ISTA Sampling Calculator

ISTA Bulking and Sampling Committee has created a Sampling Calculator, which may be installed as an application on a desktop, Android, or iOS device. 

With this Application, samplers no longer need to carry ISTA Rules with them when they are going to sample seed lots; they will have all the information they need on their smartphone.

ISTA Sampling Calculator Application automatically calculates the minimum number of primary samples to be taken (including for heterogeneity testing) of all kinds of seeds, all sizes and types of containers and packaging, as well as the seed stream. All that the sampler needs to do is to enter a few variables pertaining to the specific seed lot being sampled.

The Application also provides all relevant information of the species being sampled, such as maximum seed lot size, submitted sample size, including for moisture testing, as well as the working sample sizes for purity and other seed determination. It also has been recently enhanced to include all the information of Table 3B, i.e. the Family name, is it a chaffy species or not, the PSD Number, as well as the Pure Seed Definition itself, for each species.

Sampling Calculator


ISTA Bulking and Sampling Committee (BSC) is continuing with the translation of the Sampling Calculator Application into multiple languages – in addition to English, it is already available in Afrikaans, Arabic, Danish, Dutch, French, Hungarian, Italian, Polish, Portuguese, Russian, Slovak, Spanish, Swedish and Turkish.

To select a language, please click on the language icon that you will find at the top right-hand corner of the first page of the Sampling Calculator Application.

The Committee would like to invite ISTA Members, that would like to have the Application also in their language, to volunteer to do the translations for their respective language.
 
There is no limit to the number of languages it could be translated into. Eddie Goldschagg of the Bulking and Sampling Committee will provide a Google spreadsheet, containing the English wording that needs to be translated, to the volunteer translators. 

Should you be interested to become a volunteer translator of ISTA Sampling Calculator, please get in touch with Eddie via the application's email
