Luka's quality policy is the most important part of the association's policy. Customers and clients can make high demands on the security that Luka members offer with regard to quality, reliability of delivery and compliance with specifications. Luka members are aware that quality is in the functioning of the organisation; quality problems often have an organisational cause. In order to meet the quality requirements, Luka members must say what they do and do what they say. And make this verifiable. Luka members have a quality system in accordance with, or derived from, ISO 9000. Luka members give their staff the opportunity to acquire skills through competence courses, safety courses, etc. All of this forms the basis for independent quality control by TÜV Rheinland Nederland B.V., who carry out the inspection and are responsible for the airtightness measurements carried out by the Luka members themselves. TÜV Rheinland Nederland B.V. carries out quality inspections based on a list of checkpoints drawn up on the basis of the quality standards, as laid down in this Quality Guide. Through regular inspections of the delivered and installed products by TÜV Rheinland Nederland B.V., it can be determined whether the Luka member meets the quality standards set out in this Quality Guide. Based on this inspection, TÜV Rheinland Nederland B.V. confirms the Luka member's quality guarantee annually by means of a "Product Label".

Associated members of Luka who produce and/or supply fittings and wish to carry out their own airtightness measurements also have the option of having their measurements checked annually by TÜV Rheinland Nederland B.V.. The correctness is guaranteed by means of a "Measuring Label".
