HD 523.3.100 to 105 S1:1990

Specification for flexible insulating sleeving - Part 3: Specification requirements for individual types of sleeving - Sheets 100 to 105: Extruded PVC sleeving

Scope

This standard gives requirements for non-heat-shrinkable sleeving of circular cross-section, extruded from PVC - Sheets 100 and 103 cover sleeving 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/yellow - It is also available in transparent form
