Quality Policy

Providing Safe, High-Quality Products and Services

With this in mind, Daikin strives to stay ahead of customer needs by providing high-quality products and services based on its corporate policies of "Absolute Credibility," "Enterprising Management," and "Harmonious Personal Relations."

With a quality management system in place, we ensure that our products are of the highest levels of safety and quality in all processes: from design and manufacture to sales and after-sales service.

Quality Policy in the Divisions

Air conditioning divisions: "Provide high-quality products through relentless improvement activities."
Service divisions: "Achieve the highest level of service quality (in speed, accuracy, and politeness)."
Chemicals divisions: "Provide quality that sells and that satisfies customers' demands."

Product Quality Management Structure

Thorough Management in Development, Procurement, and Production

All major manufacturing bases in Daikin are ISO 9001-compliant and have quality assurance systems conforming to this international standard. Company divisions maintain high levels of product quality and ensure proper management of each department, such as development, parts procurement, and production. We are also improving quality at our contract manufacturers.

Improving Quality

Only Those Products That Pass Our Strict Design Review for Product Safety Are Manufactured

The air conditioning divisions have reformed their development process with a stricter, more segmented design review* under which the personnel in charge of the development divisions inspect the proposed products for conformity to Daikin standards using the four criteria of an individual design review (DR): product quality, monotsukuri (the art of manufacturing), cost-effectiveness, and compliance. The same design review is conducted at Daikin's overseas bases.

In the Chemicals Division, we have been conducting reviews based on a four-level management system consisting of development theme verification, technology establishment, business-viability establishment, and mass-productivity. As key review standards, in addition to the four criteria of product quality, monotsukuri (the art of manufacturing), cost-effectiveness, and compliance, we focus on safety and environmental consciousness. In fiscal 2015, because we cannot get evaluations from customers and the industry with regards to criteria in the stage of business-viability establishment, we increased the number of inspections we do to strengthen design review functionality.

* Design review: In a process involving the entire Daikin organization, products under development are assessed for quality of design and all other processes leading up to product realization. Only those that pass each stage can move forward.

Example of Quality Improvement in Development: Forced Fire Test Conducted in Combustion Test Room

During the development stage, actual products are used to ensure that even if an accident occurs due to a faulty product the problem does not spread beyond the product itself.

Example of Quality Improvement in Development: Global Product Structural Audit

Every two years, Daikin holds a meeting of the Global Product Structural Audit. With participation by quality control managers from production bases, the goal is to share know-how and bring together those working on the front lines of quality so as to ensure that Daikin's product structural auditing is conducted at the highest possible level worldwide. In fiscal 2016, the meeting focused on reviewing the number of defects inherent in products, the use of tools and equipment, and improving auditing of factors such as work safety.

Tracking Customer Information and Product Information

We have two global systems for gathering information—on customers and products—from markets around the world. The information is used to solve problems at each base and thus create better products.

Establishing Protocol for Promptly Handling Product Accidents

Daikin products are designed based on quality standards and design standards that ensure that, even if users err in operating the machinery or use it beyond recommended limits, there is no danger for the users; and even if there is a product accident, the danger to the user is minimized.
In case of a product accident, we have systems in place that allow us to quickly relay the necessary information and handle the problem, and minimize the impact on the product users and the general public.

We also place top priority on detecting product problems before they lead to a major accident. When the cause of a minor accident is discovered, we determine whether this could also cause a major accident and we reflect this into the development of future products. In fiscal 2017, there were no cases of product recall.

Policy on Product Safety

Product Safety Voluntary Action Guidelines

The Daikin Group (hereinafter, "the Group") believes that its most important management task is to provide products that satisfy customers from the standpoint of our customer when designing and making products that have a high level of safety and quality. To this end, we have formulated the following basic policies on product safety in efforts to provide ever-greater levels of safety and quality in products.

  1. Legal Compliance
    The Group shall observe the Consumer Product Safety Act and other product-related laws and safety standards.
  2. Ensuring Product Safety
    The Group shall establish a quality management system and execute measures to maintain product safety in all processes extending from product design to production, sales, and after sales service. And the Group shall display appropriate, easy-to-understand instructions and warnings on products and in instruction manuals to ensure the safe use of our products by our customers.
  3. Collecting and Providing Product Accident Information
    The Group shall actively collect information from our customers concerning accidents involving Daikin products and quickly report this information to our executive management while providing customers with suitable information.
  4. Immediate and Appropriate Response to Product Accidents
    In the unlikely event of a safety problem occurring in the use our product, our first and primary concern shall be for the safety of our customers, and we shall take immediate actions to minimize and prevent the occurrence of a serious accident. Actions to be taken immediately shall include repairing or replacing the product in question, publicizing the problem through the appropriate media, and submitting a statutory report on the problem to the relevant authorities. All relevant people outside the company, including sales company personnel, will be informed of the situation.
  5. Product Safety Promotion
    The Group shall establish a quality assurance system that it uses to ensure product safety and quality.

    The Group shall constantly make every effort to promote the safety and quality of our product through widespread education and training within the company in laws and regulations on product safety. We also shall regularly monitor work to ensure product safety is being achieved.

(Formulated in June 2007)

Global Product Safety Standards

We have formulated our Global Product Safety Standards to ensure products are designed for the utmost safety by having standards common to all Daikin worldwide bases. The goal is to make sure that products can be operated safely and that damage is limited to the absolute minimum in case of a product accident—whether the customer is using the product correctly or incorrectly.

These safety standards set common rules for the global Daikin Group regarding things like fire, electrical shock, and explosion, and stipulate two layers of safety in the design: design that will prevent accidents from occurring, and design that will minimize damage should an accident occur.

Efforts to Ensure Safety

Clear and Concise Product Use Instructions

The Consumer Product Safety Act obligates companies to design products for safety and provide consumers with information and warnings so that household product accidents can be avoided.

Based on the failsafe* philosophy, Daikin's system of checks ensures that customer safety is the top priority in design and that design review (DR) leads to safe products.

Our website also provides consumers with information including the model number and production year of products already on the market. In April 2009, the Ministerial Ordinance of technical standards for the Electrical Appliance and Material Safety Law went into effect. We abide by this ordinance by placing labels on our residential air conditioners and ventilation fans (which are covered by this law) that state the duration of product use.

* Failsafe: Checks and measures are in place to ensure safety in case of a breakdown of mechanisms or systems.

User Manuals Available Online

In Japan, about one-third of the product accidents are the result of improper product operation. We therefore strive to provide customers with accurate, easy-to-understand operating instructions so that they can use our products safely.

The air conditioning divisions conduct product labeling in compliance with industry guidelines, such as the Guidelines for Labeling Household Products for Safe Use (5th edition, revised October 2015), published by the Association for Electric Home Appliances, and the Revisions Labeling Procedures (March 2010), published by the Japan Refrigeration and Air Conditioning Industry Association.

When we make product user manuals, we make sure they are readable, easy to understand, and easily searchable. This ensures that customers can use products with peace of mind. We work with our design, quality control, service, and sales departments to improve areas of customer confusion in order to make manuals with which customers can get the answers they need quickly.

For the installation product user manual of commercial air conditioners developed in fiscal 2014, we changed the page size from A1 to A4 to make the text easier to read. For wired remote controllers launched in April 2017, users can easily download the manual from our website by smartphone or computer.
