Assuring high quality and safety
through strict inspections by our in-ho laboratory
To assure high quality and safety, we have set up an in-house laboratory where we carry out strict inspections complying with JIS and ISO standards for conditions such as durability and color fading. By internalizing inspections rather than entrusting them to an outside agency, we can achieve speedy quality checks for newly developed products from Japanese and foreign manufacturers. This enables quick supply. We believe this to be the value we provide through acting as an intermediary trading company.
Passion for quality
Shimada Shoji has been certified as a testing location that conforms to the requirements of ISO/IEC 17025, a standard set by the International Organization for Standardization and the International Electrotechnical Commision, and was registered as a testing operator under the JNLA system in May 2018.
JNLA is the abbreviation for Japan National Laboratory Accreditation System. It is a program under which the national government examines whether testing operators have the technical capabilities needed to conduct JIS testing appropriately and registers those that do. Registered testing operators can issue testing certificates with the JNLA logo as proof of their registration.
We strive to supply products with performances that have been proved to be highly reliable by testing under the JNLA system.
Corporations are increasingly being called upon to conduct their business in an environmentally friendly manner. In March 2001, as part of Shimada Shoji’s efforts to be a responsible manufacturer, the company had its head office certified under the ISO 14001 environmental management standard. In cooperation with affiliates, business partners, and suppliers, Shimada Shoji has striven to develop and offer environmentally friendly products, save energy and resources, implement green procurement, reduce and separate waste, and protect the environment surrounding our sites and those of our partner factories.
The laboratory that supports quality
We evaluate the degree of discoloration and fading of a material due to the action of light (ultraviolet rays) while being worn and while being dried outside after washing.
We evaluate the degree of discoloration and fading of dyed fabrics and accessories and their contamination to other fibers as a result of home laundering.
We evaluate the degree of discoloration and fading of a material, and contamination to other fibers during long periods of wear when wet with sweat.
We evaluate the degree of discoloration and fading of a material, and contamination to other fibers during long periods of wear when wet with water.
We evaluate the degree of contamination to other clothing items caused by the friction of cloth and small accessories during wear.
We evaluate the degree of contamination to other overlapping fabrics during long-term storage at high temperatures.
We evaluate the degree of transfer from dark sections to white or light sections in products with stripes or combinations of different colors and shades.
We investigate stretching and shrinkage, and changes in appearance of fabrics due to steam and heat from pressing.
We evaluate the degree of stretching and shrinkage of fabrics when immersed in water or detergent at a constant temperature.
We investigate stretching and shrinkage of fabrics due to liquids and mechanical force in conventional household washing machines.
We evaluate stretching and shrinkage, and changes in appearance of fabrics due to home laundering and drying, corresponding to the new JIS L0001 standard.
We evaluate the peel resistance of transfers. We can repeat laundering up to 99 times.
We evaluate stretching and shrinkage, and changes in appearance of fabrics due to home laundering and drying, corresponding to international standards (ISO).
We set a period and investigate the aging of the product in an environment at a temperature of 70°C and humidity of 95% or higher.
We investigate the content of heavy metals (mainly lead and nickel), which are harmful to humans, by X-ray irradiation.
We evaluate whether fabrics will tear during wear and their strength when torn horizontally and vertically.
We evaluate whether knitted materials tear easily during wear and their strength.
We evaluate the occurrence of pilling on the fabric surface due to friction during wear and laundering.
We evaluate the occurrence of protrusions, pulls and loops in fabric threads due to snags on protrusions.
We evaluate the degree to which seams split, seam allowances come out and the like when force is applied to textile seams.
We investigate the strength of pull cords and the strength at which the tip part at the end comes out.
We investigate the compression strength when pressure is applied to buttons when pressing or the like.
We investigate the strength of lead against impact when an impact is applied to buttons during wear and when tumble drying.
We evaluate the peel resistance of transfers, decals, bonding materials, etc.
