(38)To further decrease the cost to micro-enterprises of placing construction products, which they have manufactured, on the market, it is necessary to provide for simplified procedures for the assessment of performance when the products in question do not imply significant safety concerns while complying with the applicable requirements, whatever the origin of those requirements. Enterprises applying those simplified procedures should, in addition, demonstrate that they qualify as micro-enterprises. Moreover, they should follow the applicable procedures for verification of constancy of performance provided for in the harmonised technical specifications for their products.
