ISO là tên viết tắt của Tổ chức Quốc tế về tiêu chuẩn hoá (International Organization for Standardization), được thành lập vào năm 1946 và chính thức hoạt động vào ngày 23021947, nhằm mục đích xây dựng các tiêu chuẩn về sản xuất, thương mại và thông tin. ISO có trụ sở ở Geneva (Thụy Sĩ) và là một tổ chức Quốc tế chuyên ngành có các thành viên là các cơ quan tiêu chuẩn Quốc gia của hơn 150 nước. Việt Nam gia nhập ISO vào năm 1977, là thành viên thứ 77 của tổ chức này. Tuỳ theo từng nước, mức độ tham gia xây dựng các tiêu chuẩn ISO có khác nhau. Ở một số nước, tổ chức tiêu chuẩn hoá là các cơ quan chính thức hay bán chính thức của Chính phủ. Tại Việt Nam, tổ chức tiêu chuẩn hoá là Tổng cục Tiêu chuẩn Đo lường Chất lượng, thuộc Bộ Khoa học và Công nghệ. Mục đích của các tiêu chuẩn ISO là tạo điều kiện cho các hoạt động trao đổi hàng hoá và dịch vụ trên toàn cầu trở nên dễ dàng, tiện dụng hơn và đạt được hiệu quả. Tất cả các tiêu chuẩn do ISO đặt ra đều có tính chất tự nguyện. Tuy nhiên, thường các nước chấp nhận tiêu chuẩn ISO và coi nó có tính chất bắt buộc. Có nhiều loại ISO: Hiện nay hệ thống quản lý chất lượng ISO 9001:2000 đã phát hành đến phiên bản thứ 4: ISO 9000 (1987), ISO 9000 (1994), ISO 9001 (2000), ISO 9001 (2008) Ngoài ra còn nhiều loại khác như: ISO14001:2004 Hệ thống quản lý môi trường. OHSAS18001:1999 Hệ thống quản lý vệ sinh và an toàn công việc. SA 8000:2001 Hệ thống quản lý trách nhiệm xã hội
