The standards for
LONGTIME® certification process

The criteria of version 2 of the LONGTIME® certification are the result of two years of consultation and continuous development. The LONGTIME® V2 framework is built around three core pillars and now includes 38 control criteria, offering a broader and more in-depth approach to durability: reliability, repairability, and product lifecycle. Aside from minor updates, the framework is intended to remain valid for a period of five years, with its next revision scheduled for 2030

The basic criteria for LONGTIME® certification

The following criteria define a working base that is systematically supplemented and adapted to the specific characteristics of each product category. They are available for information purposes, but do not contain all the sub-criteria applicable to the various categories of certified products. For further details, please consult the sector-specific standards available on the LONGTIME® label website.

01

The product is robust and reliable

1 – Resistance to stress
The manufacturer identifies the functions of the product and its parts, as well as the critical usage constraints. They demonstrate sustainable design choices, optimised through reliability and/or repairability strategies.
2 – Production chain
The manufacturer demonstrates processes enabling him to control and maintain consistently high manufacturing and assembly quality in the production phase.

3– Logistics
The manufacturer reduces risks to the reliability of components and assemblies through effective quality processes for managing supply, packaging, storage, handling and transport conditions.

4 –Supply chain
Within its value chain, the producer details the performance of its quality management linked to the reliability of its suppliers’ goods or services directly related to its manufacturing phases.

5 – Reliability plan
The producer provides a history of product versions and identifies the changes implemented to improve product durability.

6 – Disruptive technology
The manufacturer provides information on the proportion of disruptive technology embodied in the product and identifies the functions associated with it. He demonstrates the reliability of this technology, especially if it concerns a primary function.

7 – Failure rate
The producer monitors actual failure rates and/or indicators by product part in order to monitor product reliability at least until the last unit of the model concerned is put on the market.

8 – Product identification
The manufacturer uses a method that allows unequivocal identification of the product and its version by interested parties in order to maximize maintenance and failure management processes.

9 – Completeness of user information
The manufacturer publishes a manual detailing the product’s use and maintenance instructions, and provides the user with a maintenance plan. This information, which is also available online, must be exhaustive and relevant in order to reduce exogenous failure rates and encourage responsible use.

10 – Format of user information
The manufacturer produces a clear, simple and accessible user and maintenance advice booklet (font size, vocabulary, language and print quality), so that it can be easily understood by end-users.

11- Prolonged immobilization
The manufacturer identifies the risks of failure associated with prolonged immobilization of the product. It informs the end user of the conditions of use necessary to prevent these risks.

02

18 – Availability time for spare parts
The availability time for spare parts is at least equal to the expected service life of the product category and its various parts. The availability time is assessed from the time the last unit of the model concerned is put on the market.

19 – Accessibility of spare parts to target groups
The producer ensures that spare parts are made available to the target groups normally suited to the category of parts.

20 – Terms and conditions for the sale of spare parts
The manufacturer details the terms of sale of its spare parts. They reflect the product nomenclature and are not sold as a group unless this is justified by coherent and verifiable design, calibration and/or economic reasons.

21 – Price of spare parts
The value of a spare part must not exceed a maximum percentage of the recommended selling price excluding VAT. A tolerance is allowed for parts whose RRP exceeds the specified percentage.

22 – Cost of transporting spare parts
The producer delivers the spare parts at the actual cost of dispatch and preparation or proposes alternative solutions reducing the cost of receiving the parts.

23 – Delivery time for spare parts
The producer demonstrates its ability to supply spare parts to interested parties in less than 5 working days.

24 – Documentation relating to failure scenarios
The manufacturer makes available relevant information and instructions relating to the resolution of failure scenarios and/or the implementation of the maintenance plan. These are also adapted to the product category and target audience. The minimum period of availability of information is specified in the sector-specific standards.

25 – Support for fault diagnosis

26 – Resetting settings and passwords
In the event of repair or transfer to a third party, the product has processes for managing user data to enable efficient and secure re-use.

27 – Software
The manufacturer shall ensure that the original performance of its product is maintained when updating the operating system and/or firmware and shall differentiate between upgrades and corrective updates. The user is informed of the consequences of updates and his/her consent is required.

28 – Internal failure resolution policy
In the event of product failure, the producer shall pursue a policy of repair or reconditioning rather than replacement, unless repair is more expensive than replacement, taking into account the wishes of users.

29 – After-sales service contact
The producer demonstrates that the opening of an after-sales service file does not exceed 2 working days.

30 – Return services
The manufacturer provides end-users with return services adapted to the product category and consistent with its distribution network, regardless of the status of warranties.

31 – Condition of return
The return of the original packaging cannot be required for the repair of a product once it has been packaged and protected to the extent that it could have been at the time of purchase.

32 – High-utility products
In its network and for product categories considered “high-utility”, the producer reduces the repair process time as much as possible, until the product is returned to the end user.

33 – Warranty period
The warranty period with presumption of anteriority of the defect may not be less than 24 months.

34 – Warranty exclusions

LONGTIME® sectoral certification standards

The LONGTIME® certification standards have been developed to meet the growing need for reliable, repairable and eco-designed products in a context where responsible consumption is becoming a global priority.

The LONGTIME® standards are based on a consultation process with stakeholders. Thanks to an approach based on precise control criteria, they make it possible to assess the long-term sustainability of products, taking into account their environmental impact at every stage of the life cycle.

Designed to be applied to a wide range of products, from domestic appliances to professional equipment, the LONGTIME® sector standards aim to promote a different kind of consumption, based on the conservation of resources and the reduction of waste.
