ASLN (Authorized Service Laboratories Naktuinbouw)
ASLN authorized laboratories can use the results of tests to safeguard the health of propagating material:
- for the quality-plus systems Naktuinbouw Elite and Naktuinbouw Select Plant
- within NAL (Naktuinbouw Authorized Laboratories)
- for Naktuinbouw quality inspections
Naktuinbouw bases ASLN authorization on three principles
- working using Naktuinbouw approved protocols
- the results of proficiency tests organized by Naktuinbouw
- the results of the annual audits
Laboratories that work in compliance with the ASLN Conditions give their clients the assurance of reliable test results. Authorized laboratories will be granted the ASLN certificate. An ASLN authorized laboratory can only issue a laboratory report if the results concern a crop that is covered by our inspections.
ASLN authorization consists of three modules: quality assurance management system, sampling and testing.
- Quality assurance management system
The quality assurance management system module sets requirements for organization, education and training of employees, the quality manual, document registration and management, audits, complaints, management responsibility and proficiency tests.
The sampling module sets requirements regarding how sampling takes place and is dealt with at the company. This applies to sampling of seeds as well as (parts of) plants and soil. This is an essential part of the system, as without a good representative sample there can be no relationship between the test result - no matter how well the test was performed - and the particular lot of material delivered, or parcel of land, concerned.
The testing module sets requirements regarding how testing is performed at the laboratory. The test protocols must be approved by Naktuinbouw. ASLN also sets requirements regarding the facilities, equipment, reference materials, subcontracting, laboratory results and purchasing.
The Naktuinbouw board establishes our inspection fees each year. The fees are subsequently approved by the Minister of Agriculture, Nature and Food Quality. The costs are charged based on the cost-maker cost-bearer principle. The fees for inspection can be found here Rates/fees.
