Introduction
Background of Standard Revision and Technological Evolution
GB/T12729.2-2020, as the core part of the spice standardization system, inherits the technical accumulation of the 1991 and 2008 versions, and mainly achieves three upgrades: standardization of terminology system, refinement of operation procedures and clarification of equipment requirements. The 2020 version adjusts the sampling location requirements to normative annotations, and adds a list of special equipment in Chapter 4, reflecting the requirements of modern testing technology for tool standardization.
Analysis of key term definitions
| Terms | 2020 version definition | 2008 version comparison |
|---|---|---|
| Basic sample | A small amount of goods taken from one location in the batch (with confirmation of multi-point sampling) | The definition directly includes the requirement of multi-point sampling |
| Mixed sample | The sample after all basic samples are mixed evenly | The standard of mixing uniformity is not specified |
Key points of sampling operation
Case: When a spice company processed a 50kg peppercorn delivery batch, it followed the standard requirements:
- Calculate the number of packages to be sampled: 50-100 packages are sampled at 10%, so 5 packages
- Use a standard sampling stick to take basic samples in different directions
- After mixing, divide into four equal parts, of which the arbitration sample is sealed in a glass container
Comparison of old and new standard technologies
| Elements | 2020 Edition | 2008 Edition |
|---|---|---|
| Chapter Structure | Added Chapter 4: Sampling Equipment Specifications | Equipment requirements are scattered in the operating terms |
| Sampling location | Multi-point sampling is explained through annotations | Write directly into the definition text |
Implementation suggestions and precautions
1. Equipment verification: The sampling stick should meet the requirements of GB/T 6679 for solid sampling tools, and cleanliness verification should be carried out before use
2. Environmental control: When the humidity is higher than 65%, the dehumidification equipment should be started to prevent the spices from absorbing moisture and affecting the representativeness of the samples
3. Arbitration storage: It is recommended that arbitration samples be stored in brown glass bottles filled with nitrogen and the temperature should be controlled at 15-25℃
