What are this years’ changes in the RHP product certification scheme? 

1 april 2019

The RHP quality mark for substrates is reviewed every year, in part based on developments in the field. Changes to the content of the RHP product certification scheme are therefore made every year. As of 1 May the new norms apply. What are the changes this year?

The most important decisions of the Central Board of Experts are explained below. Certified companies need to have introduced all the current requirements of the RHP certification scheme in their quality management system before the 1 May.

System for phytosanitary safety (module 210)

This module describes the general product requirements for the fields of application RHP Horticulture and RHP Consumer. A description of the system for phytosanitary safety is new. With an on-site risk inventory the phytosanitary risk level is determined for every raw material (e.g. wood fibre, compost) or its component (e.g. wood chips, vegetable waste derived from planting and maintaining private and public green areas, forests and nature areas and watercourses). There are six risk levels in which a raw material or component can be categorised. The risk level determines the frequency of the risk inventory and whether or not a raw material or component needs to complete a mandatory hygienisation process. A phytosanitary safe substrate minimizes the risks for the culture.

End products Consumer based on performance (module 731)

The composition of consumer potting soils changes and the fraction of renewable raw materials increases. This situation has led to a new possibility to assess aspects such as product quality, growth and safety of the RHP Consumer products. In this new module the new method is described. Potting soils need to be produced with known and controlled raw materials. In this way the RHP Consumer quality mark remains the foundation of controlled quality, safe products and positive experiences for consumers. Apart from this new procedure, the existing control system (module 730) remains in use. This means that a certified company can choose between the two procedures.

A list of the changes 

Module Change
210 The system for phytosanitary safety is added.
270 For B and BE products a packaging label is made available.
300 The C product “packed biological products for protecting, fertilizing or improving the growth” will be removed from the list as of 1-2-2020, after a transition year.

460 The legibility of the norms has been improved.
490 The suppliers assessment needs to be executed at least every 3 months. Apart from that, affairs such as name and address data need to be registered.
560, 570 Norms for the temperature of the peat and the procedure of measuring have been included in these modules.
