1. Scope

This Japanese Industrial standard specifies fittings for use in the connection
of crosslinked polyethylene pipes (hereafter referred to as pipes) specified in
JIS K 6769, herafter referred to as fittings.

Remarks 1. The following standards are cited in this Standard.

JIS B 0202-Parallel pipe threads

JIS B 0203-Taper pipe threads

JIS B 1002-Dimensions of width across flats

JIS K 6769-Crosslinked polyethylene (XPE) pipes

2. Those units and numerical values shown in braces { }

in this Standard are based on the traditional metric system
of units and are shown for reference.

2. Classification

Fittings shall be classified as in Table 1 according to the kind of pipe,

kind by shape, and kind by construction. However, fittings of other kinds and
constructions than shown in Table 1 may be used by agreement between the
parties concerned if they meet the requirements of 3.

5. Test methods

5.1 Low water pressure test Connect a pipe 250 mm or longer in length
to the fitting, then apply to the inside a pressure of 0.0196 MPa {0.2 kgf/cm2}
by water at room temperature, leave it standing for 2 min. and examine
for the occurrence of leakage and other defects.
5.2 High water pressure test Connect a pipe 250 mm or longer in length
to the fitting, then apply to the inside a pressure of 2.45 MPa {25.0 kgf/cm2}
by water at room temperature, leave it standing for 2 min. and examine
for the occurrence of leakage and other defects.

5.3 Hot internal pressure test Fill a specimen similar to that used in the
water pressure tests with warm water, air, or nitrogen, and after conditioning
the specimen at 95 ± 2°C for one hour or longer, apply the pressure of Table 5,
keep the same condition for one hour, and examine for the occurrence of leakage
and other defects. The test temperature shall be 95 ± 2°C.

tion for one hour, and examine for the occurrence of slipping out or other
defects •

6. Inspection
The inspection of fittings shall be classified into the type inspection( 3).
and delivery inspection ( ~), and tests shall be performed for the undermentioned
items and the results shall meet the requirements of 3. and 4.
The sampling inspection method in the delivery inspection shall be
decided by agreement between the parties concerned.
Notes (3) An inspection for judging whether the quality of the product
satisfies all the design characteristics.
(4) At the time of delivery of products produced by the same
design and the same production method as the product already
accepted in the type inspection, an inspection for jlJ,dging
whether the products satisfy the characteristics recognized as
necessary.
(1) Type inspection

(a) Appearance, shape, and dimensions inspection.

(b) Low water pressure inspection.
(c) High water pressure inspection.
(d) Hot internal pressure inspection.
( e) Pull- ol,l t insp ection •

( 2) Delivery inspection
(a) Appearance, shape, and dimensions inspection.

(b) High water pressure inspection.

7. Method of designating products

Fittings shall be designated by the number or title of the standard, kind of

pipe, kind by shape, kind by construction, and nominal diameter.

Example 1. JIS B 2354 PN 10 adaptor flange type 20

Example 2. Crosslinked polyethylene pipe clamp type fitting

PN 15 Socket mechanical incore type 25

8. Marking

The following items of information shall be marked on the outer surface

of fittings by a reliable method to prevent fading.

( 1) Kind of pipe or its abbreviation .

• (2) Nominal diameter.

(3) Manufacturerts name or its abbreviation.
