DO THESE MEET ASTM F887?

Sorry for delay in response. This is direct from Distel the manufacturer.

"From our perspective the ASTM standard for climbing spurs is mainly a standard that was tailored to the US design of spurs, like Bashlin or Buckingham.

We test of course all our climbers to the important load test “7.6.1.1 Deformation test” and the important cycle test “7.6.1.2 Fatigue test” for the shank.

We pass the “7.6.1.1 Deformation test” (static load of 750 lbf for three minutes) with all our climbers.

The “7.6.1.2 Fatigue test” (cycle load test with 100.000 cycles) is exceeded by passing 100.000 cycles with a load of 390 lbf for the Alu 3 model instead of the required 300 lbf.

Points which are not fulfilled by our climbers are mostly of design nature:

7.1.2 Types B and C shall be available with the size adjustment capability of 14¾ to 21 in. (374.7 to 533.4 mm) by
increments of ¼ in. (6.4 mm).

The climbers are only adjustable up to a length of 47,8 cm.

8.2 Material--All gaffs shall be forged of forging-quality
steel having the properties listed in Table 2.

The gaffs of the pole climbers are made out of steel by precision casting and not forged. So they do not meet point 8.2.

However, the gaffs of the tree climbers are forged ones. All our gaffs are crack-tested by a test institute after hardening.

We do not meet the required gaff angle for the pole gaffs."
