EPDM Body Seals

Quality Requirements

3 types: A, C, D

Previous issues

TL 52641: 2005-06

Changes

The following changes have been made compared with TL 52641: 2005-06:–TL (Technical Supply Specification) entirely revised–Types B, C, E, and F correspond to type C in the new version–Types D and C now correspond to type D

Scope

This Technical Supply Specification defines the material requirements for interior and exterior partsthat are subjected to dynamic loads and manufactured from EPDM, e.g., window guides, windowweatherstrips, window and window frame seals, door seals, cover seals, sunroof seals, roof trimstrips, etc.

Requirements for surface coatings, e.g., flock, anti-friction coatings or the like, welt materials, moldedparts, additional integrated body seals, composite materials, and bonding materials as well as ma‐terial-specific component properties are likewise part of this standard. If required, reference is madeto the relevant specific standards for the materials used.

RESIDUAL ALIGNING MOMENT TEST

残余回正力矩试验

Foreword—This Document has not changed other than to put it into the new SAE

Technical Standards Board format.

前言：这个文件并没有改变，除了把它变成新的SAE技术标准委员会格式。

1. Scope—This SAE Recommended Practice describes the determination of tire pull

force properties for an uninclined tire (SAE J670e) on a laboratory flat surface tire

force and moment machine. It is suitable for accurately determining pull forces and

residual aligning moments for passenger and light-truck tires. These properties are

important determinants of vehicle trim (See section 2.1.2). They describe steady-state,

freerolling pull effects ascribable to tires.

范围：这个SAE工业标准描述一个倾斜轮胎（SAEJ670e）在试验室平带力和力矩试验机测定轮胎牵引力特性。它精确地测定PCR和LTR轮胎的牵引力和残余回正力矩。这些特性是车辆轮胎的重要决定因素（见2.1.2节）。它们描述轮稳态胎在自由滚动状态下的牵引作用。

The test method described in this document is suitable for comparative evaluation of
