ISO 13631:2002给出了石油和天然气工业中用于压缩碳氢化合物气体的包装撬装式、往复式、可分离式或整体式压缩机及其润滑气缸及其原动机的设计、材料、制造、检验、测试和装运准备的要求和建议。 它还适用于所有必要的辅助设备，如水和气体冷却器、消音器、排放控制设备、过滤器、分离器、控制面板、管道等。，需要按照购买规范安装可操作的单元，并旨在最大限度地减少现场施工和现场购买的设备。 ISO 13631:2002不适用于以下情况: ISO 13707涵盖的石油和天然气工业的往复式压缩机；柱式压缩机；非润滑压缩机；具有也用作十字头的行李箱型(汽车型)活塞的压缩机；流量计压力为0.9兆帕（9巴）或以下的公用或仪表空气压缩机；由柴油机、燃气轮机和蒸汽轮机原动机驱动的压缩机。

ISO 13631:2002 gives requirements and recommendations for the design, materials, fabrication, inspection, testing and preparation for shipment of packaged skid-mounted, reciprocating, separable or integral compressors with lubricated cylinders and their prime movers, for use in the petroleum and natural gas industries for the compression of hydrocarbon gas. It is also applicable to all necessary auxiliary equipment, such as water and gas coolers, silencers, emission control equipment, filters, separators, control panel, piping, etc., required to install an operable unit in compliance with the purchase specifications and with the intent of minimizing field construction and field-purchased equipment. ISO 13631:2002 is not applicable to the following:

• reciprocating compressors for petroleum and natural gas industries covered by ISO 13707;
• column-mounted compressors;
• non-lubricated compressors;
• compressors having trunk-type (automotive-type) pistons that also serve as crossheads;
• utility or instrument air compressors with a discharge gauge pressure of 0,9 MPa (9 bar) or less;
• compressors driven by diesel engine, gas turbine and steam turbine prime movers.
