“AATCC 117 is a standardized test method used to evaluate colour fastness to dry heat or sublimation in synthetic textiles.”

AATCC TM117 is titled "Test Method for Colorfastness to Heat: Dry (Excluding Pressing)" and covers dry heat, so the dry-heat half of the claim holds, but the AATCC store page scopes it to "textiles of all kinds and in all forms," not to synthetic textiles, and it excludes pressing. AATCC's own store listing is the better authority over vendor marketing, since it reproduces the method's Purpose and Scope; nothing on either page uses the word "sublimation" or supports the vendor label "AATCC 117 Color Fastness to Sublimation," and the vendor page itself was not on the page as a source text.
