The helmet shall be returned to the conditioning environment within 3 minutes after it was removed, and shall remain in the conditioning environment for a minimum of 2 minutes before testing is resumed. If the helmet is out of the conditioning environment beyond 3 minutes, testing shall not resume until the helmet has been reconditioned for a period equal to at least 5 minutes for each minute the helmet was out of the conditioning environment beyond the first 3 minutes, or for 4 hours, (whichever reconditioning time is shorter) before testing is resumed.\n(d) Prior to being tested for impact attenuation, helmets 1-4 (conditioned in ambient, high temperature, low temperature, and water immersion environments, respectively) shall be tested in accordance with the dynamic retention system strength test at § 1203.16. Helmets 1-4 shall then be tested in accordance with the impact attenuation tests on the flat and hemispherical anvils in accordance with the procedure at § 1203.17. Helmet 5 (ambient-conditioned) shall be tested in accordance with the positional stability tests at § 1203.15 prior to impact testing. Helmets 5-8 shall then be tested in accordance with the impact attenuation tests on the curbstone anvil in accordance with § 1203.17. Table 1203.13 summarizes the test schedule.\nTable 1203.13—Test Schedule\n§ 1203.14 Peripheral vision § 1203.15 Positional stability § 1203.16 Retention system strength § 1203.17 Impact tests\nAnvil Number of Impacts\nHelmet 1, Ambient X X X Flat X Hemi 2 2\nHelmet 2, High Temperature X X Flat X Hemi 2 2\nHelmet 3, Low Temperature X X Flat X Hemi 2 2\nHelmet 4, Water Immersion X X Flat X Hemi 2 2\nHelmet 5, Ambient X X Curb 1\nHelmet 6, Low Temperature X Curb 1\nHelmet 7, High Temperature X Curb 1\nHelmet 8, Water Immersion X Curb 1","path":["Title 16—Commercial Practices","CHAPTER II—CONSUMER PRODUCT SAFETY COMMISSION","SUBCHAPTER B—CONSUMER PRODUCT SAFETY ACT REGULATIONS","PART 1203—SAFETY STANDARD FOR BICYCLE HELMETS","Subpart A—The Standard"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-16.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:24:29Z","sha256":"41dfc815bab0a43547dca294c852fb66bbacba5de2ff485e6a2317be1b19e243","source_id":"us-cfr","stale":true,"prev":"us/16-cfr-1203.12","next":"us/16-cfr-1203.14"},"notice":"GroundRules: Original legal text.
