# Sheet Garment Selection QA

> **Not medical advice.** Pre-wear checks are literacy, not allergy testing or device certification.
## Executive summary
Before wear or resale of a bought sheet garment, dipped-goods specs supply a borrowed vocabulary (holes, powder, protein, odor, bloom). Fashion sheet is not an ASTM D3578 exam glove.[^1] NIOSH separates irritant, delayed chemical, and immediate protein reaction patterns for workplace NRL products.[^2]
Use when buying secondhand sheet, inspecting a custom commission, or deciding first-wear go/no-go. Reaction classes: [Allergy and Skin Contact](/literature-reviews/allergy-and-skin-contact).

## Borrowed QC vocabulary
ASTM **D3578**: product standard for dipped NR examination gloves (holes, powder, protein, tensile).[^1] ASTM **D5151**: water-leak hole detection for medical gloves; smallest detectable hole is not determined by the method.[^3] Transfer to fashion sheet is analogy.

## Pre-wear checklist
1. **Light + stretch** for pinholes and thin spots.
2. **Powder / talc.** Medical powdered gloves banned as unreasonable risk.[^4] NIOSH workplace framing: powder can carry NRL allergens.[^2]
3. **Odor.** Reodorants mask curative / putrefaction / microbial odors at 0.25–0.5 phr; root cause preferred.[^5] Sniff ≠ protein assay.
4. **Bloom vs crack.** [Sheet Aging, Storage and Care](/literature-reviews/sheet-aging-storage-and-care).
5. **Stop.** New rash or breathing symptoms → stop wear; [Allergy and Skin Contact](/literature-reviews/allergy-and-skin-contact).
21 CFR **801.437**: NRL caution on medical devices; “hypoallergenic” forbidden on those devices.[^6]

Deep dive: Protein assay methods (glove lineage)
ASTM **D5712**: total aqueous extractable protein in NR products (µg/dm²); residual-protein testing, not wearer diagnosis.[^7]
ASTM **D6499**: immunological measurement of antigenic protein; not a measure of allergenic proteins; correlation not fully established.[^8]
ISO **12243**: assay method for water-extractable protein in NR medical gloves; not sampling, safety limits, or labelling.[^9]
Deep dive: What aged sheet looks like
Ambient ozone on the order of 1–8 pphm. Ozone cracks perpendicular to stress, usually widespread. Flex cracks: local, oriented, high-strain zone. UV cracks: non-oriented over the exposed area.[^10]
Inspection map: sticky tack (scission), hard/brittle (crosslink), chalky bloom (wax / antidegradant), oriented cracks (ozone / flex). Polish does not change ozone-crack morphology.
