ISO 10147 requires test samples made from crosslinked polyethylene (PE-X) to be stored in a specified, boiling solvent for a specific
period of time and that the percent by weight of insoluble material is then measured. The percentage of insoluble material must be
recorded to express the degree of crosslinking. For this procedure, IPT recommends a laboratory assembly consisting of a round
glass flask with a heating jacket, a Dimroth cooler, a ring stand with suitable clamps and test holders with lids for the sample. To
complete the assembly, you will also require a heating cabinet (see H3014), an analytical balance (see H3000) and a lathe.
