Product description

SURELINK 7Way with 14/10mm Microduct

A	Sheathing Raw Material Test:
1.	Density	0.940 – 0.955g/cc
2.	Melt Flow Index	0.54grams/10 minutes
B	Test on Future path Duct
1.	Workmanship	External sheath black in color and be free from visual defects like blisters, shrink holes, flaking, scratches, groove lines and roughness.
2.	Sheath Thickness(T)	Outside Diameter : 10mm +/-0.3mm
3.	Minimum Bending Diameter	1000mm
4.	Crush Performance	Duct shall not damage when 1150 Newton load applied for 60 seconds. Residual deformation shall not exceed 15% when checked after 1 hour of removing load.
5.	Bending Performance	There shall be no damage when mounted on a mandrel of 1000mm diameter for 30 minutes. A ball of 7.0mm passes freely.
6.	Elongation	Elongation should not exceed 2.5% when tensile load 3960N is applied.
7.	Pulling Strength	The elongation is 10% at maximum working pull strength of 1650N.
8.	Pre-placement Compression Test	No damaged or permanent reduction of the original OD>4% when compressive load of 1320N is applied for one minute at installation temperature of 50+/-2⁰C.
9.	Post- placement Compression Test	No damaged or permanent reduction of the original OD>4% when 880N load is applied for one minute after releasing the tensile load of 3960N at temperature of 23+/-5⁰C.
10.	Impact Test	No evidence of cracks or tears when subjected to an impact of 136J at 20⁰C+/-2⁰C after conditioning for minimum 5 hours.
11.	Bending Test	The sample should not show any buckling, kinking or permanent ovalization when bent 180 degrees at 1000mm mandrel and then straightened after conditioning the sample at temperature -20⁰C+/-2⁰C for 4 hours.
C	Test for Micro Ducts: Raw Material Test:
1.	Density	0.940 – 0.955 g/cc
2.	Melt Flow Index	0.54grams/10 minutes
D	Test on 14/10mm Micro Duct
1.	Workmanship	Both layers of conduit shall be homogeneous throughout and essentially uniform in color, capacity, density and other properties. The inside and outside surfaces shall be free from visible cracks, holes, blisters, voids, foreign inclusions or other deleterious defects.
2.	Dimensions & Tolerances Outside Diameter Average Wall Thickness	14mm +/-0.1mm 2.0mm +/-0.1mm

3.	Toe-In	Outside diameter at cut end of the conduit shall not be more than 1.5% smaller than outside diameter that measured 300mm away from the cut end of the conduit.
4.	Tensile Force at Yield	900N
5.	Pressure Test	No leakage at 175psi for 5 minutes.
6.	Reversion	<3%
7.	Minimum bending Radius	10D
8.	Friction Reduction	Lubrication materials shall be compatible with the conduit & any cable jacketing.
9.	Coefficient of friction	<0.1
