 1, this performance specification explicitly covers woven flat lining fabrics and excludes specialized constructions. According to Section 1.3, all requirements apply to both the warp (lengthwise) and filling (widthwise) directions. The standard relies on a rigorous set of ASTM and AATCC test methods to ensure comprehensive evaluation.
| ⚡ Category | 📏 Referenced Standard | 🎯 Purpose / Property Evaluated |
|---|---|---|
| Mechanical Properties | ASTM D5034, D1424, D2261, D434, D1336 | Breaking strength (grab test), tear resistance (Elmendorf/tongue), seam slippage, and yarn distortion |
| Colorfastness & Care | AATCC 8, 15, 16, 23, 61, 116, 132, 172, 188 | Resistance to crocking, perspiration, light, burnt gas fumes, laundering, drycleaning, and bleach |
| Dimensional Stability & Appearance | AATCC 96, 124, 135; ASTM D2724 | Shrinkage, durable press appearance after laundering, and evaluation of bonded/fused components |
| Regulatory & Sampling | 16 CFR 1610; MIL-STD-105D; ASTM D2905 | Flammability compliance (Clothing Textiles Standard) and statistically significant sampling plans |
⚠️ Exclusion Notice: Per Section 1.2, this standard is not applicable to woven pile, woven fusible, fire-bonded fusible, sliver-knit pile, or sheepskin lining fabrics. These constructions require evaluation under alternative performance specifications.
⚙️ Key Performance Criteria and Test Methods
Testing must be performed under standard atmospheric conditions for textiles (21 ± 1 °C, 65 ± 2% RH) using the specific test methods cited in Section 2. The standard heavily relies on AATCC Evaluation Procedure 1 (Gray Scale for Color Change), Evaluation Procedure 2 (Gray Scale for Staining), and Evaluation Procedure 3 (AATCC Chromatic Transference Scale) for quantifying colorfastness results.
| 🟦 Property | 📏 Test Method | 🎯 Minimum Performance Requirement |
|---|---|---|
| Breaking Force (Grab) | ASTM D5034 | Warp: 178 N (40 lbf) / Filling: 133 N (30 lbf) |
| Tearing Strength (Elmendorf) | ASTM D1424 | Warp: 4.4 N (1.0 lbf) / Filling: 3.5 N (0.8 lbf) |
| Resistance to Yarn Slippage | ASTM D434 | Max 3.2 mm (⅛ in) slippage at 111 N (25 lbf) |
| Colorfastness to Crocking | AATCC 8 / AATCC 116 | Dry: Class 4 (min) / Wet: Class 3 (min) |
| Dimensional Change (Laundering) | AATCC 135 | ± 3.0 % maximum (Warp & Filling) |
| Colorfastness to Perspiration | AATCC 15 | Shade Change: Class 4 / Staining: Class 3 (min) |
💡 Procedure Note for Tear Strength: The standard permits the use of either the Falling-Pendulum (Elmendorf) Apparatus per D1424 or the Tongue (Single-Rip) Method per D2261 (CRE) or D2262 (CRT). Ensure the selected method is agreed upon between the purchaser and the supplier prior to evaluation.
📊 Sampling and Safety Compliance
Sampling procedures are governed by Military Standard MIL-STD-105D (Sampling Procedures and Tables for Inspection by Attributes) or an equivalent statistical plan as agreed upon by contractual parties. The specific number of test specimens required for each property should follow the guidelines established in Practice ASTM D2905.
All lining fabrics must meet the applicable flammability requirements. Section 2.3 of the standard explicitly references 16 CFR Part 1610 (Standard for the Flammability of Clothing Textiles) and the associated Flammable Fabrics Act Regulations in 16 CFR Chapter II.
