適用範囲

This standard is applicable to the procurement, storage, transportation, processing, and sales of commercial wheat. It establishes the terms, definitions, classification, quality requirements, and testing methods for wheat. It is not applicable to special varieties of wheat outside the specified classifications, such as those with purple or black seed coats. This standard replaces the previous GB 1351-2008.

技術要求

GB 1351-2023 specifies the quality requirements for wheat, categorizing it into five classes based on kernel hardness and seed coat color: hard white wheat, hard red wheat, soft white wheat, soft red wheat, and mixed wheat. The standard defines key parameters including test weight, which serves as the grading indicator, with Grade 3 as the median. The standard outlines limits for defected kernels (including insect-bored, diseased, and heat-damaged kernels) and impurities (subdivided into inorganic and organic). It also sets maximum thresholds for moisture content and requires normal color and odor. Compliance with these grading and quality parameters is mandatory for all commercial wheat transactions in China. Additionally, the standard details requirements for labeling, packaging, storage, and transportation to ensure product integrity. Packaging must be clean and secure, while storage must prevent contamination, moisture, and pest infestation.

試験方法

The standard references several testing methodologies to ensure accurate quality assessment. Key testing methods include: - Sampling and Sample Splitting: Conducted according to GB/T 5491. - Test Weight Measurement: Evaluated per GB/T 5498. - Impurities and Defected Kernels Inspection: Executed following GB/T 5494-2019. - Moisture Content Determination: Tested via GB 5009.3 (serving as the arbitration method) or GB/T 5497. - Wheat Hardness Testing: Measured using the hardness index method as per GB/T 21304.

よくある質問

What products are regulated under GB 1351-2023?

GB 1351-2023 regulates commercial wheat involved in procurement, storage, transportation, processing, and sales within China. It does not apply to special wheat varieties with unique seed coat colors like purple or black.

Are there any updates from the previous version of GB 1351?

Yes, compared to GB 1351-2008, the 2023 version modifies definitions for defected kernels and impurities, adds terms like heat-damaged kernel and useless wheat, and updates the moisture testing method to include GB 5009.3 as the basic arbitration method.

How is wheat graded under GB 1351-2023?

Wheat is primarily graded based on its test weight (bulk density). The standard sets specific minimum test weight limits for Grades 1 through 5, with Grade 3 being the median. Other factors like defected kernels and impurities must also meet specified limits.
