BS 6893-3-100 to 105:1995 Flexible insulating sleeving for electrical purposes. Part 3. Specification for requirements for individual types of sleeving - Extruded PVC sleeving
Printed version of this is available at library. To request, please e-mail to referencepk@usm.my and include a copy of this record in your e-mail.
This standard gives requirements for non-heat-shrinkable sleeving of circular cross-section,
extruded from PVC.
Sheets 100 and 103 cover sleeving having a temperature index of 90, Sheets 101 and 104 cover
sleeving having a temperature index of 105, and Sheets 102 and 105 cover sleeving formulated to be
flexible at -65 °C.
Sheets 100, 101 and 102 employ bilateral tolerances for the bore diameter; Sheets 103, 104 and
105 employ unilateral positive tolerances. The bilateral tolerances given in Sheets 100, 101 and 102
are preferred but the unilateral tolerances in Sheets 103, 104 and 105 may continue as an interim
measure.
Each sheet covers three levels of wall thickness: "thin wall", "standard wall", and "thick wall",
related to nominal bore diameter and with corresponding differences in requirements for break-
down voltage.
The sleeving is normally available in bore sizes 0.3 mm to 50 mm and in the following opaque
colours:
black, blue, brown, grey, green, orange, pink, red, turquoise, violet, white, yellow and green/yel-
low.
It is also available in transparent form.
