4 CATEGORY 2 — FASTENERS INTENDED FOR GENERAL PURPOSE APPLICATIONS
4.1 Basic Category Structure A Category 2 plan utilizes documented and verifiable in-process controls structured at the producer’s discre- tion. Parts and documentation shall be in compliance with the requirements stated in this Standard and all supplemental requirements agreed on between producer and purchaser. The producer shall provide evidence of the system structure upon request. Final inspection shall be performed by the producer with sample size depen- dent on lot size. Category 2 shall be the default category for fastener manufacturers in the absence of a specified category on a purchase order.
4.2 Designation Category 2 should be designated on purchase docu- ments by specifying “Quality Assurance Provisions per Category 2 of ASME B18.18 are required” or another equivalent statement.
4.3 Raw Material
4.3.1 General. Unless otherwise specified in the individual product standard, raw materials (rod, wire, or bar) shall be reviewed to determine that each coil or bundle has a Mill Identification and that each heat (batch, melt, cast, etc.) is accompanied by a Mill Certification of analysis or the equivalent. The raw mate- rial or its accompanying mill certification shall be inspected prior to release for fabrication to verify that it conforms to the specified material requirements.
4.4 Final Inspection and Test Final inspection shall be completed by a person that has been properly trained and appointed by the pro- ducer. Minimum sample sizes shall be determined using Table 2. The attributes in Table 1 shall be inspected unless otherwise specified by the purchaser or otherwise indicated in the product standard.
5 CATEGORY 3 — FASTENERS INTENDED FOR SPECIALIZED APPLICATIONS
5.1 Basic Category Structure A Category 3 plan utilizes documented and verifiable in-process controls structured at the producer’s discre- tion. Parts and documentation shall be in compliance with requirements stated in this Standard and all supple- mental requirements agreed to between producer and purchaser. The producer shall have an independently registered quality management system. Final inspection shall be performed by a facility accredited to the require- ments of ISO/IEC 17025. 5.2 Designation When required, Category 3 shall be designated on purchase documents by specifying “Quality Assurance Provisions per Category 3 of ASME B18.18. are required” or another equivalent statement. Absence of such state- ment will default seller to Category 2.
5.3 Quality Management System Producers of Category 3 fasteners shall have an inde- pendently accredited Quality Management System that complies with the requirements of an internationally accepted standard such as ISO 9001 or ISO/TS 16949.
5.4 Raw Material
5.4.1 General. Raw materials (rod, wire, or bar) shall be reviewed to determine that each coil or bundle has a mill identification and that each heat (batch, melt, cast, etc.) is accompanied by a mill certification of analy- sis or the equivalent. Additionally, a single sample shall be checked chemically, by an accredited laboratory, for each heat. The raw material and its accompanying mill certification shall be inspected prior to release for fabri- cation to verify that it conforms to the material require- ments specified.
5.5 Final Inspection and Test Final inspection shall be performed by an ISO/IEC 17025 accredited laboratory. The sample sizes in Table 3 shall be used unless the producer has in- process records (para. 2.2), in which case the sample sizes in Table 2 may be used. Final inspection verifies that required process steps were performed and that Table 1 and Nonmandatory Appendix A, Table A-1 features were inspected/tested. Data on Type I characteristics shall be provided when the purchaser requires a test report. Evidence of testing of Types II and III characteristics shall be provided upon request. 5.6 Upgrade Option for Resellers A reseller may, at their own discretion, use this process to upgrade existing inventory from Category 2 to Category 3.
5.6.1 Raw Material Certification. The reseller shall verify that the raw material meets the requirements of the applicable product and/or material standards. This may be performed by verifying the data on the original steel mill certificate or the Material Test Report from the original fastener manufacturer.
5.6.2 Final Inspection for Upgrade. The reseller shall randomly select fasteners from a verifiable single lot and conduct the final inspection in a facility accredited
