D4116-20 – Standard Test Method Technical Guide
The ASTM D4116-20 standard provides performance specifications for knitted and woven fabrics used in women’s and girls’ corsets, girdles, and combination garments. It applies to fabrics composed of any textile fiber or mixture of fibers, excluding knitted lace and interlining fabrics. Requirements are applicable to both length and width directions where pertinent.
📜 Scope and Applicability
This performance specification covers woven and knitted fabrics for corsets, girdles, or combination garments. It is not applicable to knitted lace fabrics or interlinings. The standard addresses safety, health, and environmental practices but does not purport to address all safety concerns.
⚙️ Referenced Test Methods and Requirements
The standard references various ASTM and AATCC test methods for evaluating fabric performance. These methods are used to determine compliance with the specification.
| 🟦 Test Method | 📐 Property Measured |
|---|---|
| D5034 | Breaking Strength and Elongation |
| D3786 | Bursting Strength (Diaphragm) |
| D3787 | Bursting Strength (Ball Burst) |
| D2261 | Tearing Strength (Tongue) |
| D434 | Resistance to Yarn Slippage (Withdrawn) |
| AATCC TM8 | Colorfastness to Crocking |
| AATCC TM15 | Colorfastness to Perspiration |
| AATCC TM135 | Dimensional Changes After Laundering |
📊 Key Measured Properties and Compliance
Compliance involves ensuring fabrics meet specified performance levels in strength, colorfastness, and dimensional stability. The standard also incorporates federal flammability regulations under 16 CFR 1610. Specific requirements are determined through the referenced test methods, with evaluation in both fabric directions.
| ⚡ Property | 🎯 Test Method |
|---|---|
| Colorfastness to Light | AATCC TM16.3 |
| Colorfastness to Laundering | AATCC TM61 |
| Colorfastness to Burnt Gas Fumes | AATCC TM23 |
| Colorfastness to Bleach (Non-Chlorine) | AATCC TM172 |
| Colorfastness to Bleach (Chlorine) | AATCC TM188 |
| Colorfastness to Crocking (Rotary) | AATCC TM116 |
💡 Tip: Always refer to the latest versions of referenced standards like AATCC TM16.3 and ASTM D5034 to ensure current compliance. Note that historical methods like D434 have been withdrawn but are referenced for context.
⚠️ Warning: This standard does not address all safety concerns. It is the user’s responsibility to establish appropriate safety, health, and environmental practices and determine regulatory limitations prior to use.
