ČSN EN 17702-1 This document specifies sampling plans and methods of representative sampling of plant biostimulants to obtain samples for physical, chemical and biological analysis. It is applicable to the sampling of batches of plant biostimulants supplied or ready for supply to third parties, as such, or in smaller batches. This document is applicable to the blends of fertilizing products where a blend is a mix of at least two of the following component EU fertilising products: Fertilizers/Liming Materials/Soil Improvers/Growing Media/Inhibitors/Plant Biostimulants, and where the following category Plant Biostimulants is the highest percentage in the blend by mass or volume, or in the case of liquid form by dry mass. If Plant Biostimulants is not the highest percentage in the blend, the European Standard for the highest percentage of the blend applies. In case a blend of fertilizing products is composed of components in equal quantity or in case the component EU fertilising products used for the blend have identical formulations, the user decides which standard to apply. This document is intended to be used by manufacturers, buyers and competent authorities to obtain samples prior to transport and supply it to a laboratory for testing.

ČSN EN 17711 This document specifies a horizontal method for the detection of enteropathogenic Vibrio species (spp.), which causes human illness in or via the intestinal tract. The species detectable by the methods specified include Vibrio parahaemolyticus, Vibrio cholerae and Vibrio vulnificus. It is applicable to the microbial plant biostimulants. This document is applicable to the blends of fertilizing products where a blend is a mix of at least two of the following component EU fertilising products categories: Fertilizers, Liming Materials, Soil Improvers, Growing Media, Plant Biostimulants, and where the following category Plant Biostimulants is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If Plant Biostimulants is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a blend of fertilizing products is composed of components in equal quantity or in case the component EU fertilising products used for the blend have identical formulations, the user decides which standard to apply.

ČSN EN 17722 This document specifies a horizontal method for the enumeration and genus/species determination of mycorrhizal fungi in microbial plant biostimulants. This document is applicable to the blends of fertilizing products where a blend is a mix of at least two of the following component EU fertilising products categories: Fertilizers, Liming Materials, Soil Improvers, Growing Media, Plant Biostimulants and where the following category Plant Biostimulants is the highest percentage in the blend by mass or volume, or in the case of liquid form by dry mass. If Plant Biostimulants is not the highest percentage in the blend, the European Standard for the highest percentage of the blend applies. In case a blend of fertilizing products is composed of components in equal quantity or in case the component EU fertilising products used for the blend have identical formulations, the user decides which standard to apply.

ČSN EN 18034 This document specifies a laboratory method for the determination of chlorophyll a content in algae. The method was initially tested and evaluated on the microalgae species Nannochloropsis sp. and a heat treated algal product tomato soup with Nannochloropsis sp. supplement, and the macro algae species Ulva sp., Furcellaria lumbricalis, and Saccharina latissima. During an Interlaboratory Trial the method was tested on the microalgae species Nannochloropsis sp. and the macro algae species Saccharina latissima. The microalgae species Nannochloropsis sp. and Phaodactlylum sp. and the macro algae species Ulva sp. and Saccharina latissima were tested in a Round Robin test. This document is only validated for chlorophyll a, but it can be used for other chlorophylls as well.

ČSN EN 13160-7+A1 This European Standard gives requirements and the corresponding test/assessment methods applicable to leak detection lining kits and leak detection jacket kits. Leak detection lining kits and leak detection jackets kits intended to be used to create an interstitial space or leakage containment in single skin underground or above ground, non-pressurized, tanks designed for water polluting liquids. The kit has to be used only in conjunction with leak detection kits covered by EN 13160-2 to EN 13160-4.

ČSN EN 13160-3+A1 This European Standard gives requirements and the corresponding test/assessment methods applicable to leak detection kits based on the drop of the liquid level in the leak detection liquid reservoir. Leak detection kits are intended to be used with double skin, underground or above ground, non-pressurized, tanks designed for water polluting liquids. The liquid leak detection kits are usually composed of: - sensing device (liquid sensor); - evaluation device; - alarm device.
