Product and Service Quality Assurance

Quality Policy

We provide environmental testing devices used by our customers in their QA(QUALITY ASSURANCE) activities. As such, the quality of our products is directly linked to the quality of their products, and we feel that this heavy responsibility represents why we are in business. Based on our basic philosophy to “provide more reliable products and services that allow our customers to safely, comfortably, and surely fulfill the mission,” we at ESPEC work towards creating high-quality products that meet the expectations of our global customers.

• Quality Assurance (About ESPEC)

Quality Assurance System

We have established a unique system we called EQA (ESPEC QUALITY ASSURANCE) in Japan and overseas.
In 1993, we were also assessed for and obtained the ISO 9001 (international standard of quality management) certification ahead of the competition. In FY2024, we received a “Special Long-Term Certification Award for Management System Registration” from the JSA Solutions Co., LTD., recognizing 30 years of continuous registration under ISO 9001. We continued to strengthen quality assurance activities to improve work process levels and enhance product and service quality.

QC circle activities

ESPEC engages in QC circle activities focused on frontlines production sites. Our policy is to “use QC circle activities to achieve targets and resolve problems and issues,” and in FY 2024, there were 29 circles that engaged in improvement activities on a variety of topics. These efforts produced a high level of results including quality improvements, cost reductions, and operational efficiency improvements while also contributing to personnel training.

Improving Customer Satisfaction

Start of “Aichi Next-Generation Mobility Test Lab” service

As part of the “Aichi Next-Generation Mobility Test Lab” initiative, we opened one of Japan's largest specialized testing facilities for automotive batteries, the “Aichi Battery Safety Testing Center” (Tokoname City, Aichi Prefecture), in February 2025, and expanded the functions of the “Toyota Test Center” (Toyota City, Aichi Prefecture), ESPEC's largest integrated testing facility, in April. These initiatives strengthen our contract testing services for automotive batteries and EV/automation modules primarily in the Chubu region, contributing to the safety and reliability of next-generation mobility.

The 4 Promises of our After-sales Service System for Safety and Security

So that customers can use our products with complete peace of mind, we provide after-sales service based on the following 4 Promises.

Added network functionality in standard maintenance contract services

In September 2023, we added mobile device/cloud network functionality to our maintenance contract services as a standard menu item. With network functions, it is possible to monitor and control chamber operating conditions even from a remote office or home. When an error occurs in a chamber, the customer is notified by email and at the same time ESPEC also detects the error and provides support for rapid chamber recovery by means such as remote diagnosis. In addition, by providing mobile communication devices equipped with SIM cards, we reduce the need for customers to connect to internal networks or install LAN equipment, thereby easing system implementation burdens. We save our customers the hassle of chamber management through digital transformation of chamber management tasks and preventive maintenance service (annual inspection and replacement of worn parts) to ensure reliable chamber operation and fixed repair fees.

Comprehensive support for customer facilities
"Comprehensive on-site maintenance service"

Beyond maintenance and servicing, we provide "comprehensive on-site maintenance services", which support the entire lifecycle of environmental test chambers, from installation of equipment and peripherals to fluorocarbon recovery and product recycling (disposal). We make chamber management easier for our customers and help optimize their maintenance and operating costs.

After-sales service certification system

We have introduced a new after-sales service certification system based on global common evaluation standards in order to train service engineers equipped with advanced specialized technical skills. It can be used not only by ESPEC service engineers but also by service engineers at distributors and cooperating companies in order to standardize and improve the level of service. We also conduct renewal testing every three years to ensure that our service levels remain current and of the highest standard.

Customer Support Desk

We have set up the Customer Support Desk as a system that provides one-stop solutions for issues arising in all types of scenes, from product purchasing to product disposal. It allows us to directly respond to a range of customer inquiries. To further enhance information availability on our website and improve customer service quality, we have newly introduced an IVR (interactive voice response) system. In addition to we also conduct regular internal training on proper phone service and product knowledge, so we can keep improving the quality of our customer response.

Improving usability of the product information page on our website

We have added functions to our product information page to enable customers to quickly access frequently requested information. The page also features numerous customization examples of products optimized for various testing standards and requirements, earning positive feedback from customers.

Held sponsored lecture at xEV Testing Initiative

In October 2024, we held a lecture at xEV Testing Initiative, Japan’s only business conference on the quality, safety, and reliability of electric vehicles. Sponsored by ESPEC, the conference is organized by the Steering Committee for xEV Testing Technology, which is vice-chaired by Noboru Sato, Executive Advisor to ESPEC and a visiting professor at the Institute of Innovation for Future Society of Nagoya University. In Presentations, we introduced “Safety Testing for Automotive Batteries.”

ESPEC Reliability Seminar

As part of our initiatives to provide valuable information on reliability testing to customers, we hold an annual Reliability Seminar. In FY2024, the seminar was conducted online (webinar format) under the theme “Latest Testing and Evaluation of Secondary Batteries and Compliance with the EU Battery Regulation,” with approximately 300 customers participating.

Website for engineers, "Test Navi"

We have developed a website specializedin information on reliability technology for engineers called "Test Navi."It gives customers helpful information in practice settings, such as environmental testing knowledge, basic information on reliability technology, and the latest testing trends, at the appropriate timing. The number of members registered with "Test Navi" currently exceeds 24,000.
