The choice between desiccant and water, and the quality of the seal, decide whether the number means anything.https://www.texlabinstruments.com/blog/which-flammability-standard-applieshttps://www.texlabinstruments.com/blog/which-flammability-standard-appliesWed, 26 Aug 2026 09:00:00 +0300Vertical, horizontal, 45°, NFPA 701, UL 94 — the geometry of the test is chosen by the end use, not by preference. A guide to picking the right one before you build the lab.https://www.texlabinstruments.com/blog/three-water-tests-three-questionshttps://www.texlabinstruments.com/blog/three-water-tests-three-questionsWed, 26 Aug 2026 09:00:00 +0300Hydrostatic head, spray rating and Bundesmann measure completely different things. Specifying the wrong one is how a "waterproof" fabric ends up soaking through in the field.https://www.texlabinstruments.com/blog/strip-versus-grab-tensile-testhttps://www.texlabinstruments.com/blog/strip-versus-grab-tensile-testWed, 26 Aug 2026 09:00:00 +0300ISO 13934-1 and ISO 13934-2 measure the same property with different specimen geometry — and the grab method reliably reports higher numbers. Here is why, and when each one is correct.https://www.texlabinstruments.com/blog/iso-139-conditioning-before-the-testhttps://www.texlabinstruments.com/blog/iso-139-conditioning-before-the-testWed, 26 Aug 2026 09:00:00 +0300Conditioning is the step most laboratories treat as optional and most disputes trace back to. What the standard atmosphere actually requires, and why approaching it from the dry side matters.https://www.texlabinstruments.com/blog/iso-12947-martindale-abrasion-end-pointhttps://www.texlabinstruments.com/blog/iso-12947-martindale-abrasion-end-pointWed, 26 Aug 2026 09:00:00 +0300ISO 12947 has four parts and three different end points. Choosing the wrong one is the most common reason two labs report different abrasion cycles for the same fabric.https://www.texlabinstruments.com/blog/crockmeter-rubbing-fastness-errorshttps://www.texlabinstruments.com/blog/crockmeter-rubbing-fastness-errorsWed, 26 Aug 2026 09:00:00 +0300ISO 105-X12 looks like the simplest test in the laboratory. It is also one of the easiest to run wrong — usually in the rubbing cloth, not the instrument.https://www.texlabinstruments.com/blog/iso-12945-2-martindale-pillinghttps://www.texlabinstruments.com/blog/iso-12945-2-martindale-pillingTue, 25 Aug 2026 09:00:00 +0300Five details in the Martindale pilling method that quietly change your grade — and how to control each one so your results match your customer's lab.
