Japanese Industrial Standards specifies the standards used for industrial activities in Japan. The standardization process is coordinated by Japanese Industrial Standards Committee and published through Japanese Standards Association. The Industrial Standardization Law was revised in 2004 and the JIS mark product certification system was changed. Standards are named like “JIS X 0208:1997″, where X denotes area division, followed by four digits (or five digits for some of the standards corresponding ISO standards) and the revision release year. G – Ferrous Materials and Metallurgy H – Nonferrous Materials and Metallurgy MTC IN EN 10204.3 EN 10204:2004 is for metallic products-and this norm tell us things about Types of inspection documents. There are no material standards. Mostly material is defined with its chemical composition and mechanical properties in a public standars like ISO, EN, JIS, ASTM etc. What is JIS? Japanese Industrial Standards (JIS) specifies the

American National pipe (NPT, NPS), Like British Standard Pipe (BSP), is designated by trade size, rather than actual diameter, as shown in the table below. NPT Thread – American Standard Taper Pipe Thread (ANSI/ASME B1.20.1), Taper 1:16 Thread Form Data – Basic Dimensions of American National Standard Taper Threads, NPT (National Pipe Tapered) There are two basic types of National pipe threads: NPT: National Pipe Taper NPS: National Pipe Straight NPT threads are also sometimes referred to as MIP (Male Iron Pipe) FIP (Female Iron Pipe) IPT (Iron Pipe Thread) FPT (Female Pipe Thread) MPT (Male Pipe Thread) Note that these references are somewhat casual, and might possibly be used in reference to NPS instead of NPT. Both NPT and NPS have the same thread angle, shape, and pitch (threads per inch). However, NPT threads are tapered and NPS threads are straight (parallel). Both threads have a 60° included angle and have flat peaks and valleys (this is a Sellers thread
