The quality of the products of Zwiesel Kristallglas AG and its subsidiaries depends not least on the quality of the supplies. It must therefore be ensured that all supplies and services meet the agreed requirements. The fulfilment of the respective quality requirements is a basic prerequisite and an essential component of every contract between the companies of Zwiesel Kristallglas AG and their suppliers. In order to meet the quality requirements of Zwiesel Kristallglas AG, it is necessary that the supplier has an up-to-date and effective quality assurance system. The supplier is responsible for the quality of his products.
Quality policy of Zwiesel Kristallglas AG
Quality management and the quality concept are anchored in such a way that we continuously and consistently pursue the improvement of services, products, processes and the organisation in all functional areas. The quality policy is defined in three principles:
Satisfied customers are our benchmark
The fulfilment of our customers' expectations is the benchmark for innovations, products, services and processes at Zwiesel Kristallglas AG. We guarantee the Zwiesel Kristallglas AG quality standard to our customers and partners worldwide.
Quality is the basis of our competitiveness
Each employee takes responsibility for the quality of his or her work and continuously develops the quality standards required at his or her workplace. We constantly monitor our quality standards and apply them to all contractors and suppliers of Zwiesel Kristallglas AG.
Faultlessness is our goal - continuous improvement is our way.
We ensure the suitability, stability and efficiency of all processes through prevention and continuous improvement, thus ensuring our future-oriented competitiveness.
Quality in procurement
Purchased materials, assemblies, equipment, systems, plants and services become part of our products or directly or indirectly influence their quality. Requirements for goods, products and services to be procured must therefore be systematically planned, controlled, checked and constantly improved.
Evaluation criteria for the quality capability of suppliers are
- The technical quality of the products,
- the logistical quality of the deliveries,
- the communicative quality of the business partners and
- the commercial quality of the contracts.
This objective is a joint task of the procurement organisation with the suppliers and requires close cooperation, insofar as the type and scope of the orders require it, with appropriate organisational processes for both partners. Responsible suppliers strengthen their performance and the confidence of their customers by setting up and demonstrating an effective, up-to-date quality assurance system.
Quality requirements of products and services to be procured
The quality requirements are based on the requirements documents provided by the Procurement organisational unit, which clearly define the goods and services to be procured. Technical requirements can refer to standards, rules and regulations (DIN, ISO, VDE, UW, etc.) and are a contractual component of the quality requirement to be observed by the supplier. Requirements documents are - in the case of development, planning, execution by the supplier - also corresponding documents of the supplier himself. They require our approval and release. The supplier must ensure that planning, production and monitoring are always carried out in accordance with the latest valid documents.
Quality assurance systems and measures
With the contract, the supplier has assumed obligations and agreements in accordance with the statutory regulations. He has a significant influence on the quality of his delivered products and services and must also ensure a deviation-free delivery. He must therefore ensure by means of appropriate, suitable quality assurance systems and measures that the deliveries and services fully comply with the stipulated requirement profiles of the contract. The quality assurance system applied by the supplier or the measures introduced shall ensure that
- raw materials purchased from sub-suppliers are not processed or installed until they are in full compliance with the agreed requirement profile;
- any deviations occurring are quickly identified, appropriately analysed, corrective measures introduced and their effectiveness ensured;
- the contractual delivery and service meet all specified and agreed requirements.
Quality planning, inspections and records
In consultation with the supplier, the user and procurement staff define appropriate inspection plans, instructions and procedures to ensure that the quality requirements are met. Depending on the risk assessment of the purchaser, documented individual inspections, with associated characteristics according to inspection plans and instructions, or random sample inspection systems may be used. Records of the results of tests carried out can be agreed as evidence in the event of product liability. If required, proof of conformity, tool certificates and test certificates (e.g. according to DIN 50049) shall also be provided.
Delivery request
The agreed delivery dates, product and performance requirements must be complied with. Packed and ready-for-shipment deliveries are to be demonstrably released by corresponding responsible persons (production or quality managers) of the supplier. The supplier shall pack and inspect products appropriately and avoid transport damage and loss of use. If necessary, agreed special packaging requirements shall be observed. For the purpose of recording and processing incoming goods, each packing and delivery unit shall be provided with an externally visible identification showing the contents, number of pieces, order number and packing date. If further details are necessary, these shall be coordinated and agreed upon.
Audits
By means of agreed audits at the supplier's premises, the client or an authorised representative can, if necessary, inform himself about the type, scope and effectiveness of the quality assurance system and the supplier's measures.
Initial sample inspection and release
Prior to the commencement of series deliveries, initial samples shall be presented in good time for assessment and release in the following cases:
- for new parts and products, if agreed;
- in the case of changes to quality characteristics, tolerances and characteristic limits;
- in the case of the use of new or modified raw materials, technologies, tools, machines, plants and production facilities.
The samples must be representative and the quality capability of all material and application characteristics must be tested and documented by initial sample test reports and measurement sheets. The sample consignments shall be clearly and visibly marked "Sample". To ensure traceability and for comparison in case of disagreement, it is advisable to keep approved sample parts or modified samples in an appropriate place. Appropriate testing and release procedures may be agreed for products developed and produced by the supplier.
Duty to inform
Deviations and unilateral changes are not permitted without prior written approval.
Willingness to cooperate
The procurement organisations of Zwiesel Kristallglas AG are happy to discuss all issues arising in this context with suppliers and to provide support if required.
Incoming goods inspection
On receipt of goods, general and specific quality inspections are carried out according to sampling plans.
The inspection results of the delivery are taken into account in the supplier evaluation. If there is evidence that a documented quantitative and qualitative outgoing goods inspection is carried out at the suppliers, this is positively reflected in the supplier evaluation.
Supplier evaluation
The supplier evaluation provides information on the performance of individual suppliers and enables an objective comparison between several suppliers. Service, communication skills, product quality, pricing policy, delivery reliability, logistics, environmental and energy management are recorded and evaluated.
Environmental policy of Zwiesel Kristallglas AG
Our aim is to implement environmental protection in a continuous improvement process as an integral part of all corporate activities and to prevent environmental damage. Compliance with legal regulations and official requirements is a matter of course for us and is subject to permanent monitoring.
Our corporate goal is also to reconcile environmental protection and economic efficiency. To achieve this, we need the commitment of all our employees. We strengthen them through training and by giving them independence and responsibility. Managers therefore play a special role as role models.
Environmental management
Zwiesel Kristallglas AG strives to avoid negative effects of its products on people and the environment wherever possible. The supplier must set up and maintain an efficient environmental management system to achieve this goal. The procurement department will be pleased to answer any questions that may arise in this context.

We communicate this commitment throughout the company. We review them regularly and adapt them to new situations as necessary.
Energy management
We remind our suppliers that an evaluation of products, facilities and services that have a significant impact on our energy use is based in part on energy-related performance.
In this respect, we expect active support from our suppliers with regard to a possible optimisation of our energy use and energy consumption, as well as our energy efficiency over the planned useful life of the required energy-using products, facilities and services.
