A detailed plan of the construction and arrangement of the furnace apparatus may be obtained from the Commandant (CG-521).\n(b) Temperatures measured by the thermocouples are recorded by an instrument having a measuring range that corresponds to the temperature changes that occur during a furnace calibration or test. The temperature recording equipment is accurate to within at least 0.5 percent of temperatures recorded during a test.","path":["Title 46—Shipping","CHAPTER I—COAST GUARD, DEPARTMENT OF HOMELAND SECURITY","SUBCHAPTER Q—EQUIPMENT, CONSTRUCTION, AND MATERIALS: SPECIFICATIONS AND APPROVAL","PART 164—MATERIALS","Subpart 164.009—Noncombustible Materials for Merchant Vessels"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-46.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:22Z","sha256":"aac3f07ec393ff22e87b07f6c5fa95642567946711a5ab155b0c9436af24b120","source_id":"us-cfr","stale":true,"prev":"us/46-cfr-164.009-9","next":"us/46-cfr-164.009-13"},"notice":"GroundRules: Original legal text.
