JIS Z 2343-3:2017描述了用于JIS Z 2343-1和JIS Z 2343-2的三种参考试块:1型参考试块用于确定荧光和彩色对比渗透剂产品系列的灵敏度水平；2型和3型对比试块用于常规评估荧光和彩色对比渗透剂设施以及在用渗透剂的性能。参考试块的使用条件与JIS Z 2343规定的试板相同- 1和JIS Z 2343-2。

JIS Z 2343-3:2017 describes three types of reference blocks to be used for JIS Z 2343-1 and JIS Z 2343-2: Type 1 reference blocks are used to determine the sensitivity levels of both fluorescent and colour contrast penetrant product families; Type 2 and Type 3 reference blocks are used for routine assessment of the performance of both fluorescent and colour contrast penetrant facilities, and in-use penetrant. The reference blocks are used in the same conditions as those of test panels according to JIS Z 2343-1 and JIS Z 2343-2.
