摘要总结AI 辅助解读

该法规（49 CFR § 173.41）规定了未精炼石油产品在运输前的采样与测试程序要求。发货人必须建立书面程序，涵盖采样频率、方法、测试标准及质量控制，以确保货物正确分类和描述。程序需至少每年审查一次，并保留文档备查（最短一年）。DOT官员有权在合理时间地点查阅相关文档。此规定旨在通过标准化流程降低危险品误分类风险，确保包装兼容性。

(a) General. Unrefined petroleum-based products offered for transportation must be properly classed and described as prescribed in § 173.22, in accordance with a sampling and testing program, which specifies at a minimum:

- (1) A frequency of sampling and testing that accounts for any appreciable variability of the material ( e.g., history, temperature, method of extraction [including chemical use], location of extraction, time of year, length of time between shipments);

- (2) Sampling prior to the initial offering of the material for transportation and when changes that may affect the properties of the material occur ( i.e., mixing of the material from multiple sources, or further processing and then subsequent transportation);

- (3) Sampling methods that ensure a representative sample of the entire mixture, as offered, is collected;

- (4) Testing methods that enable classification of the material under the HMR;

- (5) Quality control measures for sample frequencies;

- (6) Duplicate sampling methods or equivalent measures for quality assurance;

- (7) Criteria for modifying the sampling and testing program; and

- (8) Testing or other appropriate methods used to identify properties of the mixture relevant to packaging requirements ( e.g., compatibility with packaging, identifying specific gravity for filling packages).

(b) Certification. Each person who offers a hazardous material for transportation shall certify, as prescribed by § 172.204 of this subchapter, that the material is offered for transportation in accordance with this subchapter, including the requirements prescribed by paragraph (a) of this section.
(c) Documentation, retention, review, and dissemination of program. The sampling and testing program must be documented in writing ( i.e. hardcopy or electronic file thereof) and must be retained for as long as the sampling and testing program remains in effect, or a minimum of one year. The sampling and testing program must be reviewed at least annually and revised and/or updated as necessary to reflect changed circumstances. The most recent version of the sampling and testing program must be available to the employees who are responsible for implementing it. When the sampling and testing program is updated or revised, all employees responsible for implementing it must be notified, and the most recent version must be made available.
(d) Access by DOT to program documentation. Each person required to develop and implement a sampling and testing program must maintain a copy of the sampling and testing program documentation (or an electronic file thereof) that is accessible at, or through, its principal place of business, and must make the documentation available upon request at a reasonable time and location to an authorized official of the Department of Transportation.
