1.1 本规程描述了热熔设备（HFE）操作员在但不限于现场环境中的培训、评估和资格认证标准，以建立和保持聚乙烯（PE）和聚酰胺（PA）管道系统连接的能力。 1.2 本HFE操作员培训和资格认证适用于将PE管和配件与所用热熔程序或标准中规定的其他相关聚合物化学的PE管和配件进行热熔连接。它也适用于PA管道和配件与所用热熔程序或标准中规定的相同聚合物化学的其他PA管道和配件的热熔连接。 PE管和管件与PA管和管件之间的热熔合为 不是 允许。 1.3 HFE操作员的培训和资格应适用于PE或PA管道产品的对接熔合，使用HFE操作员使用的熔合机的特定品牌和尺寸范围以及规定的热熔程序或标准。如果HFE操作员受训者要求，培训还应包括所用热熔程序或标准中规定的PE管和相关聚合物化学配件的鞍座和/或承插熔合。 本标准不包括这些管道产品的电熔培训。 1.4 HFE操作员资格应针对一个特定制造商的熔合机或该制造商的液压熔合机或设备的尺寸范围，这些熔合机或设备均以相同的方式运行，具有相同的液压设计和控制以及相同的加热器和面板设计。对于较小的管道尺寸（6英寸及以下），可以在特定的熔合机上或对接、鞍座和/或承插熔合机或设备的组合上进行鉴定。 1.5 HFE操作员资格应符合PE和PA管道规定的特定热熔程序或标准。对于PE管和管件，这应包括实践 F2620 或其他公司或管道制造商的程序，或其组合。对于PA-11管道和配件，这应包括塑料管道协会（PPI）技术报告TR-45或其他公司或管道制造商的程序。对于PA-12管道和配件，这应包括实践 F3372 或其他公司或管道制造商的程序，或其组合。 对于其他PA管道材料，使用其他公司或管道制造商的程序。 1.6 以英寸-磅为单位的数值应视为标准值。本标准不包括其他计量单位。 1.7 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本标准实践旨在规定HFE操作员受训者在获得热熔设备操作员资格证之前所需的最低培训和测试。这将允许行业要求“HFE”操作员在现场对PE或PA管道进行热熔合之前，必须经过培训并符合批准的程序。标准实践将为操作员带来更多的能力，并使他们接受的培训更加一致。

1.1 This practice describes criteria for the training, assessment and qualification of heat fusion equipment (HFE) operators in, but not limited to, a field environment in order to establish and maintain competency in the joining of Polyethylene (PE) and Polyamide (PA) piping systems. 1.2 This HFE operator training and qualification is applicable to heat fusion joining of PE pipe and fittings to other PE pipe and fittings of related polymer chemistry specified in the heat fusion procedures or standards used. It is also applicable to heat fusion joining of PA pipe and fittings to other PA pipe and fittings of the same polymer chemistry specified in the heat fusion procedures or standards used. The heat fusion between PE pipe and fittings to PA pipe and fittings is NOT allowed. 1.3 The HFE operator training and qualification shall be for butt fusion for either PE or PA piping products, using the specific brand and size range of fusion machine to be used by the HFE operator and the heat fusion procedures or standards specified. If the HFE operator trainee requests, the training shall also include saddle and/or socket fusion of PE pipe and fittings of related polymer chemistry specified in the heat fusion procedures or standards used. This standard does not include training on the electro-fusion of these piping products. 1.4 The HFE operator qualification shall be for one specific manufacturer’s fusion machine or a size range of that manufacturer’s hydraulic fusion machines or equipment that all operate in the same manner with the same hydraulic design and controls and the same heater and facer design. For smaller pipe sizes (6 in. and smaller), the qualification can be on a specific fusion machine or a combination of butt, saddle and/or socket fusion machines or equipment. 1.5 The HFE operator qualification shall be on specific heat fusion procedures or standards specified for PE and PA pipes. For PE pipe and fittings, this shall include Practice F2620 or other company or pipe manufacturer’s procedures, or a combination thereof. For PA-11 pipe and fittings, this shall include Plastics Pipe Institute (PPI) Technical Report TR-45 or other company or pipe manufacturer’s procedures. For PA-12 pipe and fittings, this shall include Practice F3372 or other company or pipe manufacturer’s procedures, or a combination thereof. For other PA pipe materials, use other company or pipe manufacturer’s procedures. 1.6 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This standard practice is designed to specify the minimum training and testing required of HFE operators trainees before they obtain a Heat Fusion Equipment Operator Qualification card. It will allow the industry to require the “HFE” operators be trained and qualified to an approved procedure before they can heat fuse PE or PA pipe in the field. The standard practice will bring more competency in the operators and more consistency in the training they receive.
