NF S86-606
NF S86-606 is a French horology standard stating test methods for leather and soft watch straps employed in wristwatches. The standard outlines the approach to testing watch straps for mechanical performance, durability, and resistance, with conditions that mimic real-life wear. Watch straps are more susceptible to repeated bending and pulling, as well as fingerprint oils and dirt that wearers will touch daily; a strand that keeps up its strength and appearance with time is what is needed. NF S86-606 assists manufacturers to ensure that a soft watch strap that they manufacture conforms to the specified quality requirements and will satisfy the requirements of normal use without undue failure.
Significance
The impact of NF S86-606 is in its ability to build trust, confidence, and quality in the products in the watch industry. Constant forces of flex and tensile are being applied to the leather and soft watch straps when fastened, adjusted, and moved regularly. If materials are too weak or construction is not very good, very important parts of the straps may tear, stretch, or fail. Manufacturers can determine the performance of a strap before it makes it to the market following the testing guidelines set forth in this standard. The standard facilitates quality control programs, product development activities, and consistency in product manufacturing. Compliance with NF S86-606 helps brands deliver watch straps that offer long service life, comfort, and dependable performance. Scope NF S86-606 covers test methods for leather and soft watch straps used in horological products. It involves properties such as mechanical properties, repeated stress resistance, fastenability, and durability. The standard relates to the watch companies, strap producers, test laboratories, and quality assurance departments tasked with enforcing the performance and durability of soft materials and assemblies of watches.
