ASTM D2261-96 (2002) · 6.1-6.2

• Tongue tear uses a CRE tensile tester with force recording. Jaw faces at least 25 × 75 mm with the long dimension perpendicular to force; record specimen slip and jaw damage as invalidity flags.

ASTM D5034-95 · 6.1, 10.1.2

• Grab-test initial jaw spacing 75 ± 1 mm. Record 300 ± 10 mm/min fixed speed and 20 ± 3 s time-to-break as separate options; these differ from the 50 mm/min ISO 13934-2 recipe.

ASTM D5035-95 (2003) · 6.1-6.2.1

• Strip method uses 300 ± 10 mm/min or a selected constant time-to-break of 20 ± 3 s. Jaw face at least 10 mm wider than the specimen and at least 25 mm long in the force direction.

EN 14704-1:2005 / TS EN 14704-1:2006 · 6.1

• Elasticity CRE arrangement accommodates 20-500 mm/min within ±10% and gauge lengths 100-250 mm within ±1 mm. Force and jaw-separation error limits 1% and 1 mm respectively; record cycling between load or extension limits.

ASTM D2724-03 · 6.10

• For the tensile subtest of bonded/laminated apparel fabrics, clamp width is 76.2 mm and CRE is preferred. This edition prefers a 0–4.5 kgf indicating range. Record separation setup and force range; drycleaning and laundering are separate preparations.

ASTM D5587-03 · 6.1–6.2, 8.2–8.3

• For trapezoid tearing use CRE, initial jaw separation 25 ±1 mm and speed 300 ±10 mm/min. Gripping faces are at least 50 by 75 mm, long side perpendicular to force. Distinguish the 100 mm/min ISO nonwoven trapezoid setting.

ASTM D5822-03 · 6.1–6.2

• For inflatable-restraint seams use 300 ±10 mm/min or the selected 20 ±3 second time-to-break procedure; report the option. Front jaw width perpendicular to force is 25 ±1 mm, with 25–50 mm along force. CRE is preferred; record failure location.

ISO 11644:2022 · 5.1-5.5

• Leather-finish adhesion: jaw separation 100 ± 5 mm/min and force-distance recording. Use an adherent plate approximately 70 × 20 × 3 mm and a hook/clamp arrangement maintaining about 90° peel; general tensile grips alone are insufficient.

ISO 5081:1977 · 5.1.2-5.1.4

• Fabric tensile method: force indication error at most 1%, jaw-separation error at most 1 mm. Nominal gauge length 200 mm; 100 mm may be selected for fabrics with breaking elongation over 75%. Record machine type and selected gauge length.

ASTM D2212-00(2021) · 5.1–5.4, 6.1–6.2; required fixture figures not available locally

• 2021 edition: leather slit tear requires two special holders adjusted to touch. Die 1 × 2 in (25.4 × 51 mm); slot 7/16 × 3/16 in. Inch values govern. Missing figures/full text prevent holder-manufacturing or current-edition conformity verification.

BS 3424-5:1982 · 2.1.1, 2.4, 3.1, 3.4, 4.1; methods 7A/7B/7C

Control and recording specification

The following are method-specific software/recording requirements; delivered software modules are defined by the order scope.

• Method code and edition, specimen ID, operator and selected test parameters are linked to the record.
• Force-extension curve; strain = 100 × (L-L₀)/L₀; crosshead and extensometer results are identified separately.
• Raw measurements, units, valid/invalid test flags and the reported result remain traceable.
• Calculations are checked against known inputs and an independent calculation; sensor channels are checked against calibration values.
