- Buried plastic pipe under external load, the diameter of the vertical diameter deformation rate should be less than the allowable diameter of the pipe deformation rate The diameter of the allowable diameter of the pipe shall not be greater than 5% The diameter deformation rate of the pipe and the allowable diameter deformation rate are calculated as follows: ε ΔD / D0 × 100% [ε] ε0 / K where: εΔD pipe in the combined load (Mm) [ε] Permissible diameter Deformation rate ε0 Elastic diameter Deformation rate (%) of pipe, by the flattening of the diameter of the pipe diameter (mm) The test determines the K safety factor, generally desirable 15s

- This test with a small sample length 127mm, width 12.7mm, the maximum thickness of 3.2mm. In the absence of ventilation test chamber. The top of the specimen (6.4 mm place) is clamped with a clamp on the bracket and the longitudinal axis of the specimen is kept vertical. The lower end of the specimen is 9.5mm from the lamp tip and 305mm from the dry absorbent cotton surface. Bring the Bunsen burner and adjust it to produce a blue flame with a height of 19mm. Place the Bunsen Lights flame at the bottom of the sample for 10s, then remove the flame (at least 152mm away from the specimen) and write down the sample. Burning time. If the flame of the sample within 30s after removal of the flame is extinguished, the original lamp must be moved under the specimen again, re-ignite the sample for 10s, and then remove the Bunsen burner again and note the flame burning And flames burning the burning time. If the sample droplets drip, let it fall into the sample under the 305mm cotton, to see whether it ignited cotton. If the absorbent cotton is on fire, the rating should be taken into account. Specific grading indicators are as follows. Test Item 94V-094V-194V-21 Ten-time ignition Total flame burning time Maximum value (S) Individual flame burning time Maximum value (s) Flameless burning time (s) Yes Flame drop No No Allow only short time Burning general UL yellow card on the thickness of the test strip is divided into: 1/8 inch, 1/16 inch, 1/32 inch thickness, that is, 3.2mm, 1.6mm, 0.8mm three grades test.s
