标准范围

ISO 11666:2010规定了铁素体钢全熔透焊接接头的超声波验收等级2和3，对应于ISO 5817质量等级B和C。ISO 11666:2000中不包括对应于ISO 5837质量等级D的验收等级，因为通常不要求对该焊接质量进行超声波检测。这些验收等级适用于根据ISO 17640进行的测试。ISO 11666:2010适用于厚度为8 mm至100 mm的全熔透铁素体钢焊缝的检查。它也可用于100mm以上的其他类型的焊缝、材料和厚度，前提是进行检查时必须考虑到部件的几何和声学特性，并且可采用足够的灵敏度，以达到ISO 11666:2010的验收标准。ISO 11666:2010中使用的探头的标称频率在2 MHz和5 MHz之间，除非衰减或更高分辨率的要求需要其他频率。需要仔细考虑将这些接受水平与超出该范围的频率结合使用。

ISO 11666:2010 specifies ultrasonic acceptance levels 2 and 3 for full penetration welded joints in ferritic steels, which correspond to ISO 5817 quality levels B and C. An acceptance level corresponding to ISO 5817 quality level D is not included in ISO 11666:2010 as ultrasonic testing is generally not requested for this weld quality.These acceptance levels are applicable to testing carried out in accordance with ISO 17640.ISO 11666:2010 applies to the examination of full penetration ferritic steel welds, with thicknesses from 8 mm to 100 mm. It can also be used for other types of welds, materials and thicknesses above 100 mm, provided the examinations have been performed with necessary consideration of the geometry and acoustic properties of the component, and an adequate sensitivity can be employed to enable the acceptance levels of ISO 11666:2010 to be applied. The nominal frequency of probes used in ISO 11666:2010 is between 2 MHz and 5 MHz unless attenuation or requirements for higher resolution call for other frequencies. The use of these acceptance levels in conjunction with frequencies outside this range needs to be considered carefully.
