ISO 11012:2009描述了两种开环测试方法，用于在严格控制的测试条件下确定车辆响应特定类型的转向输入的中心操纵特性: 编织测试，以及 过渡测试。 ISO 11012:2009适用于重型车辆，即ISO 3833中定义的商用车辆、商用车辆组合、公共汽车和铰接式公共汽车（根据ECE和EC车辆分类，最大重量超过3.5吨的卡车和拖车，以及最大重量超过5吨的公共汽车和铰接式公共汽车，类别M3、N2、N3、O3和O4）。

ISO 11012:2009 describes two open-loop test methods for determining on-centre handling characteristics of a vehicle in response to specific types of steering input under closely controlled test conditions:

• the weave test, and
• the transition test.

ISO 11012:2009 applies to heavy vehicles, i.e. commercial vehicles, commercial vehicle combinations, buses and articulated buses as defined in ISO 3833 (trucks and trailers with maximum weight above 3,5 tonnes and buses and articulated buses with maximum weight above 5 tonnes, in accordance with ECE and EC vehicle classification, categories M3, N2, N3, O3 and O4).
