Detailed Information

Scope	This standard covers the performance requirements of tube fittings used by being connected with polyamide tubes specified in JASO M 317 or other thermoplastics air brake tubes (hereinafter collectively referred to as “tubes”), and assembles of such tubes and tube fittings that are connected together (hereinafter referred to as “tube assemblies”). This standard is also applicable to devices and circuits that use compressed air in the same system as the air brake. Table 1 shows the maximum working pressures (hereinafter referred to as “gauge pressures”) and working temperature ranges of tube assemblies. NOTE: The tube assemblies are classified into four categories of specifications based on the maximum working pressure and working temperature range. This standard defines the requirements of each of the categories.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.
