JIS Summary Reports

The following sections will provide JIS certification data from various summary reports, including the Factory Name Lists of 1955 and 1958, the Certified Lists of 1962, 1964, 1967, 1972, and 1982, and a web-based summary from 1999.

In general, the summary reports provided the cumulative certification status for companies that remained certified at the time of the report.

Prior to 1971 the summary reports served as the only source for product notes, including the notes that defined the class suffixes "N", "H", "P", and "S". The product notes should have been published in the JIS Monthly Reports, so that an association with the test date could be established, but for unknown reasons this was delayed until 1971.

1955 JIS Factory Name List

Fig. 30. Cover of 1955 JIS Factory Name List.

In 1955 the JIS administration published the first edition of the JIS工場名簿, commonly translated as the "JIS Factory Name List". This publication was a directory of all factories with JIS certifications for a wide range of product classes.

The scan in Fig. 30 shows the cover of the 1955 Factory Name List, as published by the Japanese Standards Association.

As might be expected for a first edition, there are some limitations in the data presented. In particular, the test dates for the certifications are omitted, and there are no notes such as jaw angle or "heavy" grade to describe the tested products.

We have extracted scans from the 1955 Factory Name List for classes B4604/B4606, B4614, B4623-B4625, B4630, and B4631, which are presented in the figures below.

1955 JIS Summary for Classes B4604 and B4606

Fig. 31. JIS Classes B4604 and B4606 from 1955 Factory Name List.

The scan in Fig. 31 shows the JIS certifications for Classes B4604 (adjustable wrenches) and B4606 (pipe wrenches), as published on page 37 of the 1955 Factory Name List.

This report omits the dates of the certifications, and although the JIS class is specified, no further notes are provided.

The table below shows an approximate conversion of the above scan into Japanese text, with headers added for convenience. We have also added the test date known from other reports.

Comments on JIS 1955 Class B4604 and B4606 Data

• The Showa era date known from other reports has been added for convenience.

1962 JIS Certified List

Fig. 45. Cover of 1962 JIS Certified List.

In 1962 the Japanese Standards Association published the first JIS表示許可工場名簿 or "List of Factories Approved for JIS Certification". As with the previous Factory Name Lists, this was a directory of the factories with JIS certification in effect at the time.

For brevity we will refer to these reports as the "Certified List" in the particular year.

The scan in Fig. 45 shows the cover of the 1962 Certified List, as published by the Japanese Standards Association.

The 1962 Certified List was a substantial improvement over the previous summary publications, as it included the dates for the certifications and provided notes describing the tested products.

Comments on JIS 1964 Class B4604 and B4606 Data

• The earliest date in the table is for Showa 26, corresponding to 1951. (Add 1925 to convert Showa dates.)
• Comparison with the 1962 Certified List shows that JIS number 655 (Sanjo Machinery) is no longer included.
• The entry for JIS 1447 has "230形" in the notes, an obvious typo for "23°形".
• The company name for JIS number 656 has changed from Nakajima Precision Forging in the 1962 report to TOP Kōgyō, and the date has changed from 26.6.28 to 38.1.28. More surprisingly, the footnote ② indicates pipe wrenches, but also mentions normal and strong grades and a 23 degree angle, which are typical specs for adjustable wrenches. We think this is an error and have corrected it to ① .
• The company name for JIS number 1449 has changed from "Shin Mitsubishi-den Kōgyō" in the 1955 report to just "Mitsubishi Den Kōgyō", but the factory name is the same.
• The company name for JIS number 2722 is now correctly listed as "Shin Sanda Kōgyō".
• The entry for JIS number 658 (Nippon Riki) has a footnote ② indicating pipe wrenches in both normal and strong grade, fully forged, and a 23° angle. We have reordered the notes to show that the fully forged and 23° angle attributes apply to ① adjustable wrenches.
• For JIS 2356 the 29.1.30 date in the scan is incorrect and has been corrected to 28.6.20.
• The certifications in the above table have all been entered into the JIS database.

1982 JIS Certified List

The 1982 JIS Certified List was published with a very serious deficiency in that the product notes were omitted. The loss of the product notes is most serious in the case of reports covering multiple product classes, as the classes applying to a particular company are supposed to be identified by numbered circles in the notes field. Ironically a number of the reports supply a key in the heading with numbered circles for the JIS classes, but since the notes were omitted we don't even know which classes apply!

In an attempt to salvage some utility from the 1982 report, we have copied the notes field from the 1972 report, but this will obviously overlook any changes that might have occurred in the decade between the reports.

