い、の項目を満たすものを合格とする。The UL standard 758 test is applied to wiring materials such as radios and televisions for export to the United States, and is a famous method as "FR-1 test", which has a structure shown in FIG.
Set the position of the tylyl burner 4 so that the tip of the reducing flame 2 hits the position of 76.2 mm from the lower end of the sample 1 of mm.
The length of the reducing flame 2 is approximately 35 mm, the length of the oxidizing flame is approximately 130 mm, and the position of the indicator flag 5 is 254 mm above the flame contact point.
Lay surgical cotton on the floor 165.1 mm below the bottom edge of the sample.
Repeat the operation of applying the flame for 15 seconds and resting for 15 seconds 5 times. After the 5th flame contact, the flame does not burn for 1 minute or more, the indicator flag burns 1/4 or less, and the surgical cotton does not burn due to dripping. Those that meet the criteria are accepted.

べ、流水なきものを合格とした。In the water permeability test, as shown in Fig. 2, a cable 7 having a length of 1 m was connected to a tube 8 containing water having a height of 1 m,
The other end of the cable was checked for water leakage, and the one without running water was passed.
表１の結果から明らかなように、No.１１の従来品では
難燃効果は認められるものの、透水性試験ではケーブル
端末より水が流出し防水性に欠けることが判明した。こ
の原因としてはジエリー粘度が高いため、完全に充填が
できなかつたことによると考えられる。 As is clear from the results in Table 1, the conventional product of No. 11 has a flame-retardant effect, but in the water permeability test, it was found that water leaked from the cable end and lacked waterproofness. It is considered that the reason for this is that it was not possible to completely fill it due to the high viscosity of Jerry.

う優れた効果を奏するものである。(Effects of the Invention) As described in detail above, since the waterproofing mixture used for the conventional cable was easily flammable, it was difficult to make it flame-retardant. However, the flame-retardant waterproofing for cables of the present invention was difficult. Since the water-soluble composition suppresses the fluidity by adding a gelling agent to the silicone oil for waterproofing and thixotropic property to the silicone oil, a flame retardant such as aluminum hydroxide or phosphate ester is added. In addition to having a high flame retardant effect, improved waterproofness, flame retardancy, and filling properties, it has an excellent effect of not solidifying at low temperatures.
