Introduction
Interpretation of the National Standard of the People's Republic of China GB/T 34743—2017 Oak Solid Wood Flooring
Introduction
GB/T 34743—2017 Oak Solid Wood Flooring Standard is an important specification of the Chinese wood industry, which aims to unify the terminology, classification, quality requirements and inspection methods of oak solid wood flooring. This standard applies to solid wood flooring made of wood from the genus Quercus of the Fagaceae family, covering various technical indicators from raw materials to finished products.
1. Terms and Definitions
According to the standard, oak solid wood flooring is a floor directly processed from wood from the genus Quercus of the Fagaceae family, commonly known as "oak solid wood flooring". Among them:
- Machine burn: refers to the phenomenon that the board surface becomes black due to the friction between the tool and the wood surface during processing.
2. Classification of oak solid wood flooring
Oak solid wood flooring can be divided into the following categories according to wood species, surface effects and finishing methods:
| Classification dimensions | Specific classification |
|---|---|
| Wood species | a) Red oak (Erythrobalanus Spach); b) White oak (Lepidobalanus Endl.) |
| Surface effect | a) Flat oak solid wood flooring; b) Non-flat (antique) oak solid wood flooring. |
| Finishing method | a) Painted oak solid wood floor (lacquer, oil finish); b) Unpainted oak solid wood floor. |
3. Appearance quality requirements
Appearance quality is an important indicator for measuring oak solid wood flooring. The standard clearly stipulates the appearance quality requirements of different grades of products.
Case Analysis: Comparison between Superior Products and Qualified Products
| Items | Superior Products | First-class Products | Qualified Products |
|---|---|---|---|
| Sapwood | Not allowed | Area<1/10 board area, and sapwood thickness not more than 3mm | Area<1/4 board area, and sapwood thickness not more than 5mm |
| Live Knot | Diameter ≤15mm, quantity ≤5 (length ≤760mm) | 15mm| No size or quantity limit | |
4. Physical and mechanical performance indicators
The physical and mechanical properties of oak solid wood flooring are directly related to its service life and stability.
| Item | Unit | Superior product | First-class product | Qualified product |
|---|---|---|---|---|
| Moisture content | % | 7.0≤Moisture content≤Regional balance value | Same as above | Same as above |
| Paint film surface wear resistance | ≤0.08 | ≤0.10 | ≤0.15 |
5. Inspection methods and rules
The standard stipulates a strict inspection process, including factory inspection and type inspection.
Sampling Scheme Comparison
| Batch Range | Sample Size | Acceptance Number Ac | Rejection Number Re |
|---|---|---|---|
| ≤25 | 3 | 0 | 1 |
| 91~280 | 8 | 2 |
Implementation Suggestions
To ensure the quality of oak solid wood flooring, it is recommended that manufacturers:
- Carry out classification management strictly in accordance with the standards.
- Optimize the inspection process and improve the inspection efficiency.
- Strengthen employee training and enhance quality awareness.