The 1982 published reports include the Japanese postal code as the fourth column of the tables, but since this is not relevant for our application, it has been omitted from our OCR conversions.

1999 JIS Summary Website Archive

In 1999 the JISC website published the JIS certifications in effect at that time, at least for a brief time. But it was long enough for the pages to be archived, and as a result we have online access to this data. We'll refer to this resource as the 1999 JIS Summary.

This data is much easier to work with for us — since everything is already in machine-readable text, no OCR conversion step was necessary.

The 1999 data is organized somewhat differently than the earlier reports. In particular, the data is broken out by reporting region, and no footnotes are provided to indicate the product characteristics (e.g. strong grade).

In addition, the data is grouped by a product super-class combining several JIS classes.

Since the reporting region is not relevant for our purposes, we have folded all of the regions into one table.

The following link has the 1999 Summary (in Japanese).

• JIS Classes [External Link]

1999 Summary for Super-Class B010 (Pliers)

The 1999 Summary provides data for various types of pliers in super-class B010, consisting of JIS classes B4623, B4625, B4631, and B4635 in this sample.

The data in the table below was extracted from the website archive, with minor edits for presentation.

• The certifications in the above table have all been entered into the JIS database.

1999 Summary for Super-Class B013 (Wrenches)

The 1999 Summary groups JIS classes B4604 and B4606 (adjustable and pipe wrenches) under the B013 super-class.

The data in the table below was extracted from the website archive, with minor edits for presentation.

Comments on JIS 1999 Summary for Class B4604 and B4606 Data

• Note that JIS number 657 for Toho Kōki is listed on 1985-06-13 with class B4606, but not with class B4604. Both classes B4604 and B4606 are known to have been re-registered on this date after a factory move, and the B4604 registration was later released on 2000-07-12. The absence of B4604 in this report may indicate that the registration had been suspended some time before its eventual release.
• The certifications in the above table have all been entered into the JIS database.

1999 Report for Super-Class B027 (Fixed Wrenches)

The 1999 Summary provides data for several types of fixed wrenches in super-class B027, which covers JIS classes B4630 (open-end wrenches), B4632 (box-end wrenches), and B4651 (combination wrenches).

The data in the table below was extracted from the website archive, with minor edits for presentation.

Comments on JIS 1999 Summary for Super-Class B027

• JIS 364147 (Hokuyo Sangyō) for class B4630 was cancelled on February 17, 1993, but has magically come back to life in this report. We think that what happened was that 369042 had been revoked in the early 1990s and then reassigned to JIS 364147, as part of the JIS consolidations occurring around that time. Then when certificate 364147 for B4630 was cancelled in 1993, it left 364147 still applying to B4632.
• The certifications in the above table have all been entered into the JIS database.

1999 Report for Super-Class B043 (Combination Pliers)

The 1999 Summary provides data for combination pliers in super-class B043, consisting of just JIS class B4614 in this sample.

The data in the table below was extracted from the website archive, with minor edits for presentation.

1999 Report for Super-Class B070 (Waterpump Pliers)

The 1999 Summary data in super-class B070 includes JIS class B4626 (waterpump pliers). This is actually the first summary report to include class B4626.

The data in the table below was extracted from the website archive, with minor edits for presentation.

• The certifications in the above table have all been entered into the JIS database.

1999 Report for Super-Class B072 (Socket Wrenches)

The 1999 Summary provides data for socket wrenches in super-class B072, which consists of JIS classes B4636-1 and 00225 in this sample.

The oddball class 00225 needs some explanation. In 1998 the JIS standards for socket wrenches were revised to classify tools based only on drive size, using class B4636-1 for 12.7mm square drive and class B4636-2 for other square drive sizes from 6.3 to 25mm. Prior to 1998 socket tools had been tested based on functional groups (sockets, ratchets, extensions, etc.) without regard to drive size, and apparently some of the prior tests that couldn't be grouped into the new classes were placed in 00225 instead.

The data in the table below was extracted from the website archive, with minor edits for presentation.

Comments on JIS 1999 Summary for Super-Class B072 Data

• The inclusion of JIS number 4248 (Maeda) in class B4636-1 at Fukae would be for old classes B4637 and B4639, which continued after B4636 was canceled on June 17, 1985. See the 1985-10 Monthly Report for details.

1999 Report for Super-Class B090 (Bolt Cutters)

The 1999 Summary data in super-class B090 includes JIS class B4643 (bolt cutters).
