由夹口长度为(152±10)mm、总质量为(0.45±0.05)kg的金属弹簧夹夹持试样的另一自由端,试样测
试面接受喷淋。称量尺寸为(152±10)mm×(229±10)mm的白色吸水纸的质量,精确至0.1g,并将其
插入试样与测试台之间。
10.2 将(500±10)mL试剂倒入试验仪的漏斗中开始喷淋试样,倒水过程中宜尽量避免出现漩涡现象。
10.3 喷淋结束后(持续喷淋停止后2s),小心取出吸水纸,并迅速称量吸水纸的质量,精确至0.1g。
11 结果计算和表示
以试验中吸水纸质量的增加量作为渗透量,计算至少3块试样的平均值,以“g”为单位。
当试样的测试结果平均值或单个试样的测定值超过5g的可简记为“+5g”或“ >5g”。
12 试验报告
试验报告应包括以下内容:
b) 样品描述;
c) 测试试样的数量;
d) 调湿与试验用大气条件;
e) 试验测试面及测试结果,必要时给出单个试样的测试值;
f) 试验中任何偏离本标准的细节。

Foreword
This Standard was drafted as per the rules specified in GB/T 1.1-2009 and GB/T
20000.2-2009.
This Standard adopts re-drafting method to modify and use ISO 18695.2007 Textiles
– Determination of Resistance to Water Penetration – Impact Penetration Test.
Compared with ISO 18695.2007, this standard has the major technical differences and
causes as follows.
--- On the normative reference documents, this Standard has made the adjustment
of technical differences, so that adapt to China’s technical conditions; the
adjustment situations focus on reflecting on the Clause 2 “Normative
References”; use GB/T 6529 that modifies and adopted the international
standard to replace ISO 139 (see Clause 8).
--- Modify two instrument physical diagrams in ISO 18695.2007 into schematic
diagram; delete the corresponding 7.1.1 and 7.1.2, so that facilitate the
understanding of the corresponding clauses.
--- Supplement the contents of Item f) in Clause 12 of ISO 18695.2007; add the
report test surface and report value situations, so that the report can be more
complete.
For ease of use, this Standard made the following editorial changes as follows.
--- Modify the terminology in 3.1 of ISO 18695.2007 into “resistance to penetration
by water”;
--- Adjust the Footnote 1 and Footnote2 in ISO 18695.2007 into the NOTEs in 7.1
and 7.2; and simplify them;
--- Adjust the metal spring clip quality requirements in structural diagram of ISO
18695.2007 into consistence with the requirements specified in 10.1;
--- Adjust the relative positions of each view in the structural diagram of ISO
18695.2007;
--- Adjust the order of Item e) and Item f) in Clause 12 of ISO 18695.2007.
This Standard was proposed by China National Textile and Apparel Council.
This Standard shall be under the jurisdiction of National Technical Committee for
Standardization of Textiles (SAC/TC 209).

Textiles – Determination of Resistance to
Water Penetration – Impact Penetration Test
1 Scope
This Standard specifies the test method to measure the fabric resistance to water
penetration under the low impact conditions. This method can be used to predict the
anti-rain and pervaporation properties of fabrics.
This Standard is applicable to the fabrics been subject to or not been subject to the
(GB/T 14577) or leaching method (GB/T 23321), this method is more suitable for
fabrics with medium loose structures.
This Standard is not applicable to the fabrics that can’t be flattened under certain
tension conditions.

8 Atmosphere for Conditioning
Perform conditioning against the specimen according to the standard atmospheric
shall be performed at least 4h.

with metal spring clip, the clip-mouth length of metal spring clip is (152±10) mm; clamp
the other end of specimen by the metal spring clip with clip-mouth length of (152±10)
Weigh the mass of white absorbent paper with size of (152±10) mm × (229±10) mm,
accurate to 0.1g; and insert it in between the specimen and test bench.
10.2 Pour (500±10) mL of reagent into the funnel of tester to start spraying; try to
avoid the swirl phenomenon during water pouring process.
10.3 After the spraying (2s after continuous spraying stops), carefully take out the
absorbent paper, swiftly weigh the mass of absorbent paper, accurate to 0.1g.
11 Result Calculation and Expression
Take the increasing amount of absorbent paper mass in the test as the penetration
amount; calculate the average value of at least 3 blocks of specimens, in “g”.
exceeds 5g, it can be expressed by “+5g” or “>5g” simply.
