Significance and Use5.1 This standard practice i
39、s designed to specify the mini-mum training and testing required of HFE operators traineesbefore they obtain a Heat Fusion Equipment Operator Quali-fication card. It will allow the industry to require the “HFE”operators be trained and qualified to an approved procedurebefore they can heat fuse PE or
40、 PA pipe in the field. Thestandard practice will bring more competency in the operatorsand more consistency in the training they receive.6. Training and Testing Procedures6.1 Butt Fusion with hydraulically operated fusion ma-chines for PE or PA pipe and fittings.6.1.1 Training Curriculum:6.1.1.1 The
41、 training shall be provided by a qualified “HFE”operator training instructor having the skill/experience de-scribed in Annex A1. The heat fusion course shall be com-prised of any combination of fusion machines based on therequirements of the pipeline operators. This training shall begiven as individ
42、ual modules or combined to suit requirements.6.1.1.2 The training shall be comprised of general informa-tion in the areas outlined in Table 1. It shall also cover thepractical information in the areas outlined in Table 2. Thisincludes training on the proper and safe operation of the heatfusion equip
43、ment the operator is being qualified on and how touse the equipment to make a heat fusion joint that satisfies thespecified heat fusion procedure or standard. This also includesmaking a minimum of two joints on the training equipment.The general training shall be taken in a class, in an internetcour
44、se, or a combination of both.6.1.2 HFE Operator Testing Requirements:6.1.2.1 The testing will be conducted by the Heat FusionEquipment Operator Training Organization after the generaland practical training is completed.6.1.2.2 After the completion of the general and practicaltraining, the HFE operat
