See d’Hedouville v. Pioneer Hotel Co., 552 F.2d 886, 890 (9th Cir.1977) (holding that district court properly allowed experiment evidence regarding flammability of carpet sample despite differences between test fire and actual fire); Canada Life Assur. Co. v. Houston, 241 F.2d 523, 537 (9th Cir. 1957) ("[T]he conditions surrounding a test or experiment of this nature need not be identical with those existing at the time of the occurrence in question provided there is a substantial similarity.")
