D5219-15 – Standard Test Method Technical Guide
📐 Standard Overview and Scope
ASTM D5219-15 is a standard terminology compilation for body dimensions used in apparel sizing. Published under ASTM International, it provides definitions for key anatomical landmarks with “height” for vertical measurements and “length” for contour measurements. This standard is a primary reference for the apparel industry to ensure consistent sizing terminology. The standard references ASTM D123 for general textile terminology and ISO 3635 and ISO 8559 for body measurement procedures. Terms are listed alphabetically and illustrated with three-dimensional avatars from Alvanon Inc. in Figures 1-19.
🧍 Key Anatomical Landmarks
The following table summarizes important body landmarks defined in the standard, which are essential for accurate apparel sizing.
| 🟦 Term | 📐 Definition | 🎯 Figure |
|---|---|---|
| Acromion | Part of shoulder blade at end of spine articulating with collarbone | Fig. 2 |
| Cervicale | Prominent point of seventh neck vertebra at back of torso | Fig. 2 |
| Crotch | Lowest point of torso where legs separate | Fig. 1 |
| Waist | Torso part between lowest rib and hip, identified by side bending | Fig. 1 |
| Preferred Waist | Waist as identified by wearer for bottom garments | Fig. 1 |
| Shoulder Joint | Juncture of collarbone and shoulder blade | Fig. 2 |
| Apex | Greatest protrusion of the breast as seen from the side | Not specified |
📏 Measurement Designations
In this standard, “height” is exclusively used for vertical measurements, such as cervicale height, which is taken with the head erect. “Length” is designated for contour measurements, like body curves. This distinction prevents ambiguity in garment pattern creation. The term “preferred waist” is also defined, noting it is the waist as identified by the wearer for bottom garments, which may differ from the anatomical waist.
💡 Tip: For cervicale height measurement, ensure the subject’s head is erect. Although the cervicale is more prominent when the head is bent forward, all standard measurements require an erect head position.
⚠️ Important: The shoulder joint discussion highlights that the outer end of the collarbone pivots against the acromion, which in turn pivots against the humerus, forming the shoulder girdle. This is crucial for arm movement in garment design.
