At the sampling the standards ISO 2418, ISO 2419 as well as ISO 4044 are considered.

取样标准参考 ISO 2418, ISO 2419,ISO 4044

The OEKO‑TEX® Service Ltd. has defined, that basically at all quanti-tative chemical examinations of leather, the quantitative result is sta-ted under consideration of the dry mass of the leather.

OEKO‑TEX®协会规定，在皮革的所有定量化学检验中，定量结果基本上以皮革的干质量为准进行计算。

The semi-finished leather (Wet-blue, Wet-white, Wet-brown, Wet-green) has to be air dried before the weigh out is performed. This is valid for all analyses (inclusive the determination of the dry mass). The air drying requires at least 24 h.

半成品皮革（蓝湿皮、白湿皮、棕湿皮、绿湿皮）在称重前必须风干，这一要求对所有分析均有效（包括干质量的测定）。风干至少需要 24 小时。

The OEKO‑TEX® Service Ltd. has defined due to the optional possi-bility given in the standard ISO 4044 that the leather samples are al-ways cut in small pieces and are not milled. This is valid both for the determination of the dry mass and for all chemical analyses.

OEKO‑TEX®Service Ltd.根据标准 ISO 4044 中的另一种可能性规定，始终将皮革样品切成小片，且不经研磨。这一要求对干质量的测定和所有化学分析均有效。

In case an article, which shall be certified according to LEATHER STANDARD by OEKO‑TEX®, contains also textile and non‑textile (e.g. metallic) components, these components are tested according to the conditions and criteria of the STANDARD 100 by OEKO‑TEX® and the methods used there. For this purpose at this point it is refer-red to the corresponding documents.

如果根据 LEATHER STANDARD by OEKO‑TEX®认证的制品还含有纺织品和非纺织品（如金属）组件，则应根据 STANDARD 100 by OEKO‑TEX®的条件和标准及其规定的方法对这些组件进行检测。为此，其他相应文件中已对这一规定进行了引用。
