The Rely Standard
Published,
not promised.
Most scrubs are sold on a feeling. Ours are sold on a threshold and the test that produced it — eight specifications every roll has to clear before it carries the Rely name.
/01Durability & Movement
Tears at no less than 15 newtons
ASTM D1424
A snag on a bed rail or a cart corner stretches the weave instead of opening a hole.
Grab tensile at no less than 350 newtons
ASTM D5034
Heavy lifting, sudden bending and deep squatting are the document’s own examples of what this fabric strength is built to withstand, without a seam splitting.
Grade 4.0 minimum for pilling after abrasion
ASTM D4970
The surface stays smooth where a badge reel, a stethoscope or a seat belt rubs it every shift.
/02Industrial Laundering & Colour Vitality
Holds its fit to within ±2.5% after washing
AATCC TM135
On a 32-inch inseam that is about three quarters of an inch — enough to notice, which is why the figure is printed rather than called zero.
Grade 4.0 colourfastness to industrial laundering
AATCC TM61
Grade 4.0 on a five-point scale is strong, not absolute: the colour holds its depth through repeated hot washes.
Grade 3.5 wet crocking, so transfer is slight rather than absent
AATCC TM8 / TM188
Grade 3.5 permits slight transfer by definition, so a wet navy sleeve against a white coat is stated, not denied.
/03Shift-Long Comfort
160–180 GSM: opaque without weight
ASTM D3776
Heavy enough not to show what is underneath, light enough that a twelve-hour shift does not feel like one.
One-way transport index above 100
AATCC TM195
TM195 measures how strongly moisture moves from the skin side to the outer face. It is a transport figure, not a drying time.
